Today's machining industry, traditional machining equipment has been unable to meet the quality needs. CNC machine tool equipment replaces ordinary machine tools, and automatic processing equipment such as precision CNC machining and CNC lathe processing replaces traditional machine tools. The following will take you to understand the advantages of CNC machining machine tools and the order of precision mechanical parts processing.

In the process of machining mechanical parts, CNC machining machine tools have the following advantages:

1.CNC machining center has high precision and high processing quality.CNC machine tools are renowned for their exceptional precision and accuracy.  They use computer-controlled movements and specialized software to perform tasks with minimal error margins.  Unlike human operators, CNC machines consistently reproduce identical parts to exact specifications.

2.CNC machining parts can be multi-coordinate linkage, can process complex shape parts.CNC machine tools offer remarkable flexibility and versatility compared to traditional manual machines.  With the ability to change tooling and adapt to various operations quickly, they are ideal for manufacturing complex and intricate components.

3.CNC machining process change, generally only need to change the numerical control program, can save production preparation time.CNC machine tools offer remarkable time-saving benefits.  Traditional manual machining methods are time-consuming and labor-intensive, requiring extensive set-up and constant manual adjustments.  In contrast, CNC machines can be easily programmed to perform complex operations accurately, greatly reducing production lead times.And CNC machining machine tool itself has high precision, large rigidity, can choose a favorable processing amount, high productivity (generally 3 to 5 times of ordinary machine tools).

4.CNC machining belongs to CNC machining equipment, high degree of automation, can reduce labor intensity.Although the initial investment in CNC machine tools may be higher than manual machines, they offer substantial long-term cost savings.  These machines reduce labor costs since they require fewer operators for operation and supervision.  Moreover, CNC machines minimize material wastage by executing precision cuts and reducing human errors, leading to significant material savings.

5.Increased Productivity and Efficiency.One of the most significant advantages of CNC machine tools is their ability to increase productivity and efficiency. These machines can operate around the clock, minimizing production downtime and maximizing output.  Once programmed, they can perform complex tasks with minimal supervision, freeing up manpower for other critical areas of production.

CNC machine tools have ushered in a new era of production efficiency, accuracy, and cost-effectiveness.  With precision, productivity, flexibility, cost savings, time-saving advantages, and the right skillset, businesses can harness the full potential of CNC machines and stay ahead in the competitive manufacturing industry.

Each processing method has its processing sequence. Our operators need to process in accordance with its processing order, but not disorderly, so that it will have a certain impact on the processed products, or quality problems. Precision machining is one of them, then the order of precision mechanical parts processing is divided into what kinds.

The arrangement of fine parts processing should be based on the structure and blank situation of the parts, as well as the needs of positioning clamping, and the focus is on the rigidity of the workpiece is not destroyed.

• The processing of the previous process can not affect the positioning and clamping of the next process, and the processing process of general fine parts in the middle of the cross should also be considered comprehensively;
• Stop the inner cavity processing sequence first, and then stop the outer shape processing process;
• The process of processing with the same positioning, clamping method or the same knife is best connected and stopped to reduce the number of repeated positioning, the number of tool changes and the number of moving platen. Shenzhen Machining;
• In the same device to stop multiple processes, should be arranged first to the workpiece rigid damage process.

Tool concentration sorting method: It is divided into processes according to the tool used, and all the parts that can be completed with the same tool are processed. In the second knife, the third knife to complete the other parts they can complete. This can reduce the number of tool changes, shorten the idle time, reduce unnecessary positioning errors.

Processing parts sorting method: On the processing content of a lot of parts, according to its structural characteristics will be processed local dividends several parts, such as internal shape, shape, surface or plane. Ordinary first processing plane, positioning surface, after processing holes; First processing simple geometric shapes, then processing complex geometric shapes; The parts with lower precision are processed first, and then the parts with higher precision requirements are processed.

In short, the current precision machinery parts processing technology is very advanced, high quality and high production efficiency.

HONSCN Precision has 20 years of cnc machining experience. Specializing in cnc machining, hardware machinery parts processing, automation equipment parts processing. Robot parts processing, UAV parts processing, bicycle parts processing, medical parts processing, etc. It is one of the high-quality suppliers of cnc machining. At present, the company has hundreds of cnc machining centers, grinding machines, milling machines, high-quality high-precision testing equipment, to provide customers with precision and high-quality cnc spare parts processing services.

Now many industries of precision parts will use CNC machining production, but after CNC machining is completed, many products surface is still relatively rough, this time you need to carry out secondary surface finishing treatment.

First of all, surface treatment is not suitable for all CNC processing products, some products can be directly used after processing, and some need to be hand-polished, electroplating, oxidation, radium carving, screen printing, powder spraying and other special processes. Here are some things you should know about surface treatment.

1, improve product accuracy; After the product processing is completed, some products have a rough surface and leave a large residual stress, which will reduce the accuracy of the product and affect the precision of the match between the parts. In this case, the product surface treatment is required.

2, provide product wear resistance; If the parts usually use scenarios are interacting with other parts, long-term use will increase part wear, which also requires processing of the product surface to extend the service life of the parts.

3, improve the corrosion resistance of the product; Parts used for a long time in highly corrosive places require special surface treatment, requiring polishing and spraying of anti-corrosion materials. Improve corrosion resistance and service life of the product.

The above three points are the prerequisites for surface processing after CNC precision parts processing, and several surface treatment methods will be introduced below.

01. What is electroplating?

Electroplating refers to the surface engineering technology of obtaining a solid metal film on the surface of the substrate by electrolysis in a salt solution containing the metallized group, with the metallized group as the cathode and the metallized group or other inert conductor as the anode under the action of direct current.

02. Why electroplate?

The purpose of electroplating is to improve the appearance of the material, while giving the surface of the material a variety of physical and chemical properties, such as corrosion resistance, decorative, wear resistance, brazing and electrical, magnetic, optical properties.

03. What are the types and applications of electroplating?

1, galvanized

The galvanized layer is of high purity and is an anodic coating. The zinc layer plays a mechanical and electrochemical protective role on the steel matrix.

Therefore, galvanized layer is widely used in machinery, hardware, electronics, instruments, light industry and other aspects, is one of the most widely used plating species.

2. Copper plating

The copper coating is a cathode polar coating, which can only play a mechanical protection role on the base metal. The copper plating layer is usually not used as a protective decorative coating alone, but as the bottom or middle layer of the coating to improve the adhesion between the surface coating and the base metal.

In the field of electronics, such as through hole copper plating on printed circuit boards, as well as hardware technology, crafts, furniture decoration and other fields.

3. Nickel plating

Nickel plating layer is a negative polarity protective layer, which only has a mechanical protection effect on the base metal. In addition to the direct use of some medical devices and battery shells, the nickel-plated layer is often used as the bottom or middle interval layer, which is widely used in daily hardware, light industry, home appliances, machinery and other industries.

4. Chrome plating

The chromium-plated layer is a negative polarity coating, which only plays a mechanical protection role. Decorative chrome plating, the bottom layer is generally polished or electrodeposited bright coating.

Widely used in instruments, meters, daily hardware, household appliances, aircraft, automobiles, motorcycles, bicycles and other exposed parts. Functional chrome plating includes hard chrome plating, porous chrome, black chrome, opal chrome and so on.

Hard chrome layer is mainly used for various measuring calipers, gauges, cutting tools and various types of shaft, loose hole chrome layer is mainly used for cylinder cavity piston failure; The black chrome layer is used for parts that need a dull surface and wear resistance, such as aviation instruments, optical instruments, photographic equipment, etc. Opalescent chromium is mainly used in various measuring tools.

5. Tin plating

Compared to the steel substrate, tin is a negative polar coating, while compared to the copper substrate, it is an anode coating. The tinning layer is mainly used as the protective layer of thin plate in the can industry, and most of the malleable iron skin is made of iron plate tinning. Another major use of tin coatings is in the electronics and power industries.

6, alloy plating

In a solution, two or more metal ions are co-precipitated on the cathode to form a uniform fine coating process called alloy plating.

Alloy electroplating is superior to single metal electroplating in crystal density, porosity, color, hardness, corrosion resistance, wear resistance, magnetic conductivity, wear resistance and high temperature resistance.

There are more than 240 kinds of electroplating alloys, but less than 40 kinds are actually used in production. It is generally divided into three categories: protective alloy coating, decorative alloy coating and functional alloy coating.

Widely used in aviation, aerospace, navigation, automobile, mining, military, instruments, meters, visual hardware, tableware, Musical Instruments and other industries.

In addition to the above, there are other chemical plating, composite plating, non-metal plating, gold plating, silver plating and so on.

The surface of the items processed by CNC machining or 3D printing is sometimes rough, and the surface requirements of the products are high, so they need to be polished.

Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece in order to obtain a bright, flat surface processing method.

Polishing can not improve the dimensional accuracy or geometric accuracy of the workpiece, but for the purpose of obtaining a smooth surface or mirror gloss, and sometimes to eliminate gloss (extinction).

Several common polishing methods are described below:

01. Mechanical polishing

Mechanical polishing is by cutting, plastic deformation of the surface of the material to remove the polished convex and smooth surface polishing method, the general use of whetstone strip, wool wheel, sandpaper, etc., mainly manual operation, surface quality requirements can be used to super-fine polishing method.

Super finishing polishing is the use of special grinding tools, in the polishing liquid containing abrasive, tightly pressed on the workpiece to be machined surface, for high-speed rotation. This method is often used in optical lens molds.

02. Chemical polishing

Chemical polishing is to dissolve the microscopic protruding part of the surface of the material in the chemical medium preferentially than the concave part, so as to obtain a smooth surface.

The main advantage of this method is that it does not require complex equipment, can polish the workpiece with complex shape, and can polish many workpieces at the same time, with high efficiency.

The core problem of chemical polishing is the preparation of polishing liquid.

03. Electrolytic polishing

The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, the surface is smooth by selectively dissolving small protruding parts on the surface of the material.

Compared with chemical polishing, the effect of cathode reaction can be eliminated and the effect is better.

04. Ultrasonic polishing

The workpiece is put into the abrasive suspension and placed together in the ultrasonic field, and the abrasive is ground and polished on the workpiece surface by relying on the oscillation of the ultrasonic wave.

Ultrasonic processing macroscopic force is small, will not cause workpiece deformation, but tooling production and installation is more difficult.

05. Fluid polishing

Fluid polishing relies on high-speed flowing liquid and the abrasive particles it carries to wash the surface of the workpiece to achieve the purpose of polishing.

Common methods are: abrasive jet processing, liquid jet processing, hydrodynamic grinding and so on. Hydrodynamic grinding is driven by hydraulic pressure to make the liquid medium carrying abrasive particles flow through the surface of the workpiece at high speed.

The medium is mainly made of special compounds with good flow under low pressure and mixed with abrasives, which can be silicon carbide powder.

06. Magnetic grinding polishing

Magnetic grinding and polishing is the use of magnetic abrasive under the action of magnetic field to form an abrasive brush, grinding the workpiece.

This method has the advantages of high processing efficiency, good quality, easy control of processing conditions and good working conditions.

The above are 6 common polishing processe.

It is said that in the career of a machine tool worker, no matter how careful it is, it is impossible to avoid a knife collision accident.This has nothing to do with whether the worker is serious and practical and stable, just like a person can not avoid mistakes in the growth process, in the growth process of a machine tool worker, the knife seems to be a hurdle that cannot be bypassing.

Bumping tool, refers to the tool in the process of moving with the workpiece, chuck or tailstock accidental collision machine accident, is the most likely accident for CNC lathe operation novices.

Knife collision will cause workpiece scrap, tool damage, serious damage to the accuracy of the machine tool, destroy the machine parts, and even endanger the personal safety of the machine tool processing personnel.

The occurrence of knife collision accidents is mainly caused by programming errors in the programming process or workers' operational errors in the processing link.

For workers, the general programming link is not easy to make mistakes, and many people have knife collision accidents, often caused by mistakes in the process of machine tool operation.

Because the CNC machining center is locked by software, in the simulation processing, when the automatic operation button is pressed, it is not intuitive to see whether the machine is locked in the simulation interface.

There is often no tool in the simulation, and if the machine tool is not locked to run, it is easy to bump the knife.

Therefore, before the simulation processing should go to the running interface to confirm whether the machine is locked.

1. Forget to turn off the empty running switch during processing.

Because in the program simulation, in order to save time, the empty run switch is often turned on.

Empty operation means that all moving axes of the machine are running at the speed of G00.

If the operation switch is not turned off during the processing time, the machine tool ignores the given feed speed, and runs at the speed of G00, resulting in knife and machine tool accidents.

2. No reference point is returned after running the simulation empty.

In the verification program when the machine is locked motionless, and the tool relative to the workpiece processing in the simulation operation (absolute coordinates and relative coordinates change), then the coordinates do not match the actual position, must use the method of returning the reference point to ensure that the mechanical zero coordinates are consistent with the absolute and relative coordinates.

If the machining operation is carried out without finding the problem after the verification procedure, it will cause the collision of the tool.

3. The direction of overshoot release is not correct.

When the machine overruns, it should press and hold the overruns release button, and move in the opposite direction manually or by hand, that is, it can be eliminated.

However, if the direction of lifting is reversed, it will cause damage to the machine tool.

Because when the overrange release is pressed, the overrange protection of the machine tool will not work, and the stroke switch of the overrange protection is already at the end of the stroke.

At this time, it is possible to cause the workbench to continue to move in the direction of excess, and eventually pull the lead screw, causing damage to the machine tool.

4. The cursor position of the specified line is incorrect.

When a specified line is run, it is usually executed downward from the cursor position.

For the lathe, it is necessary to call the tool offset value of the tool used, if the tool is not called, the tool running the program segment may not be the desired tool, and it is very likely to cause a collision accident due to different tools.

Of course, in the machining center, CNC milling machine must first call the coordinate system such as G54 and the length compensation value of the knife.

Because the length compensation value of each knife is not the same, it is possible to cause knife collision if it is not called.

As a high-precision machine tool, anti-collision is very necessary, requiring the operator to develop the habit of being careful and careful, operating the machine tool according to the correct method, and reducing the occurrence of machine tool collision.

With the development of technology, advanced technologies such as tool damage detection, machine tool anti-impact detection, and machine tool adaptive processing have emerged during processing, which can better protect CNC machine tools.

There are 9 reasons for this:

(‍1) Programming error

The process arrangement is wrong, the process undertaking relationship is not carefully considered, and the parameter setting is wrong.

Example :

A. The coordinate is set to zero at the base, but the top is 0 in practice;

B. The safety height is too low, resulting in the tool can not completely lift out the workpiece;

C. The second opening margin is less than the previous knife;

D. After the program is written, the path of the program should be analyzed and checked;

(2) Program single remarks error

Example:

A. The number of unilateral touches is written in four sides;

B. The clamping distance of the vise or the protruding distance of the workpiece is wrong;

C. The extension length of the tool is unknown or wrong, resulting in knife collision;

D. Procedure sheet should be as detailed as possible;

E. The principle of new for old should be adopted when the procedure is changed:Destroy the old program.

(‍3) Tool measurement error

Example:

A. The tool bar is not considered in the tool data input;

B. The tool is too short;

C. Tool measurement should use scientific methods, as far as possible with more accurate instruments;

D. The length of the tool should be 2-5mm longer than the actual depth.

(4) Program transmission error

Program number call error or program modification, but still use the old program processing; The site processor must check the detailed data of the program before processing; For example, the time and date the program was written and simulated with bear.

(5) Wrong knife selection

(6) the blank exceeds expectations, and the blank is too large and does not conform to the blank set by the program

(7) The workpiece material itself has defects or high hardness

(8) clamping factors, pad interference and the procedure is not considered

(‍9) Machine tool failure, sudden power failure, lightning strike caused tool collision, etc
