Then the order of precision machinery parts processing is divided into what kinds？
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.

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.
What is electroplating? What are the types and applications of electroplating?
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.
What is polishing?
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.

CNC metalworking is growing in popularity due to its ability to mass-produce detailed and precise results, which has led to an increase in the number of producers using CNC machines in the industry.
CNC machining is a manufacturing method in which the tool movement is controlled by pre-programmed computer software. All medical products can be manufactured accurately and quickly with the help of CNC milling and turning. Let's look at the main advantages of CNC machining demand in the healthcare industry:
No fixed tool
CNC machining is unmatched in terms of fast turnaround and minimal investment in small batch production, even in disposable products. Parts for the medical industry often have to be manufactured quickly and in small batches. At the same time, CNC metalworking allows parts to be manufactured without dedicated tools, which can extend the manufacturing process but provide excellent quality and precision even without the use of tools.
No quantity limit
After you create a digital CAD (Computer Aided Design) file, you can easily build a cutting program from it at the touch of a button. The coding application can manufacture a single part or any number of parts with the highest precision and accuracy. This is a huge benefit when creating disposable or disposable custom parts, such as highly specialized medical devices, appliances, equipment, prosthetics, and other medical or surgical products. Other procedures require a minimum order size to obtain the required raw materials, making certain projects impractical, while CNC machining does not require a minimum order size.
High tolerance
Many medical types of equipment require a large tolerance range, and with CNC machines, this is easily achieved. The surface finish is usually very good and requires minimal post-treatment, saving time and money, but this is not the most important consideration. In general, the most important thing to remember about medical supplies and equipment is that they must be fit for their purpose, and any deviation from the standard can mean disaster.
Fast machine
CNC machines are faster and can work 24 hours a day, 365 days a year. Apart from routine maintenance, repairs and upgrades are the only time manufacturers stop using equipment.
Digital CAD files are lightweight and flexible
Product designers, medical specialists, and manufacturing professionals can quickly and easily transfer digital programs from one location to another. The technology significantly improves CNC machining capabilities to produce high-quality specialty medical devices and equipment solutions, regardless of geographic location, whenever and wherever they are needed. This feature of CNC machining is very convenient, especially in time-critical medical environments.
How is CNC Machining changing the healthcare industry

The ability to precisely carve internal cavities, channels, and delicate features is especially valuable when manufacturing implants, microdevices, and surgical instruments.
Rapid prototyping
Prototyping allows medical engineers and designers to create functional models of parts and devices, enabling them to evaluate design, assembly, and functionality before starting production. The combination of computer-aided design (CAD) software and CNC machine tools allows digital designs to be quickly translated into physical prototypes.
This allows for iterative design improvements and helps ensure that medical devices are thoroughly tested and optimized prior to release. In an evolving field, rapid prototyping can enhance innovation and help bring new medical advances to market faster.
Process optimization
The integration of CNC machining with advanced technologies such as automation and artificial intelligence (AI) minimizes errors and enables automated quality control processes. This increases efficiency, reduces production time and improves product quality, all of which contribute to improved patient outcomes.
In addition, automated CNC systems can operate continuously with minimal human-machine interaction between operations. Some CNC machines are also capable of multi-axis machining and performing tasks on different surfaces of parts at the same time.
By reprogramming machines, manufacturers can quickly switch between producing one type of part and another. This reduces conversion times and means that different parts can be made on the same machine in a single shift. These features help speed up production cycles, reduce downtime, and increase overall production.
Flexible material selection
CNC machining is suitable for a wide range of materials, including metals, plastics and composites. This versatility enables manufacturers to consider factors such as biocompatibility, durability and functionality to select the most appropriate material for a specific medical application.
Cost saving
Although industrial CNC machines can be expensive, they offer significant cost saving opportunities in the long run. By eliminating the need for dedicated jigs, fixtures, and dedicated tools for each part, CNC machining helps minimize setup time, simplify production, and reduce manufacturing costs.
The technology also reduces waste and costs through material optimization. This is especially important in the medical field, as implants are often made with high-value materials such as titanium and platinum. The increased efficiency and productivity of CNC machining also contribute to cost savings over time.

Why CNC machining stands out?
Previous machines which were known as numerical control machines (NC) located their positions via G-codes. These G-codes were manipulated manually by the user unlike in CNC machining whereby this task is computerized. In the most recent versions known as the parametric program, logical commands have been fixed in a manner that they can work together with these G-codes. This modified version allows users to regulate and manipulate system parameters effortlessly.
Benefits of using CNC machines:
The improvement in technology used in the manufacturing of these machines has brought about a number of benefits.
These include the following:
- There is improved speed, accuracy, productivity and efficiency of tasks - They significantly reduce the incidents of accidents since computerized systems minimize the contact between the tools and the user. This makes the metalworking process a more comfortable undertaking.
CNC Milling Machines:
CNC milling machines function by using a computerized system to transmit signals to a stepper motor controller. This system instructs the stepper motor on the direction to follow and the number of steps it is supposed to take. The motor is linked to the drive mechanism of the mill in the X, Y and Z axes. Some CNC milling machines are known to utilize a servo motor as a replacement for the stepper motor. They have below mentioned advantages:
- Metals can be cut at higher rates - Servo motors have a feedback loop which enables the machine to accurately resume to its initial position.
