CNC machining tool concept



A tool is a tool used for cutting in mechanical manufacturing. Generalized cutting tools include both cutting tools and abrasive tools. The vast majority of knives are used for machines, but there are also hand tools. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood as a metal cutting tool. The cutting tools used for cutting wood are called woodworking tools.


CNC machining tool



Tool classification

Cutting tools can be divided into five categories according to the form of the workpiece machined surface.

Cutting tools for processing various outer surfaces, including cutting tools for processing various outer surfaces, including turning tools, planing knives, milling cutters, outer surface broach and file, etc.

Hole processing tools, including drill, reaming drill, boring cutter, milling cutter and internal surface broach, etc.

Thread processing tools, including tap, die, automatic opening thread cutting head, thread turning tool and thread milling cutter.

Gear processing tools, including hob, gear shaper cutter, shaving cutter, bevel gear processing tool, etc.

Cutting tools, including inserted circular saw blade, band saw, bow saw, cutting tool and saw blade milling cutter, etc.

In addition, there are combination tools.


Hole cutting tool



Tool structure

The structure of various tools is composed of a clamping part and a working part. The clamping part and working part of the overall structure of the tool are done on the tool body; The working part of the tool (the tooth or blade) is mounted on the tool body.

The clamping part of the tool has two kinds of holes and handles. The tool with hole relies on the inner hole set on the spindle or mandrel of the machine tool, and transmits the torsional torque with the help of the axial key or the end key, such as the cylindrical milling cutter and the sleeve face milling cutter.

The tool with the handle is usually rectangular handle, cylindrical handle and conical handle three kinds. Turning tools, planing tools, etc. are generally rectangular handles; The conical handle withstands the axial thrust with the taper and transmits the torque with the help of friction. Cylindrical shank is generally suitable for smaller twist drill, end mill and other tools, cutting with the help of the friction generated when clamping torque transfer. The shank of many tools with handles is made of low alloy steel, and the working part is made of high speed steel welded to each other.



The basic properties that the tool material should have

1. High hardness

The hardness of the tool material must be higher than the hardness of the workpiece material to be machined, which is the basic feature that the tool material should have.

2. Sufficient strength and toughness

The material of the cutting part of the tool must withstand great cutting force and impact force when cutting. The bending strength and impact toughness reflect the ability of tool material to resist brittle fracture and edge breakage.

3. High wear resistance and heat resistance

The wear resistance of tool materials refers to the ability to resist wear. The higher the hardness of the tool material, the better the wear resistance; The higher the high temperature hardness, the better the heat resistance, the tool material at high temperature resistance to plastic deformation, anti-wear ability is also stronger.

4. Good thermal conductivity

Large thermal conductivity means good thermal conductivity, and the heat capacity generated during cutting is easily transmitted out, thereby reducing the temperature of the cutting part and reducing tool wear.

5. Good technology and economy

In order to facilitate manufacturing, the tool material is required to have good machinability, including forging, welding, cutting, heat treatment, grindability and so on. Economy is one of the important indexes to evaluate and promote the application of new tool materials.

6. Resistance to bonding

Prevent the workpiece and the tool material molecules under the action of high temperature and high pressure adsorption bond.

7. Chemical stability

It means that the tool material is not easy to react chemically with the surrounding medium at high temperature.

Tool coating

Aluminum alloy indexable inserts are now coated with hard or composite layers of titanium carbide, titanium nitride, alumina by chemical vapor deposition. The physical vapor deposition method that is being developed can be used not only for aluminum alloy tools, but also for high-speed steel tools such as drills, hobs, taps and milling cutters. As a barrier that prevents chemical diffusion and heat conduction, the hard coating slows down the wear rate of the tool during cutting, and the life of the coated blade is about 1 to 3 times higher than that of the uncoated blade.




How to choose a tool



Tool selection is carried out in the human-machine interaction state of NC programming. The tool and handle should be correctly selected according to the machining capacity of the machine tool, the performance of the workpiece material, the processing procedure, the cutting amount and other relevant factors.

The general principle of tool selection: easy installation and adjustment, good rigidity, high durability and accuracy. On the premise of meeting the processing requirements, try to choose a shorter tool handle to improve the rigidity of the tool processing. When selecting the tool, the size of the tool should be adapted to the surface size of the workpiece to be machined.

1. End milling cutter is often used to process the peripheral outline of plane parts.

2. When milling the plane, carbide blade milling cutter should be selected.

3. When processing convex and grooves, choose high-speed steel end milling cutter.

4. When processing the blank surface or roughing the hole, you can choose the corn milling cutter with cemented carbide blade.

5. For the processing of some vertical surface and variable bevel contour, ball end milling cutter, ring milling cutter, conical milling cutter and disk milling cutter are often used.

6. In the processing of free-form surface, because the cutting speed of the end of the ball head tool is zero, so in order to ensure the processing accuracy, the cutting line spacing is generally very dense, so the ball head is often used in the finishing of the surface.

7, flat head tool in the surface processing quality and cutting efficiency are better than the ball head knife, therefore, as long as the premise of ensuring but cutting, whether it is rough surface machining or finishing, should be preferred to choose flat head knife.

8. In the machining center, various tools are installed on the tool library, and the tool selection and tool change are carried out at any time according to the procedure. Therefore, the standard tool handle must be used in order to make the standard tool for drilling, boring, expanding, milling and other processes quickly and accurately installed on the machine spindle or tool library. The number of tools should be reduced as far as possible; After a tool is installed, it should complete all the processing parts that it can carry out; Rough finishing tools should be used separately, even if the same size specifications of the tool; Milling before drilling; Surface finishing is carried out first, and then 2D contour finishing is carried out. Where possible, the automatic tool change function of CNC machine tools should be used as much as possible to improve production efficiency.


Problems encountered in processing aluminum and solutions



Problems encountered in processing aluminum and solutions when processing pure aluminum, easy to stick knife analysis and solutions:

1. Aluminum material is soft in texture and easy to stick at high temperature;

2. Aluminum is not resistant to high temperature, easy to open;

3. Related to processing cutting fluid: good oil lubrication performance; Good water-soluble cooling performance; High dry cutting cost;

4. When processing pure aluminum, the end mill dedicated to aluminum processing should be selected: positive front Angle, sharp cutting edge, large chip discharge slot, 45 degrees or 55 degrees helix Angle;

5. The material of the workpiece and the CNC tool has a greater affinity.

6. Rough front tool processing soft materials.

Recommendation: Machine tool conditions are poor to good requirements are low to high, please use high-speed steel, coated polished carbide, PCD polycrystalline diamond and single crystal diamond.

7. Low speed can be avoided by cutting fluid, high speed oil mist lubrication, the effect can be improved, aluminum alloy suitable


Tool future development direction



Due to the high temperature, high pressure, high speed, and the parts working in the corrosive fluid medium, the application of difficult to process more and more materials, the automation level of cutting processing and the processing accuracy requirements are getting higher and higher. In order to adapt to this situation, the development direction of the tool will be the development and application of new tool materials; Further develop the vapor deposition coating technology of the tool, and deposit higher hardness coating on the matrix of high toughness and high strength, so as to better solve the contradiction between hardness and strength of the tool material; Further development of indexable tool structure; Improve the manufacturing accuracy of the tool, reduce the difference in product quality, and optimize the use of the tool.How to choose CNC aluminum alloy machining tool.

No machine can be made without holes. To connect the parts together, a variety of different sizes of screw holes, pin holes or rivet holes are required; In order to fix the transmission parts, various mounting holes are needed; The machine parts themselves also have many kinds of holes (such as oil holes, process holes, weight reduction holes, etc.). The operation of machining holes so that the holes meet the requirements is called hole machining.

The surface of the inner hole is one of the important surfaces of the mechanical parts. In mechanical parts, parts with holes generally account for 50% to 80% of the total number of parts. The types of holes are also diverse, there are cylindrical holes, conical holes, threaded holes and shaped holes. Common cylindrical holes are divided into general holes and deep holes, and deep holes are difficult to process.





Advantages of U drill


1. First of all, the difference between U drill and ordinary drill is that U drill uses the peripheral blade and the center blade, at this Angle, the relationship between U drill and ordinary hard drill is actually similar to the relationship between the machine clamping turning tool and the welding turning tool, and the blade can be replaced directly after the tool is worn without regrinding. After all, the use of indexable blades still saves material than the whole hard drill, and the consistency of the blade makes it easier to control the size of the part.

2. The rigidity of U drill is better, you can use a high feed rate, and the processing diameter of U drill is much larger than that of ordinary drill, the maximum can reach D50~60mm, of course, U drill can not be too small due to the characteristics of the blade.

3.U drill encounter a variety of materials only need to replace the same type of different grades of blade, hard drill is not so convenient.

4. Compared with hard drilling, the precision of the hole drilled by U drilling is still higher, and the finish is better, especially when the cooling and lubrication are not smooth, it is more obvious, and U drilling can correct the position accuracy of the hole, and hard drilling can not be done, and U drilling can be used as a bore knife.





Advantages of U drill in CNC machining


1. U drill can punch holes on surfaces with inclination angles less than 30~ without reducing cutting parameters.

2. After the cutting parameters of U drilling are reduced by 30%, intermittent cutting can be achieved, such as processing intersecting holes, intersecting holes, and phase perforation.

3. U drilling can realize the drilling of multi-step holes, and can boring, chamfer, eccentric drilling.

4. When drilling, the drilling chips are mostly short chips, and the internal cooling system can be used for safe chip removal, without cleaning the chips on the tool, which is conducive to the continuity of the processing of the product, shorten the processing time and improve efficiency.

5. Under the condition of standard length-diameter ratio, no chip removal is required when drilling with U drill.

6. U drill for indexable tool, blade wear without sharpening, more convenient replacement, and low cost.

7. The surface roughness value of the hole processed by U drilling is small, and the tolerance range is small, which can replace the work of some boring tools.

8. The use of U drilling does not need to pre-punch the center hole, and the blind hole bottom surface processed is relatively straight, eliminating the flat-bottom drill.

9. The use of U drilling technology can not only reduce drilling tools, and because U drilling is the head of the cemented carbide blade, its cutting life is more than ten times the ordinary drill, at the same time, there are four cutting edges on the blade, blade wear can be replaced at any time cutting, the new cutting saves a lot of grinding and replacing the tool time, can improve the average efficiency 6-7 times.





U drill in the use of CNC machine tools skills


1. When using U drill, the rigidity of the machine tool and the neutrality of the tool and the workpiece are high, so U drill is suitable for use on high-power, high-rigidity and high-speed CNC machine tools.

2. When using U drilling, the center blade should be used with good toughness, and the peripheral blade should be used with relatively sharp blades.

3. When processing different materials, should choose different groove blade, under normal circumstances, small feed, small tolerance, U drilling length to diameter ratio, choose the groove blade with smaller cutting force, on the contrary, rough machining, large tolerance, U drilling length to diameter ratio is small, then choose the groove blade with larger cutting force.

4. When using U drilling, we must consider the power of the machine tool spindle, the stability of U drilling clamping, the pressure and flow of cutting fluid, and control the chip removal effect of U drilling, otherwise it will greatly affect the surface roughness and dimensional accuracy of the hole.

5. When installing the U drill, it is necessary to make the U drill center coincide with the center of the workpiece and be perpendicular to the surface of the workpiece.

6. When using U drilling, the appropriate cutting parameters should be selected according to different parts materials.

7. When drilling test cutting, be sure not to reduce the feed or speed at will because of caution and fear, so that the U drill blade is damaged or the U drill is damaged.

8. When using U-drill processing, when the blade is worn or damaged, it is necessary to carefully analyze the reasons and replace the blade with better toughness or more wear-resistant.

9. When using U drill to process step holes, it is necessary to start processing from large holes and then process small holes.

10. When drilling, pay attention to the cutting fluid to have enough pressure in order to flush out the chips.

11. The blade used on the center and edge of the U drill is different, must not be misused, otherwise it will damage the U drill rod.

12. When drilling with U-drill, workpiece rotation, tool rotation, and simultaneous rotation of the tool and workpiece can be used, but when the tool is moved in a linear feed mode, the most common method is to use the workpiece rotation mode.

13. The performance of the lathe should be considered when machining on the CNC car, and the cutting parameters should be adjusted appropriately, generally reducing the speed and low feed.





U drill in CNC machining often appear problems


1. The blade is damaged too fast, easy to break, and the processing cost increases.

2. A harsh whistle is emitted during processing, and the cutting state is abnormal.

3. Machine jitter, affecting the machining accuracy of machine tools.



U drill use points to note


1. The installation of U drill should pay attention to the positive and negative directions, which blade is up, which blade is down, which is facing inside and which is facing outside.

2. The center height of U drilling must be corrected, according to its diameter size to require the control range, generally controlled within 0.1mm, the smaller the diameter of U drilling, the higher the center height requirements, the center height is not good U drilling two sides will wear, the aperture will be larger, the blade service life will be shortened, small U drilling is easy to break.

3. U drill has very high requirements for coolant, it must be ensured that the coolant is emitted from the center of U drill, the greater the pressure of the coolant, the better, the excess water outlet of the tower can be blocked up to ensure its pressure.

4, U drilling cutting parameters in strict accordance with the manufacturer's instructions, but also to consider different brands of blades, machine power, processing can refer to the load value of the machine tool size, make appropriate adjustments, generally using high speed, low feed.

5.U drill blade to check often, timely replacement, different blades can not be installed reverse.

6. According to the hardness of the workpiece and the length of the tool suspension to adjust the feed amount, the harder the workpiece, the larger the tool suspension, the smaller the cutting amount.

7. Do not use excessive wear of the blade, should be recorded in the production of blade wear and the relationship between the number of workpieces can be machined, timely replacement of new blades.

8. Use sufficient internal coolant with correct pressure. The main function of the coolant is chip removal and cooling.

9.U drill can not be used for processing softer materials, such as copper, soft aluminum, etc.
