With the increasingly updated processing technology, CNC machining has also undergone a lot of changes. Many experts pointed out that in the future, CNC will be the mainstream processing mode. In the CNC machining process, the tool is the most important, today, we will understand the CNC tool in detail.
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.

As a machine tool mainly used to process box and shell parts, the machining center is worth hundreds of thousands to millions. It is generally the key equipment in the key processes of the enterprise. Once the machine is shut down, the loss is often great. Therefore, in order to give full play to the benefits of the machine tool, we must pay attention to the maintenance and repair work. Because most of the daily electrical faults of CNC machine tools are electrical faults, electrical maintenance and repair are more important.1) CNC system control part2) Servo motor and spindle motor
Focus on noise and temperature rise. If the noise or temperature rise is too large, find out whether it is a mechanical problem such as bearing or the parameter setting of its matching amplifier, and take corresponding measures to solve it. For example, if there is abnormal sound during the movement of the servo shaft, and there is no obvious parameter change after verification, it is suspected that the mechanical noise may be caused by the lead screw, coupling and non concentricity with the servo motor. Disconnect the motor from the coupling and operate the motor separately. If the motor still has noise, adjust the speed loop gain and position loop gain appropriately, Make the motor silent. If there is no noise, judge that it is the concentricity between the lead screw and the coupling, re correct the concentricity, and then connect with the motor. The problem can be eliminated.
3) Measurement feedback elementIncluding encoder, grating ruler, etc., check whether the connection of detection elements is loose and whether they are polluted by oil or dust.4) Electrical control part
Check whether the three-phase power supply voltage is normal; Check whether the electrical components are well connected; Check whether various switches are effective with the aid of CRT display diagnosis screen; Check whether all relays and contactors work normally and whether the contacts are in good condition; Whether the thermal relay, arc suppressor and other protective elements are effective; Check whether the temperature of components inside the electrical cabinet is too high. For poor contact of contactor contact, the contactor can be disassembled, the high-temperature oxide on the contact surface can be scraped off with a small file, then the sundries can be wiped out with absorbent cotton and alcohol, reassembled, and then the contact can be conducted with a multimeter.
5) Improve utilization
If the machining center is idle for a long time, when it needs to be used, first of all, each moving link of the machine tool will affect its static and dynamic transmission performance due to grease solidification, dust and even rust, reduce the accuracy of the machine tool, and the blockage of the oil circuit system is a big trouble; From the electrical point of view, the electrical control system hardware is composed of tens of thousands of electronic components, and their performance and life are very discrete. If it is not used for a long time, when power is suddenly transmitted, the components will be damaged in high current and strong voltage. Therefore, in a period of time without machining task, it is best to run the machine tool at a low speed, and at least power on the NC system frequently, or even every day.
I have encountered this situation: a horizontal machining center, using FANUC system. After running the warm-up program, it processed and found that the qualified parts were processed in the morning, and the processed parts were unqualified by noon. After inspection by the on-site processing personnel, the positioning and fixture on the machine tool are not deformed or loose. However, when the spindle box is not processed and stationary, it will deviate downward by 0.1mm along the direction of the gravity axis. The technician judges that the temperature compensation fails or the temperature sensor has poor contact. However, the phenomenon still occurs after replacing the temperature sensor and temperature module and re entering CNC parameters and temperature compensation parameters. After expert consultation, it was finally found that it was not the sensor problem, but that there was a 2-meter-long and 1-meter-wide skylight facing the main shaft and column on the machine tool. At noon, the sun directly shines on the main shaft and column, resulting in thermal deformation. After the skylight is covered, the spindle box returns to normal. This is a typical maintenance error caused by improper maintenance. Therefore, proper daily maintenance provides convenience for overall maintenance in the future.

Long long agoOnce upon a time, people said that the country is an important weaponIt refers to the imperial jade seal handed down by Qin Shihuang on behalf of the heavenly power
Later, it generally refers to the jade seal carved by emperors of all dynastiesOn October 5, 2016, Sotheby's auction house auctioned the Hotan green jade seal "the treasure of the supreme emperor" used by one party after the reign of Emperor Qianlong in Hong Kong for HK $91.48 million. At that time, the auction aroused fierce opposition from many parties in China.Nowadays, the title of national heavy weapon refers to manufacturing equipment
Manufacturing equipment determines the level of processing and manufacturingThe level of processing and manufacturing is an intuitive expression of a country's national strengthHowever, what we are talking about today is only this kind of national manufacturing equipment

As for various high-precision metal partsThere are too many to enumerateThere are turning, boring and milling, grinding and grooving
There are punching, gear shaper and testingThe tools that appear are not completely duplicatedA large CNC machining center
CNC can shape the precision and shape of complex workpieces at one time. What you eat is iron, and what you spit out is different work with high precision. However, the time is hundreds of times shorter than before, and the precision yield has been improved exponentially. The most irritating thing is that it also has adaptability and can be updated at any time.For example, in the past, if a master of worm gear wanted to make a good worm, you had to practice it for ten years and eight years. Hey, now if you want to process a completely different part and make a new process, you can sit and drink coffee. All this needs the support of equipment (tools), that is, it depends on how the manufacturing equipment of this manufacturing equipment plays with the equipmentCNC equipment: all kinds of machining tools
A CNC machining centerBe responsible for tool storage and tool change equipmentIt is called tool holder, also known as tool magazine
We all know the English word: tool magazine(in fact, the original meaning of the word magazine comes from the warehouse)To improve the working ability of CNC
In addition to pursuing more precise controlIt is also necessary to increase the capacity of the tool magazine and speed up the efficiency of tool changeThere are many ways to achieve this
According to the number of tools stored in the tool magazine and the tool taking methodCan be divided into different typesThe common ones are linear type, hat type, disc type, chain type magazine and so on
The power turret should be regarded as the smallest and most portable CNC tool magazineThe utility model is composed of a rotary cutter head and a box bodyA motor is installed in the box

A CNC machining center can install multiple power turretsThe upgraded version of the power turret is a hat type magazineIt is similar to the integration of turret and spindle head
It is a hat type tool magazine that automatically changes tools by moving the spindle up and downWhen the tool on the spindle enters the clamping slot of the hat magazineThe spindle moves up out of the tool
At the same time, the magazine rotates rapidlyWhen the tool to be replaced is aligned below the spindleThe spindle moves down so that the tool enters the spindle taper hole
After clamping the tool, the magazine returns to its original positionThe tool position of hat magazine is still limited (generally 16 34 tool positions)And it's always up and down
It takes up a lot of time and is not efficientIt also affects the working stroke of the spindleHowever, for a universal manufacturing equipment
It is not enough to add several independent tool holdersAfter all, a high-precision CNC machining center needs to coverLathe worker, milling worker, grinder worker, line drawing worker, heat treatment and other links
