The manufacturing process of PCBN tool 1.PCBN tool embryo synthesis PCBN composite sheet is directly in the high temperature and high-pressure CBN layer and cemented carbide substrate composite together. After cutting, welding technology into a variety of welding molding cutting tools or blades. Synthetic equipment used in foreign synthetic equipment for the two-sided top press, most of the domestic six-sided top press. 2. PCBN tool geometric parameters The service life of the PCBN tool is closely related to its geometric parameters. Chip removal ability and heat dissipation ability. The size of the front Angle directly affects the stress of the cutting edge and the internal stress of the blade. In order to avoid excessive tensile stress caused by mechanical impact on the tooltip, a negative front Angle (-5) is generally adopted.~ -10. At the same time, in order to reduce back Angle wear, the primary and secondary back Angle is 6., the radius of the tooltip is 0.4 -- 1.2mm, and the chamfering is ground and smooth. is a good precision equipment for grinding the PCBN tool. 3. PCBN tool inspection In addition to testing hardness index, mild bending resistance, tensile strength, and other physical properties. It is more necessary to use a high power electron microscope to check the surface of the PCBN tool and blade processing accuracy. Then there is dimensional inspection, precision inspection, M value, as well as geometric and positional tolerance, roughness, and then packaging and storage.

CNC-työkalunjyrsinkoneella on korkea joustavuusaste ja se voi vastata yksilöityyn tuotantotarpeeseen reaaliaikaisesti. Se on kehittynyt nopeasti viimeisen kymmenen vuoden aikana, ja jopa perinteiset mekaaniset puristimet ovat alkaneet käyttää CNC-teknologiaa.Kuten tiedämme, nykyaikaisessa metallinleikkauskäsittelyssä työkalukustannukset muodostavat vain osan kokonaisvaltaisesta valmistuskustannuksesta, mutta kattava käsittelykustannus muodostaa ratkaisevan osan. Siksi työkalun kustannusten hallinnan lisäksi on parempi käyttää työkalua järkevästi, parantaa tuotantotehokkuutta täysimääräisesti, lyhentää käsittelyaikaa ja loppujen lopuksi vähentää kustannuksia käsittelykustannusten vähentämisellä.Koneenmyyntiprosessimme aikana keskustelemme usein asiakkaidemme kanssa siitä, miksi he haluavat ostaa CNC-työkalunhiomakoneen. Yleensä saamamme vastaus on se, että loppukäyttäjien vaatimukset työkaluille ovat yhä korkeammat. Aiemmin yksinkertaisella ja manuaalisella laitteella hiottujen työkalujen tarkkuus ja muoto eivät enää täytä loppukäyttäjien käsittelyvaatimuksia.CNC-työkaluhiomakoneen työtason rakenteellinen suunnittelu建筑的结构设计CNC-työkalun hiomakoneTyökalupenkki tavallisesti täyttää seuraavat vaatimukset:1. Työkalun hiominen vaatii usein, että kaikkien leikkaavien pintojen karkea koneistaminen suoritetaan yhdellä kiinnityksellä, ja työpöydän pitäisi pystyä käsittelemään useita hiomapyöriä.2. PCD-työkalunhiomakoneessa työkalu koostuu pääasiassa erilaisista monimutkaisista koverista pinnoista, joten työpöydän rakenteen on täytettävä moniakselisen yhteistoiminnallisen käsittelyn vaatimukset varmistaakseen, että jokainen liiketoimenna ei tuota liiketoiminnan häiriöitä työskentelyalueella.Työpöydän on kyettävä kestämään karkean hionnan aikana syntyvä erittäin suuri jännitysvoima, mutta sen on myös varmistettava korkea tarkkuus viimeistelytyössä. Siksi koneistolle asetetaan vaatimukseksi hyvä jäykkyys, hyvä vakaus, korkea liikkeen tarkkuus ja alhainen lämpödegeneraatio.

Requirements OF BT-200 tool grinder When operating BT-200 universal tool grinder, check that the electrical system (motor, distribution box, safety light, wire, grounding wire) is good. No short circuit and the surrounding environment should clean. Lubricate the oil in the lubrication area as specified in the Piston Cup Foreign Grinding Machine Instructions. Turn on the main power supply, start the motor such as the oil pump. In turn, pay attention to the operating status, and find the abnormality. If the difference is abnormal, the power should turn off immediately. And the vehicle should drive after inspection. Start the piston cup foreign grinding machine, idle for 3min. Check whether the movements of each part are normal. Whether the sound is normal, and whether the coolant is unblocked. Before installing the grinding wheel, the grinding wheel should protect from moisture. And the grinding wheel should test for static balance. It is forbidden to have cracks in the grinding wheel. When installing the grinding wheel, it is necessary to pad the paper pad between 0.5-1.0mm between the grinding wheel and the pressure plate and use a special wrench to evenly tighten it. Do not use the long tube to tighten, so as not to cause the grinding wheel to burst. is used frequently in factories and other places. In order to reduce the possibility of accidents during the whole operation, we need to do some preparatory work before using it. The specific requirements are as follows. Before the preparation PCD&PCBN insert grinding machine, first check the environment to be used by the tool grinder to ensure that there is no debris in the entire operating space. So as to avoid the occurrence of damage caused by the debris. Estimate the maximum force required for the upcoming lifting operation in order to select the right tonnage tractor to work in order to avoid the danger of overloading. Safety inspection of each component of the selected tractor and timely maintenance of components with abnormal conditions to reduce the possibility of emergencies during use. Eliminate errors of BT-200 universal tool grinder BT-200 universal tool grinder There are three main methods for eliminating errors. Automatic control method. Let the processing system form an automatic processing cycle system. So that the measurement, adjustment and other work can do automatically in the process of the process, the trial cutting method. Through the trial cutting, some rules can find to eliminate the error. The sizing tool method uses a tool with a certain shape and size to meet the shape and size of the processing requirements. When the water and oil quantity of the Universal tool grinder water tank is insufficient, it needs to be added in time. When processing, it is necessary to timely repair the processed parts, and then check if there is no problem before starting normal use. The process should sharpen with sharp diamonds and coolant is required. Technical analysis of tool grinding machines. First, check the level. If the level of the machine's foot screw is not adjusted, it will cause the machine to resonate. Because sometimes the ground level of the processing site is not very good, it is necessary to adjust the horizontal screw to make the machine reach an uneven height. First, we must check whether each screw of the foot is put into place in the floor mat. Before and after the level is used, the left and right sides are horizontal and the screws are locked.    

The dressing method of the diamond grinding wheel dresser is an important factor affecting the grinding performance of the grinding wheel. The reasonable selection of dressing method will directly affect the surface quality and grinding precision of the workpiece. At present, the commonly used dressing methods of diamond grinding wheel dressing machines include on-line electrolytic dressing, EDM grinding wheel dressing, cup grinding wheel dressing, electrochemical-mechanical compound dressing, and laser dressing. Since the dressing method of the cup wheel is simpler and easier to implement than other dressing methods, GC cup wheel dressing technology is adopted in this paper for the automatic dressing of diamond wheel dresser.The dressing of the superhard abrasive wheel of the diamond grinding wheel is usually divided into two stages: shaping and sharpening. The purpose of shaping is to remove the shape error and surface defect of the grinding wheel after initial installation and to ensure the geometric shape precision of the grinding wheel. Sharpening is due to the passivation of the grinding wheel after working for a period of time. In order to make the cutting edge protruding the binder and having an appropriate height, sufficient chip tolerance space should be formed between the grinding grains, and the effective number of grinding grains per unit area should be as large as possible.

The improvement and development of turning tool material are one of the important issues in the development of metal processing today because good tool material can effectively and quickly complete the cutting work, and maintain a good tool life. Commonly used turning tool material has the following kinds. Types and uses of turning tools 1. High carbon steel A high carbon steel turning tool is a kind of carbon steel with a carbon content between 0.8% and 1.5%. It is used after quenching and hardening. The use range of high carbon steel turning tools is not very wide, usually only suitable for cutting of soft metal materials, commonly used are SK1, SK2, SK7 and so on. 2. High-speed steel High-speed steel is a kind of steel base alloy common name white turning tool, carbon steel of 0.7~0.85% carbon content is added W, Cr, V, and Co alloy elements. The friction heat generated in the cutting of high-speed steel turning tools can reach up to 6000C, suitable for turning the speed below 1000rpm and the thread. 3. Non-cast iron alloy cutting tools This is the alloy of cobalt, chromium, and tungsten, because cutting processing is very difficult, to casting forming manufacturing, so it is also called super hard casting alloy, the best representative is stellite. Its tool toughness and wear resistance is excellent, at 8200C temperature, its hardness is still not affected, far more than high-speed steel, suitable for high speed and deeper cutting work. 4. Sintering carbonization tool The carbide tool is the product of powder metallurgy, the main component of tungsten carbide tool is 50%~90% tungsten, and add titanium, molybdenum, tantalum and other cobalt powder as the binding agent, then through heating sintering. Carbide cutting tools of hardness is higher than any other material, has the hardest three times of high carbon steel, suitable for cutting hard metal or stone material, because it's material brittle hard. So can only be made into a sheet, welded again in its toughness on the handle, so the blade passivation or split, can change another new blade, blade or change this enough tool called abandon type lathe tool. 5. Ceramic turning tool Ceramic turning tool is made of aluminum oxide powder, add a small number of elements, and then through high-temperature sintering, its hardness, thermal resistance, cutting speed is higher than tungsten carbide, but because of brittle, it is not suitable for discontinuous or heavy turning, only suitable for high-speed precision cutting. 6. Diamond cutter For advanced surface processing, diamonds with round or edge edges can be used for optical processing. A smoother surface can be obtained, which is mainly used for precise turning of copper or light alloys. High turning speeds must be used, with a minimum of 60~100m/min and usually 200~300m/min. 7. Boron oxide Cubic boron oxide (CBN) is a widely used material in recent years, and its hardness and wear resistance are relatively strong, second only to diamond. CBN tools are suitable for hard and wear-resistant machining of iron alloys, nickel-based alloys, and cobalt-based alloys.

With the development of automatic numerical control grinding technology, when grinding work in various industries, in order to improve the work efficiency of grinding, high requirements are put forward on the supporting equipment of the grinding machine equipment. As one of the supporting technologies, the online automatic grinding wheel dressing technology must meet the needs of modern CNC grinding technology and developments in the direction of high precision, ultra-stable, and fully automatic control according to the needs of users. PCD TOOL grinding wheel dressing machine is now used as an efficient grinding tool in the grinding industry, widely used in the processing of ceramics, cemented carbide, CBN, and other superhard materials. The equipment not only can grind quickly, but also has high precision, so it is now well received by users in the grinding industry.China Demina BT-150D tool grinding machine is specialized in PCD and CBN tools grinding. It is a four-axis CNC tool grinder, which is composed of four axes, such as the swing axis of the grinding wheel (X-axis), the tilt angle of the grinding wheel (B-axis), the rotation axis in the horizontal plane of the workpiece (C-axis) and the workpiece feed axis (Y-axis). The machine is suitable for medium and large quantities of alloy inserts, PCD inserts, and CBN inserts. As long as the center is completed, the system will automatically complete grinding under the action of the gravity of the hammer, realizing the ideal state of “constant pressure grinding, flexible feed”.Due to the high hardness of diamond material (PCD), the grinding wheel wears quickly. The system can detect and compensate the wear automatically, and maintain the dimensional accuracy of grinding for a long time.

Common tool materials in tool grinding are high-speed steel, powder metallurgy high-speed steel, carbide and PCD, CBN, cermet and other superhard materials. High-speed steel tool sharp, good toughness, hard alloy tool hardness but poor toughness. The density of the carbide tool is obviously higher than that of a high-speed steel tool. These two materials are the main materials for drill, reamer, milling cutter, and tap. Powder metallurgy high-speed steel, whose properties are between the above two materials, is mainly used for making rough milling cutters and taps. A high-speed steel tool is not sensitive to the collision because of its good toughness. But hard alloy tool hardness is high and brittle, very sensitive to the collision, the edge is easy to jump. Therefore, in the process of grinding, the operation and placement of carbide tools must be very careful to prevent the collision between the tools or tool fall. Due to the high-speed steel tool accuracy is relatively low, its grinding requirements are not high, plus its price is not high, so, many manufacturers set up their own tool workshop for its grinding. But hard alloy tools often need to be sent to the professional grinding center for grinding. According to statistics from the China Tool Repair and Grinding Center, more than 80% of repair tools are carbide tools.

As we all know, under the premise of the continuous development of the domestic economy, the development trend of the PCD tool grinders is going up all the way. Businesses have high requirements for modern metal cutting processing technology, and tool costs occupy a small part of the overall manufacturing costs. In order to better solve this kind of phenomenon, in addition to the cost of the PCD tool itself, the CNC mold business uses the tool reasonably to fully improve the production efficiency, shorten the processing time, and ultimately reduce the product cost.PCD tool grinding machine is a machine tool that cuts the surface of a workpiece as a tool, collectively referred to as a grinding machine. Manual PCD tool grinder can process a variety of surfaces, such as internal and external cylindrical and conical surfaces, flat surfaces, gear tooth profiles, spiral surfaces, and various molding surfaces, etc. It can also sharpen tools and cut off, etc. The process range is very wide. Because the grinding process is easy to obtain high machining accuracy and good surface quality, the grinder is mainly used for the finishing of parts, especially the finishing of hardened steel parts and high-hardness special materials. Then the PCD tool grinding machine is in the tool grinding work. What work does the PCD tool need to do?Grinding Work Of PCD Tool Grinding MachineClamping and adjustment of PCD toolsFirst, adjust the center of rotation of the cross table to coincide with the center of the optical projector. Then according to the requirements of the drawing, the PCD tool is adjusted to the reference line of the optical projector through the cross table, and this position is the sharpening position. In order to ensure the accuracy requirements of PCD tools, all sharpening dimensions should be completed in one clamping. If PCD tools are grinding, all wear must be removed.Oscillation parameters of diamond grinding wheelSince diamond grinding wheels are relatively expensive, in order to make full use of the efficiency of the grinding wheel and prevent the occurrence of groove marks, according to the size of the PCD tool, attention should be paid to the amplitude of its swing. By adjusting the swing amplitude and frequency of the grinding wheel swing frame of the sharpening machine tool, the grinding wheel and tool The degree of coincidence are greater than or equal to 1.Minimum grinding allowance for PCD toolsUsually, in the process of tool making, the cost of sharpening is the highest, and the goal is to minimize the amount of removal. The minimum machining allowance depends on the depth of damage to the PCD caused by the cutting method and heating process. It consists of three parts: the first is the depth of damage to the surface layer by the cutting method; the second is the depth of damage to the internal tissue by the cutting method; the third is the influence of the heating method.
