Based on the above grinding characteristics of PCD, the requirements for the extension bar of the grinding equipment when grinding PCD with a diamond grinding wheel are much higher than those of the general tool grinder. Mainly include: PCD cutting tool grinding requirements for tooling 1. The machine has a good process system rigidity PCD material has high hardness, so many grinding machine tools use it for grinding work. However, in order to perform high-intensity grinding, the grinding machine must have high resistance to deformation, especially the spindle system and tool clamping system. The grinding force of PCD cutting tools is usually 100 ~ 500N. Therefore, the axial rigidity and strength of the machine tool bearings are required to be able to meet the needs of many users. 2. The machine has a short-range swing mechanism with adjustable stroke and speed The grinding ratio of PCD is extremely low, and the grinding mechanism of PCD is mainly the result of the mixing of micro-crushing, wear, peeling, cleavage and other mechanical effects, oxidation, and graphitization through the continuous impact of diamond grinding wheel on PCD materials. Therefore, the adoption of the short-swing mechanism is beneficial to improve grinding efficiency and cutting edge quality. Generally, the swing distance is 0 ~ 50mm, and the swing speed is 20 ~ 60 times/min. 3. The tool holder of the machine has a high-precision rotary function and online detection device As everyone knows, because PCD materials are hard and fragile and wear-resistant, tooltips are usually designed to be curved to reduce the relative vibration amplitude of the tool and the workpiece to improve grinding efficiency. When the PCD tool is used, in order to achieve the processing of the tooltip, the tool holder of the machine tool should have a high-precision rotation function and an on-line detection device for the tooltip radius size and quality. In this way, positioning errors caused by multiple loadings can be avoided, and processing efficiency can be doubled.

Grinding is widely used and is one of the first methods for fine machining of machine parts. Tool grinders are also commonly used for grinding wheels. However, because the speed of the tool grinding wheel is high, the grinding wheel is relatively hard, brittle, and cannot withstand heavy impacts. Occasionally improper operation can cause very serious results when the wheel is broken. Therefore, the safety and technical work of tool grinding machines are particularly important. Must adopt reliable safety protection equipment, and must focus and ensure the operation. In addition, the fine sand and metal chips splashed on the workpiece of the grinding wheel during the grinding will hurt the workers' eyes. If workers inhale this dust in large quantities, it will be harmful to the body and should adopt appropriate protective measures. Safety technology of tool grinding machine processing should pay attention to the following safety technical issues when grinding. 1. Before starting the machine, you should carefully inspect the machine tool. Including the operating mechanism, electrical equipment, and magnetic chucks. 2. After checking, smooth it again, and then test run it before use. Pay attention to the clamping and clamping when installing the workpiece. During the grinding process, the loosening of the workpiece will cause serious results such as flying out of the workpiece or hurting the grinding wheel. 3. When turning on the machine, use the manual adjustment method to make the grinding wheel close to the workpiece slowly, and the feeding amount at the beginning should small. Do not use excessive force to avoid bumping the grinding wheel. 4. When you need to use the stopper to control the reciprocating motion of the table, adjust it accurately according to the grinding length of the workpiece, and tighten the stopper firmly. 5. When replacing the grinding wheel, you must first check the appearance to see if there is any trauma, and then hit it with a wooden hammer or stick. The sound is crisp and no cracks are required. 6. When installing the grinding wheel, it must be assembled in accordance with the prescribed methods and requirements. After the static balance debugging, we should install and test the device. Only after all are normal, and can use it. 7. Workers should wear protective glasses during work. They should balance the grinding wheel to avoid a collision. Workpiece measurements, adjustments, or scrubbing of the machine are performed after shutdown. 8. When using a magnetic suction cup, wipe the disk surface, the workpiece clean, tight, and stuck firmly. If necessary, you can add an iron stop to prevent the workpiece from shifting or flying out. 9. Attention should be paid to the installation of the wheel guard or the machine baffle, and the station should pass the front side of the high-speed rotating wheel.

Development of accessories for drill sharpener how to make the sharpener's own products and companies more competitive. This is the problem that should be considered when the current enterprise should be the sharpener. As far as the current situation is concerned, the requirements for parts belonging to the world can open up a lot, and the degree of the gathering of these requirements is also a higher sharpening machine for grinding machines, mainly gathered in Western Europe. Knife machines in Asia and North America. Moreover, within such a large demand range, the demand is more than one billion US dollars. How can we get a share in this mall, which requires the acceleration of the development of the enterprise, more to consider the expansion The knife machine has its own enterprise combat effectiveness and competitiveness. The domestic accessories export is also a very large shopping mall, and domestic accessories have been pushed to the tip of the knife. China's domestic fastener industry structure is very turbulent and does not say that its own organization is very turbulent sharpening machine. And the grinding machine and all products are in a stage without hierarchy. It is important to know that a low production level will result in a lower value for the product itself. And, in this case, the price will become difficult to progress. Nowadays, the financial crisis has sprung around the world. These anti-dumping actions and losses are naturally linked to the instability of the domestic fasteners themselves.   Maintain the method of verifying the drill sharpener When using the drill sharpener, be sure to pay attention to the fastening. The fasteners should connect reliably, especially the sharpening disc, the sharpening of the sharpening disc is indirectly tied to the precision and quality of the tool grinding. Then you need to pay attention to the Micra-10 drill bit grinder transmission components. The smoothness, bite strength, tightness, etc. of these components are all the deviations that form the transmission system, and thus the ideal grinding result is not achieved. For the wearing parts in the transmission mechanism, there must be a lot of spare parts. Generally, the spare parts provided by ordinary manufacturers are quite sufficient. Once the invented parts are damaged, they must be replaced at any time. When the spindle rotates, the sound is very loud. This is caused by the difference in the bearing position. Perhaps the screw against the spindle is loose. When this problem is encountered, the spindle should be changed or the screw should be tightened. If the motor does not turn when the switch is turned over, check the circuit. If the switch is broken, the switch should be replaced. If it is a line problem, the line should be checked. The cause of abnormal noise OF Micra-10 micro drill sharpener Drill bit grinder will inevitably present some problems during the application process. This is a common problem with the machine. This is mainly because when using the machine, some components will be worn away at the moment and then present a series of problems. According to reports, the use of the sharpening machine will show abnormal noise for a long time. What is the reason for this? The first thing that should think of is that its friction is relatively large and the lubricant is lacking. So look for some more joints of activities, check and check to increase the oil. There is also a possibility that the link screw of the sharpener is presented. Loose phenomenon. In this case, we have to check where the looseness is present, and then check if there is any problem with the screw. If this phenomenon exists, screw the screw. The above is the reason for the abnormal sound of the sharpener, and I hope to assist you. Therefore, the machine should inspect frequently. Some parts that are aging should be replaced in time to avoid problems with the sharpening machine and affect the application. Demina is a professional . Our equipment not only has good quality performance, but also the price is relatively affordable. I hope everyone can come and visit.
