What Is a Grinding Machine?

A grinder (grinding machine) is a machine tool that uses a grinding tool to grind the surface of a workpiece. Most of the grinding machines use high-speed rotating grinding wheels for grinding, and a few use oilstone, abrasive belts and other abrasive tools and free abrasives, such as honing machines, ultra-finishing machines, abrasive belt grinding machines, grinders, and polishing. Machine and so on.

Grinders can process harder materials such as

Supply and demand is a prerequisite for the rapid development of an industry. The market demand is great, but the supply side is slightly insufficient, especially with core intellectual property rights, not many companies with excellent product quality, and the industry as a whole lacks brand effects. In the stage of strong demand, the industry has huge demand and good development prospects, which is beyond doubt. However, how to maintain the healthy, stable and sustainable development of the industry requires the joint efforts of enterprises in the industry, especially the spirit of excellence in research and development, to further improve the production process, reduce costs, truly solve the practical difficulties of customers, strictly control the quality, and provide the most Reliable products. ^[1]

Grinding machines and wheels for standard machining

With the increase in the number of high-precision, high-hardness mechanical parts, and the development of precision casting and precision forging processes, grinding machines

According to the motion characteristics and process requirements of the grinder, the following requirements are imposed on electric drag and control: 1. The rotary motion of the grinding wheel generally does not require speed regulation, and it can be dragged by a three-phase asynchronous motor, and only requires one-way rotation. For larger capacity, Y-delta step-down can be used to start. 2. In order to ensure the processing accuracy, make it run smoothly, and ensure that the inertia of the table is small and no impact when reciprocating, the hydraulic transmission is used to realize the table reciprocating and the wheel box lateral feed. ^[1]

In the 1830s, in order to adapt to the hardened processing of parts such as clocks, bicycles, sewing machines and firearms, the United Kingdom

Grinding is widely used and is one of the main methods for precision machining of machine parts. However, due to the high rotation speed of the grinding wheel, the grinding wheel is relatively hard, brittle, and cannot withstand heavy impacts. Accidental improper operation will cause very serious consequences. Therefore, the safety and technical work of grinding processing is particularly important. Reliable safety protection devices must be adopted, and the operation must be focused and ensured. 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 appropriate protective measures should also be taken. When grinding, you should pay attention to the following safety technical issues. Before driving, a comprehensive inspection of the machine tool should be carried out carefully, including inspection of operating mechanisms, electrical equipment and magnetic chucks. Lubricate after inspection, test run after lubrication, make sure everything is good before use. Pay attention to the clamping and clamping when mounting the workpiece. The loosening of the workpiece during the grinding process will cause serious consequences such as flying out of the workpiece and hurting the person or breaking the grinding wheel. When starting work, use the manual adjustment method to make the grinding wheel close to the workpiece slowly, and the starting feed amount should be small. Do not use too much force to prevent collision with the grinding wheel. When it is necessary to control the reciprocating movement of the table with the iron stopper, it is necessary to accurately adjust it according to the grinding length of the workpiece and tighten the iron stopper tightly. When replacing the grinding wheel, it must be visually inspected to see if there is any trauma, and then hit with a wooden hammer or stick. It is required that the sound is clear and without cracks. When installing the grinding wheel, it must be assembled in accordance with the prescribed methods and requirements, installed after static balance commissioning, and commissioned. Only after everything is normal, can it be used. Workers should wear protective glasses during work, and balance the wheel to prevent impact. Measuring the workpiece, adjusting or wiping the machine should be performed after the machine is stopped. When using a magnetic chuck, the surface of the disk, the workpiece should be cleaned, tight, and sucked tightly. If necessary, a stopper can be added to prevent the workpiece from shifting or flying out. Attention should be paid to the installation of the grinding wheel protective cover or the machine tool baffle. ^[2]
