Grinding machine that grinds the surface of a workpiece with a lap that is coated or embedded with an abrasive. It is mainly used for grinding high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, thread surfaces and other profiles in workpieces.

Grinding is an important processing method in ultra-precision machining, which has the advantages of high processing precision and wide range of processing materials. However, traditional grinding has the disadvantages of low processing efficiency, high processing cost, processing precision and unstable processing quality, which makes the traditional grinding application limited. Project solution
Grinding and polishing machine

It has eliminated most of the shortcomings of traditional grinding and improved the level of grinding technology. While ensuring the precision of grinding and processing (up to the nanometer level), it also significantly reduces the processing cost, improves the processing efficiency, and further makes the grinding technology practical. It is conducive to the promotion and application of grinding technology, promotes the progress of China's precision processing technology and advanced manufacturing technology, and enhances China's competitive strength in the field of processing and manufacturing, especially for revitalizing the old industrial base in Northeast China.
Advanced processing and manufacturing industries and optoelectronics industries are China's characteristic industries and advantageous industries. They are also China's key development industries. Grinding and processing technologies play an important role in the development of these two industries.
The grinding machine developed by the project team using this new technology is a new high-speed grinding machine. Due to advanced performance, the relevant grinding machine prototype is already in the country.
Grinding machine classification
The main types of grinders are disc grinders, rotary grinders and various special grinders.
Disc grinder
It is divided into single disc and double disc. It is the most common application of double disc grinder.

In the double disc grinder (see [Double Disc Grinder]), multiple workpieces are simultaneously placed in the cage between the upper and lower grinding discs, and the cage and the workpiece are moved parallel by the eccentric or planetary mechanism. . The lower grinding disc rotates, and the upper grinding disc parallel thereto can be rotated or reversely rotated with the lower grinding disc, and can be moved up and down to press the workpiece (pressure adjustable). In addition, the upper grinding disc can be rotated by an angle with the rocker arm about the column to load and unload the workpiece. The double disc grinder is mainly used for processing two parallel faces, one plane (additional accessories for pressing the workpiece), the outer cylindrical surface and the spherical surface (using a grinding disc with a V-shaped groove). When machining the outer cylindrical surface, the workpiece should be properly slid and scrolled. The single-disc grinding machine has only one lower grinding disc for grinding the lower plane of the workpiece, so that the workpieces of different shapes and sizes can be processed in the same plate, and the grinding precision is high. Some grinders also have a mechanism that automatically corrects the grinding disc during the grinding process.
Rotary shaft grinder
The workpiece or the lap (adjustable grinding ring or grinding rod) is rotated by the main shaft rotating in the forward and reverse directions, and the structure is relatively simple, and is used for grinding the inner and outer cylindrical surfaces.
Special grinding machine
There are center hole grinders, steel ball grinders, and gear grinders depending on the workpiece to be polished. In addition, there is a centerless grinding machine that uses a similar centerless grinding principle for grinding cylindrical workpieces.
Three-roll mill
Main uses and performance characteristics:
The three-roll mill is a wet grinding and pulverizing machine widely used in the chemical industry such as paints, coatings, dyes, inks, plastics, leather, rubber, lead, medicine, food, cosmetics and insulating materials. The machine has crushing, dispersing, Emulsifying, homogenizing, coloring, recycling waste and other functions, widely used in scientific research, testing, formulation and crushing micro-commissioning production.
The main components of this machine are three rolls, which are strengthened and protected by Cr12 steel. The wear resistance is up to HRC52°-58°, and the surface hardness can reach 0.2-0.1. The machine is easy to operate, easy to change color, beautiful appearance and noise. Low, price concessions, for research on various materials
Structural components: This machine is mainly composed of (1) body (2) electrical switch (3) discharge plate (4) roll (5) baffle plate (6) adjustment system (7) transmission system (8) motor. A total of eight components.
Working principle: the raw material is added by the natural hopper composed of the middle and the rear two rolls and two baffles. After the opposite and asynchronous rotation of the middle and rear sets, the raw material is turned sharply, shearing and destroying the structural stress surface between the raw material molecules. The pulverization is carried out by the secondary grinding of the high speed in the middle and the front, thereby achieving high-speed uniform mixing of various raw materials.

6, grinding angle to match the performance of various special printing.
7. The grinding machine is equipped with a dust washing device, which can reduce industrial pollution and is beneficial to the health of the staff and the maintenance of the equipment.
8, automatic grinding machine, high-speed grinding machine, precision grinding machine is easy to operate, no professional technology can be operated.

Method of operation
The operator must be familiar with the general structure and performance of the equipment and must not use the equipment beyond its performance. The sum of the part and the grinding product shall not exceed 90% of the volume of the hopper. After the power is turned on, the air is running, and the operation should be smooth and there is no abnormal noise. Otherwise, stop the inspection. Before the workpiece is ground, the workpiece must be degreased and decontaminated. During the processing, the amount of abrasive and the amount of water to be added must be added according to the grinding condition of the workpiece. When the work is finished, stop the power supply, clean the equipment, and do the equipment maintenance work. Safety Operation Procedure Before starting the machine, check the fastening screws and check whether the rotation of the motor shaft is flexible. When the equipment is in operation, it should be stopped when it is found to be abnormal. Every 6 months, the grease fill of the bearing of the vibration motor or rotating shaft should be filled with lithium grease. When you get off work, you should turn off the power.
Empty load test run. The main unit and the analyzer are turning correctly. The main engine empty load test operation is required according to the steering, and its operation time is not less than 1h. When the main engine is running at an empty load, the steel roller should be tightened with the steel wire rope to avoid contact between the grinding roller and the grinding ring. If the condition is unconditional, the grinding roller device can be removed. The main engine air load test should be stable, and the maximum temperature of the lubricating oil should not exceed 800c. The temperature rise must not exceed 400c. The size of the bevel gear of the analyzer should be smooth, no abnormal sound, and ensure the smooth flow of the oil. The blower should observe the direction of rotation. There should be no abnormal sound and vibration. The maximum temperature of the rolling bearing should not exceed 700c, and the temperature rise should not exceed 350c. Comply with the test run. It is proved by the air load test run that the test operation can be carried out only when the components can work normally. Meet the test run time of not less than 8h (hours). The mill should work normally, and the transmission part must not have abnormal sound and shock vibration. The maximum temperature of rolling bearings and lubricating oil does not exceed 800c, and the temperature rise does not exceed 400c. There should be no air leakage in the contact of the flanges in the pipeline installation. Milling output reached the specified target. Adjust the speed of the analyzer so that the finished product size is controlled within the range of 0.44-0.125 mm. After passing the air load and load to make the operation pass, tighten the fastener again and put it into normal operation.
