A comprehensive review of common knowledge about double end grinders

Due to its high precision and high production efficiency, double-end grinding machines are widely used in many industries such as automobiles and motorcycles, bearings, magnetic materials, etc., such as piston pins, piston rings, valve gaskets, connecting rods, and crosses in the automobile and motorcycle industries. Products of various materials such as shafts, valve plates, shift forks, hydraulic pump blades, rotors, stators, compressor slides, bearing rings and rollers, magnetic rings, magnetic steel sheets, graphite sheets, etc. are suitable for processing.

The double-end grinder is an effective surface processing machine tool. According to the characteristics of the bearing ring, Chinese researchers have developed a special double-end grinder for grinding bearings. However, the grinding machines of various consumer manufacturers have different structures and have their own characteristics. At this time , double-end grinders have developed rapidly in the bearing industry. In the 1990s, China's economic development entered the fast lane and high-precision CNC operating system grinders were developed.

The original double-sided grinder has been improved in type and processing accuracy. Product Overview Editor Entering this century, with the rapid development of China's machinery industry, many imported parts have been developed and replaced by China's own production, such as oil pump blades and compressors. High-precision automotive parts such as sliders can also be widely used in double-sided grinder processing.

Horizontal end face grinders related to lathes and milling machines adopted CNC systems relatively late due to their special requirements for CNC systems. In recent years, with the help of CNC technology, continuous dressing, automatic compensation, and automatic communication of workpieces have been completed on double end face grinders. Grinding wheels, multiple worktables, automatic conveying and clamping and other operating functions, CNC technology is also gradually improving on surface double-sided grinders and internal double-sided grinders.

Horizontal double end grinder applications:

1. Check whether the oil level in the oil pool and tank reaches the hydraulic index.

2. Check whether the brand and material of the oil meet the requirements of the application statement.

3. Each operating handle should be placed in the closed or unloading position. As for the grinding stand in the backward position, the moving parts should not collide with each other.

4. Check whether the motor of the oil pump can operate normally, and then check whether the pressure of the oil circuit, auxiliary oil circuit, and unobstructed oil circuit can meet the requirements of the application declaration.

5. The machine tool should open the air valve, discharge the air in the cylinder and system, and then close the bleed valve.

6. For machine tools with hydraulic operating boxes, the on-off valve and speed handle of the workbench must be adjusted according to the provisions of the operation manual to make the workbench slow and run back and forth several times in a short interval. After the machine tool operates normally, it will gradually adjust to Higher speed, and check whether the operation and reversal are normal, and whether there is any impact or obvious stagnation throughout the process.

7. After the horizontal double-end grinder workbench is running normally, stop the rapid advance, retreat and feed experiments of the grinding wheel frame, check whether there is any impact when the grinding wheel frame quickly moves to the end position, adjust the feed amount within the scope of the application instructions, and check is the action normal.
