How many grinding needles does the magnetic grinder need?

The number of steel needles used in magnetic lapping machines depends on the specific polishing needs and workpiece size. Generally speaking, the more the number of steel needles, the better the polishing effect, but also be careful not to overfill the needle resulting in unstable operation of the equipment. According to the manufacturer’s suggestions and the actual needs of users, the number of steel needles in general is between thousands to tens of thousands. It is recommended to select different sizes of steel needles according to different workpiece shapes and sizes when using magnetic lapping machine, and replace the steel needles regularly to maintain the polishing effect and the normal operation of the equipment.

Grinding steel needle
The number of steel needles used in magnetic lapping machines is determined according to the type and specifications of the equipment. Generally speaking, the larger the size of the magnetic grinder, the more steel needles are required.

Some small magnetic lapping machines usually use thousands to tens of thousands of steel needles, while large magnetic lapping machines may use hundreds of thousands or more. In addition, the diameter and length of steel will also affect the use of the number of, in general, the smaller the diameter of the steel needle, the shorter the length, the number will increase accordingly.

When selecting the number of steel needles, it is also necessary to consider the size and shape of the workpiece and the requirements of polishing effect. For some complex workpieces, more steel needles are needed to ensure the polishing effect. At the same time, in order to avoid the unstable operation of the equipment caused by overloading, appropriate amount of steel needle should be selected according to the recommendations of the equipment.

In addition, in order to ensure the effective operation of the polishing effect and equipment, and suggest to replace steel needle on a regular basis. The specific replacement cycle needs to be determined according to the actual use. It is usually recommended to replace every few months or every certain number of polished workpiece.

The number of steel needles used in magnetic lapping machines is related to the specific polishing requirements and workpiece size. The following aspects need to be considered when selecting the number of steel needles:

1. Shape and size of the workpiece: Different shapes and sizes of the workpiece need different numbers and specifications of steel needles for polishing. Usually, the larger the workpiece, the more needles are needed.

Two, polishing quality: want to achieve better polishing effect, need to use more number of steel needles, in order to cover the workpiece surface more evenly. But too much steel needle to cause a decline in the polishing efficiency, may also influence the stability of the equipment.

Three, equipment capacity: magnetic grinding machine equipment capacity is also one of the factors to choose the number of steel needle. The larger the capacity of the device, the more pins can be accommodated.

In practical use, the appropriate number of steel needles is generally determined according to equipment capacity, workpiece size and polishing quality. Generally, the number of steel needles used in magnetic grinders ranges from thousands to tens of thousands. At the same time, it is also necessary to note that the wear of the steel needle should be checked regularly during use and replaced in time to ensure the polishing effect and the normal operation of the equipment.
