Magnetic Grinding and Polishing Machine Parameter Setting Tips and Applications

Author:小编 Time:2024-07-19 Hits:

Magnetic grinding and Polishing machine, as a kind of efficient and precise surface treatment equipment, is widely used in Deburring, polishing, grinding and other processes of various metal and non-metal materials. This paper mainly introduces the parameter setting method of magnetic grinding and polishing machine, as well as the precautions in the actual Application, to provide reference for the operator.

Magnetic Grinding and Polishing Machine Parameter Setting Tips and Applications

I. Introduction

Magnetic grinding and polishing machine utilizes the role of magnetic abrasive in the magnetic field to grind and polish the workpiece. Compared with traditional polishing methods, magnetic grinding and polishing machine has the following advantages: fast processing speed, good polishing effect, easy operation, wide range of Application. In order to give full play to the advantages of magnetic grinding and polishing machine, reasonable setting parameters is essential.

Second, magnetic grinding and polishing machine parameter settings

1. magnetic field strength

Magnetic field strength is the key factor affecting the grinding effect. The higher the magnetic field strength, the greater the grinding strength of the abrasive on the workpiece. But too high a magnetic field strength will lead to abrasive wear faster, reducing the grinding effect. Generally speaking, the magnetic field strength should be adjusted according to the workpiece material, shape and grinding requirements.

Frequency Adjustment: display the frequency of motor work, you can adjust the frequency of motor operation (0-60HZ), can not work for a long time at a low frequency, otherwise it may damage the motor, the parameters have been set up in the factory (only need to adjust the size of the cylindrical frequency) set the parameters privately may affect the normal operation of the equipment. Total time: you can set the time of one cycle of machine work. Forward and reverse time: you can set the cycle time of positive and negative rotation, the general positive and negative setting time should not be less than two minutes, when the work of the start and brake stop down all need time, if you set the rated time is too short will take up the normal grinding time.

2. grinding speed

Grinding speed determines the frequency of contact between the abrasive and the workpiece, which has a significant impact on the grinding effect. Grinding speed is too fast, easy to lead to uneven abrasive wear, affecting the quality of grinding; grinding speed is too slow, it will extend the processing cycle. It is generally recommended that the grinding speed is controlled at 10-30 meters/minute.

3. Grinding time

Grinding time should be adjusted according to the surface roughness of the workpiece, grinding requirements. Generally speaking, the longer the grinding time, the better the polishing effect. However, too long grinding time will lead to serious abrasion of abrasive and reduce the grinding efficiency. In practice, the grinding time can be judged by observing the surface condition of the workpiece to determine whether the grinding time is appropriate.

4. Abrasive selection

Abrasive is an important part of the magnetic grinding and polishing machine, should be based on the workpiece material, shape and grinding requirements to choose the appropriate abrasive. The thicker the magnetic steel needle, the stronger the polishing force, of course, can also be adjusted through the magnetic polishing machine control panel frequency to control the polishing and grinding force, the first time you choose a stainless steel needle, first of all, we must have an understanding of the material of the parts to be processed, for stainless steel and iron and other materials such as hard parts, it is recommended that you choose the stainless steel needle Ø 0.8 or more for the material of the soft copper, Aluminum parts, it is recommended that you choose the stainless steel needle Ø 0.8 or less. For copper and aluminum parts with softer material, it is recommended to choose stainless steel magnetic needle with Ø0.8 or less. In addition, you can also try a few times through the actual to determine the final stainless steel needle model, the aperture of the parts to be processed as well as other crevices, determine the thickness of the steel needle abrasive, generally recommended the use of 5mm-long steel needles for polishing.

Third, the practical application of notes

1. Workpiece placement

Workpiece placement should be uniform, neat, avoid overlapping and extrusion to ensure the grinding effect.

2. Abrasive addition

The amount of abrasive added should not be too much, so as not to affect the distribution of magnetic field. It is generally recommended to add 1%-2% of the volume of the workpiece.

3. Equipment Maintenance

Regularly check all parts of the equipment to ensure the normal operation of the equipment. Clean the abrasive residue in time to prevent clogging of the abrasive.

4. Safe operation

During operation, please make sure to wear protective glasses, masks and other protective equipment to prevent abrasive splash injury.

Fourth, summarize

Magnetic grinding and polishing machine parameter settings have an important impact on the grinding effect. By reasonably adjusting the magnetic field strength, grinding speed, grinding time and abrasive selection, can effectively improve the surface quality of the workpiece. In practical application, the operator needs to be based on the characteristics of the workpiece and production requirements, continue to accumulate experience, optimize the parameter settings, give full play to the advantages of magnetic grinding and polishing machine.
