In order to achieve surface quality and processing accuracy, stainless steel parts are usually ground. Due to the high toughness of the stainless steel, the small thermal conductivity and the small elastic modulus, the following problems often occur in the grinding process:

1) The low price disc for metal is easy to stick and block;

2) The surface is easy to burn;

3) The work hardening phenomenon is serious;

4) The workpiece is easily deformed.

It is not difficult to see that the choice of aluminum abrasive cutting disc and grinding fluid directly affects grinding efficiency and machining accuracy. In this paper, experimental research on factors affecting adhesion clogging and surface roughness is carried out.

Experimental conditions and methods

The material of the test piece is 1Gr18Ni9Ti, and its mechanical properties: σb=530MPa, σ=40%, hardness HB=187. The test piece size diameter φ50mm, length 300mm, φ50 outer surface precision car, the center hole on both ends. The experiment was carried out on the MGB1420 cylindrical grinding machine. The cutting piece was P400×40×203, and the grinding method was longitudinal grinding of the outer circle. In order to improve the reliability of the test results, repeated tests were carried out to observe the average effect and eliminate the influence of random factors. At the same time, try to keep the grinding conditions basically unchanged. By changing the particle size, hardness, abrasive material of the cutting piece, replacing the grinding fluid and the grinding amount, the influence on the grinding effect can be examined.

Analysis of results

The effect of the particle size of the cutting piece on the adhesion rate

The selected white corundum, hardness K, and four cutting pieces with particle sizes of 36, 46, 60, and 80, respectively, the outer diameter of the test piece was longitudinally ground, the grinding length was 600 mm, and the adhesion rate was measured. The finer the cutting piece was. The more serious the adhesion, the looser between the abrasive grains, the chips can be stored in the cavity during grinding; the thinner the cutting piece, the smaller the cavity, the cutting piece quickly loses the chip space and causes blockage.

Effect of cutting piece hardness on adhesion rate

The cutting piece was made of white corundum, particle size 46 and hardness of H, J, K, and L grades. The test piece was ground, the grinding stroke was 600 mm, and the adhesion rate was measured. The higher the hardness of the fiber cutting disc Chinese supplier, the more serious the adhesion. This is due to the low hardness of the cutting piece, the abrasive grain is easily detached from the surface of the cutting piece under the action of the grinding force, forming a new chip space and being not easily blocked.
