304 stainless steel gutter

304 stainless steel gutter parts usually use grinding processing methods to achieve surface quality and processing accuracy requirements. Due to the high toughness, small thermal conductivity and small elastic modulus of 304 stainless steel gutter, the following problems often exist in grinding processing:

1) The grinding wheel is easy to adhere and block;

2) The processed surface is easy to burn;

3) Serious work hardening;

4) The workpiece is easy to deform.

It is not difficult to see that the choice of grinding wheel and grinding fluid directly affects grinding efficiency and machining accuracy. In this paper, the factors affecting adhesion blockage and surface roughness are experimentally studied.

2. Experimental conditions and methods

The specimen material is selected 1Gr18Ni9Ti, and its mechanical properties: σb=530MPa, σ=40%, hardness HB=187. The experiment is carried out on MGB1420 cylindrical grinding machine, the grinding wheel is P400×40×203, the grinding method is cylindrical longitudinal grinding, 304 stainless steel gutter manufacturers in order to improve the reliability of the test results, repeat the test, observe the average effect, eliminate the influence of random factors, while trying to keep the grinding conditions basically unchanged, by changing the particle size, hardness, abrasive of the grinding wheel, replacing the grinding fluid, Grinding dosage to examine the effect on grinding results
