1, stainless steel grinding characteristics:
(A) grinding force, grinding temperature is high, the machined surface is easy to burn;
   (2) work hardening trend seriously;
   (3) wear debris tend to stick on the wheel, the wheel pore blockage;
   (4) surface grinding scratches appear;
   (5) Workpiece easily deformed.
2, the grinding parameters selection principle:
   (1) The wheel speed vs selection: from the viewpoint of improving grinding wheel cutting, grinding stainless steel forging flange forging flange, the higher should be used wheel speed vs, however, causes the grinding wheel speed is high congestion, but the loss of the cutting ability, and prone to grinding burn and easy to scratch the machined surface, so choose carefully when grinding stainless steel wheel speed. Practice has proved that the stainless steel grinding wheel speed of not more than 25m / s is more appropriate. (2) the workpiece speed vw choice: With the workpiece speed vw wheel speed vs to change the basic principle is vs low, vw is low; vs high, vw also will increase, which could make the cross-sectional area remained without chip unchanged. and a proportional change vs vw, can reduce the grinding scratches. Typically, the speed of the workpiece and the wheel speed selectable from 1/60 to 1/100 range.
  (3) grinding depth ap choice: in grinding stainless steel forging shaft forging shaft, toughness, high ductility of the material, the cutting depth is less than or equal to 0.01mm, the grinding wheel is easy to adhere to clogging prone to phenomena such as burns and scratches. The reason is that the sand has a certain corner radius, when the grinding depth is too small, do not cut into the sand matrix, while the scratch on the surface extrusion, resulting in increased grinding force and grinding heat, easy to adhere to chip clogging wheel , reducing the grinding wheel cutting ability, resulting in surface scratches. Coarse grinding generally take 0.02 ~ 0.05mm, 0.01mm grinding generally take around.
  (4) the choice of feed: Feed amount generally to the grinding wheel width B to calculate. Cylindrical grinding stainless steel, coarse feed rate desirable (1/4 ~ 1/6) B, grinding feed rate desirable (1/8 ~ 1/10) B. Grinding depth is large, whichever is smaller, grinding depth hours whichever is greater. Workpiece rigidity, the feed may be increased. Thin slim type workpiece and grinding the workpiece, in order to prevent deformation, can be large and small feed grinding for grinding depth. Inner circle grinding, rough grinding feed rate desirable (1/3 ~ 1/4) B, grinding feed rate desirable (1/6 ~ 1/8) B. Grinding shallow hole whichever is greater, grinding deep holes whichever is smaller. When the workpiece machining accuracy and inconel X-750 inconel X-750 surface roughness is higher, the amount of feed should be appropriately reduced
