Diameter 4.2, depth 12, roughness 0.8, tolerance 0.02., cutting, each edge 0.02. material is stainless steel. Carbide reamers are used, with a 45 degree reamer at the beginning and a crack at the tip! Then change to 30 degrees, the middle of the place or collapse! Either the size is too bad! In the gloom!
We use Okazaki with HSSCO8 reamer. The workpiece material is sus304. Moderate speed. Chlorinated wax cutting fluid.
Oh, I didn't make it clear. The total margin is 0.1. The speed is 300R/min. Feed 40mm/min. Do you mean spiral reamer?
1, use the oil hinge, do not use cutting fluid. 2, down feed, slow down, to be uniform, rhythmic, it is best to play automatic. 3, can not be intermittent, speed slow, 4, reamer material to see if you can change the soft point, as long as the processing can move like.
