Gray cast iron HT250 |
Continuous turning of the outer circle and end face of the intermediate shell of the air compressor. The workpiece is also made of gray cast iron HT250 material, and its hardness is HB210, which is equivalent to about HRC17. It is also a soft material, but the same surface roughness is required to be Ra1.6μm. More Super Hard uses double-sided 2-edge of CNGA CBN inserts to compare with an imported brand CBN tool. Under the same parameters, the service life is basically the same or even slightly higher than that of competitors. The cost-effective advantage of More Super Hard CBN tools is obvious.
