Gray cast iron HT250 |
Horizontal machining center of air compressor box for boring the inner hole of intermittent processing, the material is gray cast iron HT250, its hardness HV250, equivalent to HRC22 or so, belongs to the soft material, but the processing requirements of surface roughness to Ra 1.6μm. More Super Hard uses T-shaped CBN inserts, which are compared with CBN inserts of an imported brand. Under the same conditions of parameters, the tool life reaches the value of competitors, the processed surface quality is excellent, and the roughness also meets the requirements. Finally, the replacement is carried out with cost-effective advantages.
