Air compressors, as the main equipment for industrial production of air source power, need to have high reliability, high energy efficiency, low noise, high cleanliness and other qualities. Air compressor is widely used in various industrial production fields, and it is also one of the most common parts in  machining industry.

The surface of the air compressor box is plane-milled, and the surface roughness is required to be Ra3.2μm. More Super Hard only installs one CBN milling insert on the milling cutter head with a diameter of D150mm for finishing. It is a non-standard customized SP12 CBN milling insert. The surface effect of the processing can fully meet the customer's standards and requirements. Compared with an imported brand competitor under the same parameters, the tool life is comparable. More Super Hard still has a high cost performance for non-standard customized CBN tools. While maintaining the same processing efficiency, it can reduce the price of the blade and reduce the processing cost of a single piece.

Note: the service life is equal, the cost performance advantage is obvious

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.

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.

Note: the cost performance is higher than the existing imported brand tools
