Halnn CBN inserts machining air-conditioning compressor comp

As the development of the modern society, air conditioner almost becomes family’s, factory’s and enterprise’s necessary electrical appliance. With the rising numbers of air-conditioners, the manufacturers of air conditional compressor, also increased.

Air conditional compressor’s main compound contains cylinder, crankshaft, bearing, cylinder head, main materials are gray cast iron and ductile iron, and main processing technology is cast molding. For example: cylinder use HT250(German-GG25;America-No40B),it can’t have air hole, sand hole and shrinkage after casting molding.

How to machine the main compound of the air conditioning compressor?
Machining air conditional compressor compound require high efficiency and good quality. How can the manufacturers improve the efficiency and at the same time make sure good quality? Halnn Tools is one manufacturer of producing cbn insert. And we often contact with our consumers directly, so we are very familiar with air conditional compress components.

Now we will introduce that Halnn offered what cutting tool materials and practical parameters for the machine manufacturers. Because our customers information are confid

ential, so we will called them as company A and Company B.

2. Halnn Superhard material machining air-conditional compressor components air cylinder
Company B:
Machining component: air conditional compressor air cylinder
Material: HT200 (German-GG20,America-No35B)
Hardness: HB170~210
Allowance: about 3mmMachining tools materials: coated carbride
Each cutting edge machining little workpiece, all these lead to cutting tools high cost. and we select BN-S30 Solid CBN inserts for them after analysis their products. Halnn BN-S30 is solid CBN insert, mainly researched for large allowance rough turning cast iron and ductile iron, also can be used for semi-finish and finish turning process. For example, it can be finished if the allowance is less than 2mm. Halnn BN-S30 Solid CBN inserts machining air conditional compressor components air cylinder parameters: ap=2mm,Fc=0.2mm/r,Vc=400/min.

Machining efficiency: Comparing with coated carbide tools: Each cutting edge lifetime is 4 times than coated carbide tools based on 1.5 times cutting speed of coated carbide tools. Halnn BN-S30 grade CBN insert has 8 cutting edges, that is to mean total inserts life time can be more than 32 times than coated carbide tools.
