The Application of Halnn CBN inserts in Air-conditioning compressor industry

With the development of the modern technology, more and more manufacturers will pay more attention on the working efficiency and the quality .So how to improve the working efficiency become an important problem.

In order to realize processing with high efficiency ,it need CNC Lathe ,Process Technology . For Lathe, more and more suppliers will use CNC Lathe to realize high speed turning ;For Process Technology ,every manufacturers will have their own technology to improve their processing efficiency; For Cutting Tools ,as the most important cutting tools for cut the working allowance to make sure the roughness and the dimension ,the cutting tools is the key sector for realize machining with high efficiency.

The air conditioning ect. For wework piece materials mainly work piece will affect the working efficiency. ,phenomenon ,which it will appear wear 350m/min,or the cutting speed can no more than insert ,but cast iron gray upper-bearing ,cylinder, include iron ,which cast gray use traditional carbide is compressor can
With the appearance of the cubic boron nitride ,it realize high efficiency turning .The hardness of the cbn insert can arrive HRC95~100, so it has excellent wear resistance, but it has big brittleness. So how to improve the toughness of cbn inserts become the most important problem.

In order to improve the toughness of cbn cutting tools materials ,more and more cutting tools manufacturers begin to research new cbn materials.Halnn is the lead brand of cbn inserts ,first researched BN-S20 Solid CBN insert which can be used for heavy interrupted turning and BN-K1 CBN insert which used for interrupted roughing high hardness cast iron with large working allowance.

Specific to air-conditional compressor industry, Halnn research new cbn insert materials BNK30 and BN-K20 which can realize processing with high efficiency. Both of them belong to welded cbn insert ,it has more cutting edge and will be more economic ,and has excellent wear resistance .The cutting speed can arrive 1500m/min .Compared with imported pcbn inserts ,Halnn cbn insert has better performance.
The following is the application case of cbn inserts BNK30 and BN-K20 machining air-conditional compressor parts
(1) Halnn CBN insert BNK30 processing air-conditional compressor upper-bearing
Workpiece Materials

(2) Halnn CBN insert BN-K20 processing the cylinder of air-conditional application

Halnn BN-K1 Grade CBN Insert---the Best Cutting Tools for machining Cast iron

Halnn BN-K1 CBN insert is one cutting tools which are widely used in cast iron industry, belong to patent product. Halnn use non-metal adhesive ,not only have high processing efficiency on heavy cutting ,but also make sure long lifetime with high stability.

BN-K1 cbn insert use the indexable holder, so it only need turn when change the tips, doesn’t need re-infeed and avoid the cutting marks.
High content Cubic Boron Nitride, Special adhesive and high efficiency cutting tools ability will make sure improve machining efficiency in the process.

Halnn BN-K1 Grade CBN insert compared other brand cutting tools ,with 2 times of the cutting speed ,Halnn BN-K1 CBN insert will machine workpiece about 8 times of other brand .And Halnn has all ISO insert which suit for processing high hardness casting .

The advantages of Halnn BN-K1 CBN insert:(1) Safe Processing
a. The content of CBN arrive 90%, which will reduce the wearness , realize castings processing stability.
b. Halnn non-metal adhesive ,which has excellent Anti-fracture performance, which realize stable cutting tools lifetime
c. Halnn has all ISO standard insert model ,more cutting edge ,reduce the insert costs .
(2) Easily Installation and Removal
a. The holder is indexable holder ,we only need tighten the screws.
b. Change the insert easily: we only need turn to other tips , don’t need re-control the insert, avoid the cutting tools marks.
(3) Heavy Cutting ,High Speed Turning
a. BN-K1 can make sure the roughness with high precision
b. It has more cutting edge, and we can make customerized one .
Compared Halnn BN-K1 CBN insert and with other brand insert
