With the machinist industry developed, the society developed. And the processing efficiency is an important part in machine industry. So improving the processing efficiency is one of the main topics in modern society. High speed turning and high efficiency is the main direction, but high speed doesn’t equal to high efficiency.
Halnn, as a professional manufacturer of processing cbn inserts offer the reasonable solutions and suitable cutting parameters specific to high hardness materials industry. Halnn has much experience on machining high hardness cast iron, high hardness steel after heat treatment and gray cast iron. Because of the excellent performance, Halnn has a high reputation in the customers. And many manufacturers have become the loyal customers.
Hardened steel has high rate in high hardness hard to machine industry. It is widely used in automotive, mold, bearing industry. In the process, the main problem is that Heat dissipation is not good, the cutting tool is easy to wear with high temperature, the cutting tools will chip when meet interrupted turning condition.
For example: Machining the raceway and the end surface of the slewing bearings
Machine Materials: 42CrMo
Hardness: HRC47~55
Working Allowance: Less than 2mm
They used ceramic insert before, each tip can only machine one work piece, and the working efficiency can’t satisfy the requirements ,it also can not large working allowance machining .The working time cost long and the lifetime is low.
Two problems (1) High hardness workpiece(2) Cutting Tools Problems
Halnn offer the following solutions as follows:
Insert Grade:BN-S200
Cutting Parameters: ap=0.5mm,Fr=0.45mm/r, Vc=110m/min,Ra0.6~1.0
Insert Lifetime: Processing 8 pieces workpiece with 1 tip
Compared Halnn CBN insert and Ceramic insert, Halnn BN-S200 solid cbn insert realized high efficiency machining .Saved the cutting fluid, and improve the working efficiency, so reduce the costs. And the problems which the ceramic insert mentioned have been solved.
Halnn CBN insert also can be used other high hardness cast iron field, we usually use Halnn BN-K1 Solid CBN insert with roughing, working efficiency will be about 7~8 times of ceramic insert .
If meet common gray cast iron ,roughing often use Halnn BN-S30 CBN insert ,working efficiency will be about 15 times than coated carbide insert, and the cutting depth will be 2 times of coated cutting tools ,cutting speed will be 1.5~3 times of coated carbide insert .
All above is simple application case of Halnn CBN insert. Halnn always devote to offering the cutting tools with high efficiency, high quality and environmental. Halnn not only offer the high quality products, but also offer the reasonable solutions for the customers to help them improve the processing efficiency and lower the processing costs.
