Halnn is a Chinese national tool brand enterprise integrating CBN tool design, production and technical services. Its CBN tool
program can complete all kinds of parts in the field of high hardness and difficult material processing, such as turning and milling.
Its CBN tool has been widely used in automobiles, mining machinery, power equipment, energy industry, air-conditioning
compressors, aerospace and other industries. For more than 10 years, it has become a leader in hard material cutting tools,
covering high hardness cutting and high speed cutting in China. In most markets in the product sector, long-term partnerships
with most businesses.
Halnn CBN tools are unique in the field of hard turning hard steel, such as gear steel, bearing steel, die steel and other materials
for turning, milling to promote significant efficiency, and production costs have dropped significantly. For example, Halnn CBN tool
BN-H10 grade hard turning Gcr15 bearing steel, compared with a European brand CBN tool single piece cost reduced by 55%.
The specific analysis is as follows:
Problem: a large-scale enterprise processes Gcr15 bearing steel parts all the year round, the workpiece diameter is 195mm, and
the hardness after heat treatment is HRC62. Originally used is a European brand CBN tool, but the tool cost is high, the production
cost is high, then they want to replace CBN tool to reduces production costs.
Solution: Adopt Halnn brazed CBN tool BN-H10 grade, cutting parameters:
Cutting speed(Vc)=60-250m/min,
Feed rate(Fr)=0.05-0.35mm/r,
Cutting depth(ap)≤1mm.
The specific processing information is shown in the following table:
