Cubic boron nitride end mill


Cubic boron nitride end mill

Japan Calloy began to develop an end mill made of cubic boron nitride, the material is the hardest cutting material, more than the usual diamond material. Compared with the overall carbide end mill, the end mill is more suitable for high hardening steel metal parts for milling, and the tool life is very long, its use is mainly the company’s equipment can withstand hardened steel Accurate and efficient high-frequency milling.

However, Calloytool Europe is now offering CBN end mills for the European market. The main purpose of its research and development is not only to improve the surface quality of props, but also can increase tool life. In addition, you can increase the spindle feed and speed, in order to reduce the total production time. Compared with the overall carbide end mill, the end mill has better surface quality and longer service life, mainly for high hardness of steel man-made and unmanned (high frequency) cutting, in order to produce mold The There are many types of end mill, diameter accuracy of 0 ~ -3μm, radius accuracy of ± 2μm, diameter from 0.1mm to 6mm range. Calloy Europe can use existing developed production equipment to develop and produce custom end mills according to customer requirements. The following is a description of the end mill.


• Suitable for high hardening steels up to 70 HRC

• Suitable for high speed milling

The main type

•Fine cutting end mill [RG]

•Round edge cutter [STR]

•Shell-shaped round cutter [STR]

•Rough Cut End Milling Cutter [AR]

•Fine cut full R end mill

•Pillier End Milling Cutter [DR]

•Full R finishing knife [AER]

•Pill-head type coarse cutting ball end mill [AR]

High precision

• Radius accuracy: ± 2μm

Features TOWA CBN end mills

• Increase tool life

• Improve surface quality

• Reduce production time

• Reduce the total cost of the tool


drill and tools

The tools series of drills and routers are manufactured on proprietary devices, both internally designed and built. This strategy enables our engineers to “design” the highest level of product quality, using more than 40 years of knowledge and experience. This advantage enables us to install innovative, industry-leading devices such as DIS (automated optical detection systems) and ADP (microdrill automatic drill Pointers) that are much earlier than our competitors. It also ensures that we are able to adapt more quickly to the needs of technology or capabilities, such as the growth of micro drilling, but low levels of investment help keep costs competitive. Through this strategic alliance tool has reached and maintained its first market position.
The high precision linear motion guide is an important part of the micro diameter bit.
The oint tool is the first linear motion guide in Japan. This unique rolling mechanism achieves higher precision and performance than ever before. Since then, we have used these guidelines on the production line, but have also made them available on the market. Our unique guide won a considerable market share. Especially our super – finishing products, whose bearing surfaces are almost mirror finish, are unique. They are often used in applications requiring high accuracy and reliability, such as optical measuring equipment and medical equipment.
Since April 1999, we sponsored Tokyo symphony Orchestra (Tokyo Phil Harmonic Orchestra), the Orchestra is one of Japan’s main Orchestra, purpose is through our contribution, expand the music art promotion activities in Japan, such as the European music art.
Tokyo philharmonic orchestra
In 2011, the Tokyo philharmonic orchestra celebrated its 100th anniversary, becoming Japan’s first symphony orchestra. About 130 musicians, TPO, often perform symphonies and operas. TPO honorary conductor, mei mingchang, has been conducting TPO since 2001. TPO was proud to appoint mikhail prettneff as a special guest conductor and Andrea Battistoni as the main guest conductor.
