correctly.
Also, as part of your safety education, please make sure to familiarize all of your actual operators with the contents of this guideline.
2. Basic Information of Cutting Tool Material
2-1 Technical Terms
Cutting Tool Material: General term of tool materials, such as Cemented Carbide,Coated Carbide, Cermet,Coated Cermet,
Ceramics, CBN and PCD

2-3 Composition , Ti, Al, Si, Ta, B, etc. and in addition to these, metals such as Co, Ni, Cr, Mo
Carbide, Nitride, Carbon-nitride and Oxide with
is incouded for some.
3. Notes for Handling Cutting Tool Material
These cutting tool materials are very hard,but also brittle. Therefore, they may be broken by shock or excessive clamp force.
Carbide base material, in particular, can be very heavy. Handle with care when transferring and storing large size products or
large quantities as heavy load.
Carbide base material has a different rate of thermal expansion from that of metal material.When brazing the cutting tool
material, use the proper temperature to prevent the tool from breaking.
4. Notes for Machining Cutting Tool
The cutting edge is very sharp; wear gloves when handling or installing tools to prevent injury.
When machining, cutting tools may be broken due to shock, excessive tool wear or improper conditions.
Use protective materials such as safe guards, safety eyeglasses, and gloves to prevent injury.
Depending on workpiece material and cutting conditions, sparks or re may occur. Use protective material such as safe
guards, safety eyeglasses and gloves.
When machining, ying chips or metal pieces may be dangerous. Use protective materials such as safe guards and safety
eyeglasses to prevent injury.
