Delivery condition and heat treatment processing of carbon Precision steel tube

Delivery Condition	Heat treatment process
+C	Cold drawn/hard.After the last cold forming,no heat treatment.
+LC	Cold drawn/soft.After the last heat treatment follows the cold drawing there is a light finishing pass. Â
+SR	Cold drawn and stress relieved annealed. After the final cold drawing process the tubes are stress relieved annealed in a controlled atmosphere.
+A	After the final cold drawing process the tubes are stress relieved annealed in a controlled atmosphere.
+N	Normalized. After the last cold drawing process the tubes are annealed in a controlled atmosphere.

Resin Bond Grinding Wheels

Resin Bond diamond and CBN Grinding Wheels are made of either phenolic or polyimide resins. Pressure and heat are utilized to bond the resin to our grinding wheel cores.
Phenolic bonded wheels can be utilized in dry or wet applications. Our polyimide bonded wheels are best utilized in water or oil-based coolants for improved form holding, typically required in CNC tool and cutter applications.

Resin bonded CBN Grinding Wheels are widely used on CNC machine for all tyeps of high speed steel cutter and drills machining and sharpening. They come mostly on shape of straight wheel of plat wheel, or bow shape wheel, or the working part can be sharpened to special shape like v shape or bevel shape.

A silicon carbide stone dresser is mostly used for the diamond or CBN grinding wheels.

Kemei produces all types and shapes diamond grinding wheels and CBN grinding wheels, and wheel dressers. If you need any grinding solution, contact us.
