2011 tungsten carbide coal cutters - all types

Introduction:

ZM Drill tool .Coal winning machine and roadheader's bit is a very important component, Its life and cutting efficiency is a direct impact on mining efficiency, Bits scrap's reason in addition to abrade and break, the lost tooth and carbide crack is another two main reasons. After a lot of research and testing, My company at alloy head in resolving the issue of cracking and shedding made significant progress. We product series of igood bit adopt welding technology of low temperature,And take some special method to prevent head off,and a unique heat treatment process,Avoid alloy head because the second time high temperature heating lead to performance drop,While strengthening bit's head and bit's body binding force,Maximize keep carbide head performance, improve bit body's comprehensive mechanical properties,Effectively preventing bit head crack and fall off. This technology has won a national invention patents.

Stable product quality and superior performance are assured with materials of high quality alloy steel, hard alloy and imported auxiliary materials, controlled atmosphere heat-treatment to the whole part, together with a sound quality assurance system.
