The tooth shape can be customerized and designed according to the rock strata conditions or the requirement of the customers.
It is possible to be replaced by cutters imported from Wirth, Herrenknecht, Mitsubishi, Komatsu and NFM etc.
The products are manuactured with rigorous design, rationally selected material and advanced technology.
We can supply accessories and repair parts for disc cutter from different factories.
We can repair hobs and replace TIMKEN bearings, cutters and sealing for customers.
The hard alloy are of high impact wear resistance. They are imported or purchased from reliable Chinese brands. The main brands are showb in the following table.
The cutter is made by high-performance air-quenching alloy steel with HRC40-50.
The key position of the cutter surface will be welded with 3-5mm wear-resisting layer.
The hard alloy and the cutter will be joint with medium or high-frequency brazing or inlaying
technology. The silver-base or copper-base alloy is used as welding flux.
We provide interchangeable scrapers and tooth cutter for the shield machine cutters of Herrenknecht, Mitsubishi, Komatsu, NFM and LOVAT etc.
Customerized tooth cutters, tearing cutters and scrapers can be made to meet the requirement
of the customers or according to the strate conditions.
