TECHNOLOGY

RAW MATERIAL

High purity and uniform particle size of WC and Co powder can get better quality and stability of mixed material, the microelement of TaC can let cemented carbide get better combination property, it also helps with welding. The aviation gasoline is more pure than regular gasoline with low impurity content. Tilting wet mill is convenient for loading and unloading materials, in order to obtain uniform particle size and fine mixed materials, the maximum ball grinding time can be up to 72 hours.

BLANKS

HIP can make the cemented carbide obtain better internal structure and porosity. It has been proved that the physical and mechanical properties of cemented carbide sintered by HIP are far better than ordinary vacuum sintering.

SEMI-FINISHED

Welding technology is one of the key factors of carbide burr quality, we use sandwich type silver welding material and automatic welding machine with infrared temperature control, control well the welding stress, stability and uniformity, refusing carbide blanks serious oxidation, keeping the steel shank after welding without significant change in hardness.

FINISHED

The third-generation five-axis automatic CNC grinders for carbide burr with better precision control, we control well the angle of the cutting teeth, whole axial run-out, surface perfection and the consistency for each piece of carbide burr.

QUALITY

RAW MATERIAL QC

Each batch of material must pass through the vibrating screen, strictly control the possible uneven particles or impurities, make sure that the particle size of each batch of materials is uniform, to get the fine material everytime.

BLANKS QC

We make sample piece for each batch of raw material, after monitoring and analysis of the sample piece, we obtained various performance parameters of this batch of raw materials, includes its density, hardness, bending strength, porosity, metallographic structure, magnetic saturation, etc., and the corresponding data will be recorded, be numbered and be archived, the retroactive period is 18 months.

SEMI-FINISHED QC

Inspecting the hardness of the steel shank after welding and weld strength, especially in the development of more advanced welding technology, decision based on datas not just speculation.

FINISHED QC

The tooth shape structure and angle of carbide tools will be checked by the quadratic element image measuring instrument, make sure the edge of tooth is sharp without visibly jaggy.

That's where better carbide tools come from, there are no any shortcuts.
