Solid Cemented Tungsten Carbide Rods with One Coolant Hole
Applications
For making the drill bits, end-mills, reamers.
Proctuction Process
Powder making → Formula according to usage requirements → Wet grinding → Mixing → Crushing → Drying → Sieving → Addition of forming agent → Re drying → Preparation of mixture after sieving → Pelleting → Pressing → Forming → Low pressure sintering → Forming (blank) → Flaw detection and inspection → Outer circle grinding and precision grinding (blank does not have this process) → Size detection → Packaging → Warehousing
Quality Control
1. All raw materials are tested in terms of density, hardness and TRS and dropped from 1.2m higher place before use
2. Every piece of product goes through in-process and final inspection
3. Every batch of product can be traced
