The wet milling, also referenced as wet grinding, is a process used to grind and blend slurry (a mixture of power and liquid) by using ball milling technique to achieve a desired particle size distribution.

During this process, the milled slurry is dried and granulated in a spray dryer, achieving the optimal physical and mechanical properties that are required by downstream pressing process.

After spray drying, the RTP (Ready-to-Press) powder is pressed and compacted to a desired shape using a specially designed mold.

After pressurization and compaction, sintering process is carried out to remove binders and alloy the agglomerated powders.

The sintered carbide is then fabricated through centerless grinding process to achieve precise sizes and tolerances of tool blanks.

The grinding of sintered carbide tools is done by double disc grinding machine, which produces smooth finish for cutting tools.

In this process, wet blasting machine is adopted for finishing of surfaces and cutting edges of cutting tools.

Cleaning solutions are used to remove the oxides and stains from the surfaces of cutting tools.

PVD coating process is applied to extend tool life by forming a solid material onto the substrate.

In the CVD coating process, the hard material layers on tool surface are formed in a chemical gas phase process.
