Solid Carbide End-Mill Manufacturing Process
- Carbide blank selection: The carbide grade, diameter, length and blank condition are matched to the approved tool specification.
- CNC tool grinding: Flutes, end geometry, helix angle, corner radius and cutting edges are produced according to the approved drawing or catalogue specification.
- Edge preparation: Edge honing or preparation is selected according to the workpiece material and machining application.
- Dimensional inspection: Tool diameter, shank size, cutting length, overall length, runout and geometry are inspected according to the agreed quality plan.
- Marking and packaging: Product marking, private-label packaging and batch identification can be provided for approved OEM and distributor programs.
- Final release and export delivery: The final document package, packaging and shipping requirements are confirmed before dispatch.
