How We Handle Your CNC Machining Project

Machining Workflow
01

Drawing Review

Review 3D CAD, 2D drawings, tolerance notes, material and surface finish requirements.

02

Machining Strategy

Select CNC milling, turning, 5-axis machining or combined operations according to geometry.

03

CNC Production

Machine parts according to material, size, tolerance and quantity requirements.

04

Inspection and Finishing

Check key dimensions, surface quality, threads, holes and finishing before shipment.

Quality Checks for CNC Machining Parts

Quality control should be planned before machining, not only after production. Hongrui checks key dimensions, hole positions, threads, edges, surface quality, critical tolerances and assembly interfaces according to drawings and project requirements.
