Process Flow

標準製造流程

01

Start Here

Raw Material Inspection & Preparation

Ensure raw materials meet the quality requirements for precision machining.

check Inspect material composition and hardness
check Perform visual defect inspection
check Cut into sizes suitable for machining

02

CNC Precision Machining

High-precision machining is performed using computer numerical control (CNC) equipment.

check Set up programs and tool paths
check Control cutting speed and feed rate
check Machine to near-final design dimensions

03

Grinding & Polishing

Improves component surface finish and dimensional precision.

check Use surface grinders or internal/external cylindrical grinders
check Perform polishing to reduce roughness
check Ensure the surface meets design specifications

04

Heat Treatment & Stress Relief

Improves material properties and reduces machining stress.

check Perform annealing or quenching
check Relieve residual stress to prevent deformation
check Proceed with finishing after cooling

05

Quality Check

Precision Inspection & Measurement

Ensures parts meet design tolerances and quality standards.

check Use a coordinate measuring machine (CMM)
check Surface roughness inspection
check Dimensional and geometric tolerance verification

06

Final Cleaning & Packaging

Completed parts must be kept clean and properly protected.

check Ultrasonic cleaning to remove oil residue
check Rust prevention treatment and drying
check Packaging with batch number and inspection report labeling
