Quality Control System
Each CNC machine tool is manufactured under a structured quality control process covering machining, assembly, testing, and final inspection stages.
Incoming Material Inspection (IQC)
Before production begins, all raw materials and components are inspected.
Inspection items include:
●Cast iron structure quality and internal stress condition
●Ball screws and linear guide accuracy grade
●Spindle runout tolerance verification
●Electrical components brand and specification check
Purpose:
Ensure only qualified components enter the production process.
Machining Process Inspection (IPQC)
During machining of machine components
Inspection includes:
Guide rail installation flatness
Screw alignment accuracy
Structural machining tolerance verification
Machined surface quality control
Tools used:
Precision measuring instruments
Dial indicators
Laser alignment tools (for key components)
Machine Assembly Inspection
During assembly stage, each subsystem is checked:
Mechanical assembly:
Bed and column alignment
Axis movement smoothness
Lubrication system installation
Electrical assembly:
Wiring layout verification
Control system installation
Safety interlock testing
Machine Running Test
Each machine is tested continuously before shipment.
Standard test duration
24 to 72 hours depending on machine type
Test content
Continuous axis movement testing
Tool change cycle testing
Spindle load operation test
Thermal stability monitoring
Purpose
To verify stability under real working conditions.
Accuracy Inspection Before Shipment
Final inspection includes:
Inspection results can be recorded and provided upon request.
