To ensure material consistency and stability from the source, we have established a comprehensive quality inspection process that covers the entire production lifecycle—from raw material intake to semi-finished machining, post-heat treatment, and final product shipment.

1. Incoming Material Inspection

• Spectral Analysis: Verifies chemical composition using optical emission spectrometers

• Metallographic Examination: Observes microstructure with metallurgical microscopes

• Initial Hardness Testing: Screens out soft spots or material impurities to ensure baseline mechanical integrity

2. Post-Heat Treatment Performance Validation

• Rockwell Hardness Test: Ensures proper hardness levels (HRC 58–64) are achieved

• Non-Destructive Testing (UT/MPI): Ultrasonic Testing (UT) or Magnetic Particle Inspection (MPI) to detect internal cracks or inclusions

• Dimensional Stability Testing: Confirms deformation remains within specified tolerances after heat processing

3. Wear Resistance and Fatigue Testing (Sampling)

• Simulated Load Life Testing: Evaluates guideway durability under actual load conditions

• Sliding Wear Test: Confirms surface hardening depth and uniformity to ensure long-term wear resistance

Digital Inspection and Closed-Loop Precision Control

  We have established a fully digitalized inspection and traceability system, enabling closed-loop feedback for the machining data of every guideway we produce. This ensures real-time quality control and continuous precision improvement across the entire production line.

• Laser Interferometers: Monitor guideway length deviations in real time with high accuracy

• Coordinate Measuring Machines (CMM): Precisely inspect the positional relationships of critical surfaces

• Surface Roughness Profilometers: Scan the microstructure of the guideway raceway to ensure smooth rolling contact

• QR Code Tracking System at Each Workstation: Links each process step, machine, and operator, enabling full-process traceability and digital archiving of machining precision

Through our “Machining → Inspection → Feedback → Correction” closed-loop control mechanism, we achieve ongoing optimization of guideway precision and reliable high-volume production with consistently high standards.
