Tight quality control
In Pinsi, the birth of each set of linear guides and ball screws is an extreme pursuit of “zero defects”.
We take the precision testing process as the core, from nano-scale surface finish to micron-scale motion accuracy, from 100 hours of dynamic simulation to millions of life verification, relying on three coordinate measuring instrument, laser interferometer, material metallographic analysis and other cutting-edge equipment, to build a full-dimensional quality control system. Choosing us means choosing absolute control of quality.
1. Appearance and size inspection
Inspection items:
Surface quality: check the surface of the guide rail for scratches, rust, burrs.
Key dimensions: width, height, spacing of mounting holes (using digital calipers, CMM).
Parallelism/Perpendicularity: Laser interferometer to measure the straightness error of the whole length of the guideway (≤0.005mm/m).
2. Motion performance test
Testing items:
Sliding resistance: After installing the slider, test the no-load push and pull force with a tensiometer (need to comply with the nominal value ±10%).
Repeat positioning accuracy: laser interferometer test slider round-trip positioning deviation (such as ± 0.003mm).
Load rigidity: Apply rated load (e.g. 2000N) and measure the deformation with displacement sensor (≤0.01mm).
3.Quality and Reliability
All products of Pins Machinery are directly supplied by the original factory and support anti-counterfeiting traceability to ensure that every product purchased by the customer is 100% genuine, and the quality is completely synchronized with the original factory standards.

1. Foundation accuracy testing
Detection items:
Lead error: laser interferometer to measure the cumulative error of the full travel of the silk rod (e.g. C5 level accuracy ≤ 0.023mm/300mm).
Axial clearance: fixed nut, micrometer to measure the axial runout of the screw rotating in forward and reverse direction (≤ 0.01mm).
2. Dynamic performance test
Testing items:
Transmission efficiency: ratio of input torque to output thrust (≥90% is qualified).
Temperature rise test: infrared thermometer detects the temperature rise of the nut after 1 hour of high-speed operation (≤ 45 ℃).
Noise test: Measure the noise value under rated speed in the muffler room (≤65dB).
3. Material and process verification
Testing items:
Surface hardness: Rockwell hardness tester to detect the hardness of screw threads (HRC58-62).
Metallographic organization: take samples to observe the metallographic structure of the material after heat treatment (need to be free of cracks and decarburization layer).
