Product Description

Super Precision Turning Capability

Sanluo Precision's super precision turning features: machining material (brass, aluminum alloy, stainless steel, titanium alloy, copper alloy, engineering plastic, ceramic, sapphire); machining size (minimum diameter φ0.1mm, maximum diameter φ500mm, maximum length 2000mm); surface quality (Ra0.01-0.8μm, mirror finish Ra0.01-0.05μm); thread machining (micro thread pitch 0.05mm, precision thread grade 2-4 grade); groove machining (minimum groove width 0.05mm, depth tolerance ±0.001mm). Process advantages: ultra-low cutting force (avoid workpiece deformation), high-speed precision turning (efficiency increased by 2-3 times), dry cutting (environmental protection, no pollution).

Quality Control and Application

As a professional manufacturer of super precision turning, Sanluo Precision implements strict quality control: 100% inspection of key dimensions by CMM, roundness meter, roughness meter; SPC statistical process control, CPK≥2.0; tool precision management (diamond tool tip radius 0.01-0.1mm, wear compensation ±0.0001mm). Application cases: automotive (fuel injector needle valve IT3 grade ±0.0005mm, surface Ra0.02μm), aerospace (turbine shaft roundness 0.0003mm, coaxiality 0.0005mm), medical (stent tube wall thickness tolerance ±0.001mm, surface Ra0.01μm), precision instrument (micrometer spindle thread grade 2 grade, pitch error ±0.0002mm). We have provided customized high precision machining services to Bosch, Delphi, Medtronic, Siemens and other enterprises, with an annual output of 500,000 pieces and a qualification rate of 99.9%.
