Custom Precision Shafts CNC Machining Service | High Strict Tolerance Shafts

MOQ: 1 Pieces
Delivery time: 20 Day
Micron Ultra Precision Strict tolerance down to ±0.002mm, TIR concentricity controlled strictly; surface finish up to Ra0.2 after cylindrical grinding, zero runout for transmission shafts. Excellent Batch Consistency Multi-axis CNC one-time clamping, eliminate repeated positioning errors. Every shaft keeps identical dimensions in small prototypes & mass orders. Complex Feature One-Step Machining Integrated processing for keyways, splines, threads, stepped diameters and undercuts, no secondary re-clamping, guarantee high coaxiality. Full Material Compatibility
Product Details
We specialize in custom CNC turned & ground precision shafts for hydraulic equipment, automation machinery, motors and gearboxes.
 
Our multi-axis CNC lathes and cylindrical grinders deliver ultra-tight dimensional tolerance up to ±0.002mm, with concentricity and straightness strictly controlled. After fine grinding and polishing, surface roughness reaches Ra0.2, effectively reducing friction and prolonging service life.
All complex structures including step diameters, key slots, splines, external threads and positioning holes are finished in a single setup. We avoid repeated clamping deviation to ensure high geometric accuracy of each shaft.
 
We process alloy steel, stainless steel and carbon steel with complete post-processing: quenching, tempering, hardening, chrome plating and black oxidation to improve wear resistance and corrosion resistance.
As an ISO9001 certified manufacturer, we conduct full dimensional testing for all finished goods and provide formal inspection reports. We accept both small-batch prototype orders and large-volume mass production, offering stable quality and competitive lead times for global buyers.
 
All stepped diameters, radial through holes, angular chamfers, pin holes and spline tooth features are finished in a single clamping setup, eliminating positioning errors and ensuring ultra-high concentricity and parallelism.
 
Suitable for hydraulic jam & valve core components, this shaft features tight fit interference tolerance, low runout and excellent surface finish, which greatly improves the stability and service life of hydraulic systems. Supporting prototype trial orders and mass batch production with full dimensional inspection reports.
