Comprehensive Shaft Machining
Concentricity accuracy to 0.01 mm, ensuring stable rotation
We employ an integrated turning and precision grinding process to control concentricity accuracy within 0.01 mm. By ensuring the center of rotation is aligned with the axis, we help you achieve stable motion and reduce the risk of vibration during operation.
Ra 0.8 surface finish, ensuring consistent contact
We precision grind critical areas to achieve a surface finish of Ra 0.8. This process creates specific surface integrity, resulting in reliable sealing and controlled friction, which translates to less heat generation and more stable component performance.
Coordinate Measuring Machine Verification, ensuring reliable assembly
We use coordinate measuring machines (CMM) to measure each axis according to your drawings to verify that all tolerances meet your requirements. This documented precision helps your components be correctly assembled immediately upon arrival, avoiding unexpected delays or rework during production.
Fine surface texture ensures seal integrity
We have precision grinding capabilities to achieve a stable surface roughness of Ra 0.8. By removing the tiny protrusions left by CNC turning, we provide oil seals that perfectly fit the required smooth contact surface, thus preventing potential fluid leaks.
Burn-free edges ensure safe installation
Our professional deburring and polishing processes ensure a smooth and flat surface in every transition area. By eliminating sharp edges that could tear soft seals during installation, we help you ensure a leak-free installation and protect the integrity of the sealing assembly from the outset.
Controlled friction for stable operation
Our double polishing process ensures a uniform surface height across all contact areas. This consistent surface profile reduces heat buildup and unpredictable resistance, resulting in smoother mechanical movement and more stable performance of rotating components.

Tolerance & Fit Capabilities
We specify tolerance class by feature type — not a single blanket number. Bearing journals get tighter control than non-functional diameters. That’s how precision shaft machining should work.
Feature | Standard Tolerance | Achievable |
|---|---|---|
OD — bearing journal | ±0.005 mm | ±0.002 mm |
OD — non-functional | ±0.01 mm | ±0.005 mm |
Length / step location | ±0.01 mm | ±0.005 mm |
Keyway width | JS9 / P9 fit | Custom |
Thread pitch diameter | 6g / 6H class | 4h / 4H class |
Spline — major Ø | ±0.01 mm | ±0.005 mm |
Bore concentricity | ±0.005 mm | ±0.003 mm |
Surface finish — turned | Ra 0.8 μm | Ra 0.4 μm |
Surface finish — honed | Ra 0.4 μm | Ra 0.2 μm |
“Achievable” values require dedicated setup and gauging verification. Discuss during DFM review — we will confirm feasibility before quoting.
