CNC Lathe Parts

In the field of precision manufacturing, the accuracy of CNC lathe parts directly determines product performance. We can stably achieve linear tolerances of ± 0.002mm to ± 0.01mm, and geometric tolerances such as cylindricity, concentricity, and perpendicularity have also reached the forefront of the industry.

We strictly adhere to the ISO 2768 (General Tolerances) and ISO 286 (Tolerances and Fits) specifications. Regarding key dimensions, we use IT6-IT7 grades to ensure high interchangeability between rotating parts and mating components. The following is a typical tolerance level comparison table (structured data, suitable Feature Snippet):

With over 10 years of experience in precision turning, our quality inspection team uses coordinate measuring machines (CMM) and laser scanners to conduct 100% full inspection, ensuring zero defect delivery for each batch of CNC turned parts. We can provide precision guarantees beyond expectations, whether it's complex geometric shapes or small features

CNC turned parts surface finish is a key element that affects the durability, aesthetics, and functionality of parts. We can provide a variety of surface roughness from Ra 0.4 μ m (mirror grade) to Ra 6.3 μ m to meet the stringent requirements of different industries.

Common ways of handling appearance include:

• Fine turning nature: Ra 0.8-3.2 μ m (standard precision machining)
• Polishing/Mirror Polishing: Ra 0.4 μ m or less, suitable for optical or sealed surfaces
• Sandblasting/Pearl Sand: Average matte effect, hiding knife marks, enhancing texture
• Anodizing (Type II/III): specifically designed for aluminum alloys to enhance corrosion resistance and coloring
• Nickel plating/electroplating: stainless steel and brass to enhance hardness and wear resistance
• Other: spraying, passivation, heat treatment, etc

We provide the optimal surface treatment solution based on your functional and appearance requirements to ensure that CNC lathe parts perform well in the usage environment.

Our CNC turning service relies on an internationally leading group of CNC lathe equipment, including high-end models such as the Japanese Mazak Quick Turn series and DMG Mori NTX multi axis compound lathe.

These devices support efficient machining of complex surfaces, small apertures, and thin-walled structures, while ensuring a repeatability accuracy of ± 0.002mm. Whether it's large-scale consumption or high difficulty custom CNC turned parts, our equipment cluster can provide stable and diverse processing quality.

Starting from receiving 2D/3D drawings (supporting formats such as STEP, IGES, DWG, etc.), our engineering team immediately stopped DFM inspection and provided optimization proposals. The process includes: sample making (7-10 days), small batch verification, and mass production entrustment (MOQ sensitive, starting from 10 pieces).

Upload your drawings immediately, and we will provide a free DFM report and quotation within 24 hours!
