What is Precision Grinding?
Precision Grinding is a high-precision machining process that removes tiny material allowances with abrasive grinding wheels. It is applied after turning, milling and other rough machining to achieve tight dimensional tolerances, precise geometric forms and excellent surface finish for metal components.

Frequently Asked Questions
Here you can find answers to frequently asked questions about custom CNC & EDM machining, material options, tolerances, quotation and delivery. Our team is ready to assist with any extra concerns.
Yes. Precision grinding is well suited for components requiring tight dimensional and geometric control. For complex parts, process sequencing, workholding, wheel selection, dressing, and temperature control are carefully managed to maintain consistency.
We can process hardened tool steels, alloy steels, stainless steels, bearing steels, carbide, and other engineering materials. Grinding wheels, coolant, dressing parameters, and cutting conditions are selected according to the material and hardness.
Precision CNC grinding can achieve micron-level dimensional accuracy on suitable components. Actual capability depends on part geometry, size, material, thermal stability, and inspection requirements. Critical tolerances are evaluated directly from the engineering drawing.
Depending on component geometry, we can support CNC surface, cylindrical OD/ID, centerless, and profile grinding. CNC control enables consistent positioning, repeatable grinding parameters, and stable results for complex or tight-tolerance components.
Yes. We support prototype development, low-volume orders, and high-volume production. CNC programming and standardized process parameters allow the process to be scaled while maintaining dimensional consistency and repeatability.
Precision CNC grinding can provide fine surface finishes directly. When additional requirements apply, processes such as polishing, honing, lapping, deburring, cleaning, or specified surface treatments can be incorporated into the manufacturing flow.
MOQ and lead time depend on material, part geometry, tolerance, grinding complexity, quantity, tooling, and inspection requirements. Prototype quantities and recurring production programs can both be accommodated, with delivery schedules confirmed after technical review.
Provide a 2D drawing or 3D model, material grade and hardness, critical dimensions and geometric tolerances, surface-finish requirements, quantity, and inspection specifications. Our engineering team can then assess process feasibility and recommend an efficient CNC grinding solution.
