Precision Grinding Services


Our precision grinding service can achieve a tolerance of 0.005 mm.


We provide Precision Grinding Service since 2013. DH Machining equipped with 3 sets of grinding machines in house which is hand grinding machine, semi-automatic grinding machine and water grinding machine. This enables us process some high tolerancing job in house without any delay.

What is Precision Grinding Service


A grinding machine is a machine that uses a grinding tool to grind the surface of a workpiece. Precision Grinding Services can get very high precision parts. Most of the grinding machines use high-speed rotating grinding wheels, and some of them are using oilstone, abrasive belts and other abrasive tools. Here at DH Machining, we provide high-quality Precision Grinding Services. Whether it is batch production or prototyping job, we got you covered!

A grinding machine can process materials with high hardness, such as hardened steel, hard alloy etc. They can also process brittle materials, such as glass, granite etc. The grinding machine can perform high-precision and small surface roughness grinding, and can also perform highly efficient grinding.

How Grinding Machine Works


The grinding machine consists of a bed with a fixture to guide and hold the workpiece, and a power-driven grinding wheel spinning at the required speed. The speed is determined by the wheel’s diameter and manufacturer’s rating. The grinding head can travel across a fixed work piece, or the work piece can be moved while the grind head stays in a fixed position. Fine control of the grinding head or table position is possible using a vernier calibrated hand wheel, or using the features of numerical controls. Grinding machines remove material from the work piece by abrasion, which can generate substantial amounts of heat.

Advantages of Precision Grinding Services in DH


Surface grinders may be manual or automatic. DH Machining is equipped with both automatic and manual surface grinders so we are able to handle many types of grinding projects using the machine that is best suited for the project.


  • High Precision– Grinding practice is a large and diverse area of manufacturing and toolmaking. It can produce very fine finishes and very accurate dimensions

  • Cost Effective – With our 15+ years experience on grinding machining, we are confident that at least 30% time and cost would be saved, without any compromise on quality.

  • High Surface Quality – Grinding is generally used at the end of a machining process to guarantee the highest degree of precision during the finishing of the workpiece. This is necessary because many classic production technologies, such as turning, do not achieve the required level of precision or leave behind machining marks on the workpieces; which must be removed by grinding.
