Grinding after machining process, instead of using ground material

Updated: Jun 2

Some products such as shafts and pistons that require precision tolerances in surface roughness and cylindricity.


In some cases ground materials are required to be used on the drawing, however the ground material itself is 20 to 30% expensive than non-ground material, which significantly increases the overall production cost, especially for large lot orders.


Applying centerless grinding process after machining with non-ground material can achieve high-precision finishing and high surface roughness that could reduce product costs.


We, E&H Precision has more than 50 centerless grinding machines as well as cylindrical grinding machines and flat grinding machines in Thailand & India.
