Centerless processing of carbide round bars achieving high precision in outer diameter accuracy, roundness, and cylindricity through unique technology for warping and bending.
We accept orders for centerless processing of ultra-hard alloy round bars. Our company uniquely reduces material warping and bending to the utmost limit, achieving high precision in outer diameter accuracy, roundness, and cylindricity. We perform grinding processing using our proprietary technology. 【Processing Range】 ■ 3Φ to 8Φ ■ 40mm to 200mm (we have established processing technology) ■ For sizes over 200mm, we are currently conducting verification tests. 【Features】 ■ High precision processing ■ Capable of handling small quantities and a variety of products ■ Short delivery times ◎ What is centerless processing? It is a method of grinding the outer circumference of cylindrical materials supported by three tools: a blade, an adjustment grinding wheel, and a grinding wheel. Unlike cylindrical grinding, which supports the material at both centers, centerless processing allows for continuous feeding of the material between the grinding wheels, enabling stable high-precision grinding. *For more details, please feel free to contact us.
