Our HD CNC brand cylindrical and stepped grinding machines form the core of our professional grinding line, established for the manufacture of parts requiring precise dimensions and high surface quality.
With the ability to perform cylindrical, internal/external diameter, and stepped grinding operations in a single setup, we guarantee the dimensional accuracy of rotating parts such as shafts, bushings, and similar components at the micron level.
With this line, we can provide services for the following tasks:
Spindle and shaft grinding: Machine spindles, transmission spindles, gearbox and drive shafts.
Step grinding: Step (gradual) spindles with varying diameters, bearing housing areas.
Bushing and sleeve grinding: Precision grinding of bushings, sleeves, and bearing housings with internal/external diameter accuracy.
Hydraulic-pneumatic components: Piston shafts, cylinder shafts, sealing surfaces.
Molds and custom parts: Precision reference surfaces and ground guide surfaces.
We offer professional cylindrical and stepped grinding services for mass production and revision work on steel, stainless steel, cast iron, and various engineering materials, meeting tolerance, roundness, and surface roughness criteria. Working from technical drawings or samples, we deliver your parts at a quality level ready for assembly.
