Specialized grinding machines address tasks beyond the capabilities of general-purpose grinders. Examples include CNC tool grinders for end mills, spline shaft grinders, internal/external bearing ring finishers, and post-heat-treatment spring polishers. Their rigid frames, precision guideways, and wear-compensation systems deliver surface finishes down to Ra 0.1 µm and geometric accuracy within ±0.001 mm.
Modern units feature digital controls, automatic angle adjustment, tool wear sensors, and integration capabilities for automated cells. They are especially valuable in cutting tool manufacturing, where regrinding extends tool life and reduces per-part machining costs.
KNAVI GROUP supplies specialized grinders directly from top Asian manufacturers including SMTCL, DMTG, WEIDA, and KDE. All machines come with full English documentation, up to 2 years of warranty, operator training, and optional on-site commissioning worldwide.
