We produce Hirth Coupling Gear. It reaches indexing accuracy on ±1 second and rise repeatability in line with the needs of industrial machinery field. It can apply 4th axis, dividing plate, turret, aerospace industry, and manipulator, etc. Meanwhile, we have gear-grinding power chucks. It can keep clamping force stable, form chucks into a shape quickly, and decline the consumption of producing time when lathe creates objects.
