The ultrasonic-assisted diamond turning tools manufactured by our company are specifically designed for machining hard materials. When installed on an ultrasonic-assisted system, they can directly perform ultra-precision machining on stainless steel without geometric limitations.

Burr cutter, also called scraper, is a precision diamond tool, which is installed on the electric carving machine to remove the copper shavings carved out by the engraving stylus.

Installed on the high-speed machining center, monocrystalline diamond milling cutter is a kind of ultra-precision machining tool, which is mainly used in the processing of non-ferrous metals and non-metallic hard brittle materials.

Ultra-precision diamond turning tools play a pivotal role in the automotive industry, serving as essential solutions for machining high-value components—from injection molds for vehicle camera lenses and LED headlights to aluminum alloy wheels and hard-to-machine carbon fiber composites.

Engraving stylus, also called diamond stylus, engraving needle, engraving knife or carving needle, installed in Engraving machines, is used to engrave text, images or pattern on the copper cylinder.

Single-point diamond turning (SPDT) is now a core process in modern ophthalmic manufacturing, used to produce high-precision contact lenses, intraocular lenses (IOLs), and complex spectacle lenses. To support the strict requirements of this industry—from direct machining of polymers to the production of high-quality molds—we provide a full line
