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

HELL Direct Acting Sliding Shoe System present an updated model of the traditional sliding spindle system. Sliding Spindle，also called sliding shoe, is a kind of machine accessories mounted on electric engraving machines to assist in engraving copper plates.

A diamond stylus also called engraving stylus for the rotogravure industry is a precision tool used in the rotogravure printing process. It is a small, pointed tip made of diamond, which is renowned for its hardness and durability.

Single crystal diamond turning tool 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 such as nickel, copper, optical glass and silicon wafers.

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.
