It is very difficult that using common cutting machines the hard and brittle metal.

This paper introduces a new processing think of cutting hard brittle material in a plastic state.

Hard-brittle materials have been popularly used because of their excellent performances.

With the development of science and technology, hard-brittle materials are widely used in comprehensive fields such as optical instrument, electronics, aeronautics and astronautics, instruments and civil industries.

Research on sawing forces during ultrasonic vibration cutting of hard and brittle materials with electroplated diamond wire saw;

The research status at home and abroad about the cutting mechanism, the cutting in plastic region of hard and brittle materials when being sawed and grinded are summarized.

The technology of ELID grinding was successfully applied to super-precision mirror surface grinding of such hard and brittle materials as hard metals, engineering caramics and optical glass.

Numerical simulation on hard and brittle material grinding of complex surfaces parts

The research actualities of the ductile machining for hard and brittle materials are reviewed.

The micro-Ultrasonic machining tests on different hard and brittle materials are carried out.

Study on Erosion Mechanisms and Polishing Technology of Hard-Brittle Materials Machined with Precision Abrasive Waterjet;

It is widely used in machining hard-brittle materials.

Supported by National Natural Science Fund, in this thesis, studies were carried out into grinding technology and morphology simulation studies of belt grinding of hard-brittle materials, aiming at providing a new, economic and efficient machining method for grinding hard-brittle materials.
