Overview


DFG8830 is a DISCO grinder for thinning hard, brittle materials. It is suited to grinding sapphire, SiC and similar materials, and its rigid, high-power spindles and large-diameter grinding wheels enable fully automatic grinding of hard, brittle materials that put a heavy load on the process.

With 4 spindles, 5 chuck tables and 1 turntable, each of the four spindles can carry the best wheel for its step, meeting needs ranging from productivity-focused processing to low-damage, high-quality finishing.

It also handles workpieces bonded to support substrates such as glass or ceramics, accepting Φ5 to 8 inch and up to 3.5 mm total thickness. Despite having 4 spindles and 5 chuck tables, its footprint is a compact 3.5 m², and it can hold 4 cassettes at once.
