Challenge: To grind both sides of composite strips (fiberglass), fully automated at high speed with tight tolerances.


Using Glebar’s DD-7 Double Disc Grinder (one of the smallest on the market), the composite strip material was successfully ground from spool to spool. The machine’s tractor feed extractor and 10” grinding wheels were instrumental in making this happen.

Feed rate: 6 meters per minute | 19 feet per minute

Grind: 25mm strip 2.9 down to 2.42

Material removal: 0.25mm per side 0.010” per side

Tolerance: (+/-0.025mm) +/-0.001”



Double Disc Grinding Machines



The DD-7 is one of the most compact double disc grinding machines on the market. Designed for grinding small diameter components, it accurately controls their length and perpendicularity. The machine is capable of grinding many high-performance parts for a wide range of industries from medical and aerospace to automotive. The DD-7 can be configured in three fixturing modes, depending on the application, the shape of the part, and the degree of automation required.
