| MODEL LLCD-SERIES PRECISION OSCILLATING HEAD POLISHING MACHINE | ||||
| | ||||
| O To complement our extensive range of Single and dual face lapping and polishing machines Lapmaster has introduced a new line of precision oscillating head polishing machines. O Designated the LLCD series they are, primarily, Microprocessor controlled pad polishing machines specially designed for processing large area glass substrates, they can however also be used as lapping machines. O A self aligning swing arm assembly positioned above the polishing surface is mounted to a swivel head work piece pressure plate.Work pieces of varying geometries can be retained by surface tension or vacuum to the pressure plate. O The pressure plate is designed to swive up from the horizontal working position to just past vertical to facilitate work piece loading and unloading. | ||||

| once via an oscillating carrier between two rotating plates. O The machine consists of a heavy-duty base which houses both the polishing plate and the swing arm drive systems. O The Polishing plate has a polishing pad (type dependent on material to be processed] bonded directly to its upper surface. O Polishing compound is supplied to the centre of the Top or Bottom or both polishing plates via a re-circulatory pumped system.Water can also be supplied to the same de tination on demand. O The work piece pressure plate, which is positioned above the polishing plate, is attached to the swing arm via a selfaligning bearing. O Both the stroke and radius of the swing arm are adjustable. This unique combination of rotating plate and oscillating work piece movement ensures: Maximum utilization of the polishing surface. Suppression and elimination of "tracking" effects on the polishing surface. Improved control of polishing surface flatness. Precise optical flatness control of work piece. O The LLCD series of machines ability to be set up for use as a lapping or polishing means they can be used for processing large Piano optics including: Calcium Fluoride Fused Silica BK7 Quartz Zerodur | ||||
