Paper Abstract
In this paper, a large-scale NC precision face grinding machine is developed. This grinding machine can be used to the
precision machining of brittle materials. The base and the machine body are independent and the whole structure is
configured as a "T" type. The vertical column is seat onto the machine body at the middle center part through a double of
precision lead rails. The grinding wheel is driven with a hydraulic dynamic and static spindle. The worktable is
supported with a novel split thin film throttle hydrostatic lead rails. Each of motion-axis of the grinding machine is
equipped with a Heidenhain absolute linear encoder, and then a closed feedback control system is formed with the
adopted Fanuc 0i-MD NC system. The machine is capable of machining extremely flat surfaces on workpiece up to
800mmx600mm. The maximums load bearing of the work table is 620Kg. Furthermore, the roughness of the machined
surfaces should be smooth (Ra<50nm-100nm), and the form accuracy less than 2μm (±1μm)/200x200mm. After the
assembly and debugging of the surface grinding machine, the worktable surface has been self-ground with 60# grinding
wheel and the form accuracy is 3μm/600mm×800mm. Then the grinding experiment was conduct on a BK7 flat optic
glass element (400mmx250mm) and a ceramic disc (Φ100mm) with 60# grinding wheel, and the measuring results show
the surface roughness and the form accuracy of the optic glass device are 0.07μm and 1.56μm/200x200mm, and these of
the ceramic disc are 0.52μm and 1.28μm respectively.
