Speedfam [india], in collaboration with speedfam co ltd of japan, provides offers watch glass polishing machines. Indian homological industry is growing almost about 40% each year and with the need of indigenisation of components, demand for watch parts is growing multifold. Watch crystal is one of the critical component in terms of accuracy as well as for its aesthetics. The wash glass polishing machine can take care of these parameters while keeping the processing cost at its minimal. This watch glass polishing machine is a 4-way double side polishing machinewhich is having plate diameter of 630 mm equipped with cerium based polyurethane pads. These cerium based polyurethane pads along with cerium oxide of purity 70% and average particle size of 1.6 micron is applied inused for polishing of watch crystals. 4-way motion decreases reduces the friction of polishing pad and it also hence reduces wear out of the same to a great extent. The life of pad and carriers is also greatly increased due tobecause of this type of motion, the life of pad and carriers is also greatly increased. Pneumatic pressure control system permits allows precise process pressure on the watch crystals which helps to even out initial thickness variation, removes chipping produced during edging operation and polishes the crystals to the required finish accuracies. Approx 30-35,000 crystals of dia 25 mm can be polished per month on single shift basis.
