The design of the wafer grinding machine is basically inheriting the work principle of a vertical grinding machine. A diamond grinding wheel is fitted to the air floating spindle. The wafer grinding machine performs vertical grinding on hard and brittle workpieces requiring rigorous surface accuracy and flatness. One evident example is the use of water surface grinding during semi-conductor processes. This process will decide the minimum sizes for wafer sealing and system sealing. In fact, the rigorous requirements for surface flatness and roughness in wafer surface grinding can be achieved only by a specially designed wafer grinding machines.
The machine employs an air floating spindle fitted with a diamond grinding wheel - the water is sucked onto an air floating table.

Lapping and polishing tools made of wood
These tools made from hard and soft wood can be used rotating or linear (in hand-filing machines. Through profiling, these bobs can also be used on
radii or similar.

Lapmaster's lapping/polishing machines, when used with conventional abrasive, diamond superabrasive, or polishing media, can remove stock and finish virtually any solid material to your required specifications.
Our machines are engineered to lap surfaces so flat you can measure them in lightbands. . . surfaces so smooth, it is possible to get leak- proof mating without gasketing. Lapmaster's lapping and polishing machines provide the proper balance between rate of stock removal, finishing and flatness.
We have in-house design facilities, thus being able to offer fully customised machines.
