What it is

The Lapmaster 15 is a bench-mounted lapping and polishing machine.[4]

The machine is a "ring lapper" configuration, designed to achieve high standards of flatness and surface finish.[4]

The Lapmaster 15 is derived from the Lapmaster 12 and features a scaled-up lapping plate, conditioning rings, and a "wrap-around" worktable.[4]

How it works

Three conditioning rings provide in-process lap plate flatness control, and they locate in yoke/roller bearing assemblies.[4]

Workpieces are placed within carriers or fixtures that run inside the conditioning rings, or large cylindrical parts can be substituted for the rings themselves.[4]

The machine has a rigid, lightweight cast aluminum base.[4]

Standard specifications include a plate diameter of 15 inches (381 mm), three conditioning rings with an inner diameter of 5.5 inches (140 mm), and a standard spindle speed of 60 RPM with a variable speed drive range of 0-60 RPM.[4]

The lapping drive motor is rated at 0.5 HP (0.37 kW), and the polishing drive motor is rated at 0.75 HP (0.56 kW).[4]

The machine measures 25 inches (635 mm) in length, 20 inches (508 mm) in width, and 24 inches (610 mm) in height, with an estimated shipping weight of 285 lbs (129.3 kg).[4]

Where it fits in the process flow

General reference — not yet source-verified

In semiconductor and precision manufacturing, lapping and polishing machines like the Lapmaster 15 are used after initial wafer slicing or grinding to remove surface damage and achieve the required flatness and surface finish.

Applications

The Lapmaster 15 is suited for lapping both low and high production quantities.[4]

Typical components processed include valve bodies, discs, gears, vanes, valve plates, and shaft seals.[4]

In a laboratory setting, it can process a wide variety of materials on an experimental basis.[4]
