Model 15 Precision Open-Face Lapping Machine (Legacy)

Compact Design, Precision Performance, and Reliable Flatness Control

The Lapmaster Wolters Model 15 Precision Open-Face Lapping Machine is engineered to deliver consistent surface quality, precise flatness control, and dependable performance in a compact, operator-friendly design. Built with a rigid cast aluminum base and a wrap-around worktable, the Model 15 provides a stable platform while allowing convenient access for workpiece loading, unloading, and handling.

Equipped with three high-density cast iron conditioning rings featuring roller yoke and bearing assemblies, the Model 15 enables effective in-process lap plate flatness control. Its abrasive feed system accommodates both water- and oil-based lapping slurries, supporting consistent abrasive delivery throughout the finishing process.

The machine features a high-torque drive system with a gear reducer, an automatic digital cycle timer, and flexible electrical configurations. With optional variable-speed control, diamond slurry dispensing systems, and specialized lapping or polishing plates, the Model 15 can be tailored to meet a variety of precision surface finishing requirements.
