The Lapmaster DFL line of dual face lapping machines feature 3 and 4-way, planetary models with sophisticated control systems.

Dual Face Lapping or Polishing Machine

These machines are capable of executing complex lapping routines while producing precise and repeatable results. These units, available with carrier diameters of 4" up to 40", can lap a wide range of materials to very tight specifications. Applications requiring conventional abrasive, diamond superabrasive, and fixed abrasive processes are all easily accommodated through robust construction and use of high quality machine components.

A programmable controller governs machine operation. Custom software prompts the operator for specific operating parameters and stores a number of routines for recall as needed. Through a load cell, the controller continually monitors and adjusts the top plate weight to maintain constant pressure on the parts.

Automatic digital thickness control is obtained through the use of an extremely accurate, centrally-located electronic probe. Each machine is built on a heavy duty, rigid box beam frame. The top plate assembly is supported from a 2 or 4-post bridge for stability and durability. The unique combination of pneumatic controls, stiff frame design, and load control algorithms produce the most accurate and repeatable thickness results in the industry.

Custom lapping plates are available upon request, as are special electrical services. Each machine is custom designed for the specific application, and comes complete with a set of four conditioning gears, a flatness gauge, and a starter kit of consumables.

For high production applications, Lapmaster Wolters offers several options including water cooled machining plates, a pneumatically assisted ring gear mechanism for easy machine loading and unloading, and full automation packages for certain models.
