Double Sided Lapping & Polishing Machines for Precise Control

• Computerized programming - 28 different 14-step recipes handle any application.
• Precision Removal System for Symmetrical or *Asymmetrical material removal.
• Three independent velocity servomotor drives for quiet, smooth operation.
• Accurate lap force control - run as low as 8 pounds (3.6 Kg) on fragile parts.
• Automatic plate flattening through processor-controlled speed modes.
• Soft start, soft stop and load ramping control gently handles fragile parts.
• Retractable ring gear eases the lift-off of thin, hard to handle parts.
• Multi-step programming "tops off" thicker parts at lighter pressure for less thickness variation between individual parts.
• Sealed membrane keypad and four-line back lit LCD operator interface is rugged, safe and slurry-resistant.

Precise Pressure Control

• Precision servomotor drive coupled with ball-screw obsoletes air cylinders for top plate support and lap force control.
• Programmable transition point from fast down to float down for parts of different thickness.
• At end of run, servomotor drive controls vertical travel of top plate to zero load WITHOUT lifting off parts, keeping parts in their workholes.

3-Way Motion - Key to Precision

• Bottom lap plate is fixed - providing a zero-runout base.
• Carriers orbit the center sun gear at controlled speeds.
• Top lap plate spins at twice the speed of the planet carrier orbit speed.
• Removes material from top & bottom of parts equally.   * See Footnote below for Asymmetrical (unequal) material removal.
• Minimizes contact stresses on part edge and carrier teeth, which reduces "crashes" and edge chipping, and increases carrier, ring and center gear life. For very thin parts and high loads.
