Stone Lapping Unit of Ball Grooves of Linear Rail BSFJ-15 PATENTED

Main Features

  • Installs easily on grinders and other general-purpose machines, capable of high accuracy machining with stability
  • Adoption of parallel linkage creates an oscillation center at a remote point, realizing circular oscillation by using that point as the oscillating center of the workpiece. This eliminates the need for a mechanical axis center the workpiece oscillation center. Arms with large inertia are also not necessary, which increases the flexibility of overall configuration of the unit and on workpiece handling.
  • A rigid parallel linkage mechanism is used, achieving accurate both arc movement and 600 FPM oscillation, which are of the utmost importance when stone lapping, realizing high accuracy and high efficiency
  • Oscillation axis uses direct-drive system powered by an AC servomotor. Oscillation angle, oscillation angle center conversion angle, and oscillation frequency can be easily set using the touch screen. Grindstone pressurization is controlled by an electropneumatic regulator, which also allows the conditions for multi-step rough and finish machining to be set, further improving accuracy and efficiency.
  • Simple attachment/detachment structure of stone head assembly for more efficient stone replacement and changeover
  • Features an auto-slide stone head that enables a 40mm grindstone pressure stroke, making continuous operation for long hours feasible
