µ 8800

The µ-8800 is a high-performance small machining center for 800×800 mm pallets. It is equipped with a variety of countermeasures for heat displacement to ensure stable accuracy over long periods of operation, providing the same machining accuracy as a Jig-borer.

µ Series

High Speed, high accuracy Horizontal Machining Centers

Machine construction and countermeasures for heat displacement to ensure high continuous machining accuracy. Temperature controlled traverse axes and high rigidity indexing table provides stable high accuracy machining.

Temperature Compensation

Stable, Continuous Machining Accuracy

Massive machine construction and extremely responsive drive system designed by utilizing the latest technology. Additionally, stable continuous machining accuracy is realized, thanks to a variety of countermeasures for building machine heat:

  • Column and Base Cooling
    To ensure stable machining accuracy, temperature controlled cooling oil circulates through the column and base. Thanks to this system, the temperature of each component is stable to prevent any displacement.
  • Ball-screw Core Cooling
    Temperature controlled cooling oil circulates throguh the cores of X-, Y-, and Z-axes ball screws to ensure stable machining acuracy over extended periods of high speed operation.
  • Scale Feedback System
    A Magnescale system is used to measure the actual positions of the column, spindle head, and table. This system provides high precision positioning over extended periods of operation.
  • Coolant Temperature Control System
    To prevent thermal displacement caused by coolant temperature increase due to heat generated by machining, the coolant chiller unit maintains the coolant temperature to be the same as room temperature.
  • Head Stock Cooling System
    Temperature controlled cooling oil circulates through the spindle and motor housing to ensure minimum spindle heat displacement

Accurate Jig Boring from Both Sides

Performance levels above the norm

The µ series, equipped with a variety of countermeasures for heat displacement, provides positioning accuracy 4 times better than the ISO 10791-4 standard in place. Because of considerable reduction of vibration caused by high speed axes acceleration/deceleration, unsurpassed accuracy stability from temperature regulation, and coupling systems with the taper cone system that ensure high positioning accuracy for the pallet change cycle, the µ series can easily manage any size lot with the ultimate in accuracy performance.
