Processing hundreds to tens of thousands of holes and shapes in one workpiece is the field we are most good at. Drills and end mills with a diameter of Φ1 mm or less have many achievements. Machining with high speed and high accuracy with Max50000min-1 spindle.



Groove machining with a width of 0.02mm (reference line for laser irradiation), Φ0.05mm / depth 0.04 hole machining (target for laser measuring equipment), Φ0.2mm x 1mm through 10,000 holes (electronic component sorting jig), Please consult us when you need microfabrication such as 0.05mm height unevenness (laser beam focus adjustment jig).



The difficulty with micromachining is that the machining status cannot be confirmed visually during machining. Since it is difficult to judge by cutting sound, many years of experience and equipment for fine machining are required. We have accumulated cutting conditions (feed, rotation speed, etc.) for various materials and shapes.

POINT
  • High speed and high accuracy with Max50000min-1 spindle.
  • Many tens of thousands of holes and shapes have been proven.
  • Hundreds to tens of thousands of holes and shapes in one workpiece are the best field.
  • In particular, drills and end mills with a diameter of Φ0.1 to Φ1mm have many achievements.

Fine processing using ultra-precise high-speed spindle. The spindle in the machining center is not turned, and the motor in the spindle is controlled from the outside. Cutting at ideal machining conditions at a high rotation speed of MAX50000min-1 reduces machining time. It also features low power consumption because it does not use a motor with a large spindle.
