Features

  • Its specifications were specially developed for high-speed rotation drilling machine.
  • Especially, with regard to small diameter (diameter is around 100 micron) drills, we use thoroughly tested drills.
  • We have fine-tuned various performance parameters such as accuracy of hole position and wall roughness inside the hole such that we can meet the requirements of users.
  • For achieving processing efficiency and required processing quality, we offer extensive test data as well as technical support.
  • We have extensive line-up of peripheral devices and comprehensive support for preventing breakage issues such as dedicated 200 units package for increasing work efficiency, exclusive repolishing services for small diameter that exponentially reduces the processing cost, and spindle measurement device for maintaining product performance.

Furthermore, function for measuring the number of rotations is also added, and number of rotations of spindle can also be measured. It is an indispensable product in the maintenance of machines.

Pressure & Vacuum Checker PV-CHECKER

Pressure & Vacuum Checker PV-CHECKER

PV-Checker is the measurement device for measuring or observing pressure, suction pressure, and bush contact of pressure foot. It is an indispensable device for managing the operating conditions of the drilling machine itself and managing the product quality for undertaking higher quality drilling work.

Contact Less Drill Diameter Measurement Equipment OPTECH-M/MA

Contact Less Drill Diameter Measurement Equipment OPTECH-M/MA

Carbide End Mills

Carbide End Mills

Union Tool's End Mills were developed from PCB drill manufacturing technology.
The appearance of End Mills resembles PCB drills, but they are able to form various shapes with tip and peripheral cutting edges, whereas drills bore holes only with tip edges.
Metal molds and mechanical parts are shaped with End Mills.

Please see the website of manufacturer for product details.
