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
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
Optec M is optical contactless external diameter measurement equipment for cemented carbide drill for printed-wiring boards. It solves the problems of drill voids through contactless measurement equipment. Moreover, optec MA can also measure blade diameter of routers and drills having even/odd number of blades. Furthermore, we can also offer special products with high resolution specifications.
In addition, we also have other peripheral devices for PCB such as ring setting machine and repolishing machine.
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.
