[INQ. NO. 2606E19] DTR Co. is consistently expanding its high-quality products, new technologies, total services, and eco-friendly businesses in order to lead change and innovation, and for responding to customers’ needs.

Master Gears
DTR’s Master Gear is the precision tool used to confirm gear accuracy in the automobile and aerospace industries. The master gear is normally used to check gears according to the high quality required in a transmission plant.
The classes of the gears are M1, MO, and MOO, respectively, and they are generally produced by the specifications of DIN 4 [JIS 0]. The master gear can be produced with special designs as customized specifications are used.
It is also possible to make it with lead crowning and profile crowning. Depending on the jig of the master indicator, normally one teeth taper and straight bore is used. Master gears can be affected by increased abrasion, and corrosion resistance by PVD coating.

Broach Cutter
A broach cutter is the cutting tool machining continuously cleaning the internal surface or external surface of the workpiece by several roughing & finishing teeth. It achieves high-precision machining through shorter work time.
Complex machining surfaces are possible as the axes coincide. Skilled labor is not needed for machining, as various conditions like cutting depth per teeth and total cutting depth are set in design & production. Superior finished surfaces with stable dimension accuracy are possible. Workpieces are fixed by the pressure in cutting.
“Since 1976, we have been solely committed to the field of gear-cutting tools, and have now developed new eco-friendly business through continuous research and development. We will not be satisfied with the present, and to achieve this we would rather work closely with our customers,” remarked the company’s CEO.
