Konstantin Babayko, Chief Technologist

The main problem at making dies and punches is to choose good-quality cutting tool for special tool steel effective machining before thermal treatment and after hardening (44-58 HRC). This problem is quite pressing if a factory does not have an erosion broaching machine. Besides, some experienced users of dies demand for surface finishing by means of mechanical operations in order to remove defective metal layer remaining after burning and reducing total die resistance.

For today Ukrainian market of cutting tools is filled with products of different manufacturers being within almost the same price range. Our attempts to find the most profitable price-quality-productivity ratio were not a success as there was almost the same quality at a small price difference. It made us paying attention to tools of a higher price category and to Hitachi Tools in particular represented in Ukraine by DETC “Contact”.

First distant knowledge of Hitachi end carbide mills aroused a number of questions and doubts: high price, unusual cutting modes (high feed at slow rotation), no lubricoolant (only air cooling).

In practice Hitachi mills (even economic series) pleasantly surprised us with their capacity and durability as well as good roughness and accuracy at continuous machining of polysurfaces as compared to tolls of different manufacturers.  

I would also like to mention carbide quality: a mill (even uncoated) does not lose its cutting properties after regrinding.

As a result, Hitachi mills prove their value being an adequate substitute for most cheaper mills from different manufacturers, providing high-quality surface and reducing time for its finishing.
