Miniature end mill replaces EDM detailing

Solid carbide miniature end mill is for cutting deep ribs and the slotting in moulds, and also for machining deep corners and precision parts, normally done by EDM methods.

Hitachi Tool's main focus is to concentrate on R and D Engineering; this policy enables Hitachi Tool to be more innovative in bringing new cutting tool technology to the request of the Die and Mould making industry.

As the request becomes greater for more efficient production processes and less EDM 'sparking' times, Hitachi Tool developed the new EPDS Epoch Deep Square.

This solid carbide miniature end mill has been designed for the application of cutting deep ribs and the slotting of moulds, and also for machining deep corners and precision parts, which has conventionally been carried out by EDM methods.

Due to the higher breakage resistance and longer tool life of the EPDS Epoch Deep Square even such difficult operations can be carried out as a safe and economical milling process.

These advantages are the result of Hitachi Tools latest developments in cutting-edge and tool geometries and with regard to the coating technology.

The completely newly developed under-neck shank of the EPDS Epoch Deep Square with its optimum length reduces the danger of tool-breakage and vibration.

In combination with the newly designed cutting edge and flute geometry this end mill achieves higher stability in long overhang machining operations.

Hitachi Tool offers this end mill with the new Hitachi-Nano-coating TH45+.

This newly developed coating achieves longer tool-life than conventional TiAlN-coatings, especially in dry machining of hardened steels.

Another additional unique feature of the EPDB Epoch Deep Square is the increased effective reach length, especially when working on moulds with a draft angle.

E g, In case of machining a mould with a draft angle of 1 deg using a 1mm diameter end mill with an under-neck length of 10mm, the actual effective reach length of the EPDS Epoch Deep Square is 12,03mm.

An end mill with a conventional neck shape can obtain only 10,8mm.
