Balzers, specialist coatings presents the new Balinit Helica in the biennial exhibition in Bilbao. This innovative coating opens a new chapter in the performance of drill bits
Excellent hardness hot, high resistance to wear, excellent evacuation of chip - these features summary of the qualities that manufacturers and users of drill bits are interested above all. The second generation member of the G6 Balzers, Balinit Helica, offers a clear advantage in performance on the titanium based coatings. It is appropriate for all grades of steel and cast iron, for both internal and external cooling and, even, for machining in dry or with minimum amount of lubricant.
Minimum wear, high hot hardness
The first improvement in performance is related to the inherent qualities of the G6 generation AlCr based coatings: high resistance to abrasion protects the drill channel, while the accession in the lip is very low. This coating of copper color has a maximum temperature of work of 1,100 ° C, a microhardness (HV 0.05) of 3000 and a high level of resistance to oxidation.
Structure multi-layer for tenacity and resistance against cracking additional
A second crucial improvement is derived from the structure multi-layer coating PVD (physical vapour deposition), which gives it a high resistance to shear and, therefore, ensures a very uniform wear. There is less tendency to cracking in the corner of Court of the drill and the tenacity has increased considerably.
The smooth surface facilitates removal of the swarf
Thirdly, the extremely smooth surface of the coating allows the chip to flow smoothly during the drilling. With these features, the Balinit Helica exceeds coatings of titanium aluminum on common pieces of work.
