Innovation Forum: “Increasing Performance”

Increased speed – more partsSpeedcore, for example, facilitates roughly 30% higher cutting speeds in the production of gears. That represents a major advantage for users, who can produce significantly more parts in the same period. “We were able to confirm this enormous performance hike in a series of machining trials at Magdeburg University,” emphasized Heckel during his lecture. The decisive factor here is the intermetallic cutting material that forms the core of the hob. It has a much higher hot hardness.
New coatings for indexable inserts
Nanomold Gold is a rather similar development success in the field of die and mould making. “The design of the coating makes it possible to vary the combination of individual layers and select different layer thicknesses,” explained Heckel. When used with steels up to 50 HRC Nanomold Gold indexable inserts can improve tool life by at least 30%. Another advantage is the very uniform wear along the cutting edge. This guarantees a high level of process reliability in cutting.
Gerhard Melcher explained why users are achieving new speed and tool-life records in the machining of cast materials with the TERAspeed coating. The hardness and temperature-resistance of the new kind of CVD layer facilitate the use of considerably higher cutting parameters than with the PVD AlTiN coatings that are available on the market. “Workpieces are processed much faster with the TERAspeed indexable inserts without this having any detrimental effects on process reliability. Production costs are significantly reduced,” said Melcher.
