Universal tap offers top performance
A high-volume, high-speed business: producing threads often takes tools to the very limit. That is also and especially true of cutting techniques. LMT Fette’s Type V machine tap provides a high-performance solution for machining the main steel, cast iron and non-ferrous materials.
Today’s machining centres can precisely synchronize spindle rotation and feed and standard cutting speeds are significantly higher. Naturally, both of these together have an impact on tools, which are subjected to much greater strains.
LMT machine taps have been designed to meet these challenges – for example, using an optimized cutting geometry that reduces friction with an increased profile relief angle. This also prolongs tool life. These advantages are also offered by the Type V tap for difficult-to-machine high-alloy materials. The spirally fluted Rasant model can be used on all blind holes and the Markant model with spiral point was designed for all through-holes.
“This universal tool can be used in a very wide range of applications. Additionally, not only is it suitable for use with most steel, cast iron and non-ferrous materials, but it enables enormous performance increases,” explains Stefan Möller, team leader for product and process engineering in the field of thread-cutting and milling. This positive appraisal is backed up by countless practical results – for example, the tools achieved a tool life quantity of 450 units in the production of M14 x 1.5 blind threads in crankshafts made of forged steel with a tensile strength of 750 N/mm2. Compared with competitors’ standard products, this result represents an increase of 360%. “In this case it was possible to reduce tool costs per component by 70%,” explains Möller.
