DrillMeister -CVT pulley – DMP MCWMB
IMPROVED TOOL LIFE
The goal is to reduce costs in the drilling process for CVT shaft machining.
With the current drill, the drill head needed replacement after 1,500 units.
By applying DrillMeister's special grade "MCWMB", which is a premium material with excellent wear resistance, wear and chipping of the cutting edge were significantly suppressed. This ultimately allowed stable processing up to 2,250 units, achieving significant cost reduction.
