Milling | CPMill - Complete Performance MillingThe main challenge during ball track milling is toreliably achieve the demanded track clearance,fit and contact angle allowing for the adjustmentangle. The tolerances here lie in the µ-range.In order to be able to meet these high geometricdemands, ball track milling cutters have beenmade to date only with axially parallel solderedblades. MAPAL CPMill ball track milling cuttersare now available in the new generation also withinclined (helically installed) blades. With speciallydeveloped 3D methods for the design, the latestproduction facilities and optimised measuring programmes,MAPAL can produce these replaceableheads also with the proven high accuracy. For themachining result that means higher milling quality,and at the same time improved cost-effectiveness.Soft cuttingDuring the milling of ball tracks, the completegeometry of the tool is imaged in the workpiece.If vibrations occur during machining, these leadto deviations from the track form and to microstructurecracking at the blades. The helicallyarranged blades of the new CPMill ball trackmilling cutters contact the workpiece with a softcut. Vibrations are practically eliminated comparedwith axially parallel blades. The result is smootherrunning of the tool, and hence a better track form andsurface quality. The smoother running also preventsmicrostructure cracking at the blades. The blade thusremains sharp for longer, and the tool life increases byup to 30% compared with tools with axially parallelblades.Optimum cutting materialOf crucial importance for the tool life is the cuttingmaterial. In this respect, the MAPAL CPMill balltrack milling cutters bring important furtherdevelopments to the market. New PCBN gradesoptimised and developed specially for hard millingallow the machining costs to be further reduced.Particularly important for the choice of the grade is adetailed analysis of the material to be machined.MAPAL offers know-how and engineering for completesupport – from the choice of the right PCBN gradethrough the optimisation of the existing productionprocess right up to Tool Management.Soft millingMAPAL manufactures solid carbide milling headsfrom the CPMill Series also for soft milling, andthus offers a complete system for the machining ofconstant-velocity joints.7
