Reduced cycle times and high demands on axial run-out and the reference geometry of the brake disc
The solution:
WEISSER precision lathe with customized process solution
The modularly structured single- or multi-spindle pick-up machine models of the UNIVERTOR AM series and UNIVERTOR A are used for the multifunctional machining of brake disks.
Realization of subsequent operations in one work area with drastically reduced downtimes and high precision
High precision thanks to reduced reclamping losses and special clamping techniques optimized to the machine and process
Original WEISSER technology module, NC-straddle toolholder for the plane parallel machining of the friction surfaces
Built-in drilling station with adapted pitch circles for the fastening bores
Original WEISSER precision turning spindle, optimized for robustness with simultaneously maximum concentricity and axial run-out precision for an optimal turning result on the brake disk
The pick-up method developed by WEISSER offers a high degree of automation and prevents chips from being spread and workpieces from being contaminated
Versatile automation components load the machines, connect different production lines, integrate test steps and can be adapted at any time to extensions.
Complete machining of rotation-symmetrical workpieces with large diameters, e.g. of friction rings for automobile braking systems
Workpiece run-through from left or right with short traversing paths thanks to technology integration in one work area
Individually tailored use of various tool systems, e.g. driven tools of a tool block
Use of multi-spindle drilling heads and direct drive (Y axis) for producing through holes
Special clamping device for compliance with minimum tolerances
In-process measurement
Flexible automation solution with turning station for the required workpiece position of the subsequent operation
Process-integrated workpiece transfer for various workpieces with exact compliance with the corresponding surface requirements
Finish machining of the friction ring with NC-straddle toolholder
Measuring, testing and monitoring systems do not allow tolerances to be exceeded. Result: High process reliability, workpiece precision and machine availability
