APPLICATION EXAMPLES
Brake disc (Friction ring)
VERTIKCAL MACHINING OF BRAKE DISCS
The challenge:
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.

Process:
- 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
