Radical improvement in service life for increased availability of grinding machines

OVERHAUL – Extending the service life of grinding machines

With RETROFiT OVERHAUL, basic steps are taken to increase service life and, therefore, the availability of grinding machines. After the machine undergoes extensive diagnostics, all filters are replaced on the pneumatic and hydraulic components. Workpiece spindles, dressing spindles and grinding spindles are reconditioned, a process which includes replacement of the bearings, re-lubrication and carrying out a function test. If required, components can be replaced to increase the service life. All relevant positioning axes are worked on and special seals replaced. The scheduled modification work can either be completed on site or at a JUNKER and ZEMA facility – no matter the location, it will be conducted professionally and to the highest quality standards. Following the RETROFiT, the overhauled grinding machine is thoroughly tested and integrated back into the production line.

Possible scope:

  • Machine diagnostics
  • Deep cleaning
  • Replacement of all filters for pneumatic and hydraulic components
  • Overhaul of:
    • Workpiece spindles, tailstock spindles and grinding spindles
    • Pumps
    • Relevant positioning axes
  • Replacement of special seals
  • Geometric report
  • Option to bridge the gap with replacement machines

Benefits:

  • Extended service life
  • Increased availability

Long-term increase in the availability of grinding machines

RENEWAL – Further steps to increase the availability of grinding machines

Supplementary to OVERHAUL, RENEWAL offers numerous additional services, such as reworking the safety technology including overhauling the inspection windows, replacing or overhauling the pumps, as well as completely replacing all lines and hoses in a grinding machine's wet area. In addition, replacing the hydraulic and pneumatic cylinders and other axis components further increases the machine's service life and availability. The various elements of RETROFiT RENEWAL can be selected individually, making it possible to respond to particular requirements and meet specific budgets. Furthermore, you can choose to combine this with RETROFiT UPGRADES for grinding machines.

Possible scope:

  • Machine diagnostics
  • Intensive machine cleaning
  • Replacement of all filters for pneumatic and hydraulic components
  • Replacement of valves and components in the coolant circuit
  • Replacement of:
    • Cables, lines and hoses
    • Inspection windows
    • Workpiece spindles, tailstock spindles and grinding spindles
    • Pumps
    • All CNC axes
    • Cylinders
  • Geometry measurement
  • Painting the hood and machine stands
  • Warranty covering replaced parts
  • Overhaul of peripheral equipment (air filters, coolant system, etc.)
  • Option to bridge the gap with replacement machines

Benefits:

  • Extended service life
  • Increased availability
  • Reduced expenditure on training compared to new machinery
