RETROFiT overhaul increases a machine’s service life. After comprehensive machine diagnostics all the filters in the pneumatic and hydraulic components are replaced. The workpiece, dressing and grinding spindles are overhauled by replacing and re-lubricating the bearings as well as carrying out a function test. If required the components will also be replaced. All relevant infeed axes will be examined and special seals replaced. Our technicians will then implement the planned modification either on site or at a JUNKER plant – to the highest level of quality. Following the RETROFiT, the machines are tested extensively and then re-integrated into production.

Possible scope:

  • Machine diagnostics
  • Basic cleaning
  • Replacement of all filters in pneumatic and hydraulic components
  • Overhaul of:
    1. Workpiece, tailstock, and grinding spindles
    2. Pumps
    3. Relevant infeed axes
  • Replacement of special seals
  • Geometric report
  • Option of replacement machine to bridge the gap


  • Lengthens the service life
  • Increases availability


As an extension of overhaul, RETROFIT renewal offers numerous  additional services, such as revision of the safety technology including an overhaul of the vision panels, pump replacement or overhaul as well as complete replacement of all lines and hoses in the machine’s wet area. In addition, replacement of hydraulic and pneumatic cylinders and other axis components further increases the machine’s service life. To suit special requirements and specific budgets, we can create customer-specific RETROFiT renewal component packages. Component packages can also be combined with RETROFiT upgrades.

Possible scope:

  • Machine diagnostics
  • Intensive machine cleaning
  • Replacement of all filters in pneumatic and hydraulic components
  • Replacement of valves and components in the cooling lubricant circuit
  • Replacement of:
    • Cables, lines and hoses
    • Vision panels

  • Hood and machine base paintwork
  • Warranty for replaced parts
  • Overhaul of peripheral equipment (air filter, cooling lubricant system, etc.)
  • Option of replacement machine to bridge the gap


  • Increased service life
  • Reduced training required in comparison to a new machine
