Machine Tool Rebuild

Konecranes can restore existing machinery to its original mechanical, geometrical and positioning condition. Our rebuild program retains the existing CNC/PLC control and electrics, while rebuilding and optimizing the following mechanical features:

  • Rebuild mechanical components
  • Replace existing bearings & seals
  • Grind & requalify the slide ways
  • Recondition ball screws
  • Refurbish hydraulic & lubrication systems
  • Reclaim original machine alignments
  • Recondition way covers and replace way wipers

By rebuilding your machine instead of replacing it, a significant savings can be realized by utilizing the same foundation, tooling and part fixtures. During a rebuild the existing control and electronics will be maintained. Otherwise, the entire machine will be disassembled to the bare castings. All bearings and seals will be replaced with new.

The machine’s way surfaces will be precision ground or machined to meet or exceed original specifications. All Turcite©/Rulon© will be replaced with new as required. The machine tool’s geometry will be restored to its original specifications.

We will then recondition the spindle to meet original specifications. Your machine will undergo a thorough inspection in the following areas: gears, shafts and major castings. Damage to gears, shafts and castings will be reported and can be repaired at an additional cost.

During the rebuild of your machine, our specialist will completely rebuild the lubrication system. It will be tested for performance and adequate oil flow to all bearing surfaces. All meter units or divider valves will be replaced with new. Damaged lube lines will be replaced with new. All hydraulic pumps will be rebuilt and tested for performance, pressure and flow, and we will replace all damaged hydraulic hoses. We will recondition or replace ball screws and lead screws based upon the inspection for wear. The machine will be painted to colors specified by our customer.

Our specialist will inspect and clean the magnetic panel along with all limit switches and pressure switches. Damaged Sealtite will be repaired or replaced. Our electrical technicians will take the time to disassemble each electrical motor for the purpose of cleaning and replacement of shaft bearings.

Complete documentation is supplied with all machines that we rebuild. All rebuild work performed by Konecranes Machine Tool Service carries a full one-year warranty on parts and labor. Each machine tool will undergo through testing and a run off prior to being re-commissioned and placed back into service.
