The best, most economical way to make some machines perform to their capacity is to rebuild them. Good candidates for rebuild are machines that are less than 12 years old and have a reliable CNC control.  The term “rebuild” refers to a complete overhaul of a machine to its original mechanical specifications without needing a new CNC control. The mechanical components of the machine are cleaned, inspected and rebuilt, using either new or re-machined parts.  Some of the steps included in a rebuild are:

• Rebuilding all mechanical components including replacement of all bearings and seals
• Grinding of the hardened ways or replacement of linear guides
• Ballscrew repair or replacement
• Hydraulic and lube system rebuild including new valves and hoses
• Repair or replacement of way wipers and way covers
• Painting
• Return of machine geometric alignments as well as positioning accuracy to OEM specs.

A rebuild can save about two-thirds the cost of buying a new machine.
