Before we purchase most previously owned machines, one of our trained technicians thoroughly inspects the machine tool, control, power supply, filtration system and chilling unit. Upon completing this inspection, we can determine if the machine meets our purchasing requirements. After approval from our Service Manager, our technician prepares the machine to be shipped to one of our facilities for reconditioning. Disassembly - After the machine arrives at our facility, it is placed under power to check for any damage during transit. Then the machine tool, worktable area, upper and lower head assemblies, control, dielectric tank and chiller are disassembled for cleaning.
After the machine arrives at our facility, it is placed under power to check for any damage during transit. Then the machine tool, worktable area, upper and lower head assemblies, control, dielectric tank and chiller are disassembled for cleaning.
During this step, our technicians thoroughly clean every component of the Machine. Most worktables are removed, sandblasted, ground, painted and re-qualified. On submersible models, the tank assembly is stripped, repainted and all seals are replaced. The Dielectric Tank compartments are acid washed to remove hard sediments and pump seals are replaced when necessary. All components in the Control and Chiller are cleaned free of dirt and grime and any filter materials are replaced. Exterior painted surfaces of all components will be repainted when needed.
Testing of Components
After the components are cleaned, our technicians thoroughly test each part. If any component is found defective or operating below recommended manufacturer specifications, our technicians will replace them.
Each machine is reassembled to manufacturer specifications and equipped with new consumable items. These include such items as guides, energizing pins, tension rollers, filters and resin.
In this final step, our technicians place the machine under power and prepare it to pass the following test:Backlash Test
Accuracy Test Cut
Taper Test Cut
Metal Removal Rates Test Cut or "Speed Cut"
Our goal is to provide our customers with the highest quality reconditioned EDM. Under no circumstances will a machine leave one of our facilities unless it meets or exceeds manufacturer's specifications, but also the strict standards that McWilliams Sales & Service requires.
