Mechanical repairs, fault elimination and maintenance across all types and sizes of machine tool — we cover the full range.
Minor repairs handle noise, looseness, leaks and wear-part replacement; major overhauls cover strip-down, repair and accuracy restoration of core components — spindle, guideways, ballscrews, gearboxes.
Fit clearances and preload data are recorded through the repair, and post-repair accuracy tests are filed — so the machine tool comes back right and stays right.
We do. Once the guideway pair of a CNC machine is worn, the most reliable way to restore accuracy is still scraping plus adjustment - a craftsman's skill that machines cannot replace. Shallow scoring can be repaired locally; wear beyond tolerance requires re-scraping and dressing. The duration is longer than replacing the guideway set, but the cost is far below new parts, and the mating accuracy is something factory-ground guideways cannot match.
Yes, and in most cases they should be. Machine tool faults are often interwoven: spindle noise may be mechanical wear or drive parameter vibration; accuracy drift may be screw backlash or an encoder feedback problem. We staff both mechanical and electrical lines, so investigating them together means no buck-passing and the repair is right in one pass.
Two things go wrong most often in mechanical repair: replacing without repairing, and repairing without measuring. Below are comparable machine tool mechanical repair scenes.
The value of a large machine tool lies in its base components. As long as castings such as the bed, column and table are not seriously deformed, they should not be scrapped lightly. The route here was: an accuracy health check first to define the boundary between repair and no-repair, then scraping and refitting of the sliding surfaces, pressure plates and gibs fitted to measured wear, lubrication passages cleared and oil grade re-specified for the duty, and finally geometric accuracy re-tested with trial cutting. Castings kept, accuracy restored, at far less than replacing equivalent equipment - and the original process rigidity is preserved.
