It depends. It's hard to say!
The guideway is generally group guide, scraping, first by rail repair principle is determined as a reference guide, and use the standard gauge of grinding point shaving, meet the technical requirements of the flatness, and then use it as the basis for other rail surface finish, scraping, scraping the whole machine tool and precision request.Through the guide rail and standard gauge (or its matching parts) with research and scraping, so that the accuracy of the rail to achieve the required repair methods. Scraping repair method has advantages of high precision, surface appearance, oil storage in good condition and good abrasion resistance, but high labor intensity, low production efficiency, generally applicable to high precision machine tool, or the poor condition of the factory and workshop equipment repair.
Is there a wobble? If the rail wear, is not scraped by rail grinding only, the carriage can shovel, put things down light, turn over, clean, India red painted, and then grinding, see points on the rail, the more the better. Shovel it with a custom white steel knife. When you shovel, use the meter to see how parallel it is with the spindle. Professionals can do it.
