Scraping of bed ways and spindle bearings is essential for precision and longevity. Scraping bed ways eliminates carriage skewing. This in turn helps to eliminate tracking while grinding. After Wallen, Inc. has achieved a good fit along the length of the bed ways, flaking is added. This flaking provides pockets to trap oil so the carriage rides on a film of oil and reduces the chances of direct metal to metal contact. This minimizes wear on the ways. Scraping spindle bearing is a must for precision grinding. Proper clearance cannot be held unless bearings are scraped for maximum contact and proper clearance. A special procedure is required because the bearings are collapsed when installed and set. Properly scraped and installed bearings can perform for years maintaining proper clearance. |
