REBUILT AS NEW Vertical Boring Mills
 |
|
Summit REBUILT Vertical Boring Mils provide a cost effective solution to increaseing prices of new machines. These factory rebuilt VBMs offer EVERYTHING a NEW machine has, at a much LOWER COST.
Summit's 48" & 60" (single column) and 80" - 120" (double column) VBMs incorporate many advanced construction features, utilizing the latest technologies to ensure high performance and meet the ever increasing demand for greater productivity; considering at all time the need for versatility, easy maintenance, and economical production cost.
A few of these outstanding design features are: heavily ribbed, closed grain castings which have been heat treated and stress relieved. These castings offer virtually the same thermal coefficient of expansion as steel while maintaining excellent dampening characteristics which provide enhanced dimensional part accuracy and constant surface quality. A large diameter Timken type taper roller bearing offers excellent table loading capacity and accuracy with work table run-out having axial and radial T.I.R. of 0.0005". Hardened and ground pinion/bull gear table drive provides constant tooth contact for smooth and vibration free turning combined with main A.C. brushless spindle drive for smooth running, superior speed control and maximum reliability. Independently, all axis are driven by servo motors thru 1/10 Alpha Reducers for high torque and smooth feeds.
