Summit #3 series vertical / horizontal milling machines offer high production accuracy due to their heavy construction and innovative design, which make them the ideal choice for job shops, production shops, repair and tool & die shops. These machines are successfully used for single piece jobs as well as series machining. The large choice of speeds and feeds provide optimum cutting conditions for ferrous and non-ferrous metals.
A few of the outstanding design features are: the alloy steel main spindle in thermally treated and precision ground then fixed on high accuracy bearings; the saddle assembly travels on precision ground slides which ensure rigidity for large capacity table loads; and an automatic lube system ensures consistent lubrication of the speed and feed boxes. Changing of feeds and speeds is easy and efficient, combined with centralized operator controls, these machines are designed for virtually uninterrupted operation.
