| Summit® 3UH Horizontal
Milling Machines |
SUMMIT® #3 series 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 speed and feed steps 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
Key Features:
- Semi-automatic cycling
- Dual control of spindle speeds
- Vertical attachment with drawbar (3UH & 3UHX)
- Coolant pump and piping
- Drawbar
- Backlash eliminator
- Universal table
