Summit Vertical
Boring Mills |
Summit® Heavy Duty Vertical Boring and Milling Machines
provide a cost effective solution when metal must be machined
efficiently and with precision. 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.
Key Features:
- High precision ballscrews for vertical & horizontal head movement.
- One vertical head with indexing pentagonal turret.
- One side head with standard tool holder.
- One vertical plain ram
(9.5" x 9.5" cross section) head (60" and up).
- Set of four (4) reversible table jaws.
- Precision, hardened and ground gearing.
-
Precision hardened and ground crossrail guideways.
- Totally enclosed electrical equipment cabinet
with state of the art PLC.
- Pressurized lubrication system throughout with oil sight
gauges.
- Power rapid traverse to all heads.
-
Constant surface speed controlled through PLC as standard
feature.
- Centralized full electric pendant control panel for all operations mounted on
a swiveling pendant arm (optional DRO built-in).
- Full length bronze tapered gibbing.
- Chrome-plated
hand wheels and dials.
- Emergency stop switch.
- Wipers on all ways.
- Built-in leveling screws with mounting pads.
- Set of service spanners.
