VM-E

The VM-E Vertical Milling machine is available in two versions, the Standard Drive and the Vari-Speed.

The Standard Drive VM-E has nine spindle speeds, which can be simply achieved with belt changing, with the motor on a hinged platform to facilitate speed changing.

The Vari-Speed, with variable speed controller, provides four variable speed ranges giving 40 - 3000 r.p.m., 70 - 524 r.p.m., 228 - 1714 r.p.m. and 370 - 3000 r.p.m.

The machine has a well constructed column and base, the substantial column being a box type with full length vee slideways, in preference to the more common tube and key column. Complete with cast iron base, it comes ready-mounted on a heavy gauge sheet steel stand, which incorporates a chip tray.

Experience has shown that vee slideways are the best for machines of this type. With taper gibs for adjustment, Vee slideways automatically provide control in two planes. By manipulating two precision adjustments for fit along the slide can always be obtained. Hand scraped slideways ensuring greater rigidity, geometrical accuracy and improved effectiveness of slideway lubrication, leading to a more sensitive machine which is easy to operate and has a longer accurate life.

The surface ground table has three 14mm (9/16") tee slots, with table traverse stops located in the tee slot on the front face. The table and cross slide feednuts are of the split type, so that adjustment can be easily made to accommodate wear and table feedscrews are provided with ball type thrust races.

An optional table power feed unit, with infinitely variable feed rates from zero -600mm/min.(0-2ft/min) are available for both standard drive and Vari-Speed VM-E's. These units can either be supplied factory fitted to a new machine, or retro fitted to an existing machine by the user. The unit features an on/off switch, forward/reverse direction switch, potentiometer speed controller and a rapid traverse button. The unit is powered by an 110 volt, single phase, 50/60Hz motor and is wired via a transformer through the main motor push button starter.

The Milling head is arranged to swivel up to 45 from zero in either direction about both the horizontal and vertical axes. The quill is fitted with an effective clamp, a scale and depth stop and a hand operated fine feed, via a worm and wheel with micrometer depth stop.

Much of the work carried out on turret milling machines is end milling with cutters held in collets. The R8 taper spindle, takes the collet directly into the spindle nose. This keeps the distance between the spindle bearing and the end of the cutter to a minimum, ensuring maximum rigidity.

The spindle itself is mounted in a pair of pre-loaded angular contact bearings, fitted back-to-back at the spindle nose end, with the tail end supported by a pair of deep groove ball bearings. This arrangement will accommodate heavier workloads and give higher performance levels.
