Rise & Fall Table (Click image to enlarge)

OVERVIEW

For semi-automatic operation of:

• Rotary Indexing Machines
• Reflector Polishing machines
• Platen Grinders
• Abrasive Belt Grinders
• Polishing and Buffing Equipment

Munson Rise-and-Fall Tables improve the operation of metal finishing equipment six ways:

1. Fast results
2. Constant speed of abrasive media
3. No wheel dressing
4. Less operator fatigue
5. Better finishes
6. Cooler work pieces

When equipped with a pressure assist work holder such as the Model PHX as shown, additional benefits are realized:

1. Over grinding or polishing can be eliminated
2. Operator is only required to load and unload parts
3. Significantly shorter cycle times due to significantly greater and more consistent pressure than possible to exert manually. In the case of Abrasive Belt Grinding, for example, Model PHX develops up to 2400 lbs. of grinding force, removing up to 1.2 cu. in/sec of cast iron, 3 cu. in/sec of aluminum and 0.4 cu. in/sec of Inconel, titanium, and other exotic alloys (based on 3 sq. in contact area at one time).

Design and Construction

• Advanced, third generation design
• Hydraulically operated, high-pressure assist work holder with 3 HP variable displacement pump, required valving and electrical controls.
• Microprocessor controlled programmable automatic sequencing of in feed and vertical reciprocation. Permits combinations of plunge, retract and reciprocation/spark out cycles.
• JIC electrical controls in NEMA 12 construction. Includes fused disconnects, reduced voltage circuits and podium mounted operator's station with pushbutton controls.
• Vertical suspension consists of heavy-duty, precision, machine tool linear bearings, not ball bushings.

Rise-and-Fall Table Model PHX Workholder

• Hydraulically powered 4 inch infeed stroke length
• Manual 2 ¼ inch infeed stroke adjustment via calibrated locking hand wheel
• Independently adjustable infeed and retraction speeds of 0-8 inch/second
• Two speed infeed. Preset rapid advance at 8 inch/second to set point.
• Adjustable grind infeed at 0-7 inch/second
• 11 ½ inch by 18 inch "T" slot steel work table with steel top bars
• Automatic retract of infeed table at end of advance stroke
• Vertical reciprocation adjustable from 0-6 inch with speeds adjustable 0-4 inch/second
