Kalamazoo 12 Inch 115V 1 HP 1PH Bench Electric Disc Sander with Vacuum

Description

Class 30 gray iron castings form the rigid backbone of the Kalamazoo DS12V Disc Sander, keeping disc runout flat during aggressive deburring work. A 1HP 115V single-phase motor powers the direct 12in aluminum wheel at 1,750 RPM. The vacuum base stops airborne dust, though the small 12in diameter limits part face dimensioning.

Solid gray cast iron forms the disc guard, tilting table, and motor frame to prevent chassis resonance. The single-phase 1HP induction motor draws 11.8 FLA on 115V to rotate the 12in disc directly without intermediate gear reduction. Total unboxed weight reaches 98 lbs, maintaining a bench stance measuring 18in wide by 20in deep.

Key Features of Kalamazoo DS12V

Toolrooms buy Kalamazoo DS12V sanders to chamfer shaft ends, sharpen tool bits, and square flat plate stock. Commercial disc sander pricing includes the integral industrial vacuum collection unit fitted with an internal spark arrestor for fire safety.

• Direct drive 1HP motor rotates the 12in disc without power transfer loss from v-belts.
• Machined cast iron table tilts 45 degrees downward and 15 degrees upward for angle grinding.
• Built-in bottom vacuum system pulls abrasive particulate and metal swarf into a filtration bag.
• Precision balanced aluminum disc plate stops high-speed motor vibrations during fine grinding.
• Heavy cast iron miter slot accepts standard 3/4in by 3/8in miter gauges for crosscut squaring.
• Removable mechanical guard permits rapid peeling and replacement of pressure-sensitive adhesive discs.
• Toggle switch with removable safety lockout key stops unauthorized machine activation.

Wheel Runout Bench Surface Readings

Dial indicator checks on the 12in aluminum disc reveal face runout under 0.001in TIR near the outer perimeter. The cast iron work table stays flat within 0.001in across its entire 14in width. Motor RPM drops less than 25 RPM when pressing 1in cold rolled round bar against 60-grit abrasive paper. Internal motor stator temperature peaks at 134°F under prolonged test cycling. Vacuum blower noise plus disc rotation measures 77 dB at operator distance.

Adjustment Mechanics Shop Servicing Schedule

The table trunnion lock handle secures angle positions with 14 lbs torque, preventing slippage under heavy cast parts. Do not buy this machine for sanding wide panels over 6in width or contour belt grinding. Production fabrication shops deburring massive weldments need heavy 24in floor disc sanders or wide belt machinery.

• Empty the vacuum canvas collection bag and clean the spark screen every 8 hours.
• Wipe the cast iron table top with paste wax every 40 hours to stop surface rust.
• Check the disc mounting arbor set screws and torque to 22 ft-lbs every 100 hours.
