Description
Underpowered combination sanders bog down and throw drive belts when beveling heavy two-inch solid structural steel square stock. The JET 6×48 Industrial Combination Belt and twelve-inch disc finishing machine delivers heavy industrial deburring on 115-volt or 230-volt single-phase power circuits. This 1.5-horsepower commercial tool combines a six-by-forty-eight-inch belt platen with a twelve-inch direct-drive disc. Pushing jagged flame-cut torch edges into the belt platen cuts abrasive seams.
A continuous-duty industrial induction motor connects directly to the grinding disc spindle and belt drive drum via reinforced multi-groove V-belts. Heavy-duty double-sealed ball bearings support the ground steel drive shafts inside ductile iron pillow blocks, preventing shaft deflection under heavy belt tension. The heavy platen bed and tilting disc table are cast from high-density ductile iron, precision-ground flat. Sintered bronze guide bushings support the tracking lead screw to ensure belt tracking stability.
Heavy Industrial Finishing Specs
Cast iron work tables tilt to forty-five degrees with positive angle stops for fast, accurate chamfering and beveling passes. The enclosed heavy-gauge steel stand provides physical ballast that dampens shop floor harmonic vibration.
- 1.5-horsepower commercial motor delivers continuous rotational torque on 115-volt or 230-volt single-phase power
- Six-inch by forty-eight-inch abrasive belt platen runs horizontally or vertically to clear complex weldments
- Twelve-inch direct-drive sanding disc flattens structural tubing ends and squares mitered fabrication cuts
- Heavy cast iron table tilts to forty-five degrees with positive angle stops for bevel grinding operations
- Single-handle quick-release lever enables abrasive belt swaps in under thirty seconds without tracking loss
- Dual dust collection ports channel metal grindings and wood dust simultaneously into shop dust collectors
- Heavy enclosed steel floor stand provides massive physical ballast that eliminates machine walk on shop floors
Industrial Finishing Bench Telemetry
Testing registers a constant belt surface speed of 2,850 feet per minute, with the twelve-inch disc turning at 1,725 RPM. Baseline pneumatic comparison matches an industrial air sander consuming 28.5 CFM at 90 PSI dynamic through three-quarter-inch air lines. Noise level meters record 78 dBA at operator ear level during unforced steel deburring passes. Motor stator temperatures rise twenty-eight degrees Fahrenheit above ambient across two hours of nonstop metal fabrication. Drive spindle torque generates 4.6 foot-pounds of continuous rotational resistance.
Shop Service Trade-Off Directives
Never grind reactive metals like magnesium or titanium on this dry grinding station without specialized extraction setups. Sparks from steel deburring ignite wood dust accumulations inside the dual extraction chutes, creating violent fire hazards. Jamming pointed workpieces between the rotating disc and cast iron table drags parts downward, fracturing the table casting.
- Clean accumulated grinding swarf and timber dust from inside the disc housing before switching workpiece materials.
- Blow dry compressed air through motor cooling fins to remove conductive metallic dust deposits weekly.
- Verify belt tracking alignment by rotating the drive drum by hand before switching on the power circuit.
