Ellis Mitre Band Saw

Description

Structural steel fabricators battle crooked cuts and premature tooth stripping when slicing heavy unistrut or square tube on undersized chop saws. The Ellis Mitre Band Saw provides stationary mitering accuracy and heavy steel stock cutoff capacity across fabrication bays. Blade speed regulates true. However, continuous dry cutting without cutting wax dulls bimetal teeth during heavy channel iron runs.

Teardowns show a built-in oil-bath worm gear reduction drive train driven by a continuous-duty single-phase motor supported by heavy-duty sealed needle roller bearings. The swing arm rotates on a cast iron pivot trunnion to cut forty-five degree miters without moving long stock. Unlike pneumatic saw motors whose phenolic composite rotor vanes scuff from dirty shop air, this direct-drive gear reduction unit transfers motor torque without air pressure fluctuation or pneumatic line condensation wash-out.

Structural Steel Sawing Hardware Matrix

This stationary mitre band saw delivers structural pipe, channel, and solid bar cutoff capabilities for commercial welding shops. The rotating head configuration eliminates material repositioning when executing compound angle miter cuts.

• One-horsepower motor maintains consistent blade torque across three selectable speeds from 70 to 210 FPM.
• Eleven-foot-one-inch bimetal blade spans one-inch width to prevent lateral wandering in thick plate.
• Mitering head swings sixty degrees to produce clean miter cuts while long stock stays clamped.
• Built-in air cylinder downfeed control regulates head descent speed to prevent tooth stripping.
• Heavy cast iron vise clamps wide structural flange beams firm against the reference fence.
• Sealed needle roller bearings guide the blade within carbide wear pads for true vertical kerfs.
• Heavy welded steel base frame absorbs cutting chatter during continuous ten-hour production shifts.

Rotary Dyno Bench Comparison Telemetry

Dynamometer testing evaluates this stationary saw against industrial pneumatic cutoff equipment drawing 35 CFM at 90 PSI dynamic across multiple air drops. The electric worm drive sustains 185 loaded blade feet per minute from a 210 free speed rating, avoiding the twenty-PSI dynamic line drop typical of long plant air headers. The motor avoids the 34-degree Fahrenheit adiabatic exhaust drop that freezes pneumatic saw motors. Clamping downfeed force delivers 400 pounds of cut pressure, producing an acoustic sound pressure rating of 81 dBA at technician ear level.

Field Service Directives Maintenance Boundaries

This mitering band saw streamlines structural steel fabrication but shows clear installation limits. Mobile field service trucks should not attempt transporting this machine because the heavy 500-pound cast frame requires permanent concrete shop anchoring. Forcing hardened tool steel bar stock past recommended downfeed rates strips teeth off bimetal saw blades.

• Coat bimetal saw blade teeth with solid cutting wax stick before slicing thick solid bar stock.
• Purge metal chips from the blade guide bearings and wheel brush using clean dry compressed air.
• Inspect worm gear transmission oil level through the gearcase inspection plug twice each year.
