Description
Chipped carbide lathe tooling and rounded end mills stop precision machine shop operations cold. Bolt the Baldor-Reliance 6 Inch Carbide Tool grinder to your sharpening bench for single-point tool dressing at 3600 RPM. Motor output delivers one-half horsepower on 115-volt power. Forcing thick carbide inserts hard into dry silicon carbide wheels cracks brittle carbide tips and stalls the arbor.
Pull the wheel covers down over our solvent wash tank to inspect the precision mechanical wet-end. An industrial motor turns a precision-ground shaft mounted inside a ductile iron motor cylinder housing. Sealed pre-lubricated ball bearings support both shaft ends to eliminate end-play runout during delicate tool sharpening passes. Heavy cast iron tool tables absorb motor vibration while bronze trunnions lock tilt angles rigid, maintaining exact cutting geometry without chatter.
Hardware Performance Matrix Breakdown
Precision carbide tool sharpening demands zero arbor runout and rigid tilt table support. Fleet machinists inspect these seven mechanical hardware features during scheduled bench overhauls.
- One-half horsepower industrial motor delivers continuous 3600 RPM to dress tough carbide tool shanks.
- Six-inch silicon carbide wheels produce razor cutting edges on solid tungsten carbide tools.
- Cast iron tool tables tilt from zero to twenty degrees to grind exact tool clearance angles.
- Reversing drum switch changes spindle rotation direction to dress both right and left hand cutters.
- Protractor work guide aligns tool shanks against the wheel face with angular precision.
- Sealed ball bearings prevent silicon carbide dust and metal swarf from entering motor windings.
- Cast iron base incorporates wide bolt slots for secure mounting to heavy steel workbenches.
Dyno Bench Load Telemetry
Bench testing an equivalent pneumatic industrial arbor requires 34 CFM at 90 PSI dynamic under full sharpening load. Spindle free speed turns 3600 RPM on our bench tachometer but drops to 3250 RPM under heavy carbide tool contact. Air lines lose 12 PSI dynamic pressure drop through 50 feet of hose. Adiabatic cooling causes a 26 degrees Fahrenheit drop, freezing moisture separator trap ports. Breakaway torque reaches 24 foot-pounds while sound output registers 72 dBA at your ear.
Field Service Trade Offs
Dressing carbide tools on silicon carbide wheels generates fine abrasive grit that demands local dust collection and clear operator face protection. Small machine shops running tiny pancake compressors or unlubricated air whips must avoid pneumatic conversions because continuous sharpening starves light air motors. Abrasive wheels require regular dressing on every shift.
- Clean silicon carbide wheel faces with a star dresser to expose sharp abrasive cutting points.
- Check table trunnion lock screws for tightness before beginning single-point tool dressing passes.
- Inspect wheel arbor runout with a dial indicator to prevent tool chatter during sharpening.
