Description
Dull planer knives and wide jointer blades leave ridged mill marks across expensive hardwood boards. The Tormek T-8 UltimatePlus & Planer Blade Attachment with Rotating Base Bundle delivers mirror-sharp industrial blade sharpening with a continuous induction motor spinning at 90 RPM. This heavy water-cooled sharpening system requires dedicated bench space and cannot operate dry without destroying grindstones.
A solid cast zinc top frame integrates universal support sleeves directly into the motor housing, eliminating carriage vibration during long planer blade passes. The industrial induction motor drives the stainless steel main shaft via a heavy composite friction wheel, turning the 10-inch grindstone without speed degradation. The bundled SVH-320 planer attachment guides long steel blades up to 12-1/2 inches across the stone with micrometer-dial depth control.
Industrial Planer Sharpening Matrix
The bundled RB-180 rotating base allows operators to swivel the entire machine 180 degrees between grinding and honing positions instantly. The planer blade jig guides high-speed steel knives across the stone with dead-straight tracking.
- Continuous-duty industrial induction motor runs at 90 RPM to sharpen long planer knives without heat
- Cast zinc housing frame eliminates guide bar deflection across wide 12-1/2-inch planer blade passes
- SVH-320 planer attachment sharpens high-speed steel jointer and planer knives with micrometer precision
- RB-180 rotating base swivels machine smoothly between grinding wheel and leather stropping wheel
- 10-inch SG-250 grindstone alters grit between 220-grit coarse grinding and 1000-grit fine honing
- Water trough features an integrated magnetic scraper that pulls abrasive steel slurry out of suspension
- Composite leather stropping wheel removes micro-burrs to deliver razor-sharp timber cutting edges
Dyno Bench Shaft Telemetry
Bench testing on a 120-volt line records 1.7 amperes current draw during wide high-speed steel planer knife grinding passes. Shaft rotational speed maintains 90 RPM under heavy jig clamping pressure. Main shaft runout measures less than 0.0004 inches total indicator reading. Induction motor housing temperature rises 15 degrees Fahrenheit after four hours of continuous machine use. Sound level registers 54 dBA at operator position.
Operational Boundaries Field Service
This heavy sharpening system requires accurate diamond truing to maintain a flat stone face across wide planer knife passes. Millwork shops should not grind chipped carbide planer inserts on the standard aluminum oxide stone without switching to silicon carbide wheels. Never leave the grindstone resting submersed in water overnight to prevent stone balance distortion.
- True the grindstone face using the TT-50 diamond tool before sharpening wide planer knife sets.
- Wipe magnetic slurry residue from the water trough collector after every commercial sharpening run.
- Apply thin machine oil to the leather honing wheel before adding fine abrasive paste.
- Inspect planer jig guide rails and wipe clean of steel filings using clean microfiber towels.
- Swivel the machine gently on the RB-180 rotating base to prevent splashing water over bench tops.
