MF-6220 Automatic Band Saw Blade Sharpening Machine 15-80mm Width 6-25mm Pitch

A dull band saw blade cuts off line and burns the timber, so the operator slows the feed — and the blade dulls further. Sending blades out for sharpening means keeping two or three spares in rotation and paying freight and turnaround on every batch. Hand filing is slow, and the tooth geometry changes depending on who did the filing.

The MF-6220 is a floor-standing automatic band saw blade sharpener. The blade is clamped in a loop on the machine's column, indexed tooth by tooth and ground on a ∅180 * ∅32 * 8 mm cup wheel under coolant. A 370 W grinding head motor drives the wheel, and a separate 120 W feed motor walks the blade through the tooth pattern — so the feed does not stall when the head meets a hard tooth.

Blade width runs 15–80 mm, tooth pitch 6–25 mm and tooth depth 5–15 mm. A silver handwheel sets the cup wheel against the tooth, and feed speed is set on the control panel's Low / RUN / High dial — slow through a hardened tooth, faster through the rest of the band.

Coolant reaches the grinding point through a flexible nozzle, fed from its own tank by a separate pump, and the wheel and pump have independent switches on the front panel. The head assembly sits on a steel cabinet base that stands on the floor.

What the MF-6220 gives you is a blade that is indexed by the machine, ground under coolant, and set up with two motors instead of one.

• Band saw blade width 15 – 80 mm — narrow curve blades and wide resaw bands on the same machine.
• Tooth pitch 6 – 25 mm — covers the pitches used on resaw and narrow band blades.
• Tooth depth 5 – 15 mm — sets the hook without taking the tooth down past its gullet.
• ∅180 * ∅32 * 8 mm cup wheel — a common wheel size, so the wheel is not a single-source part.
• 370 W grinding head motor — drives the cup wheel directly.
• 120 W feed motor — indexes the blade tooth by tooth so the pitch stays even along the band.
• Separate grind and feed motors — the feed does not stall when the head meets a hard tooth.
• Coolant at the grinding point — a flexible nozzle fed from its own tank and pump keeps heat out of the tooth.
• Independent wheel and pump switches — the pump can be run on its own, which is how the trough is washed down between jobs.
• Low / RUN / High feed dial — feed speed is set for the tooth being ground instead of one speed for everything.
• Floor-standing steel cabinet — the head assembly sits on top, so the machine does not take bench space.

For a shop that runs a band saw every day, the MF-6220 turns sharpening from a purchase order into a shift task.

• A blade back in service the same shift. A 15–80 mm band is sharpened in-house instead of shipped out and waited on. Keeping spares in rotation stops being the plan.
• The tooth geometry stops drifting. The blade is indexed by the machine rather than by hand, so the pitch at the last tooth is the same as at the first.
• Two motors, two jobs. A 370 W head motor and a 120 W feed motor keep grinding and indexing independent, so one hard tooth does not stall the feed.
• Coolant where it actually counts. The nozzle feeds the grinding point rather than the machine bed, so the temper survives the grind and the set is not drawn out of the tooth.
• Feed speed you can dial for the job. Low / RUN / High on the panel — slow through a hardened tooth, faster through the rest of the band.
• A standard wheel. ∅180 * ∅32 * 8 mm is a common size, so replacements are not tied to one supplier.

Band saw blades from 15 mm to 80 mm wide, with a tooth pitch of 6–25 mm and a tooth depth of 5–15 mm.

6 – 25 mm. Tooth depth runs 5 – 15 mm, so the hook can be set without cutting down past the gullet.

Yes. A separate 120 W feed motor indexes the blade, so the tooth pitch stays even along the whole band instead of drifting the way it does with a hand file.

Yes, and yes. A flexible nozzle feeds coolant to the grinding point from its own tank and pump, and the wheel and pump have separate switches on the front panel.

Yes. The control panel has a Low / RUN / High dial, so a hardened tooth can be taken slowly and the rest of the band run faster.

With a silver handwheel on the head assembly — one movement sets the cup wheel against the tooth face.

∅180 * ∅32 * 8 mm, a common size, so replacements are easy to source.

Sawmills, resaw operations and woodworking shops that run band saws daily and currently send blades out or file them by hand.

MOQ is 1 set, lead time is 5–8 working days, payment is by T/T, and the machine ships in an export-standard plywood case.
