CNC Tool Grinder 3 Servo Axes TCT Wheel At 2800 R/min 60-180mm

A blunt TCT blade burns the cut and pulls the saw off line, and one chipped tip is enough to throw the blade out of balance. Sending blades out means keeping spares in rotation and paying freight on every batch. And hand sharpening changes the hook and clearance angles, so a re-sharpened blade never cuts quite the way it did.

The MC-800 is a CNC circular saw blade sharpening machine for blades from ∅120 mm to ∅500 mm. Two 125 × 32 mm wheels grind the rake angle and the clearance angle in the same cycle, and the tooth is indexed automatically at 0–25 r/min on a 400 W servo. The whole work area sits inside an enclosed cabinet behind a viewing window, with the saw blade carried on a horizontal arbor.

The control does three things a manual grinder cannot. On start-up the wheel motor swings itself back to the 90° home position, so the angle is set by the machine rather than by the operator. If the blade has a chipped or missing tip, a skip-tooth function carries on to the next tooth instead of grinding air. And the precision rails are oiled automatically while the machine is cutting teeth.

The machine can also be reached over a network connection: the control supports remote monitoring, service and system upgrades, so an engineer does not have to travel to site to look at a fault. A 0.5 kW motor drives the wheels, a 40 W pump feeds coolant, and the cabinet is wired for 220 V. It stands 1380 × 1000 × 1680 mm at 350 kg.

The MC-800 is a CNC machine, and the things the control does are the reason to buy it — not the wheel.

• Saw blade capacity ∅120 – ∅500 mm.
• Rake and clearance angle wheels, 125 × 32 mm each — both angles come off one setup.
• 400 W servo — drives the machine through the grinding cycle.
• Tooth indexing 0 – 25 r/min — the tooth is indexed by the machine rather than moved by hand.
• 0.5 kW wheel motor — turns the grinding wheels through TCT tips.
• Skip-tooth function — if a tip is chipped or missing, the control moves on instead of grinding air.
• Automatic 90° home position on start-up — the angle is set by the machine.
• Automatic rail lubrication — the precision rails are oiled while the machine is cutting teeth.
• Remote monitoring and system upgrade — the control can be reached over the network.
• Enclosed cabinet with viewing window — the work area is covered while the blade is ground.
• Touchscreen with manual and automatic modes — one tooth at a time, or automatic.
• Handwheel pendant — jog the axes by hand when setting up a blade.
• 220 V supply — confirmed against your supply before the order is placed.
• 350 kg enclosed machine — 1380 × 1000 × 1680 mm, standing on levelling feet.

For a shop that runs TCT blades every day, the MC-800 moves sharpening from a purchase order to a setup on the control.

• Both angles in one cycle. A 125 × 32 mm rake wheel and a 125 × 32 mm clearance wheel mean the blade does not have to be re-mounted between angles.
• A chipped tip does not stop the cycle. The skip-tooth function carries the machine on to the next tooth, so a damaged blade does not become a half-sharpened one.
• The angle comes back to the same place every time. On start-up the wheel motor returns to the 90° home position, so the setting is repeated by the machine rather than by the operator.
• Service without the flight. Remote monitoring and system upgrades mean a fault can be looked at over a network connection instead of waiting for an engineer to arrive.
• The rails look after themselves. Automatic lubrication runs while the machine is cutting teeth, which is when the rails are actually under load.
• Enclosed, so the shop stays clean. The work area is behind a cabinet with a viewing window, and coolant is pumped rather than sprayed.

Circular saw blades from ∅120 mm to ∅500 mm, carried on a horizontal arbor and ground inside an enclosed cabinet.

Yes. Two 125 × 32 mm wheels grind the rake angle and the clearance angle in the same cycle, so the blade is not re-mounted between them.

The control has a skip-tooth function. Rather than grinding air where a tip used to be, it moves on to the next tooth and carries on through the blade.

Automatically, at 0 – 25 r/min, driven by the machine rather than turned by hand.

On start-up the wheel motor swings back to the 90° home position, so the grinding angle is set by the control rather than by the operator.

Yes. The control supports remote monitoring and system upgrades over a network connection, so an engineer does not have to travel to site to look at a fault.

The cabinet is wired for 220 V, confirmed against your supply before the order is placed.

Yes. The work area sits behind an enclosed cabinet with a viewing window, and coolant is delivered by a 40 W pump.

Sawmills, panel and furniture plants, aluminium and metal cutting shops, and any workshop that runs TCT circular saws and currently sends blades out.

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.
