MC-800 CNC Circular Saw Blade Grinder For TCT Blades 120-500mm

A dull carbide blade burns the trimming cut and loses the line. One chipped tip puts it out of balance, and a re-ground blade never cuts like a new one. Sending blades out adds a spare set and freight; hand grinding changes the hook and clearance angles.

The MC-800 is a CNC circular saw blade grinder for blades from Ø120 to Ø500 mm. Two 125 * 32 mm wheels grind the rake and clearance angles in the same cycle, so the blade is not re-mounted between angles. A 400 W servo indexes the teeth at 0–25 r/min along an arc, and the working area is enclosed in a cabinet with a viewing window.

The control does three things a manual machine cannot. The wheel motor swings back to a 90° home position on start-up, so the angle is set by the machine. A jump-tooth function moves to the next tooth when a tip is broken, instead of grinding air. And the precision rails are lubricated automatically while the teeth are indexed.

It also supports remote monitoring, service and upgrades over a network, so a fault can be reviewed before an engineer travels. A 0.5 kW motor drives the two wheels, a 40 W pump delivers coolant, and the cabinet runs on 220 V at 1380 * 1000 * 1680 mm and 350 kg.

What the control system does, and what that changes at the machine:

• Blade capacity Ø120–500 mm — the range covers the TCT blades used on sawmills, panel shops and metal cutting benches.
• Two 125 * 32 mm wheels — rake and clearance angles are ground in the same cycle, from one set-up.
• 400 W servo — drives the tooth indexing cycle instead of an operator turning a handwheel.
• Tooth positioning 0–25 r/min — the machine sets the tooth position, not the operator.
• 0.5 kW wheel motor — turns both grinding wheels through the TCT tips.
• Jump-tooth function — if a tip is chipped or broken, the machine moves to the next tooth instead of grinding air.
• Automatic 90° home on start-up — the grinding angle is set by the control, not by hand.
• Automatic rail lubrication — the precision rails are lubricated while the teeth are being ground, under load.
• Remote monitoring and upgrades — the control system can be reached over a network connection.
• Enclosed cabinet with viewing window — the working area is covered while the blade is being ground.
• Touchscreen, manual and automatic modes — one tooth at a time or a full automatic cycle.
• 220 V supply — confirm it against your shop supply before ordering.

What changes in a shop that grinds TCT blades every day:

• Grinding moves from a purchase order to a setting. A shop that runs TCT blades daily can put a worn blade on the machine and set the angles on the control panel instead of sending it out and waiting.
• Both angles in one cycle. The 125 * 32 mm rake wheel and the 125 * 32 mm clearance wheel work from the same set-up, so the blade is not re-mounted between angles.
• A chipped tip does not stop the cycle. The jump-tooth function moves to the next tooth, so a damaged blade does not come back half sharpened.
• The angle returns to the same place every time. The wheel motor swings back to its 90° home position on start-up, so the setting is made by the machine rather than by the operator.
• Service without a flight. Remote monitoring and system upgrades mean a fault can be reviewed over a network connection before anyone travels.
• The rails look after themselves. Automatic lubrication runs while the teeth are being indexed, which is when the rails actually carry load.
• The shop stays clean. The working area sits behind a cabinet with a viewing window, and coolant is pumped rather than sprayed.
