WK026 Automatic Saw Blade Grinding Machine
PLC controlled resharpening for circular blades from 80 mm up to 800 mm.
- Grinding diameter range80 to 800 mm
- Teeth distance (pitch)7 to 100 mm

A 130 kg workshop machine that resharpens blades up to 450 mm in minutes.

The WK450 is a compact automatic circular saw blade grinder for blades from 50 to 450 mm diameter. Cutting angle, tooth depth and tooth pitch are all adjustable, feed runs from 45 to 180 teeth per minute, and the 70 to 150 mm wheel turns at 4200 rpm. At 130 kg on a 3 phase 380 V supply it installs next to the saw rather than in a separate room.
Who it is for: Small sawmills, joinery and furniture workshops, metal fabrication shops, and maintenance teams that want resharpening capability without committing to a large machine.
Feed speed is set to the amount of stock being removed, so light touch ups run fast and damaged teeth get the slower pass they need.
Cutting angle from 0 to 30 degrees, tooth depth to 8 mm and pitch to 25 mm all adjust without tooling changes.
No foundation, no rigging crew. The machine sits on a bench or stand next to the saw line.
Wheel speed matches the larger WK026, so the finish on a sharpened tooth is the same on either machine.

Not every shop runs 800 mm blades. At 130 kg the WK450 covers the 50 to 450 mm range most workshops actually use.
In house grinding means a blade leaves the saw in the morning and is back on it the same day.
Setting angle, depth and pitch deliberately on each grind keeps the blade cutting the way it was designed to.
Cast and fabricated frame with adjustable grinding head and mechanical tooth indexing. Wheel specification depends on tooth material and is quoted with the machine.

| Model | Key Specification | Best Suited To |
|---|---|---|
| WK450 | 50 to 450 mm, 130 kg, 3 phase 380 V | Workshop blades and daily maintenance |
| WK026 | 80 to 800 mm, PLC and hydraulic, 900 kg | Large blades and service businesses |
| WK1170 | 15 to 50 mm band width, 220 V, 32 kg | Band blades rather than circular |
50 to 450 mm diameter, with tooth pitch to 25 mm, grinding depth to 8 mm and blade thickness to 8 mm.
3 phase 380 V at 50 Hz with a 1/2 HP motor. Tell us your local supply and we configure it before shipping.
Feed runs from 45 to 180 teeth per minute, so a typical workshop blade is a matter of minutes.
Geometry is handled either way. The wheel has to suit the tooth material, so tell us which you run and we specify it with the machine.
No. At 130 kg it goes on a bench or stand, packed at 1300 x 800 x 800 mm.
Yes, cutting angle is adjustable from 0 to 30 degrees.
Tell us your supply voltage and frequency, the parts you intend to grind and the accessories you need. We reply with a configured quotation and a dated schedule.
