Product Overview

What the WK450 Does

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.

Key Benefits

Four Reasons Buyers Choose This Model

45 to 180 Teeth per Minute

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.

Easy Angle Depth and Pitch Adjustment

Cutting angle from 0 to 30 degrees, tooth depth to 8 mm and pitch to 25 mm all adjust without tooling changes.

130 kg Installed Weight

No foundation, no rigging crew. The machine sits on a bench or stand next to the saw line.

4200 rpm Wheel Speed

Wheel speed matches the larger WK026, so the finish on a sharpened tooth is the same on either machine.

Application Scenarios

Where the WK450 Is Used

  • Daily resharpening of workshop circular blades
  • Timber and panel saw blade maintenance in small mills
  • Metal cutting blade regrinding in fabrication shops
  • Mobile and on site blade service work
  • Restoring tooth geometry between outside service intervals

Problems It Solves

Three Things This Machine Removes From Your Process

A Full Size Grinder Is Too Much Machine

Not every shop runs 800 mm blades. At 130 kg the WK450 covers the 50 to 450 mm range most workshops actually use.

Blades Go Out and Come Back Late

In house grinding means a blade leaves the saw in the morning and is back on it the same day.

Tooth Geometry Drifts Over Repeated Grinds

Setting angle, depth and pitch deliberately on each grind keeps the blade cutting the way it was designed to.

Manufacturing Process

How the WK450 Is Made

Six stages, each of them completed in our own hall in Shenzhen before the machine is crated.

Frame machined and assembled
Grinding head fitted and aligned
Indexing mechanism set and tested
Motor and electrics wired for the ordered supply
Angle and depth scales calibrated
Test grinding on a sample blade
Quality Control

Checked Before It Is Crated

  • Grinding wheel speed verified at 4200 rpm
  • Indexing repeatability checked over a full blade
  • Angle scale calibrated against a measured setting
  • Ground teeth inspected for depth consistency
  • Electrical and earth continuity check before packing
Customisation Options

What We Change on Request

  • Wheel specification for HSS or carbide tipped teeth
  • Alternative voltage and frequency for your supply
  • Stand or bench mounting arrangement
  • Blade arbors for your bore sizes
  • Operator documentation in your working language on request

How It Compares With Our Other Machines

The WK450 is the workshop machine. Step up to the WK026 when blade size or automation level is the constraint.

Use Guide

Getting Good Parts Off the WK450

  • Check the blade runs true on the arbor before starting
  • Set pitch first, then depth, then cutting angle
  • Start with a light pass and confirm the first teeth before running the blade
  • Match feed speed to stock removal, slower for damaged teeth
  • Let the wheel do the work rather than forcing depth in one pass
  • Keep the wheel dressed so teeth are cut rather than rubbed
Questions

WK450 Questions

What blade range does it cover?

50 to 450 mm diameter, with tooth pitch to 25 mm, grinding depth to 8 mm and blade thickness to 8 mm.

What power supply does it need?

3 phase 380 V at 50 Hz with a 1/2 HP motor. Tell us your local supply and we configure it before shipping.

How long does one blade take?

Feed runs from 45 to 180 teeth per minute, so a typical workshop blade is a matter of minutes.

Can it grind both HSS and carbide tipped teeth?

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.

Does it need a foundation?

No. At 130 kg it goes on a bench or stand, packed at 1300 x 800 x 800 mm.

Can I adjust hook angle?

Yes, cutting angle is adjustable from 0 to 30 degrees.
