How To Adjust The Saw Wheel of A  vertical Band Sawmill Machine

Adjusting the saw wheel on a vertical band sawmill machine is critical for proper blade tracking, tension, and alignment. Here's a general step-by-step guide, but always consult your specific machine's manual, as details can vary based on the model and manufacturer.

⚠️ Safety First:

Turn off and unplug the machine.

Make sure the blade is removed or properly loosened.

Wear appropriate PPE (gloves, eye protection).

Tools You May Need:

Wrenches (typically for tension and alignment bolts)

Screwdrivers

Dial indicator (for precise alignment)

Straightedge or machinist square

Grease or lubricant (as per manual)

✅ Steps to Adjust the Saw Wheel

1. Inspect the Wheels

Check for wear, damage, or buildup of debris.

Clean both wheels thoroughly.

2. Check Wheel Alignment (Coplanarity)

Use a straightedge across the faces of the top and bottom wheels.

The wheels should be coplanar (i.e., their front faces should lie in the same plane).

If they are not, adjust the tilt or position of one wheel (typically the top) using its adjustment bolts.

3. Adjust Wheel Tilt (Tracking Adjustment)

Most vertical bandsaws have an adjustment knob or bolt behind the upper wheel to control tilt.

This helps ensure the blade stays centered on the wheel during operation.

Turn the tracking knob slightly, then manually rotate the wheel to see where the blade tracks.

4. Set Blade Tension

Install the blade and gradually tension it using the top wheel’s tension knob.

Use the tension scale on the machine or a tension gauge.

Too loose: the blade can slip off.

Too tight: risks breaking the blade or damaging bearings.

5. Test Blade Tracking

Manually rotate the top wheel and observe how the blade moves.

The blade should stay centered on both wheels.

Adjust tracking again if needed.

6. Check for Proper Crown

Many band saw wheels have a slight crown (convex shape) that helps center the blade.

Ensure the crown isn’t worn down or flat; this would cause poor tracking.

7. Lubricate and Final Check

Lubricate moving parts if required by your machine’s maintenance schedule.

Double-check all bolts are tightened.

Spin the wheels by hand to ensure smooth rotation and proper tracking.

Pro Tip:

If you're consistently having issues, it may be worth checking:

Wheel bearings (they may be worn or loose)

Blade condition (cracked or improperly set teeth can throw off tracking)

Wheel balance (out-of-balance wheels can cause vibration and misalignment)
