Blade Changes

 

 

 

 

 

 

The vertical metal cutting bandsaw has a flexible continuous blade that cuts in one direction. The type of bandsaw blade and the speed of the blade to be used depends on the workpiece material and the type of cut required.

This type of bandsaw can be used for straight cuts, angular cuts, and curved or contour cuts. Straight cuts are made using workpiece fixtures and with a light, even pressure against the blade. Angular cuts are made with the table and workpiece tilted at an angle other than "0".

When an internal contour cut is to be made, a hole must be drilled in the workpiece. The blade is then cut, fed through the hole in the workpiece, welded together again using the welding station, and re-installed on the bandsaw to make the cut. The welding station can also be used to fabricate new blades and repair broken blades.

The blade is supported by upper and lower tung- sten steel blade guides that keep the blade from wandering during the cut.

The efficiency of the cutting operation can be eas- ily checked by examining the form and color of the metal chips.

ELECTROCUTION HAZARD

This bandsaw is not designed to be used with water soluble cutting fluid or coolant. If needed, use a small amount of oil-based lubricant.

Always disconnect power to the machine when changing blades. Failure to do this may result in serious personal injury.

All saw blades are dan- gerous and may cause personal injury. To reduce the risk of being injured, wear leather gloves when handling saw blades.

To replace the blade:

1.DISCONNECT BANDSAW FROM POWER!

2.Open the upper and lower wheel doors.

3.Release tension on the blade by rotating the tensioning handwheel.

4.Put on heavy gloves, then slide the blade off the upper and lower wheels, around the blade post, and through the table slit.

5.Install a new blade in reverse order.

Workpieces that cannot be supported or stabilized without a vise or jig should not be cut on a vertical metal-cutting bandsaw, because they can unexpectedly move while cutting and draw the operator's hands into the blade causing serious personal inju- ry. Examples are chains, cables, round or oblong-shaped workpieces, workpieces with internal or built-in moving or rotations parts, etc.
