Adjustments

Blade guide components

Band saw blades offer enormous advantages to cutting applications, without

requiring any special skills by the operator. A description follows of the blade

guide adjustments required to ensure correct operation of the saw.

Blade guide heads

The first blade adjustment involves adjustment of the heads. The blade guide

heads comprise the blade guide plates which ensure correct longitudinal align-

ment, the blade steady buttons which control vertical blade flexure and the

coolant delivery cocks.

Blade steady buttons

The blade steady buttons prevent upward blade flexure caused by the vertical

action of the cutting force. These buttons are fitted on both the front and rear

heads and need no adjustment.

Blade guide plates

The plate contact points feature widia inserts which guide the blade longitudinal-

ly. A small amount of play must exist between the plates and blade to ensure that

the blade runs smoothly and perpendicular to the work table.

Thanks to the widia inserts, the working life of the guide plates is practically the

same as that of the machine itself. However, if due to wear or the assembly of a

new blade with a different thickness, the following adjustments must be made:

disconnect the machine from the power supply;

slacken the blade tension using the handwheel;
