Adjustments 7--9
Blade guide parts
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
alignment, the blade steady buttons which control vertical blade flexure, and the
coolant supply 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
longitudinally. 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 amount of play between the plates and
blade changes, the plates must be adjusted as follows:
" Disconnect the machine from the power supply.
" Slacken the blade tension using the handwheel.
