The Operation of the SW Grinder: Quick, Simple, Functional
All control elements of the grinder are clear and of easy access. Its short setup times mean high
productivity and economical effectiveness.
The saw blade diameter is adjusted according a clear diameter scale. The tooth profi le desired (straight
back or round back teeth) is simply selected by a shift lever mechanism. Tooth pitch, tooth depth and
the stock removal or grinding action on the tooth face and the tooth back are set by means of the
respective adjusting screws.
Setting of the face angle or hook is carried out directly by swivelling the saw carrier arm to the desired
position according to a graduated de¬gree scale. The adjustment of the saw blade thickness is done
by means of a dial indicator attachment with clear read-out of the value set. The horizontal mounting
of the saw blade on the grinder means additional ease of set up and excellent sight control of what
you are doing.
The SW Grinder in Operation
The grinder has been set up by the operator. Pressing the start push button, the grinding head will
carry out a cam controlled horizontal movement and in conjunction with the saw blade feed the desired
tooth shape will be generated.
The saw blade feed is effected by a feed finger engaging the saw teeth.
A double feed fi nger system ensures positive movement of saws with broken off or damaged teeth.
Such defectve blades may, however, also be ground by means of master index plates.
An incorporated control gear allows grinding the lead and raker teeth (high and low teeth) in one single
pass.
For side bevelling or chamfering the grinding head is simply tilted up or down according to the diameter
of the grinding wheel mounted.
The SW 450 operates using the dry grinding method and can be optionally equipped with an effi cient
dust extraction system.
The following features are included in the basic machine already:
- Indexing device for grinding the leader and folIower teeth in a single work cycle with steplessly
adjustable tooth heigth difference.
- Feed controller for stepless adjustment of working speed upto 180 teeth per minute.
- FDial gauge for setting blade thickness.
A resharpening device for band saw blades up to 60 mm in thickness is additionally available.
