An analysis of the work to be performed should be made and the proper blade selected. The blade should always be inspected before installing on the machine. Things to look for should be the smoothness on the sides and back edge of the weld, look for any missing teeth, or impacted chips. The blade guides may now be selected and inserted into both the upper and lower guide holders. Proper adjustment of these guides takes place when they form a complete “V” shape (see graphic below) and support the blade equally on each side. A couple of thousands on each side of the blade will provide the running clearance and support for contour sawing.
Note: Blade guides should be cleaned of chips each blade change or more frequently if required.
BLADE GUIDES
The back end roller that supports the back of the blade on each guide holder contains a hardened cap over a set of ball bearings. This should be checked periodically for free movement so it is allowed to rotate freely as the back of the blade comes in contact with the face of this roller. Noticeable friction in this assembly indicates it should be replaced. This can be done by removing the right hand guide insert, moving the left hand guide up away from the bearing face. Loosen the setscrew on the bottom of the guide holder and sliding the old bearing and shaft out and a new one in. Tighten the setscrew and
The “V” type solid blade guides and holder assemblies as furnished standard with the machine are recommended for the majority of cutting applications. This is true for the cutting of materials at blade speeds in the low range.
If the machine is operated in the high range, it should be operated with the
NOTE: If machine is operated in excess of above, abnormal blade wear and breakage may occur, due to the increased heat developed with the standard solid guides.
