Planer Table Parallelism - Grizzly G0633/G0634 Owner's Manual

Planer Table
Parallelism
Maximum Allowable Tolerances:
Cutterhead/Table Side-to-Side .................. 0.002"
Head Casting/Table Front/Back ................ 0.020"
Tools Needed:
Rotacator ........................................................... 1
Wrench 12mm ................................................... 1
Hex Wrench 4mm .............................................. 1
Hex Wrench 8mm .............................................. 1
Table parallelism is critical to the operation of the
planer. As such, it is essential that the planer table
is parallel with the cutterhead (within 0.002") from
side-to-side, as illustrated in Figure 75.

Figure 75. Side-to-side parallelism of table and
cutterhead.
How the planer table sits in relation to the head
casting from front-to-back is also important (see
Figure 76). The tolerances on the front-to-back
positioning are not as critical as the cutterhead/
table side-to-side positioning. Therefore, the max-
imum allowable tolerance for the front-to-back
parallelism is not more than 0.020".

Table Parallelism Inspection
The easiest way to determine if your planer table
has a parallelism problem with the headstock is to
plane a workpiece and measure the thickness in
multiple locations. If the workpiece is tapered from
left-to-right or from front-to-back, then parallelism
may be a problem.

Use your Rotacator (Page 32) to further inspect
the table parallelism. If you do not have a
Rotacator, a wood block and feeler gauges may
�����
be used, but extra care must be taken to ensure
����
accuracy. If the table is not within the maximum
allowable tolerances, it must be adjusted.

Table Parallelism Adjustments
The table is adjusted with the set screws on the
cylinder liner.
