Table Parallelism

Table parallelism is critical to the operation of the machine. As such, it is essential that the table is parallel with the cutterhead (within 0.002") from side-to-side, as illustrated in Figure 22.

Maximum Allowable Tolerances:

0.002"

Cutterhead to Table Side-to-Side

Headstock to Table Front/Back

0.020"

How the table sits in relation to the headstock from front-to-back is also important (see Figure 23). Because the feed rollers, pressure bar, and chip breaker will

be adjusted off the table position, the tolerances on the front-to-back positioning are not as critical as the cutterhead/table side-to-side positioning. Therefore, the maximum allowable tolerance for the front-to-back paral- lelism is not more than 0.020".

Table Parallelism Inspection

The easiest way to determine if your headstock has a parallelism problem 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 par- allelism may be a problem.

Use your Rotacator to further inspect the table parallel- ism. 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 maxi- mum allowable tolerances, it must be adjusted.

Table Parallelism Adjustments

The table is adjusted by turning the chain sprockets underneath the table for movements over 0.016" or by adjusting how the table is mounted on the columns for movements under 0.016".

NOTICE

When making adjustments, tighten fasteners after each step to ensure the accuracy of your tests. When adjusting the chain sprockets, keep in mind that if the chain becomes too loose, it will fall off of all the sprockets. Returning it to its proper location will be frustrating and time consuming.
