Mounting the Scale Newall Measurement Systems 4 4.0 MOUNTING THE SCALE 4.1 Double End Mounting Note: Refer to section 4.3 for mounting scales in excess of 2.5 metres. Each end of the scale is different and can be identified by the “calibration adjustment end” and the “fixed end.
Mounting the Scale A maximum of two support pillars may be screwed together to allow for sufficient adjustment of the scale. If two pillars are insufficient to enable the scale to be mounted, then additional brackets will be necessary. These brackets must be sufficiently rigid to eliminate any axial movement of the scale.
Mounting the Scale Newall Measurement Systems 6 Remove the link/pin assembly and the scale from the reader head. Drill and tap M8 x 18mm deep (USA 5/16" -18 x 3/4" deep) into the machine casting as marked by the transfer punch. Fit the pillar(s) to the machine casting by using one of the methods shown in Figure 4.
Mounting the Scale 4.3 Scales in Excess of 2.5 Meters Traverse the machine to fullest extent of travel including hand winding past any electrical limits or trip dogs. Insert the set up tube into the reader head, allowing for a sufficient amount of scale to project from the reader head in order to fit the scale mounting brackets.
Newall Measurement Systems 8 Mounting the Scale For scales which are mounted in the horizontal position, spring loaded scale supports are included and should be positioned according to Table 1. Once the locations for the supports have been determined, the reader head should be positioned in the location where the first support is to be fitted.
