System shown in the horizontal and vertical positions

Multiple systems are available depending on the application and the available measurement envelope of the optical gaging machine
All feature adjustments that are found on the single system operate independent on each of the multi system modules
Horizontal and vertical axis rotate all modules together at one time
System shown in the horizontal and vertical positions

Housing and Spindle can be rotated in the Horizontal and Vertical position, this motion can be performed with product in place
Fine rotation adjustment can be performed in either position

Precise positioning of product can be quickly performed. Precision detents are located on product holding pins for proper part placement
There are two sets of holding pins which are used for either small or large diameter products
CUSTOM spindle adapter plates are available to meet your product needs
