Introduction

The ShopBot Automatic Tool Changer (ATC) automates the bit changing process during projects that 

require multiple tool changes. The ATC system includes a 5HP HSD spindle, a pneumatically-assisted 

Z-axis, six-position tool bank standard, up to eight tool positions for our four foot wide tool (10 for a 

five foot and 12 for a six foot), fixed-position Z zero plate, chuck holder, pneumatically operated dust 

skirt, and ATC interface card. 

The ATC reduces the time a project must remain on the machine by automatically changing cutting 

bits between cuts, thus eliminating the need to change and calibrate tools by hand. The ATC allows 

the PRSalpha to cut complete projects where tool changes are required without additional inputs.

The 5HP HSD spindle assembly is fan cooled - in the lower part it has air cooled bearings. The ATC 

requires 6-7 cfm @ 90 psi of compressed air; PORTABLE AIR COMPRESSORS ARE NOT RECOM-

MENDED as they can have trouble keeping this pressure reliably and have a reduced service life. 

The ShopBot ATC is available in the following voltages:

(#12520) HSD ATC 5HP 220V 1PH 

(#12521) HSD ATC 5HP 380/460V 3PH 

(#12540) HSD ATC 5HP 230V 3PH  

The ShopBot ATC can be an upgrade to the E series (aluminum table sides) PRTalpha machines with 

the addition of a retro Z-axis. The E series table allows for crucial table positioning without a complete 

rebuild of the table. See ATC table plans before installation. 

Safety Note

While running the ATC, ensure the compressed air is connected prior to turning off the power. If the 

compressed air is NOT connected, and the power is turned off, the spindle will crash to the table.
