Automatic Tool Changer (ATC) Installation Manual • December 1, 2016

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

ve foot and 12 for a six foot), xed-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 o the power. If the

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

ATC Installation (Mechanical)

This section assumes that, except for the table assembly (a drawing for this is provided under “Table

drawing”), the ShopBot has been assembled using the instructions provided in the ShopBot assembly

manual. This means that the ShopBot is at a point in which it is able to connect and move under the

control of a computer. Wire/cable management may be left until the ATC installation has been com-

pleted.

VERY IMPORTANT! For New Table Setups

The location of the table bed is extremely critical for ATC. Excess overages in the X dimension could

mean tooling collisions, insucient cutting area, and dropped tooling. At the end of this section there

is a table drawing that shows how the table should be set up. Pay close attention to the relationship

between table sides and the table surface.

For Previously Assembled Tables

Loosen the bolts that are attached to the table side extrusions and slide table sides in the positive X

direction until the table is in the position called out in the table drawings at the end of this section.

Mounting the Spindle

The ShopBot ATC is equipped with a 5HP HSD spindle. The spindle

is cooled by an electric fan, but also has air-cooled lower bearings.

The air required for cooling the lower bearings is 60 psi (4 bar).

The spindle also has an internal drawbar that holds the tool cones in

place during cutting; this requires 90-100 psi (6-7 bar).

Power up the ShopBot and position the YZ car so that it is in a

location where the front and back of the Z-axis may be reached.

Use the keypad mode (K) on the computer to move the Z-axis to a

height close to the table’s surface.

Rest the spindle on its end as seen to the left. Position the Z-axis

up or down using the keypad mode again until the holes in the

Z-axis align with the mounting holes in the spindle plate.

Tighten spindle securely to Z-axis with six 5/16”x 1 1/2” socket

head screws.

Mount Dust Collection Bracket

Pry black plastic cap from top of Z-axis with a at

head screwdriver. Pre-assemble two 1/4-20x1/2”

button head screws and two 1/4-20 T-nuts through the

dust hose guide bracket. It may be necessary to slit

the top sticker down the left side of the Z-axis extru-

sion. Slide the bracket down into the extrusion and

tighten the bolts. Replace black plastic cap.

Use hose clamps to run a 4”dust collection hose to

the dust skirt from an overhead dust system. Do not

connect hose until the end, due to possible inter-

ference through the rest of the installation.

Mount Upper Y-Axis E-Chain Bracket

The pneumatic assist regulator and manifold are pre-mounted on the upper Y-axis E-chain bracket.

Align holes in bracket with tapped holes on the back left side. Secure bracket with two 1/4-20x1/2”

socket head screws, 1/4” lock washers and at washers. Tighten screws securely.

Mount Tool Bar

Pre-assemble tool bar mounting bracket with four 5/16x3/4” button

head screws, 5/16” at washers, and 5/16”T-nuts.

Insert pre-assembled tool bar mounting brackets into the T-slot grooves

on the bottom of the tool bar (tab facing up).

Slide nuts into the bottom slot of the table side, as shown in the

photo. Position the tool bar o the end of the table based on the table

drawing provided.

Note: It may be necessary to adjust this dimension so that the spin-

dle is able to reach the clips on PRTalpha models. Before tightening

the mounting bolts, turn on the machine and move the axis to ensure

that it will reach the toolbar without hitting the mechanical stops.

Automatic Tool Changer (ATC) Installation Manual • December 1, 2016

Level the tool bar by placing a level on the xed Z zero

plate (pre-attached to tool bar), then securely tighten all

5/16” button heads in tool bar mounting bracket.

Mount Tool Chuck

The tool chuck is used to hold the tool holder cone while changing

collets and bits. Use 5/16x3/4” button head screws and T-nuts to

mount the tool chuck in the second slot from the bottom of the ta-

ble extrusion. If this location is not optimal, mount the chuck where

it is most convenient.

Mount Main Air Assembly

Mount the pneumatics in the bottom extrusion slot

on the back table side. Ensure the pneumatics are

positioned as close to center of the table as possible.

Secure pneumatics with two 5/16x3/4”button head

screws and 5/16”T-nuts.
