Adding a Tool Changer To HAAS TM-1 CNC Milling Machine

I recently bought a 2005 HAAS TM-1 that didn't have an umbrella tool changer. Fortunately, it had the machined mounting area at the top of the column for the tool changer arm. Unfortunately, HAAS won't sell you a tool changer for an open machine, even if you intend to close it. They will sell you the support arm though, so if you can find a used tool changer from a TM-1 or Mini Mill, then you can add it to your TM-1.


▶ Tool Changer - From HAAS if your machine is enclosed. Otherwise need to find a used one pulled off a machine in hopefully good condition.

▶ Tool Changer Arm # 20-1118E - Direct from HAAS

▶ Leeson Umbrella Shuttle Motor 24 RPM. Replaces Haas # 32-1875 Tool Changer Motor -

Watch Part 1: Installing the Support Arm

The tool changer support arm is part# 20-1118E Description is T/C SUPPORT ARM MACHINED. The Revision is E, and the main difference from the original support arm is that this arm goes horizontal first over the backsplash and towards the front of the machine, and then descends vertically.

Watch Part 2: Installing an [Inexpensive] Shuttle Motor

The tool changer that I purchased to add to our HAAS TM-1 was missing the umbrella shuttle motor (Haas # 32-1875). I was able to purchase the motor for much less expensive than what HAAS charges. This motor is the same quality, made by LEESON, and advertised as a direct replacement for the stock motor.

At the time of this installation in 2022, this motor cost $260, which is $400 less than HAAS OEM motor, which costs $665 (Feb 2022 price).
