MMTJ Machine Description

The MMTJ CNC Miter Mortise and Tenon Machine Center is tailored specifically to meet high-volume production requirements. Offering flexibility as well as productivity, the MMTJ provides high quality mitered mortise and tenon parts for use in cabinet door construction.

The MMTJ is built on award winning technology. It won the “Challengers Award” at the 2004 IWF fair in Atlanta, Georgia.

Standard Operation

Parts are placed into the work zones, referencing the back and side fences. The start button is pressed, and the clamps secure the part into place. The machining is ready to begin in the work zone. There are 2 zones standard in the MMTJ allowing for pendulum processing. While one part is being machined, the other zone can be loaded and queued for machining.

There are three CNC controlled axis, one in the X (left to right), one in the Z (up and down), and one in the Y (in and out).

What the MMTJ Does

mmtj sample part

The MMTJ is typically used to perform the following operations:

1. Cuts 45 degree miters on profiled hard wood, soft and/or MDF
2. Cuts tenons right into the wood itself in zone 1.
3. Drills mortise pockets into the part in zone 2.
4. This machine will produce 175-200 miter doors per 8 hour shift.

The easy to use software allows the operator to change from one saved program to another in seconds with only two touches to the screen.
A password protected edit feature allows quick and easy editing of existing programs or creating new programs. A new program can be created from scratch in a few minutes with very little training.

Standard Features in the software include:

1. Mortise and tenon

a. Thickness
b. Width
c. Depth
d. X axis placement
e. Z axis placement

2. Board dimensions (width and thickness)
3. Speed of cut (feed rate)
4. Two different tool paths to choose per operation (this gives flexibility to how the tool enters and exits the board)
5. Password protected edit functions
6. Save/Delete programs
7. Cycle counter
8. On screen graphical display of the Mortise and Tenon features

A Maintenance Screen gives you the ability to manage inputs, outputs and machine offsets.

From this screen you can manually trigger all outputs as well as visually see if the machine is seeing the inputs correctly. You also set the machine parameters that are not as communally used such as fence and spindle offsets from this screen.

Because this screen is password protected you can be selective with who you grant access to it.

installation and training

Installation & Training

One day of installation is included in price of machinery.

Customer Responsibilities:
1. Floor preparation per your needs.
2. All power supply connection per national and local codes and standards.
3. Any necessary pneumatic connections and supply.
4. Moving of the equipment which could require forklift(s), rigging, and labor.
5. Materials and tooling needed for machine testing, training, or adjusting.


The machine will ship fully assembled, and nearly functional. Pillar Machine expects the machinery to be in place, and all the necessary utilities to have already been brought to the machine before the technician arrives. The technician will finish preparing the machine to run and instruct any machine operators in how to maintain and operate the machine properly.

Should the machine not be ready at the time of the technician’s arrival, Pillar Machine reserves the right to charge up to $1000 for itinerary changes in the case of a complete cancellation of the installation, Pillar Machine will charge the full $1600 per day rate plus all travel expenses for the return visit.


Training should be attended by all individuals that need to understand how the machine functions including all Management personnel, Team Leaders, Operators and Maintenance personnel. If this machine is going in operation for multiple shifts per day, we suggest having all personal from those shifts attend this training session as well. If this is not possible and they need to be trained from the factory technician, please ask your Pillar Machine sales representative to add an additional day of training.


Notes: One day of technician time is defined no less than 6 hours on-site. The technician will spend the first few hours getting the machine setup correctly and the remaining time training.

If you have purchased a custom machine that has custom tooling you have purchased, make sure to have the tooling onsite and ready for installation, prior to the installer arriving. If we purchased the tooling, it will be on your machine. Have your samples ready for the installer.

The technician has planned the day(s) to install the machine and do any training of the machine as indicated in the contract. Having your appropriate tools and equipment needed to do the install and training will provide you and the technician a smooth install.
