The MMTJ performs the following functions:

  • Mitering
  • Mortising
  • Tenoning

Standard Features:

  • 3-Axis control for high quality joints and flexibility in machining various sizes of profiles. (X, Y and Z)
  • 2 working zones
  • 3 HP high frequency spindle for mortise (18,000 RPM)
  • 6 HP high frequency spindle for tenon (18,000 RPM)
  • 1″ x 3.5″ machining capability (larger sizes available upon request)
  • 15″ industrial color touchscreen for creating and selecting programs

Advantages of The MMTJ:

  • Elimination of complicated machine setups climb cut of both tenon and mortise cuts for a “tear out” free cut.
  • The ability to cut MDF paper or vinyl wrapped profiles.
  • Eliminates the need for applying inlays.
  • Reduces the maintenance and cost associated with the tooling by more than 50% by eliminating end coping.
  • Eliminates the need for outside profiling or sanding the edges of doors
  • Eliminates the need for sanding the face of the doors
  • Both stiles and rails are run face down for consistency of machining.
  • Self aligning joints
  • There is a more durable and aesthetically pleasing blind joint (no visible joint on edge of board)
  • Multiple tool paths to choose from in tenon and miter (on the mortise side) to accommodate all profiles.

MMTJ Software:

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 less than one minute with very little training.

The software will control:

  • Mortise and tenon size independently
  • Speed of the cut
  • Number of passes required
  • Start point of the mortise/tenon
  • Center point of the mortise/tenon
