Single & Double End Tenoners, Sizing Machinery

Single End Tenoner

The Mereen-Johnson Single End Tenoner is a panel raising machine and cabinet door profiling machine in one — a 900 Series push through tenoner built for high-precision raised-panel door production. Each part loads into a fixture and is carried through the machine under positive containment, so this raised panel door machine holds tight tolerances on every cope, profile, and raised panel — whether you’re running to order or in small custom batches, in wood, composites, or other materials.

Our Tenoners are designed for high production runs while simultaneously providing the flexibility of variable sizes & small-batch runs. Ideal for panel raising, outer door profiling, contouring, & much more. Whether you work with wood, composites or other green resources, Mereen-Johnson Single-End Tenoners are up for the task.

How the 900 Series Push-Through Tenoner Works

The 900 Series is a push through tenoner: instead of feeding parts loose through the machine, each part is held in a fixture and carried through the machining stations under positive containment — which is what delivers greater precision than feed-through machines.

Contain the part. Air-actuated part containment, interlocking urethane hold-down blocks, and Mereen-Johnson’s exclusive servo-driven leading-edge alignment pins lock each part squarely to the feed — so it can’t shift, run to run.
Square & size. RH and LH servo-controlled pins stop work in tandem to square the part, with a programmable RH guide for precision sizing.
Machine the profile. Precision Multi-Vee feed chains carry the part past high-speed profiling copes (with lower support anvils for clean corner blending), rail-shaping and edge-profile stations, and variable-speed dual wheel sanders that counter-rotate for an optimum finish.
Run a CNC program. A touch-screen CNC control measures each panel and runs the operations automatically — including auto-generated arch, cathedral, flat-top, and eyebrow contours from simple dimensional input.

Because the part is contained in a fixture rather than fed through loose, a push-through tenoner holds tighter tolerances on visible door faces — the reason it’s the preferred approach for raised-panel cabinet doors.

Raised-Panel Doors & Cabinet Door Profiling

As a raised panel door machine, the 900 Series runs the full cabinet-door sequence under CNC control:

Measure the panel. The control measures each panel’s width and centers the program automatically.
Hog the contour. CNC-shapes the panel top — square, arched, cathedral, flat-top, or eyebrow.
Raise the panel. CNC edge-profiling raises the panel field to your chosen profile.
Shape the rails. The rail-shaping station copes and profiles the frame parts to match.
Profile-sand. A long belt profile-sands the straight sides of panels for a finished surface.

From square-raised doors to arched and cathedral styles, the machine builds consistent raised-panel doors and profiles cabinet-door frames to match — automatically, part after part.

Applications

Beyond raised-panel doors, the 900 Series handles a range of profiling and tenoning work:

Panel raising — raising panel fields to profile, including arched and cathedral tops.
Cabinet door profiling — coping and shaping door frame rails and stiles.
Contouring — arches, cathedral, flat-top, and eyebrow shapes from dimensional input.
Mitering — optional miter fixture tables with up to 50° angle capability.
Wheel sanding — dual, counter-rotating variable-speed heads for a finished profile surface.
End tenoning & component profiling — precise machining of frame and furniture components.

As a cabinet door profiling machine and panel raising machine in one, it consolidates several door operations into a single, CNC-controlled station.

Industries Served

The Single End Tenoner supports precision profiling across:

Cabinetry — raised-panel cabinet doors and face-frame parts.
Doors — outer door profiling and panel components.
Furniture — profiled and contoured frame components.
Windows — frame component machining, with heavy-frame precision.
Custom Millwork — arched, cathedral, and custom-profile parts.

Emerging applications: composite and engineered materials — the machine runs wood, composites, and other materials on the same platform.

Frequently Asked Questions

What is a single-end tenoner used for?

A single-end tenoner machines one end or edge of a part — tenoning, coping, profiling, panel raising, and contouring. The Mereen-Johnson 900 Series is built especially for panel raising and cabinet door profiling.

What is a push-through tenoner?

A push-through tenoner holds each part in a fixture and carries it through the machining stations under positive containment, rather than feeding parts loose. Fixture containment and linear-rail construction give it greater precision than feed-through machines.

Can it make raised-panel cabinet doors?

Yes. As a raised panel door machine, it runs the full CNC sequence — measuring the panel, hogging the contour, raising the panel field, shaping the rails, and profile-sanding — including arched, cathedral, flat-top, and eyebrow styles.

What door and panel shapes can it produce?

It auto-generates standard arch, cathedral, flat-top, and eyebrow contours from simple dimensional input, and measures each part to center the program.

How does it hold tolerance across a production run?

Exclusive servo-driven leading-edge alignment pins, RH and LH servo pin stops, air-actuated containment, and interlocking urethane hold-downs lock each part square — so the cut repeats regardless of run length.

Can it cut miters?

Yes — with optional miter fixture tables that provide up to 50° angle capability.

What materials can it run?

Wood, composites, and other materials, in high-volume runs or small custom batches.

Is it made in the USA?

Yes. The Single End Tenoner is designed and built by Mereen-Johnson in the USA, and can be integrated with moulders and automatic transfers as a single-operator work cell.
