CMJ
Coping Machine
The CMJ is a machine designed for chip free coping or tenoning of either square or profiled parts without the need for a back-up piece or chip breaker. One motor with a belt is a great fit for smaller shops that don’t need to change between multiple profiles.
CMJ Advantages:
- No backer board or chip breakers required
- Tear out free parts every time
- Accurate spindle adjustment for tool alignment
- Part stays fixed while the carriage moves

CMJ Machine Description
Our coping machine provides a clean, tear-out free, end coped/tenoned part every time!
Pillar’s CMJ coping machine is designed to create end coping/tenoning for rail ends, as well as finger jointing or end matching – all in one machine. Incoming parts can be either square or profiled and require no backer block or chip breaker.
Standard Operation
The CMJ is manually operated with 2 counter rotating vertical spindles. One spindle clears the leading edge of the rail with the other spindle then moving in and processing the remainder of the components width. Cycle time for the CMJ is 6-8 seconds.
The machine uses a PLC control for simple and easy to use controls. The CMJ utilizes two (2) counter rotating vertical spindles. One spindle clears the leading edge of the rail (jump cope) then the second spindle moves in and processing the remainder of the component’s width.
The machine allows for two sets of profile tools to be installed at the same time. Switching from one to the other is as easy as a flip of a switch.
What the CMJ Does
The CMJ is typically used to perform the following operations:
- Shapes the tenoning joint of a moulding, door, or frame part.

Options for the CMJ
Pillar CMJ Additional Guarding Option
An additional rear guarding option adds to the machine with hinged access doors. The doors are made of tube steel and expanded metal.
Notes:
1. This option is a welded feature installed during manufacturing.
2. Selecting this option may increase your machines lead time.
3. This option does not include an electronic interlock.
4. When this option is used, it increases the depth of the machine to 40″.
Pillar Keyed Electronic Interlock
Keyed Electronic Interlock option gives instant switch access to the rear guarding hinged access doors and acts as an “Emergency Stop”.
Notes:
1. Photo may not represent the exact switch to be used on the machine.
2. Selecting this option may increase your machines lead time.
Pillar CMJ Foot Pedal Control
A foot pedal control option will convert the machine from a palm button start switch to a foot pedal start switch.
Notes:
1. Selecting this option may increase your machines lead time.
2. Photo may not represent the exact foot pedal to be used in this option.
Pillar CMJ 12-Inch Part Width Table Increase
The CMJs’ maximum width capacity will be increased from the standard 8″ to a maximum of 12″. This will allow the CMJ to accommodate wider components.
Notes:
1. This option will increase the cycle time of the machine by 20% because of the added amount of travel the carriage moves to accommodate the increased part width.
2. Selecting this option may increase your machines lead time.
Pillar Machine Automatic Oiler
Optional automatic oiler adds a compressed air automatic oiler to the frequently used bearings on the machine. The oiler uses oiled compressed air to deliver lubrication to the linear bearings. Because of the nature of this option, the bearings operate under positive pressure making them less susceptible to dust contamination.
Notes:
The oil injection amount can be adjusted using an adjustment knob on a pneumatic oiler at the machine.
The oiler will operate anytime the spindle is spinning.
The bearings that are oiled are:
a. 4 each X-axis linear bearings
b. 4 each under Drill spindle linear bearings
c. 4 each under Groove spindle linear bearings
Photo may not represent the exact oiling device to be used in this option.
Selecting this option may increase your machines lead time.
Pillar HSK Spindle Upgrade Option for the CMJ.
This option converts the machine from having one 5 HP spindle that belt drives two separate spindles to having two dedicated 11 HP HSK-63F spindles. HSK-63F spindles are very common in the woodworking industry and feature an electromechanical push-button quick-change operation. This is great if you have several different cutting profiles to use on this machine because it reduces the tool change time down to approximately 30 seconds. If this option is requested, Pillar Machine suggests that you ask for a specific CMJ-HSK quote as many of the features are different from the stock CMJ.
Notes:
1. All CMJ-HSK machines come with a standard 12″ table
2. All CMJ-HSK machines do not have a Z axis for stacked tooling
3. No tooling or tool holders are included in an CMJ-HSK
4. Please see a specific CMJ-HSK quote for exact specifications
