Machine Features:
The Laguna DT18 Dovetail machine creates perfect dovetail joints effortlessly at a production rate of approximately
40-50 boxes per hour.
Dovetail joints are widely recognized as one of the strongest and most durable joints in woodworking and add value
to users’ cabinet jobs.
This machine cuts the pins and tails separately or at the same time to speed up production. Individual pneumatic
clamps allow users to cut two joints in one pass or to work on wide panels for furniture.
The collet chuck makes bit changes fast and easy and increases cutter life. Adjustments are read on individual
scales for quick, repeatable setups.
The centralized control panel makes the operation easy and automatic; the operator just needs to load the parts
and start. This machine is assured to increase your profits and productivity.

Operation 17
Operation
Adjusting the Height of Male Indent:
A1.) Adjusting the Height (H) of Male Indent
Loosen Screw (B) and then Adjust Shaft (C) could move the Spindle (A) in a Up/Down-Ward motion.
When you are adjusting the height, you must notice the Height of Cutter head (D), to avoid the cutter head to
against the board.
Make sure to position the milling cutter on the
bottom of the spindle when adjust the height of
workpiece. Failure to comply with this may result
in damage of drill bit and positioning frame.
A2.) Adjusting the thickness(s) of male indent. Move the Mold (A), to positioned to the limited back. Take off the
Cover, Loosen the Screw (B), Adjust (C) with Hexagonal Wrench ,
then tighten the cover.

DT-18 DOVETAIL18
Do not move the red arrow below zero--the bit and
located magazine will break.
A3.) Adjusting the Female Indent Depth (S1) Position the support of chaser to the origin. Loosen the 2-Two
Wrenches (A) for adjusting (B) to the desired depth. Tighten the wrenches finally.
A4.) Adjusting the Highness of Clamping.Rotate Nut (B) for adjusting the highness of Actuator Assembly (A), to fit
the wood piece thickness.
A5.) Adjusting the position of workpiece Decide the position of cutter workpiece first. Position the Horizontal and
Vertical Fixture the Screw (C). Please note that to match the front and side edges of the drawer, these two
workpieces must be different in the height by half a pitch. (For example, the Pitch=25 MM, the
difference=12.5MM).

Operation 19
A6.) Fully/ Half return Cutter Adjustment:
1.) The machine cutter stroke has two kind, fully or half stroke. It is referred to the wood length to selection.
2.) Long wood set fully return cutter, short wood set half cutter return, to save the nonworking time, to improve the
speed.
3.) The return of the cutter was set by the stroke block. Block touch the limited switch (1) during feeding, the cutter
returns to home.
4.) Set fully cutter return instruction: Loosen the screw on the sensor block, turn the block to the surface force
inside, the block cannot touch the limited switch (1) during feeding, the cutter can run fully stroke then back to
home.
5.) Set half cutter return instruction:
Loosen the screw on the sensor block, turn the block to the surface force down (as photo shows) during feeding,
the block touches the limited switch (1) , then the cutter back to home.
The cutter return can set on A of located magazine, it improves the speed in making small wood. Move the cutter
to position (A), Loosen the Limited Block (D), to the position to touch limited switch (C), stop auto return cutter
and back to original position, notice to correct position on (A), to avoid the cutter hit the located magazine to
damage.
Air returns to home automatically, retract the tenon
cutter can not set at position B to avoid the cutter

DT-18 DOVETAIL20
damage; correct the retract cutter, correct the
mortise position again.
A7.) Adjusting the Wind of Cutter returned speed Adjust the Regulator (A) to reach the desired speed.
A8.) Adjusting the return speed of copy shaft Adjust the Regulator (A) to reach the desired speed.
The return of the copy shaft should be kept
adequately slow.
