REV motorised slotter

1) Tool clamping screws
The tool clamping screws must be slightly unscrewed before correcting any symmetry errors. Before resuming the work, make sure you have tightened the tool clamping screws again.

2) Adjustable gib screws
After using the slotter for a long time, it will be necessary to eliminate the potential play created in the tool. Do this by unscrewing the hexagonal nut, tightening the centre screw and then screwing the hexagonal nut back on. Repeat this operation on all four gibs of the slotter.

3) Y-axis adjustment pin
This is used to correct any symmetry errors between the hole and the piece currently being processed. After unscrewing the tool clamping screws 1, turn the Y-axis adjustment pin either clockwise or anticlockwise. This will allow you to move the tool along the Y-axis. The adjustment range is +/- 0.5, which is extensive enough to correct all of the symmetry errors on lathes without a Y-axis.

4) Cutting angle adjustment screw
This screw is used to correct any conical errors due to mechanical bending. By turning it clockwise or anticlockwise the cutting angle can be changed by about +/- 3°. This range is sufficient enough to correct any conical errors.

5) Grease nipples
These two grease nipples are built into the external structure of the motorised slotter and are used to grease after about 10 hours of use, meaning the effective operating time of the tool (see example of calculation for greasing).

6) Threaded hole for internal 3/8” gas supply
All of the tools feature holes for the supply of coolant. The internal supply is recommended more than the external supply and allows the lubricant to be directed to the cutting area.

7) Alignment area
This is the area to be used for the comparator control.

8) Bolts clamping the slotter to the tool turret on the lathe
These are bolts that fasten the slotter to the tool turret on the lathe.



Mount the slotter onto the lathe. Slightly loosen the 8 clamping bolts and align the slotter using a comparator. The latter is to be placed on alignment area 7. When the slotter is perfectly aligned, tighten the 8 clamping bolts and operate the slotter at 150 movements per minute for about 10 minutes. Grease the moving slide with common oil for guides. This will soften the gaskets and break in the slotter before use.


To preserve the mechanics, we recommend greasing the slotter every 10 hours of use, meaning actual use (see example of calculation for greasing).
Preferably use Persian Poligrease EP 1.
Proceed as follows in order to introduce the right amount of grease:

  • Loosen the cap on the motorised cover;
  • Start introducing the greasing using the special grease nipples;
  • Stop the introduction of grease when it comes out from the hole;
  • Tighten the cap back on and start using the tool again.

Example of calculation for greasing
If 2 minutes are required to produce one piece and 10 seconds are needed to
make just the keyway for a feather key, grease after about 3600 pieces.


After a long period of use (about 1,000 hours), maintenance will need to be performed on the slotter, replacing the parts subject to wear such as bearings, gaskets, etc.


This motorised slotter can perform internal or external processing.
Simply reverse the motorised rotation direction as follows:
control M03 = internal processing
control M04 = external processing.
Depending on whether internal or external processing is to be done, the tool must be fixed with the insert following the cutting direction.


During the return phase, the tool detaches from the processed surface by 0.25 mm. This movement is essential to preserve the integrity of the insert.
