Reverse-side tools for automatic lathes

The new, innovative reverse-side tools score points in terms of stability, set-up time reduction, space requirements and optimum coolant supply. The tools are used for machining operations on the secondary spindle and can switch one or the other machining operation to the back of the component. This can still save time even in well coordinated processes.

Due to the well-designed tools, every set-up position can be used on the usually narrowly designed tool comb. Care must be taken to ensure that there is room for the component between the tools during machining. Our interchangeable tool holders with height adjustment are particularly interesting. They are suitable for machines without a Y-axis or also for small series with frequent machine changeovers.

All the advantages of reverse side machining at a glance:
  • Speed: Ultra-fast tool change by tightening / loosening just one bolt
  • Flexibility: Flexible on all machines → base holders are installed in the same way on all machines and remain in the machines
  • Precision: Most accurate height adjustment possible
  • Set-up time optimisation: Presetting via an adjustment screw directly in the machine or externally in the presetting device
  • Cooling: Optional coolant overpressure by attaching a coolant attachment

Setting Device

The setting device allows you to adjust our modular holders to the correct height outside the machine, gaining flexibility and time.

All the advantages at a glance:
  • Set-up time optimisation through convenient presetting outside the machine
  • Avoid machine downtimes
  • Best positioning accuracy after tool change due to presetting outside the machine

The adjustment device is profitable if the tool system is expanded with several tool holder blocks on several machines. The tool system can be preset so that holders on every machine have a suitable centre height in relation to the turning centre of the machine.

Zero the dial gauge on the surface of the measuring stick.

Place tool holder block on the device and gently tighten the clamping screw until the holder sits on the device free of play. Ideally, set the centre height slightly below the centre, so that the tool holder block is pushed upward when the height is set.

Carefully place the dial gauge on the tip of the tool’s cutting edge.

Adjust the height adjustment screw until the dial gauge is set to zero.

Procedure when retrofitting on our tool system

  1. Screw all base holders (1) into the machine.
  2. Clamp the height-adjustable screw (4) of the individual base holders (1) and set to the same height using the dial gauge.
  3. Clamp a tool holder block (2) onto any base holder (1) and set precisely on the turning centre using the height-adjustable screw (3) of the tool holder block (2).
  4. Remove the tool holder block (2) from the machine and clamp it on the height presetting device.
  5. Set the dial gauge on the tool to zero and adjust the measuring pin on the presetting device.
  6. Each additional tool holder block (2) is set to zero once on the presetting device using the measuring pin and dial gauge.

If several tool holders are arranged side-by-side, you can quickly and reliably fix them at the same height using height adjustment screws (3) and (4).

The same tool holders (2) can be used for multiple machines without presetting them again individually. However, the base holders (1) of the other machines must be adjusted to one another.

This is done as follows:

  1. Screw all base holders into machine 2.
  2. Clamp a preset tool block holder from machine 1 on any base holder in machine 2 and adjust the turning centre precisely using the height-adjustment screw of the base holder.
  3. Set all other height-adjustable screws on the rest of the base holders in machine 2 to the same height using the dial gauge. The preset tool block holders can thus be used on each tool station of several machines without readjustment.
