Notes When Selecting the Tool Body

Modular Blade (1)

Select a modular blade for face grooving, so that the cutting diameter at the first pass is within the range of DAXN minimum and DAXX maximum that are described in the table of dimensions.

Modular Blade (2)

Select the shortest possible blade suitable for the application.

Modular Blade (3)

  • Select the largest size blade within the maximum cutting diameter of the workpiece.
  • Machine from the outer diameter towards the centre.

￬

  • Increased machining stability and rigidity is possible if a modular blade with the largest possible back metal is used.

At first machine the maximum cutting diameter, there is no restriction in the cutting diameter on the remaining process.

Modular Holder.

Modular Holder.

To ensure sufficient clamping rigidity, select a modular holder with the largest possible shank size.

Notes When Setting the Tool

Setting the Cutting Edge Height

Setting the Cutting Edge Height
  • Set the cutting edge height to ±.004" parallel to the central axis.
  • Cutting edge center height check should be done by traverse machining towards the center with a very small depth of cut and ensure that an even surface and no material remains at the center point afterwards.

When Intertering the Wall of Groove and the Modular Blade

When Intertering the Wall of Groove and the Modular Blade

If interference occurs even when the correct blade is used, the cutting edge height could be incorrect.

When interference occurs on the inner side of the blade, the cutting edge height is set too high.
When interference occurs on the outer side of the blade, the cutting edge height is set too low.

Set the insert parallel to the central axis.

Tool Overhang

Tool Overhang

When setting the tool, ensure that the overhang is as short as possible and avoid the step difference part as above figure shows.
