Machining Guidelines

для размещения заказа - zakaz@widiahanita.ru

Machining Guidelines for Chip Control • Grooving

When the proper cutter diameter is not available, proper cutter

positioning will provide positive results.

• Centre height of insert should be positioned at the centre

of the workpiece or up to 0,13mm above.

• Dwell time in the bottom of the groove (more than three revolutions)

is not recommended.

• Chip control is feed-rate related and should be adjusted to fit the

particular situation. Recommended feed range is 0,08–0,3 mm/rev.

Machining Guidelines for Chip Control • Turning/Proling

Maximum depth of cut for side cutting (turning/profiling)

depends on the material being cut and the width

of the tool.

• 0,79–1,6mm wide insert

can cut up to 0,6mm deep.

• 1,7–3,3mm wide insert

can cut up to 1mm deep.

• 3,5–4,8mm wide insert

can cut up to 2mm deep.

• 5–6,35mm wide insert

can cut up to 3mm deep.

Finish Turning the Groove

1. Plunge both sides of groove width.

2. Plunge centre area to remove web of

material remaining.

3. To avoid insert chipping and to achieve groove wall

perpendicularity, follow the tool path outlined.

4. Use the lightest depth of cut that still allows

good chipbreaking, tool life, and surface finish.

NOTE: The same maximum groove depth and minimum bore diameter values also apply

to metric, NG-K (chip control), and NR (full radius) inserts of similar size.

The same internal grooving depth limits are a function of bar clearance versus

bore diameters.
