Grooving Tool

Highly reliable insert clamping

New Tri Lock System for increased stability and performance!

aSafety keys prevent insert movement.aThe convex geometry ensures high precision clamping.

GY series offers ultimate rigidity and accuracy for stability when grooving.Easy to use modular blade system allows flexible tool management but maintains an overall strength comparable to a mono block type holder.

Mitsubishi Materials has developed an original and unique, new modular blade system.*The Tri-Lock system ensures the blade is securely fixed in 3 directions (side, front and top) giving high rigidity for stable grooving performance.

The TRI-LOCK system gives excellent performance in comparison with conventional modular type holders.

The front locking gives improved surface finishes even when cross-feed machining.

The TRI-LOCK system offers the best performance even when cross-feed machining.

Unique dimple technology for dampening vibrations. Twin coolant for smoother machining.

In comparison with conventional modular types, vibration and insert movement are eliminated resulting in higher quality surface finishes.

*1 The maximum groove depth changes according to the insert used. Please refer to the maximum groove depth of inserts on pages 9 and 10.

*2 The maximum cut off diameter D1 changes according to the insert used. The cut off diameter is double the maximum groove depth (ar) of inserts on pages 9 and 10.

*3 Dimensions shown are when the gauge insert is used. If other insert geometries are used then L1, L2 and F1 values may vary.

*4 The maximum groove depth is limited by the workpiece diameter. For details, please refer to page 22.

Roughing Finishing

Finishing Precautions when Finishing Walls

Machining of a Ring Section

It is recommended that cross-feed machining is used.It is recommended to carry out plunging in several passes.Following the steps above makes it difficult for chips to elongate.This also improves the accuracy of workpiece wall surface.

Machining Narrow Grooves Machining Wide Grooves

Wall Machining

Machining Wide Grooves

When machining a wall, chip jamming can occur. In this case, stop cross feed machining just before the wall (at a point less than the insert width) then remove the remaining material by plunging.

When a ring remains in a cross feed end process, finish cross feed machining 1–1.5mm short of the end point, then remove the ring by plunging.

,Machining of the wall surface, corner radius and bottom face should be carried out in one process.

mCarry out grooving to the end point of the corner radius.

zCarry out grooving.xRetract the tool

approx 0.1mm.

.Stop at the bottom of the corner radius.

/Machine the counter wall to the corner radius in one process.

To produce high accuracy walls using MS or MM breaker insert, do not carry out back turning. Plunging is recommended.

cCarry out cross feed machining.

vRetract the tool approx 0.1mm.

bCarry out grooving.nRetract the tool approx

0.1mm.* Repeat the steps z–n .

Finish machining.

Finishing

With the BM breaker insert, 3 dimensional copying is possible.Set the depth of cut (ap) to 40% less than the insert width.

Carry out finishing in one process.For the depth of cut (ap) when back turning, refer to the table on the right.

Use plunging and cross-feed machining.When machining the corner, vibration is likely to occur. To avoid this, reduce the feed by 50%.

aNotes for cutting off

When the cutting edge approaches the centre, reduce the feed by 50%.

If necessary, stop the feed prior to reaching the centre of the workpiece to prevent it falling under its own weight.

When using constant cutting speed during a cutting off cycle, it is recommended to limit the spindle speed to 80% of maximum to ensure stability.

To prevent the workpiece from being expelled, lower the spindle speed before finishing the grooving operation.

When there is a centre stub on solid bar work or burrs are formed on pipe material, it is possible to decrease them by using a handed insert. With a handed insert, machining tends to be less stable when compared to using a neutral insert. Pay special attention to avoid fracturing of the cutting edge and decrease the feed when necessary.

For a ø40 shank holder, if there is no restriction for use, select a holder suitable for GYM25 blade.

When the overhang is the same, select a holder with the largest possible shank size to ensure sufficient clamping rigidity.

The maximum groove depth is limited to the dimension L3. When machining with longer overhangs, refer to the dimension F2 of the tool used.

Chips

Coolant

aWhen the cutting edge width is x 2 < groove width

Apply a large amount of coolant to the cutting edge for effective chip disposal. Also, apply coolant continuously until the tool comes completely away from the workpiece for improved chip disposal.

As continuous chips tend to elongate at the back of the bore, the above operations is recommended. The recommended width of cut for x is 0.5mm.

When the groove depth is larger than the cutting edge width, carry out plunging in the steps above to break chips efficiently.

When the depth of cut is narrower than the cutting edge width, continuous chips are usually produced. When plunging in several passes, it is recommended to carry out machining in the steps above. This ensures that coolant reaches the cutting edge and chips are easily discharged.

When chip breaking and disposal are especially important, cross-feed machining is recommended.

It is recommended to carry out grooving from the front end of the workpiece. This makes it possible to reduce workpiece deflection.

The first recommended steps are the roughing steps on page 34.

If the groove depth exceeds a given level, chips may elongate at the wall. In such a case, increase the feed and carry out machining as shown above.

For internal grooving, the machining methods for external grooving (P32 – 33) can be used, nevertheless it is necessary to take precaution to the following.
