T indica la distanza dall’utensile al fi lo tagliente. (Quando si utilizza l’inserto bilaterale, con valori di T=20/25; causa interferenza, impostare la profondità al di sotto dei 18mm). 

La cota T muestra la máxima profundidad de ranura. (Si se usa plaquita de 2 puntas con el portaherramientas T=20/25, hace ranura por debajo de 18mm debido a interferencia)

Tips about external turning 

Point (I) (Traversing after grooving) 

1) Over 0.5mm of groove depth : For Roughing (Refer to fi g 1) 

Before traversing, pull the tool back by 0.1mm after grooving. 

(Put the load on edge from single direction.) 

fig 1 

Pull back the tool by 0.1mm 

before traversing 

(over 0.5mm of groove depth : 

For Roughing) 

2) Less 0.5mm of groove depth : For Finishing (Refer to fi g 2) 

Available to traverse continuously after grooving. 

(Dwell motion is not required) 

Point (II) 

1) In case of expanding groove width (Refer to fi g. 3) 

Please program to make steps at each pass. 

fig 2 

Traversing continuously after 

grooving 

(Less 0.5mm of groove depth : 

For Finishing) 

2) For fi nishing 

(Leave the material more than 0.5mm total to get bettter chip control.) 

Note; if machining without centering: 

If feeding the tool towards the tailstock, please reduce in this case 

the feedrate for more accurracy.

Tips about face grooving 

1) Toolholder Selection 

Check available Min and Max diameter as 

well as width and depth. 

2) Feed rate 

Set proper feed rate to form continiuous chips 

for steel machining. 

3) Expand groove width (Plunging, Traversing) 

Recommended traversing from outside to inside to get 

better chip evacuation.

4) Traversing 

A: ap over 0.5mm 

Plunging 

Pull back the tool by 0.1mm

When widening the groove width, apply the 

"Step Turning". 

The widened groove and side walls should be 

finished last

Traversing 

After plunging, traversing can start directly 

without pulling back.

Resolve breakage of edge caused by chips. 

·Doubled tool life by reducing damage on the 

edge. 

Results 

· KGDF + GM chipbreaker improved chip evacuatoin compared to B. 

(Resolved frequent breakage of holder.) 

· Smaller wear on the edge provided by MEGACOAT make the tool life longer. 

(Lower running cost by longer tool life)
