1 Keeping the Customer First Tungaloy Report No. 369-E 369-J Proiling inserts The New Y-Pro Series o Inserts or Proiling

2 A new concept in proiling! Inserts with a 25 corner angle to expand machining possibilities!! (Patent Pending) Negative type type VNMG / VBMT Y-Pro series This angle reduction contributes to reducing customer costs Suitable or a wide range o machining applications The new Y-Pro series expands the machining range o Taper cutting, undercutting and "V" grooving applications. Negative Spherical proiling Enlarged clearance expands the intererence avoidance area. Negative "V" grooving Suitable or various "V" grooving applications θ 30 Face proiling Allows drastic productivity and capability improvements 2 a p Comparison o undercutting capability Reduced tool intererence ød (min) θ 30 External undercutting Allows a range o undercut orms to be machined Y Pro series / YWMT type Corner R ap (mm) ød (mm) ø10 ø ø15 ø ø ø26 Internal undercutting and proiling Allows undercutting o small diameters. Corner angle 35 / VBMT type Corner R ap (mm) ød (mm) 0.5 ø ø ø ø55 Improves the capability o small diameter machining!

3 Negative YNMG type Extremely capable and lexible insert YNMG inserts are applicable or existing external and internal toolholders. The Y-Pro series improves the application range or under cutting, V-grooving and taper machining. Same toolholder or both inserts Conventional VNMG 35 type YNMG 25 type For details and compatibility with toolholders, see "Instructions or use." When using competitor toolholders, the applicability should be checked in advance. Corner radius 0.4 mm 6.1 mm Corner radius 0.8 mm 4.7 mm 25 YWMT type - or a variety o machining processes External toolholders Vastly reduced tool intererence in acing and undercutting. Cut away portion Internal proiling Compared to the 35 positive insert, the 25 insert can work with smaller bore diameters. Tapered portion Internal toolholders By using the specialized "Stream Jet Bar" series o boring toolholders, excellent chip evacuation is guaranteed with its internal coolant supply.

ZFchipbreaker For inishing Negative insert High and broad chipbreaker High and broad chipbreaker wall are ormed near the corner point. Well controlled chips.

Improved seating stability ZM chipbreaker For medium cutting Inclination The side rake angle is increased in the direction o the arrow. When proiling, chips are curled and broken.

The hemispherical protrusion improves chip control. When high eed and large depth machining, the chips are controlled by the rear wall.

Well controlled chips. 25 Stable insert seating Suicient boss ace is ormed along the insert outline. Improved seating stability ZM chipbreaker For medium cutting Inclination The side rake angle is increased in the direction o the arrow. When proiling, chips are curled and broken. When undercutting, chips are evacuated smoothly. Hemispherical protrusion and chipbreaker wall A hemispherical protrusion and high wall have been introduced. The hemispherical protrusion improves chip control. When high eed and large depth machining, the chips are controlled by the rear wall. 25 insert Dimple structure Dimples are ormed near the corner point. This reduces the contact area between the chips and the rake ace, reducing thermal cracks.
