WWX Series

High Rigidity and High Quality Performance

The “X-Type” insert shape achieves both high quality surface finish and economic efficiency.

The insert’s main cutting edge can machine a 90° wall surface. Additionally, the large R-wiper edge is adopted for achieving a good surface finish, while, the optimised “X-type” with 6 corners contributes to lower tool costs.

The generous thickness of the insert provides high rigidity.

The new WWX200 insert is 1.5 times thicker than a conventional ASX400 insert, and the WWX400 is 2.2 times thicker. This extra thickness provides higher rigidity and fracture resistance.
Additionally, the extra rigidity eliminates the need for a seat shim.Therefore direct clamping of the insert to the body provides extra stability.

Excellent control and chip abrasion prevention.

CAE* analysis was used for the main cutting edge design. This resulted in changing from a straight to a curved cutting edge. Further, the rake angle shape of the optimised cutting edge greatly suppresses the scattering of chips to the bottom surface and outside periphery surface. This provides a good finish surface and markedly improved efficiency.

*CAE : Computer Aided Engineering

The optimised insert support and high clamp rigidity improve stability.

The conical shaped seating surface widely supports the insert seating surface while the radial geometry of the tool body behind the insert provides necessary clearance to suppress body damage from scratches and chip abrasion. Additionally,the strong clamping force of the screws prevents loosening to provide robust clamping.

Low cutting resistance suppresses chatter vibration even for thin workpiece materials.

Although a double-sided insert type with an axial rake angle of 9°(close to that of a single-sided insert type) is used,the WWX400 insert achieves lower cutting resistance than a single-sided insert (in-house comparison) and suppresses chatter vibration when machining thin workpiece materials.

Variety of cutter types, diameters & pitches.

Increasing the insert thickness, while achieving seat-less clamping made it possible to incorporate a large number of teeth while maintaining large chip pockets to provide a variety of cutter options.
A standard inventory is maintained consisting of 3 pitch types of both arbor and shank type cutters of same diameter.
Fine pitch types in particular allow a high table feed and greatly improve efficiency.
