Walter optimises grooving, parting with Walter Cut SX

?With the new flexible Walter Cut SX tool system, Walter AG has optimised grooving and parting off, and at the same time, reduced the number of cutting inserts required. These can be used both on lathes for grooving applications and on milling machines for separating and slot milling.

Process reliability is required for grooving and parting off, especially when the tool has to cut deeply into the work piece. The new Walter Cut SX grooving system meets this requirement particularly well with its single edge grooving inserts. As a reminder: When inserts with two cutting edges are used, the cutting depth is limited according to the insert length. Some industries, however, increasingly require very deep grooving and parting-off cuts. For such applications, the developers created the SX system with completely new self-clamping, single edge grooving inserts. Their particular feature is positive-locking integration in the tool insert seat, which is achieved through their curved shape. This positive locking prevents the cutting inserts from being lost when under heavy load in the direction of feed.

The self-locking system is also based on a new design. The top clamp is capable of producing extremely high retaining forces without hindering the chip flow. It fixes the cutting insert in the tool insert seat, which takes the form of a prism for precise insert location. In addition, the insert seat also has a contact surface at the back for supporting the cutting insert. As a result, the cutting forces are transferred into the fixed part of the tool. This ingenious distribution of force guarantees excellent process reliability and enables an increase in productivity thanks to higher cutting parameters. The user is provided with a special key for changing the insert, which allows replacement in just one simple operation.
