The latest modular parting blades from ARNO take a very practical problem on the shop floor and solve it with additive manufacturing rather than incremental geometry tweaks. The goal is simple – get more coolant to the cutting edge, faster and with less restriction, under real production conditions.

Traditional modular parting blades rely on cross-drilled coolant holes. Those passages intersect at right angles or shallow angles that disrupt flow, reduce velocity, and create pressure losses before the coolant ever reaches the insert. In difficult materials or deep part-off operations, that restriction shows up quickly as heat buildup, edge breakdown, or chip welding.

By moving to 3D printing, ARNO eliminates those intersecting drill paths entirely. The internal coolant channels are formed as continuous, smooth passages that run directly from the adaptor interface to the insert pocket. There are no abrupt direction changes, no dead zones, and no compromises driven by drill accessibility. Coolant reaches the cutting edge with higher volume and more consistent pressure.

A key detail is the flank coolant outlet geometry. Instead of a round port dictated by drilling, the 3D-printed blades use a triangular flank port. This shape spreads coolant across the insert edge and into the chip formation zone more effectively. The result is better heat extraction at the point of cut, improved chip evacuation, and a more stable thermal condition during the cut.

These blades are offered in both ARNO-specific mounts (MSA-S) and industry-standard mounts (MSA-I), making them a drop-in upgrade rather than a system change. From the operator’s perspective, setup and programming remain the same. The difference shows up in tool life, surface finish, and process reliability.

In practical terms, improved coolant delivery translates directly into more parts per edge and fewer interrupted runs. Shops running stainless steels, superalloys, or long cycle part-off operations will see the most immediate benefit, but even in carbon steels the added thermal control helps maintain edge integrity and dimensional consistency.

Identification is straightforward – ARNO designates these tools with a “-3D” suffix in the part number. That small detail signals a fundamentally different internal design aimed squarely at process stability rather than marketing flash.

For shops that already rely on modular parting systems, the ARNO 3D-printed blades address one of the most common limiting factors in parting and grooving operations. More coolant at the edge means lower cutting temperatures, more predictable tool wear, and fewer surprises in unattended or high-mix production environments.

WhizCut developed the WhizFix 2.0 system to address a familiar problem on Swiss-type lathes and compact turning platforms—tool changes that interrupt flow, consume setup time, and introduce inconsistency. WhizFix 2.0 approaches this problem with a modular quick-change holder that maintains the rigidity and accuracy expected from a solid toolholder while significantly reducing changeover time.

The system is built around a compact dovetail interface that allows insert heads to be exchanged directly on the machine. Locking and unlocking requires only a short rotation, with low torque values that reduce wear on both the holder and insert head.

Once locked, the insert head repeats its position consistently, eliminating the need for touch-offs after routine changes. This repeatability supports stable dimensional control across longer production runs.

WhizFix 2.0 maintains a short distance between the insert tip and the holder plate, which improves cutting stability and supports finer surface finishes. The holder geometry is intentionally compact, making it well-suited for machines where tool clearance and gang spacing are critical. Despite its modular design, the system performs with the stiffness typically associated with one-piece holders.

The system is offered in a range of configurations to support common Swiss turning operations, including turning, grooving, and profiling. Insert heads can be shared across compatible holders, reducing overall tooling inventory while increasing flexibility at the machine.

WhizCut's WhizFix 2.0 fits well into production environments where uptime, repeatability, and quick changeovers directly affect throughput. That's a marketing line that pretty much identifies anyone running a swiss machine shop. And in this particular case, its jsut true.   WhizFix 2.0 delivers in setup efficiency without adding complexity to the process, making it a practical upgrade for every swiss machine.

Fine-tune your way into the future of backworking, with WhizAdjust, an adjustable toolholder system from WhizCut!

Take back working to a new level with Whizcut WhizAdjust and enjoy the flexibility. This is an innovative and patented toolholder system that is perfect for turning against the sub spindle. The height adjustment goes quick and easy - without loss of stability.

The quick: The fine-tune adjustment screw together with stable clamping makes it possible to modify center height. Loosen one clamping screw from the WhizAdjust head and shank - and the adjustment is done. It is as easy as that.

The stable: The shank and adjustable head are positioned together with serrated surfaces in X axis and the adjustment screw plus a spring in Y. The repeatability, by removing the toolholder and fastening it again, is under 0,005. ​
