A few months ago during Westec, we had a chance to talk to applications engineer Bailey Stump with Marubeni-Citizen Cincom about new capabilities on its flagship Swiss-style lathe, the L20XII ATC (Automatic Tool Changer).
As highlighted in the video above, the ATC tooling with a fully programmable B-axis can be mounted on the gang tool post, enabling a total of 13 B-axis tools (12 ATC tools and one built into the tooling).
The ATC’S tool setting allows for several types of workpieces to be completed in a single setup and used in a wide range of applications — especially parts that require a lot of cross/end face machining. These can include difficult-to-machine components requiring secondary operations like finishing and deburring, components APMT Insert requiring multiple live tools, as well as rough and finish cuts that can be split between multiple tools.
Stump also says that having 13 total tools mounted to the b-axis opens up options for the manufacturing engineering team to get complex or difficult-to-machine parts off the machine fast feed milling inserts complete, minimizing part handling.

The new Edge2 DSS system from Dapra is designed to deliver both 90-degree milling performance and good value for an indexable milling product. Double-sided DSS inserts provide four usable cutting edges to lower cost per edge versus single-sided inserts. Additionally, Dapra’s permanent automatic cutter replacement program is intended to make it easier for shops to keep good-condition tools deep hole drilling inserts in use rather than making do with worn-out cutters.
The inserts feature a positive geometry for low cutting pressure and maintained strength. Convexity creates smooth surface finishes during step-down profile milling, and a custom-designed wiper edge generates good surface finishes, the company says. These inserts are available in both T-land and dished geometries in a variety of high-performance grades and coatings.
DSS end mills, shell mills and screw-on modular WCMT Insert heads are machined from hardened, high-shock tool steel to minimize runout and maximize durability and life. Nickel plating provides a harder casing for improved pocket durability and resistance to chip galling, while deep gullets deliver efficient chip evacuation, even on the heaviest cuts, the company says.

Kennametal’s KBH10B and KBH20B grades, designed for hard turning, are available in double-sided inserts for materials as hard as 65 HRC. The polycrystalline cubic boron nitride (PCBN) grades are specially designed to deliver higher productivity and longer tool life when turning tool steels and other hardened materials, according to the company.
Robert Keilmann, turning product manager, says that the inserts are ideal for "high-volume production of hardened gears, shafts, bearings, housings and other drivetrain components, where tooling cost per part is an important metric.”
Various features are said to surface milling cutters make the PCBN mini-tipped inserts cost-effective for turning hardened steel components. A ceramic binder structure and TiN/TiAlN/TiN coating provide extreme wear resistance even at elevated cutting speeds, the company says. A gold PVD coating makes it easier to identify when an insert needs indexing, while the numbered corners ensure that a machine operator does not inadvertently switch to a used edge. Two edge preparations in a "trumpet-style” hone the inserts for heavier and interrupted cuts, while a light hone prepares the inserts for continuous turning. Both inserts are free-cutting, extending tool life and generating surface tube process inserts finish values as low as 0.2 Ra. The PCBN mini tips are offered in four insert shapes — three rhomboidal and one triangular — which provide up to six cutting edges per insert.

Roll into the cut by following an arc that curves in the same direction as the tool rotation. This keeps the chip thin at the end of each cutting edge pass.
"It’s better to burn out than fade away.” Both Neil Young and Def Leppard sang this. Neither of JDMT Insert them could have been talking about cutting tools.Shops want their cutting tools to "fade away.” That is, they want them to go through gradual, predictable wear. They don’t want them "burning out” in the form of a sudden, surprising failure. Even so, shops routinely (and unknowingly) subject tools to brief moments of intense strain that make the burnout a danger.An example can be found in the way end mills often enter the material. Climb milling helps a carbide tool by enabling the chip thickness to proceed from thick to thin with each cutting edge pass—relaxing the load on the cutting edge gradually so there is no "springback” at the end of every pass. However, when the tool enters the material in a straight line, there is a brief period during which the full thick-to-thin Cemented Carbide Inserts progression has not yet been realized. During this period, the cutting edges are springing. Tests conducted by Sandvik Coromant show that just this brief span of time can cost the tool most of its potential lifeThe cutting tool maker offers this solution: "Roll” into the material. Feed the tool along an arc that keeps each cutting edge experiencing thick-to-thin chip formation from the very beginning. The technique is one of the recommendations given in this article: Let the Tool Path Help the Tool.
