Inserts & Tool Bits

The global manufacturer has added five variants of square shaped positive inserts for depths of cut up to 6.4 mm to its Pramet brand. The range is suitable for a variety of general engineering and maintenance and repair operations (MRO) machining, with several application-specific geometries and grades available for machining any workpiece material.

ARCH Cutting Tools Marketing Director Rachel Dresser took time during Eastec 2023 to highlight the company's product series for KEO, Ultra-Dex, Patriot High Performance, and Revere, as well as its RECON360 remanufacturing service.n

The Greenleaf Corp. ran a demonstration at its booth during Eastec 2023 showcasing the capabilities of a range of tool, including indexable and solid options. Included in the demo were Greenleaf's Ring Max tool and its XSYTIN-1 phase-toughened ceramic insert grade. n

The inserts feature three cutting edges at a 50° copying angle. Compared to the WL25 indexable inserts, which measure 25 mm per side, the WL17 inserts measure 17 mm per side. The WL25 inserts are now additionally offered in W0110-C Walter Capto tools and the W1211 QuadFit exchangeable head for Accure.tec anti-vibration boring bars.

DoMultiRec multifunctional milling cutter with center cutting capability enables a single tool to perform multiple milling operations, including shouldering, pocketing and drilling. A uniquely designed insert integrates a center and peripheral cutting edge on one side of the insert; the same insert can be used either for the center or peripheral position for up to four indexings per insert.n

The HM geometry has a highly negative and narrow T-land, as well as a positive rake to reduce vibration and enable a smoother cutting action. Together, these improve the durability and process security, prolonging tool life in the relevant materials by up to 50%, compared to the existing assortment.

The WKK25G grade is a true specialist when milling today's cast irons (ISO K material group), such as ductile cast iron. Specifically, the grade is ideal for unfavorable milling conditions, such as interrupted cuts, and for wet machining applications. The grade meets the most stringent requirements for process reliability, particularly in the automotive industry, and is suitable for highly abrasive workpiece materials.

The peripherally ground insert offers improved wall accuracy and straightness and creates a true 90° corner. The LNEX12 also featuring a patented U-groove segment on all four cutting edges which provide a good surface finish and expand its application range to low-power machines and small depths of cut. In addition, the two-sided design supports performance by making ramping possible.

Ideal for holemaking without a pilot drill up to 10×Dc, the inserts provide time savings that boost productivity. The inserts were designed to achieve maximum tool life in stable machining conditions thanks to the wear resistant WPP25 grade with HIPIMS technology. The grade has a particularly hard and robust substrate to extend tool life.

When using indexable inserts, employ fine adjustment cartridges made for the 21st century.

The latest Pramet range includes three variants of a 16-edged ONMX insert for depths of cut up to 0.157" (4mm). The standard geometries include the F for light operations, M for versatile use, and R for rough cuts in a variety of materials. Additionally, the 8-edged ONMX-W is a specific wiper insert for high-quality surface finish with large cutters and high feed rate.
