Walter has broadened its line of boring tools with the introduction of the B3220 boring cartridge for axial-radial offset roughing (ARS), expanding on previous methods that were either symmetrical or asymmetrical. This versatile new tool, designed for use with the Walter B3220 but which can be used with the Walter B3221 and B3224 boring tools as well, brings the capabilities of axial-radial offset roughing (ARS) to an array of new applications.
By doubling the tool’s cutting widths, the new cartridge increases metal-removal rates, saving time and, thus, money. Costs are further decreased since the B3220 boring cartridge saves users the need for additional processing steps and tools. In addition, the tool provides good chip control, stable machining conditions and heightened process reliability.
All common ISO materials can be machined with the B3220 boring cartridge, which can accept an extensive range of indexable inserts. It excels at thru hole, line hole, and step cuts and is ideally suited for chassis, large engine and gearbox roughing in the automotive industry. In general engineering it finds application in the roughing of bearing holes, machine housings and compressor housings. In the railway industry it brings new efficiencies to chassis roughing.
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
The drills are coolant-through, straight flute (G-drills), with emulsion or oil and coolant pressure of 145-580 PSI (10-40 bar). They are offered in cylindrical shank configuration and have a 120° point angle with tolerance of m7. They are also offered in L/D ratio of 5 x Dc as standard, with…
The MD173 Supreme is a roughing cutter designed specifically for dynamic milling and for reducing machining time. Its cutting edges equipped with chip breakers enable excellent chip breaking, permitting superior process reliability with high metal removal rates, a plus for users with automated…
A patent-pending, highly textured, multi-layered MT-TiCN layer increases toughness and reduces flank face wear, resulting in lower cost per cutting edge. The inserts’ highly textured Al2O3 layer also minimizes crater wear, and the gold-colored top layer improves wear detection. The gradient carbide…
This grade is now capable of longer tool life, greater reliability, and approximately 30 percent greater performance in stainless steels (ISO M) and heat-resistant super alloys (ISO S), and up to 75 percent greater performance in steels (ISO P) than comparable grades. With the launch phase now…
These new vibration-free tools provide finish machining of precise bores (IT6–IT8) up to 6 × D, with high surface quality and are up to three times more reliable and flexible than comparable models. Their flexibility is boosted by the fact that the new Walter boring tools employ modular components…
With the TC630 Supreme, users can benefit from a range of advantages. A high level of process reliability for unstable machining operations, for example on lathes with driven tools or for long overhangs. Areas of application include medical engineering, precision engineering, the aerospace sector…
Walter has introduced the Xtra·tec® XT M5460, a new profile milling cutter that delivers maximum precision, tool life, and surface quality in precise machining of freeform surfaces and deep cavities.
These indexable turning inserts are designed for applications where a soft cut and high precision is required. Long tool life is achieved through the WEP10C coated cermet grade with multilayer PVD TiCN TiAlN coating and extra fine cermet substrate grain. Walter's combination of edge…
The WNN15 grade delivers outstanding process reliability and long tool life, even at extremely high cutting speeds. This means that it makes indexable insert drilling more cost-effective than comparable PCD tools with immediate effect. The indexable insert drills offer the advantage of multiple…
