Sandvik Coromant introduces CoroMill 357, a new tough multi-edge face milling cutter for roughing and cubing in steel and cast iron with high insert security. In typical applications, such as rough face milling, cubing, intermittent component figurations, components with uneven stock or forgings, welding and castings, applying CoroMill 357 achieves a high metal removal rate and superior productivity.
The CoroMill 357 multi-edge design presents a cost efficient solution because the double sided, thick pentagonal inserts housed in shim-protected tip seats provides superior production economy and reliable performance. The mill's secure, strong cutter body features an innovative insert clamping system that offers quick and easy insert indexing to save time. Large support-faces radially, axially and on the base prevent deformation and ensure consistent performance.
Suitable for ISO 50 and larger machines, CoroMill 357 takes a depth of cut up to 10mm (0.394") with a feed per tooth up to 0.7mm/z (0.0276"/z). CoroMill 357 is available in diameter sizes 100-315mm (4-10").
Distance between the bottom of the cut and the uncut surface of the workpiece, measured in a direction at right angles to the machined surface of the workpiece.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
Loosely, any milling tool. Horizontal cutters take the form of plain milling cutters, plain spiral-tooth cutters, helical cutters, side-milling cutters, staggered-tooth side-milling cutters, facemilling cutters, angular cutters, double-angle cutters, convex and concave form-milling cutters, straddle-sprocket cutters, spur-gear cutters, corner-rounding cutters and slitting saws. Vertical cutters use shank-mounted cutting tools, including endmills, T-slot cutters, Woodruff keyseat cutters and dovetail cutters; these may also be used on horizontal mills. See milling.
Typical aero-engine components that the grades can machine are gas turbine discs, casings, blisks, spools, shafts and blades. But these grades also prove to be a great choice in demanding applications such as power generation turbines and medical implants made of cobalt-chrome
SigmaNEST 24 has expanded the Task Dialog to provide greater situational awareness to the NC programmer for handling multiple projects at one time. Within the Task Window, users can create and load jobs, access workspace task reports and apply new commands to multiple tasks. Users can also monitor…
The CoroMill MR80 assortment offers cylindrical and arbor cutter bodies, with diameters from 32 to 100 mm, 3 to 12 cutting teeth and even pitch and shim protection. All cutter bodies feature internal coolant supply. The double-sided E-L50 inserts offer true and easy indexing (6 + 6), with a 3 mm…
The next-generation CoroTap 100 and CoroTap 400, with optimized performance in aluminum, can meet very strict process security demands and offer a high level of reliability and consistent tool life. The CoroTap 100 straight flute tap features refined edge rounding that helps to remove burrs and…
The Zertivo 2.0 grades enable a 30 percent increase in cutting speed recommendations for the primary ISO P and ISO M application areas, as well as secondary ISO K and ISO S materials, thanks to their optimized flute shape, which offers effective chip evacuation. The grades designed for stainless…
One of the main advantages of the new CoroMill Dura aluminum-specific end mills is their versatile performance in all different types of roughing applications, while also offering finishing capabilities,” Wikström continues. “Up to 2×D full slot, pocketing, 5–20° ramping, shoulder milling and more…
So how does Y-axis turning work? As the name implies, the new method makes use of the Y-axis, and all three axes are used simultaneously when machining. The tool rotates around its own center, the insert is placed for machining in the Y-Z plane and the milling spindle axis interpolates during…
Beyond shoulder and face milling, the end mills can also be used for pocket milling, helical interpolation, ramping and slot milling. The CoroMill 316 is part of the Sandvik Coromant Optimized Solutions offering in the company’s solid round tools range.
CoroTurn Prime B-type inserts are available for external and internal turning in a range of high-performing grades, including the new steel turning grades GC4415 and GC4425. Programming support is available in the most common CAM platforms and with CoroPlus Tool Path for PrimeTurning.
Based on a technology platform similar to the existing CoroMill® 345, this new milling concept offers a 40 percent lighter cutter body with shim protection and a high number of inserts for secure and stable machining, even in vibration-prone overhang applications. The 89.5-degree approach angle…
