Magnetic Chucks Hold Extremely Large Workpieces, Prevent Tool Damage, and Improve Surface Quality

For exact machining of thin-walled rings on rotary tables, cylindrical grinding machines, and lathes, SCHUNK now offers a vast program of standardized magnetic chucks with radial pole pitch. MAGNOS radial pole plates work with electrically activated permanent magnets and are proven for hard and finish turning, as well as grinding and rough machining.

The workpiece can be machined from three sides without a changeover and since the magnetic field is active up to the outer fringe areas, extremely large workpieces can now be clamped securely and deformation-free. Due to the two-dimensional acting holding force, vibrations are greatly reduced during machining. This prevents the cutting edges of the tools from damage and improves the surface quality of the workpiece.

Depending on the individual application, three different sizes of standardized radial pole plates are offered. For grinding operations, an AlNiCo single magnet system with automatic demagnetization, for turning operations, an AlNiCo double magnet system with high holding forces. The third one is for demanding volume machining during rough turning, an extra strong AlNiCo neodymium magnet system.

New End Mills Designed for Roughing and Finishing with Increased Feed Rates, Reduced Chatter

Helical Solutions’ new HEVR-5 and HEVR-RN-5 five-flute, variable-pitch end mills are designed for roughing and finishing of steel and exotic materials with increased feed rates and reduced chatter.

HEVR-5 and the longer-reach, reduced-neck HEVR-RN-5 tools are crafted of certified premium sub-micron grain carbide and feature geometries specifically engineered to cut ferrous material. The tools are available with an AlTiN (titanium aluminum nitride) coating for oxidation resistance and extreme hardness for slotting, peripheral milling, ramping and helical interpolation of Stainless and other steels, cast irons, titanium alloys as well as cobalt- nickel- and iron-based high-temperature alloys.

The HEVR-5 tool series features corner radii for added strength and has a variable-pitch design for increased depth of cut, up to 1 times the diameter of the tool resulting in an increased metal removal rate along with minimizing any possibility of chatter. Additionally, and due to its unique design features, it is not uncommon for customers to utilize the HEVR-5 for both roughing and finishing, reducing the number of tools and setups.

The HEVR-RN-5 series is designed for applications requiring extended reach into pockets or machining around obstructions. The stub flute length and a reduced neck contribute to excellent tool rigidity even considering the greater tool length.

Speeds and feeds for the tools range from 80 to 250 sfm and 9 to 27 ipm for Stainless, 60 to 125 sfm and 2 to 10 ipm for high-temperature alloys, 500 to 600 sfm and 23 to 76 ipm for steels, 400 to 600 sfm and 24 to 73 ipm for cast irons, and 160 to 190 sfm and 7 to 15 ipm for titanium.

“Although these tools can be used for roughing applications, they are ideal for finishing the hardest and most-difficult-to-machine materials,” says Helical Solutions National Sales Manager Scott Tiehen. “And with the higher speeds and feeds, and increased tool life they provide, they offer significant benefits in efficiency and cost.”

Helical recommends using high-pressure coolant, flood, mist or dry milling with air blast when machining with these tools, which are available in 1/4-inch, 5/16-inch, 3/8-inch, 1/2-inch, 5/8-inch, 3/4-inch, 1-inch and 1 1/4-inch diameters.

Groove in Boring Insert Always Produces a Perfect "Chip Off the Old Block"

Walter believes there is room for even more improvement in the boring process. This is why the US tool manufacturer has expanded its range with a new indexable insert with E47 boring geometry for the Walter Valenite Boring Medium and Walter Valenite Boring Maxi tooling systems.

One prominent feature in particular is responsible for such improvement in quality and performance: behind the cutting edge is a variable chip breaker groove that produces perfect chip formation even when relatively deep cuts are required. This proves most beneficial with variable depths of cut, such as those often involved in the machining of cored holes. No matter how far the cutting edge penetrates, it always produces a perfect chip.

The new insert is circumference-sintered and conforms to basic shape CC. The E47 universal boring geometry has a 15-degree rake angle, moderately rounded cutting edge radius and a 7-degree clearance angle. The straight cutting edge makes it possible to machine dimensionally precise shoulders, typically of 90 or 75 degrees, without profile distortions.

The E47 insert is available in three cutting materials. The CVD-Tiger•tec® WPP20 grade is the first choice for cast iron and steel. The PVD-Tiger•tec® WSM20 and WSM30 grades are available for more difficult machining conditions. These cutting tool materials are extremely tough, making them suitable for steel, stainless steel and other materials with difficult cutting properties. Interrupted cuts, which are common to the boring process, are no problem for these grades.

The new insert was developed for the Walter Valenite Boring Medium and Walter Valenite Boring Maxi tooling systems, both of which support the entire boring geometry range from 0.787” to 25.20” (20 mm to 640 mm). The combination of tool, Tiger•tec® cutting tool material and E47 geometry ensures maximum process reliability for the shortest machining time.
