Seco continues to evolve and develop tooling solutions for the metalcutting industry. Two of the company’s latest examples of that are its EPB 5831 slim hydraulic chucks (pictured) and ER-to-Combimaster holders.
The new EPB 5831 chucks expand Seco’s line of hydraulic chucks. Featuring slender profiles, the chucks allow shops to easily perform semifinishing and finishing operations in confined spaces such as deep, narrow mold cavities. In addition to their slim designs, the chucks are available in long projection lengths of 150 mm and 200 mm.
With the turn of one pressurized screw, the high-pressure hydraulic chucks uniformly grip small-diameter cutting tools. Such secure clamping ensures extreme precision and high repeatability along with runout of less than 5 µm at 3xD for fine surface finishes.
The EPB 5831 accommodates 6-mm, 8-mm, 10-mm and 12-mm tool diameters, and with the use of reduction sleeves, the chuck holds various shank types and diameters. With a reduction sleeve for instance, the 12-mm hydraulic chuck can hold 3-mm, 4-mm, 5-mm, 6-mm, 8-mm and 10-mm tools. The chucks are available in HSK-A63, HSK-A100, BT 40 and Seco-Capto C5 machine side connections.
Seco’s new ER-to-Combimaster holders bring ease of use, stability and unlimited possibilities to multitask machines, according to the company. This system combines ER taper, ER clamping nuts and a ball bearing interface, all of which provides unmatched tool positioning and secure tightening during setup.
Highly adaptable, the ER-to-Combimaster tooling system performs face, side and disc milling operations via insert-based milling cutters, as opposed to solid endmills. This allows for higher material-removal rates due to larger cutting diameter capacities. Plus, the system’s compact design with short overhangs saves space in the machining area for improved safety and reliability.
Combimaster is available in three ER sizes – 25, 32 and 40 – and five different Combimaster thread-size connections ranging from M8 to M20. The system supports a range of interchangeable milling cutter heads, especially those in Seco’s Turbo line.
Related Glossary Terms
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- metalcutting ( material cutting)
metalcutting ( material cutting)
Any machining process used to part metal or other material or give a workpiece a new configuration. Conventionally applies to machining operations in which a cutting tool mechanically removes material in the form of chips; applies to any process in which metal or material is removed to create new shapes. See metalforming.
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.
- milling cutter
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.
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
