Contact Details
Sandvik Coromant's exchangeable-head (EH) system includes a wide assortment of solid carbide heads, indexable milling cutters, boring heads, integrated machine adaptors and different shanks.
The exchangeable head coupling is based on a self-centering screw thread for secure mounting and maximum strength and security. The coupling has a physical stop which makes it easy to feel when the head is correctly tightened and helps to not overstress the clamping. The conical portion is shaped to provide best run-out. Pre-loaded taper and flange contacts provide an optimized modular connection with extreme rigidity and strength.
These new extensions meet the requirements for long reac in large machining centres in the diameter range of 0.394" to 1.26 inch (10 to 32mm) for milling and 0.039" to 1.42 inch (1 to 36mm) for boring.
Related Glossary Terms
- boring
boring
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.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- milling
milling
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.
