Machine optimised hollow bar
21 December 2014
Traditionally, solid bar is the material of choice when it comes to machining components. However, when a central bore is being machined Sandvik argues that by selecting near-net-shape, machine optimised hollow bar, machine shops could significantly increase their output.

Sanmac hollow bar offers a complete selection of material choices including: 4305 UNS S30300, 304/304L UNS S30400/30403, 316/316L UNS S31600/31603, 4435 UNS S31600/31603, 2205 UNS31803/32205.
These are available in sizes ranging from: outside diameter x inside diameter combinations from: 1.22 x 0.862in, right through to 10.827 x 8.067in, and any size configuration in between, to suit customers’ production requirements. Hollow bar in non Sanmac alloys is also available on request.
