The AX024 Silk Clamshell is a larger version of the AXL012 and has a maximum clamping capacity of 584mm (23”).

It has an eight independent jaw clamping arrangement, and is driven by two 1.7kW (2.3hp) high torque pneumatic motors.

The two continuous, automatic feeds offer a fine and a coarse surface finish.

Like its smaller brothers, these precision tools have a host of interchangeable “Bolt-On” extras covering almost any machining operation offered in a conventional machine shop. This flexibility provides a highly cost effective solution to field machining applications, saving both time and money.

Eight separate adjustable clamp blocks are provided.

These can be positioned on the base ring to suit the size of flange being machined.

The arrangement enables the machine to be locked in position and centred relative to the flange using adjustable screws on the clamp blocks.

The drive ring module, incorporating the bearing assembly, provides the drive for the saddle via a worm, worm wheel and internal gear arrangement.

Power driving the machine is provided by two 1.55 hp pneumatic power units mounted on the drive ring.

The saddle is mounted on the drive ring and bearing assembly and provides a rigid structure to which the toolpost is fixed.

With drive provided through the drive ring internal gear arrangement and saddle pick-up gear, the saddle and support bearings rotate around the internal gear in a planetary motion.

Toolpost traverse in and out is provided by a lead screw driven by the saddle gear train. Traverse is selected by a traverse selector.

The machine can achieve cuts to a maximum of 0.39″ (1mm) without flanged holes and 0.020″ (0.5mm) with flanged holes.

Alternative tool posts can be fitted to the saddle depending on the machine application.
