The Silk AXL012 is a lightweight, robust, precision machining platform.

The solid circular drive ring utilizes an independently adjustable four jaw clamping arrangement for mounting the machine externally, on regular and irregular surfaces up to 305mm (12”) wide.

It is powered by one 0.8kW (1.1hp) high torque pneumatic motor and rotates on a high precision bearing giving excellent rigidity.

The machining centre also features continuous automatic feeds enabling the production of industry standard surface finishes.

The Silk AXL012 offers versatile repair capabilities to a wide range of plant and equipment. Typical applications include the re-facing of pipeline flanges and connectors ranging from gramophone finished raised faces to precision O-ring grooves. With the addition of easy to install, bolt-on “kits” the machining centres may be adapted to repair RTJ grooves, to machine valve seats and to produce bores.

Four 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 a 1.55 hp pneumatic power unit 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.
