1.0 Technical Information
The XL-CSLM is specifically designed for machining various horizontal, circular surfaces from 6 to 50 meters (20 to150ft).

The XL-CSLM utilises a rotating (or scanning) laser source beam light as a reference. The laser can be set up horizontal or tilted to a desired place. A precision target detects the beam and the reading is displayed on a digital readout. Engineering lasers are accurate to within 0.05mm (0.002”) over a distance of 15m with a resolution of 0.01mm.

The XL-CSLM consists of a structural box supporting a milling cutter between wheels travelling upon the surface to be machined. The structural box is extended to the centre with structural beams connected to a central pivoting system (CPS). The milling machine assembly rotates around the circumference from the central pivot.

A rotating laser source, mounted above/on the CPS, is used as the independent reference. The reference is adjusted parallel to the desired plane to be machined. Laser sensing targets attached to the travelling wheel frame sense the position of the frame height relative to the laser beam. The electronic-hydraulic interface system then automatically and continuously adjusts the travel wheel position on the surface. The wheel position maintains the frame position relative to the plane of the laser beam as the wheels travel through peaks and valleys upon the surface.

The milling box frame can accommodate two 400mm (16”) milling cutters simultaneously, depending upon actual application.

The interface/control system has the ability to control the machine to within 0.02mm relative to the laser plane. The final flatness envelope, depending upon thermal distortion, is typically 0.2mm (0.008”).

2.0 Advantages
The XL-CSLM uses a precision scanning laser to reference through interfacing and will machine to the laser plane.

The laser interface controls the milling head position.

The laser is used to adjust the milling cutter to ensure machining results are parallel to the laser plane, continuously monitor the flatness as the job progresses, and performs surveys.

The laser plane can be adjusted quickly without mechanically adjusting the machine. The laser plane can be continuously adjusted to specific datum points during the application.

The initial installation time of the XL-CSLM is approximately 12 hours.

Maintaining accuracy is superior to placing and continually adjusting conventional machine rails in radial and circumferential directions.

Once a circular face has been machined to tolerance, the mill box can roll around this face and machine other concentric areas including vertical, horizontal and overhead faces exactly parallel or perpendicular to the original face.

Digital readout from the laser plane allows the client to witness the survey results.
