DFW Movers is not just a machinery moving company. Our Laser Precision division uses Hamar Laser Alignment Systems and Renishaw Laser Interferometers to align and calibrate machine tools. The time-consuming stair-step alignment methods of earlier years used wires, plumb bobs, straight edges, levels, box squares, knee squares, etc. Measuring each part of a machine relative to the previous part was slow and cumbersome and generally could not diagnose many machine and alignment errors. As a result, machinery was usually aligned only on initial installation. Over time, foundations crack and settle. columns lean, precision ways bend; as a result. productivity suffers, utilities increase. and rejects go way up.
Now, with just one setup, the Hamar Triple Scan Laser creates a single ultra-precise 3-D reference grid, accurate to within .001 N in 100 feet. Measuring off this laser reference grid, the Laser Precision specialists can both align and diagnose your critical machinery, restoring the productivity of your machinery lines, and saving you big money in maintenance, breakouts, and rejects.
The Hamar Laser System cut to length lines, printing presses, corrugated machinery, mills, lathes, small and large machining centers, injection mold machines, etc. The Renishaw laser is used by manufacturers in all industries, from aerospace to automotive, and all sizes. ISO 9000 requires series of quality standards that manufacturing and inspection equipment is calibrated, monitored and controlled. Laser Precision performs scheduled calibration and ballbar services so companies can meet these standards.
All motion control systems have some form of position feedback system. These, and the machines that they are fitted to, are not perfectly accurate. What is more, errors in the positioning performance of the machine will change over time as wear, damage and environmental effects take hold. Calibration using a Renishaw laser interferometer provides manufacturers with a way to achieve better accuracy and hence higher quality output from their processes.
With the addition of linear error compensation packages, the data obtained from a calibration cycle can be used to calculate compensation values, which are then automatically fed into a machine's controller. Once the compensation has been completed, a final laser check ensures that the machine's positioning accuracy has been significantly improved.
