altPinpoint Laser Systems (Newburyport, MA) has developed the PLS-SAK003 spindle alignment kit for use in factories and machine shops. The laser is designed to check for parallelism, concentricity, and wear on spindles, lathes, and boring equipment, improving manufacturing efficiency by reducing downtime and reducing production costs associated with rework caused by worn spindles. The PLS-SAK003 has a round laser transmitter that fits into the spindle or chuck on the machine. A digital receiver attaches to the opposing spindle, tool holder, or tail-stock, and provides precise alignment readings through a handheld display. In four steps, the alignment accuracy offset and parallelism of the machine can be checked to better than 0.0001 in. (0.003 mm). This new alignment kit is designed for lathes and turning equipment, spindle drilling systems, and other production equipment that requires tight alignment.
