Hamar Laser Instruments is releasing its L-703S four-axis lathe andturning centrespindle alignment system. The L-703S mounts directly into spindle chucks and collets for aligning headstock spindle axes to guideways, sub-spindles and tailstocks on lathes, turning centres, and similar machines. It is also useful for guideway straightness checks during preventive maintenance and assembly, and for checking surface plates.

“The next-generation L-703 laser design features significantly higher accuracy and a few nice improvements over earlier models,” says Rod Hamar, president of Hamar Laser Instruments. “Our team’s design allowed us to reduce size, cost and complexity, increase accuracy and get rid of annoying wires by adding Bluetooth communications. With a 40% reduction in axial space over our previous L-700 model, the L-703S is much better suited to smaller lathes and turning centres. To top it all off, the price of the new system is significantly less than our older L-700 spindle kit.”

Small and lightweight, the L-703S laser is suitable for all kinds of turning applications, from small CNC turning centres and Swiss-type machines, to large-bed lathes. With a range of up to 15 m, the laser can also quickly and easily check the alignment of even very large machines.

The L-703S system features Hamar’s next-generation T-1296 five-axis wireless spindle andscan target, which can easily check all four alignment axes of a headstock spindle relative to the tailstock. The T-1296 offers a centre resolution of 0.00025 mm and angular resolution of up to 0.002 mm/m. This extremely high level of accuracy can significantly improve machine performance, reduce scrap rates and increase productivity.
