HAMAR JsftSSS? powerful spindle }ent tool offering g accuracy and fast alignments

Lathe and Turning Center Spindle Alignment Hamar Laser’s patented, 4-axis, L-700 Spindle Alignment System is a powerful alignment tool that offers unparalleled accuracy, easy setup and significant savings in alignment maintenance time. For over 20 years, the L-700 System has been helping companies reduce tooling costs and scrap rates while increasing their productivity and profitability. It features 4-axis, live data output, so users can align lathes and turning centers quickly and accurately — up to 70% faster than with conventional methods like indicators, alignment bars or...

Reliable Alignments, Quick Results The L-700 Spindle Alignment System is a flexible, easy to use alignment tool that has become the workhorse of the industry. L-700 Laser The L-700 is a Class II solid-state diode laser with a visible beam that is user-adjustable to be concentric to the rotation axis of the spindle in which the unit is mounted. The operating range is up to 100 feet (30 m). T-261A 4-Axis Spindle Target The T-261A 4-Axis Spindle Target has the most angular sensitivity of any Hamar Laser target. It reads both center and angle (pitch and yaw) simultaneously, allowing a...

One of the most important calibration factors for lathes and turning-type machines is the alignment of spindle axis of rotation (AOR) to the tailstock bedways or the saddle bedways. The other critical calibration factor is the alignment of the spindle’s AOR to the tailstock, sub-spindle, turret or tool holder. Conventional methods are cumbersome, time consuming and practically useless on large lathes. The L-700 vastly simplifies the task by inserting the laser right into the spindle chuck and then using the T-261 4-Axis Target mounted in the tailstock, the laser is aligned to the spindle’s...

Other Applications Transfer-Line Spindle Alignment One of the biggest problems with transfer lines is broken taps, drills and reams which can stop production. A big factor causing broken tools is poor angular alignment, especially for taps. When a tap tries to enter a hole and the angular alignment is poor, it results in premature tool wear and breakage. The critical alignment of a transfer line machine is the axis of rotation of the spindle to the master part or pallet. A 1/2” stud on the L-700 Laser is inserted into the spindle chuck and the laser beam is aligned to the axis of rotation...
