Hamar Laser Introduces L-703 Bore & Spindle Alignment Laser

Compact & versatile new design excels at hard-to-align twin-barrel extruders

Hamar Laser is pleased to introduce its L-703 Bore & Spindle Alignment Laser, a compact and versatile laser with many applications, including bore alignment, barrel and cylinder straightness, spindle alignments and hard-to-align twin-barrel extruders.

“One of our overall design goals is to make our lasers smaller, more versatile and at a lower price whenever possible,” said Rod Hamar, President of Hamar Laser Instruments. “So, when we designed our L-703 to replace our L-706 Bore laser a nice ‘problem’ happened: we found out it quite nicely solved a long-standing application request we’ve had for twin-barrel extruders. Lo and behold, we sold several units before we had finished the design and now have yet another application for this multi-purpose laser!”

Hamar Laser’s new L-703 is combined with the company’s patented self-centering bore-measuring targets for extruders in the L-703 Twin-Barrel Extruder Alignment System kit, which also includes Hamar Laser’s new A-703T Spline-Shaft Adapter, A-510 2-Axis Target, bore adapters, readout and accessories. Additional L-703 Laser kits for other applications, including bore and spindle alignment and surface plate calibration, will roll out later this year.

Customers who already have the L-705 Extruder Borescope Laser for single-barrel extruders can now align twin-barrel extruders by purchasing just the L-703 Laser and A-703T Adapter and use the rest of the L-705 system components. Designed specifically for the L-703 Laser, the A-703T Adapter positions the laser on the end of the spline shafts on twins for alignments in tight spaces and features an adjustable centering plate to accurately indicate-in the center mounting hole to the rotation axis.

“The small L-703 Laser solves the space-limitation problem that makes aligning twins difficult,” said Hamar. “The laser is short, so it’s easy to use with the typical limited space off the end of the gearbox shaft. This allows the laser to be aligned to the shaft rotation axis so each barrel section can be aligned to a common reference, resulting in much better alignment. This eliminates errors that come from trying to use the outside of barrel sections to check the alignment, since these may not be parallel to the inside.”

“Extruder misalignment causes barrels and screws to wear out quickly and leads to expensive repairs, not to mention causing heavier electrical consumption” continued Hamar. “Our L-703 makes aligning twins much easier and faster so we’re excited about getting this news out to our customers and prospects.”

Testimonials…

" I’m a field vibration analyst with CMS, a company that provides full-service PM support. The [X-990] is the best shaft alignment system I’ve ever used, and I’ve used it to align everything from extremely small pumps to large pumps for power plants. There’s a lot I like about Hamar’s [X-990]: You can leave the heads in one position and make the vertical and horizontal moves, a big time-saving feature. It’s extremely accurate, transmits alignment data wirelessly using Bluetooth and has a very intuitive, easy-to-use software package [Couple6]. It incorporates ambient lighting correction and has a sun filter for outdoor jobs, and it uses a PC tablet instead of a dedicated display. This tool makes us really shine as reliability pros. We’ve been very happy with Hamar Laser and the [X-990]!"
