Hamar Laser’s L-742 being used to align a Wenzel RS-series CMM
Borbolla Metrology has been using Hamar Laser’s L-742 Ultra-Precision Dual Scan Laser to align Coordinate-Measuring Machines (CMMs) and other machines for many years. The L-742’s 2 automatically sweeping, perpendicular laser planes has performed very well in the field. The laser is highly accurate and easy to use and lets us perform machine alignments more quickly. The L-742 sets up easily and gives us alignment data extremely fast and in real time. We do not see these qualities in other alignment tools.
Our company is a distributor of measurement equipment, specializing in dimensional metrology, and sells and services CMMs. We started in 1996 in order to offer these services with a high degree of professionalism and customer service. We have worked with Hamar Laser from the beginning because they share our commitment to delivering superior service. The company is always very responsive to our needs and is extremely quick to resolve any issues.
CMMs measure objects’ geometry by sensing discrete points on their surface with probes. We recently used Hamar Laser’s L-742 to align a Wenzel RS-1618. The RS-series are horizontal arm CMMs used for measurement of vehicle components, assemblies and other large parts. We use the L-742 system to level and make the table flat when the table is cast iron, and to rough-square the machine mechanically. Because it is so easy to set up and gives us data so quickly, the L-742 saves us a lot of time when setting up or servicing CMMs. The L-742 saved us four hours, for example, when we aligned the RS-1618.
Hamar Laser has been a trusted supplier for us for more than 25 years. Our customers and machine manufacturers, such as Wenzel, really like Hamar Laser’s technology. We think anyone that needs highly accurate and very easy-to-use alignment systems, and who wants very responsive customer service, should consider working with Hamar Laser.
I want to give you some feedback on our first alignment with our new Hamar system [L-743 Ultra-Precision Triple Scan laser]. We used it to install and align a new bridge mill. It worked better than we expected and was so much easier than the levels [and granite squares] we’ve been using in the past. We leveled and squared the bridge mill with the L-743 in 1.5 days instead of the 4-5 days it would have taken using our old equipment! Based on this time savings, we think we will get a payback in 9-12 months!
I’m currently a site manager who has been working at hydroelectric facilities in the U.S. Our team uses Hamar Laser Instruments’ L-740 Ultra-Precision Leveling Laser for checking level and flatness on large components, including rotors, stators, imbeds and turbine components such as head covers and facing plates. We also use it for in-situ machining, and checking our “as found” flatness measurements. Based on about 15 years’ experience with it, I can tell you that the L-740 is the best tool out there for leveling applications like these.
We use a variety of measuring tools at our facility, but your L-740 is my guys’ “go-to” favorite for these applications. Compared to our optics kits, the L-740 is much faster and easier to use, and more importantly for me, easy to teach. I have much more confidence that I can send out a tech with the L-740 and know the job will get done fast and done right. Unless a technician is really experienced at optics, it can take a lot more time for him to set it up and finish the job. I also really like the L-740’s built-in, easy-to-read, high-accuracy level vials that make it simple for less-well-trained guys to use without a lot of trial and error.
Then there’s the accuracy. We work with a lot of large surfaces (30+ feet), so having that added accuracy makes the measurement more repeatable and our confidence in the numbers higher. [Ed. Note: Accuracy is .00003 in/ft.] We’ve been very happy with Hamar Laser and your L-740 leveling laser is an especially important weapon in our arsenal. It’s been a great investment and I’m sure that we’ll be using it for at least another 15+ years!
L-743 Leveling Sawmills Log Rollers
Our new L-733 Precision Triple Scan® Laser has been working great in the saw mill where I work. So far we have used it to fix a couple of issues that have plagued our machine for years. I love it!
Our main application is to align machine centers. We have two Chip-n-Saw lines, one large and one small. We also have two edgers. Our alignment consists of making sure our machine line is level, straight (in-line) and square to itself within .005”.
On our small Chip-n-Saw line we had an issue that we thought was due to the outfeed line bar being installed at too high of an elevation compared to the infeed line bar and profile rolls. With the laser we found the infeed line and profile rolls were dropping in elevation, so by the time we reached the outfeed line bar we were running into it. We also found our profile roll box was out of square, which made it impossible to set both rolls square to our feed.
I like that the L-733 lets us shoot straight, elevation and square measurements in just one or two steps, and that it gives us real-time numbers. This is extremely helpful when having to move something back in line. I also like your R-1308 plug-in digital readout that attaches to the target for taking measurements, especially when we are moving something, because there is no delay. I can see the data right away.
I had a couple of questions with the PDA, but your customer support team got me lined out on how to work it. There is a bit of a learning curve for some of our millwrights but the laser is easy to use and they are coming around fast. Overall the laser is a really great tool. If I have any issues, I will contact you and your team. Thank you!
The payback is pretty high using laser alignment techniques. Based on my customers’ results, they see that better recovery and other benefits can make precision alignment pay for itself very quickly. Most sawmills have accepted lasers. Laser alignment works so well, we don’t have to convince anyone anymore. The sawmills just call us up now, and we have been very busy!
I am very impressed with the overall fit and finish of everything. The Kaisen foam is well designed and every component has a well thought out home. The position and orientation of each component was done in such a way to provide maximum protection of the important pieces. The canvas bags that the stand accessories come in are a very nice touch. The stand components and the methods used for assembly are very high quality. Quality you can feel and see. The tablet preloaded with the training videos which are organized into logical albums will also be extremely handy in the field. The selection of the tablet model and the supplied case are a very attractive pairing. The case is one of the best quality industrial units I have felt. The neck strap is also super handy for the intended use. Finally, the training session was also a very positive experience. Spending time with Darel was not only valuable for the equipment use training but also for his wealth of knowledge and years of experience in the alignment field. We are confident that we teamed with the right group and are very excited to start “Aligning with the best!”
We’ve been using a Hamar Laser alignment system for 15 years. When anybody sees it in action, they see how accurate it is, how it shows alignment data in real time and how easily the results can be repeated. After that, well, the skeptics become believers.
Pipe probe uses L-706 Laser as reference
In late 2010 our company received an order to develop a system that would make precise measurements of inner diameter and non-linearity of refurbished oil rig pipes. The idea was to combine several measuring sensors (diameter, non-linearity, inclinometer, rangefinder) in one autonomous wireless probe. The first challenge was to find manufacturers who were willing to work with OEMs. The second challenge was to find an alignment system. Thus there are many different systems on the market. We could only find one that claimed to have suitable accuracy with proper sensor size and that was the L-706 system from Hamar Laser. Mr. Rod Hamar gladly agreed to customize system circuitry to fit in our probe. While working on the project we faced several programming problems. Those were solved fast by Hamar Laser support, and several microprogram changes were made to match our protocols. The system proved to be reliable, robust and even more accurate then we needed. “Proudly made in the USA” exactly describes Hamar Laser.
The ROI on our Hamar Laser L-742 [Roll Alignment System] alignment system was only 3 months! Thanks for a top-shelf “rubber meets the road” solution!
Just a note to let you know, we completed alignment of the Mazak Slant bed lathe shortly after you and Guy finished your visit with us. We found the head was out of parallel with the bed along with level and twist in the bed. Using your system we were able to re-level and adjust the machine to accuracies within tenths regardless of position through the length of travel. This is the beginning I was sure we could get to and I appreciate your help in getting there. Now I have to drive this program to a consistent level. This helps greatly. Thanks again!
We adopted the use of the Hamar Laser alignment system in 2005 and have not looked back since. With its high accuracy and easy-to-use design, our machines’ performance has improved tremendously. Your alignment system allowed our machines to run much faster than their design speeds and to produce finer copper foil more reliably. With this experience, we have started to equip our other sister plants around the world.
L-706 Steam Turbine Laser
We have been using Hamar laser equipment for about 14 years and have had nothing but great support from your staff all around, from your receptionist to those doing sales and service. Last year, Craig in your service department worked closely with us to adapt a 1308 readout to use a heavier duty plug vs the smaller standard plug used to connect with one of the A1519 sensors. Your ability to work with us to customize our equipment was much appreciated, and a testament to your willingness to listen to the needs of your end user. Our turbine alignment business depends on our gear being both accurate and dependable, and Hamar Laser delivers on both fronts. Without the equipment you manufacture and your customer support, it would be much harder for me to run my business. Thanks for your continued support.
We have used the system now, and it really is good. We used it on an old (circa 1950) crusher motor (200 hp 550 RPM) with a horrible motor base. It helped us get through the massive soft foot issues reasonably quickly, and the alignment was a breeze once we were done with that. The controls were simple and intuitive, and the touch screen made data entry very quick. The constant updates while we moved the motor made the adjustments very easy. The Bluetooth was also very convenient. It was something we initially thought wasn’t necessary, but with large motors it was very nice to be able to walk around with the PDA. It had very good range too. We finished with the motor aligned within very tight tolerances. Overall, I am very happy with the system. I was able to pick it up, and align a motor accurately the first time, with very little training and no previous alignment experience. Thank you for making such an easy to use and accurate system.
The machine move stage is the most critical step in any alignment. Behind its great graphics, this is where we have seen the very high resolution and accuracy of the system pay real dividends, because the live move data on a Stealth system has proven to be dependable and accurate like never before. I have been very impressed to be able to align a new motor to close tolerances on several occasions with only one alignment measurement, one combined vertical and horizontal live-move correction and a confirmation retest – job done!
