Motch Corporation, Cleveland, Ohio

Inspection of 2 large machine slides approximately 2′ X 5′ X 8′, weight 10,000 lbs.
The customer Motch Corporation had an outside vendor machine two large cross-slides for a large precision grinder.
The problem was that Motch wanted the cross-slides inspected at the vendor’s plant before shipment. The slides were checked for thickness, width and length with conventional measuring tools, but Motch also wanted to verify flatness, squareness and parallelism of the slides. Typically, this type of a check would be performed on a computerized measuring machine, but the size and the location of the parts prevented this.
Motch called Hamar Laser to come to the vendor’s plant to check the geometry of the slides.
I came to the vendor’s plant with a L-723 Ultra-Precision Triple Scan® Laser Alignment System. I found minimum errors on all checks. I recorded all data on paper, then entered the data [220 points] into Hamar Laser’s software program for the L-723. After entering the data and printing out the graphs, I gave the information to the engineer in charge and he reviewed the data and graphs. After the review he gave the plant manager permission to ship the parts.
Time: 5 hours for both parts, including setup, data entry and report generation.
This demonstrates that large parts and machines can be inspected with a laser where other means are not possible.
* The L-723 Triple Scan® Laser Alignment System that was the subject of this case study has been superseded by the L-743 Ultra-Precision Triple Scan® Laser Alignment System.
