Let’s say you want to machine your initials on your favorite Hummel figurine or cut the likeness of the school mascot on your daughter’s Little League helmet. How are you going to grip them? A conventional way to grip fragile, difficult-to-hold workpieces is to encapsulate them in some sort of potting compound, a time-consuming and wasteful process.

Urschel Laboratories Inc. manufactures industrial equipment to slice, dice, shred and mill virtually any food product.
According to Bill Monroe, senior manufacturing engineer for Urschel, the company machines parts for the food processors at its only manufacturing facility, located in Urschel’s 350,000-sq.-ft. headquarters. Urschel produces many of these workpieces in its two foundries. “We have a no-bake foundry and an investment foundry,” Monroe said.
As part of a major new project that Urschel, Chesterton, Ind., started late last year, Monroe needed to hold a 300-series stainless steel billet that was convex on one side and then access five sides when machining it on a 5-axis machine. Read the rest of this entry »
Adhesive Workholding Allows Turbine Blades To Be Ground In One Hit
Technique offers the possibility of automated production
A new method for securing a turbine blade prior to machining by gluing one side of its aerofoil to a fixture, rather than using mechanical clamping, allows the root and tip to be ground in one operation. Traditionally, due to clamp interference, at least two operations are required on conventional CNC grinders to machine the fir-tree and wedge face on the root as well as the shroud end features at the tip.
The one-hit manufacturing process is not only faster, but also eliminates work-in-progress and the risk of introducing inaccuracy due to repeated refixturing. The technique is being developed in the UK by NCMT, which sells Makino’s VIPER grinding platforms across Europe. Since May 2015, the company has also been European agent for the patented Blue Photon photo-activated adhesive workholding system from the USA. Read the rest of this entry »
The 82400 Spindle Mounted Gripper Cleaning tool mounts in any 3/4 diameter collet or end mill holder. The assembly comes with the tool, a spring-loaded, replaceable head and the HAAS program.
After removing the part from the grippers, you can insert the fixture back into the machine, insert the Spindle Mounter Gripper Cleaning Tool, and run the program. The head grinds residual, cured adhesive off of grippers in seconds. You are ready to load a new part without resetting the grippers in the fixture. The replaceable head is good for 1000 to 1250 cleaning cycles when using the Blue Photon cleaning cycle parameters and a coolant.
The Problem: The brittle nature of ceramic was easily damaged when traditional workholding methods were being used.
The Solution: Blue Photon’s photo-activated workholding system was designed to eliminate scrap from fixture induced damage and part movement during processing.
Additional Benefits: By implementing the Blue Photon workholding system the manufacturer was able to eliminate clamping induced scrap, part movement during machining and increased output feed rates. Overall, the manufacturer saw quality improvements. The new workholding system allows for easy automation of this highly valued part.
We are proud to announce that we have established a strong network of well-trained manufacturers’ representative agencies to cover sales and support throughout the U.S. Individual sales representatives from the following agencies will take the lead introducing Blue Photon grip technology, and supporting end users with training and applications.
For additional representative information, visit our website at BluePhotonGrip.com/contact/find-a-rep or contact us to schedule a hands on demo of Blue Photon’s patented workholding system.
Introduction of the sales network coincides with the release of our updated website. The new site features in-depth technical product information, instructional videos, and full descriptions of system components and how they work.
Blue Photon is a photo-activated, adhesive workholding solution that first hit the market in the aerospace industry. Complex-shaped, hard-to-hold parts, and delicate materials like ceramic and laminated composites are keenly suited to the technology which supplies up to 605 lbs of tensile holding power. However, it soon became apparent that the technology was well suited to every industry from automotive to medical. Any part that is at risk for distortion from traditional clamping, or that poses complications in fixture design is easily and simply held with Blue Photon’s patented grippers and BlueGrip™ workholding adhesive.
We look forward to hearing how Blue Photon can help you!
