Current ProcessZirconium tubes are cut one at a time using carbide tools on a lathe. A lathe cutoff leaves burrs requiring deburring to achieve a smooth surface finish. Carbide tooling wears quickly when cutting zirconium and is expensive. ChallengesDeliver a cost-effective process to cut zirconium tubes which reduces the numb...

Challenge: The customer was outsourcing grinding of components and came to Glebar looking for a way to reduce lead times on parts, reduce costs, and bring grinding capability in-house. Original challenge was to thrufeed 1-½” diameter, 15’ aluminum tubes removing 0.003”-0.006” per pass. The second requirement was for the machine to be ...

Challenge: To accurately grind alumina spacers used in nuclear power plant control rods. The length of the components are extremely critical to the efficiency of the fuel rod. The components need to be processed at a high rate and length verified for all parts. Solution A DD-7 double disc grinder was configured with 0.1 micron closed loo...

Current ProcessA high-powered laser beam cuts the tubing by melting it leaving a rough edge and slag. Tubes and other parts are typically cut one at a time limiting production rates.ChallengesHeat sensitive applications may limit the use of the laser for cutting. Laser cutting leaves recast and heat-affected zones, affecting the tube’s quality an...
