World Innovation GRC giant machine for cutting rings
Company PTZ Weidner PTZ Weidner is located in the centre of the German region „Schwäbische Alb“. It is the the centre of inovazion for thin-ring cutting engineering. We offer revolutionary technologies for handling of material, cutting engineering and consecutive metal cutting operations of forged and cast rings. PTZ Weidner sets new standrads in this business segment
Company PTZ Weidner GmbH With more than 20 year experiences in engineering of cut dividing we offer a full spectrum of facilities to solving your requirements in this business: • own dividing line • as a partner in development and construction • as a partner in installation, commissioning and service • as marketing board for all related markets
Advantages of our separation process - shorter cycle times, up to 10-times faster cutting time - lower cutting width (only 3 mm) resulting in 60 % material savings - lower tool cost approx. 40 % savings - higher tool life - low cutting noise; only 70-75 db - low cutting noise; only 70-75 db - automatic work piece handling - very little creation of heat => no warp - dry material, dry chips - Safe handling of the separate rings (clamping spreader) - short chips - lower energy consumption - high parallelism 0,10 - 0,50 mm - high surface quality 1.1 – 1.6 Ra - further reduced processing times by automated material handling - unmanned work
Current technological situation for large ring cutting • cutting of big and biggest rings with existent technical equipment (grooving on VTLs) • critical process, especially in big wall thickness and heavy ring sections • economic processing only of smallest lot sizes • subesquent metal cutting operations (turning, milling, drilling1)
Work safety New Process: Current Process: Minimal risk for injury Large source für pot. injury Secure holding of ring controlled chips flow continual chips while during cutting process cutting-off short chips long chips
Our material handling solution Innovative holding solution during cutting process • universal equipment for various diameters of rings • accurate material holding during entire cutting process • simple and secure handling for finished rings • gripper can also be adapted to existing cranes and handling solutions
Our solution for your ring cutting requirements GRC giant machine for custom ring cutting • perfect cut results for � surface parallelism � surface parallelism � surface quality � very small burs • optimal cutting time • high energy and material efficiency • very economical even in low volume production
