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

• f 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
• perations (turning, milling,

drilling1)

Work safety

New Process: Minimal risk for injury Current Process: Large source für pot. injury

Secure holding of ring during cutting process

controlled chips flow short chips continual chips while cutting-off long chips

Our material handling solution

• universal equipment for various

diameters of rings

Innovative holding solution during cutting process

• 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

• perfect cut results for

surface parallelism

Cutting example: Inconel 718

• utside ring Ø 712 mm inside Ø 608 mm

forging cut size 3 mm

Cuttding example: ball-bearing steel 100Cr6

• utside ring Ø 955 mm inside Ø 785 mm

forging cut size 3 mm

Front surfaces machining

Cutting does not require additonal surface treatment

Very low cutting temperature

The low heating of the tool increases tool life, less tool changes and no cooling fluid required

Examples of divided rings

Innovative machine operation

• perating is characterized by simple

machine control and operator interface

Integrated solution: Cutting and material handling

• Use of existing equipment possible;

Integrated solution: Cutting and material handling

• Use of existing equipment possible;

adaptation of dividing and handling unit in existing machines possible

• combination of cutting and other processes in one set-up
• increase in economy and flexibility
