Tangential rolling system TSW24

Data sheet

For maximum precision in the machining of sensitive sealing surfaces, we offer you an efficient and reliable alternative to time-consuming grinding. When smoothing the sealing contour Ø 18.0 mm to a width of 38.5 mm, we achieve a surface quality that far exceeds the requirements – even with demanding materials such as 1.0501 (C35).

Task

Application:

  • Smoothing a sealing surface: Ø 18.0 mm/38.5 mm width
  • A surface quality of max. Rz 2.5 µm is to be achieved


Material:

  • 1.0501 (C35)
  • (tensile strength 550 N/mm2)


Current proces / customer request:

  • The workpiece is pre-machined and then the sealing area on the workpiece is ground
  • The grinding time is approx. 15 seconds
  • The external grinding process is to be omitted at the customer's request

Solution

  • Process changeover to TSW24 tangential rolling system with rolls specially designed for the application

Customer Benefit

Process:

  • Downstream grinding process is no longer necessary. (No further handling, transport or waiting time necessary)

Quality:

  • The requirement of max. Rz 2.5 µm was exceeded. After machining with TSW24, the sealing surface has a surface finish of Rz 0.7-1.6 µm. (depending on the allowance of the turning process)

Time saving:

  • The machining time is reduced from 15 seconds to 8 seconds

Thread cutting system Z64

Data sheet

Precise thread machining without distortion – even with thin-walled tubes

Our customer faced a particular challenge when it came to tube machining: after thread production, the workpiece was not allowed to show any out-of-roundness. Until now, a special machine was used – which involved high costs and limited flexibility. The solution: the use of our Z64-2 thread cutting system in combination with specifically matched Strehler holders for the respective threads.

Task

Application:

  • Pipe machining with M16 thread


Material:

  • S235 (tensile strength 350–500 N/mm2)


Lot size:

  • 250,000 pieces


Current process / customer request:

  • Special machine
  • After threading, the workpiece must not be out-of-round

Solution

  • Use of a thread cutting system Z64-2
  • Different chaser holders for the individual threads
  • VC = 15m/min

Customer Benefit

Top Ergebnis:

  • Großer Arbeitsbereich von M16–M63×1,5
  • Durch die spanabhebende Gewindefertigung, können dünnwandige Rohre bearbeitet werden.
  • Strehler können nachgeschliffen werden

Thread cutting system ZA16

Data sheet

The process for manufacturing a special screw with an M6×1 thread made of 1.4301 stainless steel (batch size 200,000) was significantly optimized. The use of the ZA16 thread cutting system with locking device eliminates the need for support, as the cutting forces of the four cutters cancel each other out.

Task

Application:

  • Special screw, thread M6×1


Material:

  • 1.4301 stainless steel (tensile strength 500–700 N/mm2)


Losgröße:

  • 200,000 pieces


Current process / customer request:

  • In the current process the workpiece must be supported
  • The component must be cut
  • Machining time approx. 10 seconds. A cycle time reduction of the thread cutting process is desired

Solution

  • Use of a ZA16 thread cutting system with closing device

Customer Benefit

Cost reduction:

  • Chasers can be reground

Process:

  • The component no longer needs to be supported, as it is centered by the four threaded chasers. The cutting forces cancel each other out.

Time saving:

  • Processing time approx. 8 seconds
  • The closing device closes the system during non-productive time
