FAQ Retrofit B-Flex

Control Conversion for Contour Cutting Machines

B-Flex Retrofit - what exactly is behind this Bäumer service? We have summarized the most frequently asked questions of our customers and created an information portal that provides you with all the important details of B-Flex.

What is B-Flex?

B-Flex is a control conversion for Bäumer’s contour cutting machine types OFS and HFS.

Which machines can be converted according to B-Flex?

  • OFS-201; OFS-202; OFS-212; OFS-221; OFS-222
  • OFS-HE; OFS-HE3; OFS-HT; OFS-Twincut

Why did Bäumer introduce B-Flex?

Product life cycles for electronic components are considerably shorter today. The supply of spare parts for older components is becoming increasingly difficult, even for well-known suppliers such as Lenze, Siemens, etc.
To prevent production downtimes, Bäumer offers a new control cabinet to replace the old one.

What is included in the retrofit?

1. An entirely new control cabinet, extensively tested at Bäumer before delivery
2. A new industrial PC with the following specifications:

  • New Windows 10 loT Enterprise 2019 LTSC 64-bit
  • 21.5’’ screen
  • Intel Core i5 6440EQ CPU board
