Kessler milling spindles

Milling Spindles MILLING SPINDLES

The KESSLER milling spindles have a modular design.
 
Configure your own milling spindle model by specifying the installation position, motor,
speed, bearing, lubrication and sensory system – the perfect customized solution for your
individual branch and application needs.

KESSLER offers more: As an internationally successful company with extensive and highly specialized  expertise, we provide comprehensive advice about the design and manufacture of individual components and project management of complex system solutions. We use the very latest technology and analytical processes to test our components under realistic conditions, so that our products help your business to stay flexible and maintain its competitive edge.

Our in-house development division is supported by extensive calculation and analysis skills
and covers everything from drive technology to the construction of all-in-one systems.
Furthermore, optimized production and assembly lines provide the framework for stable processes
and the superior quality of our milling spindles.

Keeping up with the beat of the spindle

The KESSLER diaLOG intelligent system for data processing and condition monitoring is our solution for a connected industry

  • Integrated electrical current, temperature and vibration sensors determine the current, frequency, temperature conditions and vibration acceleration.
  • An intelligent digital network system (KESSLER diaLOG) analyses and evaluates process data.
  • Detects and stores exceeding marginal values
  • Interface with the network infrastructure or machine tool
  • Process data is forwarded to control systems in real time. The system for data transmission will be available in 2018 for TCP / IP or ProfiNET interface.
  • Predefined marginal values will permanently be controlled and monitored by the system. The diaLOG App has been developed for the evaluation of the diaLOG data.
  • Its functions are planned to include preventive maintenance and on-going data collection.
  • In future, correction factors will be conveyed from the motor spindle to the user and warning reports will automatically follow to the process control systems.
  • KESSLER diaLOG in the product, supports it being subjected to a complete process visualization.
  • Applicable in the whole product portfolio and other application areas possible.
KESSLER diaLOG - All advantages at a glance
  • Condition monitoring by detecting exceeding marginal values
  • Improved operational reliability in customer processes (Process performance, operation time)
  • Reduces TCO (Total Costs of Ownership)
  • Reduces machine downtime
  • Reduces unexpected downtimes
