Mechatronic solutions create high added value in manufacturing processes while being cost effective. Particularly for customers like advanced machine manufacturers, machine-tool builders, tool makers, spindle suppliers and end users willing to optimize advanced metal cutting, metal forming, extrusion and chemical processes.
Mechatronics components from Cedrat Technologies such as actuators, sensors, drivers and controllers, are specifically designed for manufacturing environments. They are extra flat, powerful and precise and are traditionally used in harsh, heavy duty and high temperature environments. In addition the motional and sensing performances cover a wide dynamic bandwidth.
Starting from diagnostic services, mechatronic systems are designed to be Plug & Play Products or integrated as OEM versions in new machines. The scope of solutions is not limited to engineering work, they offer the opportunity of large-scale industrial cost-effective products. The projects of today are the smart products of tomorrow.
VIBRATION ASSISTANCE
VIBRATION DAMPING
Milling, turning, grinding and drilling processes are limited by chatter vibrations related to the flexibility of the machine tool structure. Such vibrations reduce cutting speeds to well below the capacities of machines or tools. They also result in noise, poor finish, unacceptable tolerances and sometimes tool breakage.
Parasitic vibrations are removed by installing intelligent damper units on existing or new machines. Our solution can be supplied in a Plug & Play format for immediate effect or fully integrated.Typical chatter vibration reductions over [1Hz-1kHz] are [-10dB;-20dB]. Improved stability of the process is observed in all cases.
Operation - Process | Solution | Benefit |
---|---|---|
Heavy roughing operations. Milling machine | Active damping Solution Embedded into spindle head | Cutting capability is doubled Improved stability is observed |
Longitudinal turning steel slender bar Lathe machine | Semi active work-holding device Active Plug & Play tool holder | Reliability is improved +20% higher feed rates |
FAST & PRECISE POSITIONING
Long and slender parts are distorted during machining. Cutting and forming conditions may also vary during the machining process without being observed and controlled. An additional cutting axis may be necessary to produce complex parts. These distortions lead to inacceptable inaccuracies and decreaseprocess flexibility.
The solution passes through a sensory and active fixture system which detects distortion and controls active repositioning of the clamp achieving the desired part geometry and tight tolerances.
