Production Machine

CEDRAT TECHNOLOGIES  has already demonstrated that mechatronic solutions create high added value in manufacturing processes while being cost effective. Our customers are 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. 

Our mechatronics components 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 our 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

Active Chips breaker using APA® and SA75D

Advanced materials for extreme applications are more difficult to machine: Super-alloys, hard, brittle, ductile, multi-structure or composite CFRP materials. The requirements for part geometry profiles follow the same evolution in complexity as manufacturing processes improve.

Cedrat Technologies provides Plug & Play smart tool holders and embedded actuation solutions for the generation of additional vibrating energy in the manufacturing process. This association increases the removal / forming rate, improves process quality, increases tool life, saves energy and makes possible complex machining. Whereas controlled low frequency vibrations already address cutting / forming applications, high frequency & ultrasonic solutions provide an innovative approach in extrusion and chemistry processes.

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, poorfinish, 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.

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.
