CNC Units

Computerized numerical control (CNC) unit, the brain of Sodick's product.
A CNC unit extracts the best performance of Sodick's products as an excellent control tower.


About CNC Units

Background of DevelopmentA CNC unit, or a computerized numerical control unit, controls the motion of a machine tool, a robot or the like based on numerical information and servo mechanism.
Sodick holds the industrial property rights to copy and use the technology for producing CNC units (including display and input devices) capable of controlling up to eight axes simultaneously and the software for numerical control of high-speed milling centers.
Main Features

  • HEIDENHAINCNC control units, developed on the basis of Sodick-made PCs, capable of flexibly coping with different machining methods.
  • Use of a high-resolution scale leads to enhanced accuracy in detecting position (a resolution of 0.03 μm) and velocity.  This improves high-gain reactivity and maintains high accuracy at high machining speeds.
  • High-speed and high-precision machining based on look-ahead control (Sodick Enhanced Precision Technology - SEPT) enables selection of an optimum machining condition for each phase of rough finish machining by changing parameters using NC programs.
  • A newly added HD device enables one-action reading, execution and edition of large NC programs, realizing 3-D die forming.

Background of Development

Control
Control
A CNC unit plays the role of fully extracting the performance of a machine.
The history of Sodick's CNC technology began with the idea of "providing an electrical discharge machine with a CNC unit to control its motors as desired".  It was necessary for realizing high-quality machining to have a CNC unit that was specially designed for an electrical discharge machine and capable of fully and delicately controlling the motors based on numerical data, and the best way to achieve this without compromising with accuracy was to develop CNC units in-house.  Sodick's CNC units enable unparalleled ultra-fine and high-quality machining because they are designed specifically to fully extract the capabilities of Sodick's machines.  What is more, since the hardware of the CNC units was developed based on a PC, the CNC units can be made to adapt flexibly to various kinds of machine tools by developing a man-machine interface and application software suitable for each of them.
