Control - Turnstar 300 C - CNC Horizontal Lathe
GPlus 450 Drehen
GPlus 450 - Windows-based CNC control for lathes
- The GPlus 450 features a 17“ TFT color monitor with touch-screen display to display all data for a user-friendly programming experience and easy operation
- Status messages show the user the current state of the control
- Frequently used machining sequences can be programmed quick and easy using the graphics-based Cycle Editor.
- With the use of Input masks, the Cycle Editor guides the operator intuitively and self-explanatory through the editing steps. A separate Help Graphic is available for every definable parameter
- Knowledge about the G and M Code Command Set or special programming language are NOT needed. However, experienced users have the ability to use DIN/ISO programming to create NC programs.
- Graphic simulation with integrated zoom function for a detailed display of actual chip removal
- A standard 10/100 MBit Ethernet interface and USB port allow fast data transfers from externally created programs (CAD/CAM) and saving these on the GPlus 450 hard drive
- single CPU concept (advantage: ties up only 2% of the system capacity)
- 40 GB storage, 2.0 GHz Intel Celeron processor, 256 MB RAM
- block processing time: 450 NC blocks per sec
- worldwide remote diagnostics
- Profibus, CANopen, DeviceNet implementation is possible
- machine can be integrated in factory networks
- technology-specific cycles for turning
Cycle overview T (Turning):
- plain turning, facing, taper turning, radius turning, plunge-cut, recessing forms E and F, thread turning, multiple thread turning, contour turning
Why PC Technology?
- PC Technology serves as platform for high-performance CNCs, since it allows us to automatically take part in the development programs of leading manufacturers of motherboards, hard drives, software, and operating systems. Thus, these manufacturers provide us with an "extended workbench". The rapid development of these components gives the KNUTH GPlus 450 a special edge.
- Optionally, the GPlus 450 software may be installed on a regular office PC (System Requirements: Intel processor) whereby the user interface is fully identical with the machine control user interface. This allows for a very realistic operation and programming training of newcomers. The created NC programs can be tested and simulated and are fully executable on the machine's control.
Maximized PC power results in optimized speed, surface quality, and accuracy of the machine tool and ensures high dynamics and ease of use. This makes the GPlus 450 ideally suited for a large variety of machining technologies, e.g. turning. Programming of technology-specific machining cycles is quick and easy; therefore, this control can be used for both single part and small batch productions.
The portable hand control unit features an ergonomic design with two Acknowledge buttons (safety enable). The machine axes can only be moved, if one Acknowledge button is activated. Two rotary selector switches are provided for axis selection and feed speed setting. Additionally, the hand control unit is equipped with an emergency stop button, an electronic hand-wheel and machine-dependent function keys to simplify machine set-up.
