Axle drive by step motors and recirculating ball spindles (to avoid reversal backlash). For facing and longitudinal turning, for turning balls, radii and any freely formed contours made of steel and non-ferrous metal. Workpiece machining is effected automatically by software and can be reproduced as often as required. Solid, heavy cast iron bed and ground "wide-legged" precision Vee guide ensure vibration-free working and optimum precision.
Complete with recirculating ball spindles, powerful step motors and the required limit switches, the CNC control unit, all necessary connecting cables and the software on CD-ROM.
Since the mechanical design is practically identical to the PD 400, the accessories supplied for it can be used without restriction (and the PF 400 milling equipment).
The control unit as an interface between the CAD software and the CNC controlled lathe.
The CNC control unit is located in a solid aluminium casing and contains a micro processor and the output stages for the step motors.
It controls the step motors of both the axles drives and the drive for the main spindle using the PC data and, with two freely useable output relays, additionally offers the possibility to control an automatic cooling unit or signal display, for example.
The installed mains supply circuit makes it possible to connect directly to the 220 - 240 V mains voltage. The data transfer from the PC to the control unit is effected via an RS 232 interface. All connecting cables required to control the main spindle, the step motors and the limit switches are pre-assembled and equipped with suitable connectors, and are part of the scope of delivery.
If requested, the travel distances of the tool are simulated in the graphic window. In this way, faults in the programming can be recognised in time.
Simple creation of workpiece geometry
When the program is started, the CAD window initially appears on the screen. The contour of the workpiece is created in the usual Windows® environment.
In the graphic, colour elements help to show the difference between lathe chuck, blank and designed workpiece.
Comprehensive aids make it easier for the user to operate the program; in addition to use of the mouse, it also supports entry of co-ordinates (absolute and relative). It is possible to import existing files in the current data formats (e.g. dxf or hpgl).
Technology information is allocated to each character element. Various processing speeds and manual tool replacement are, for example, possible when machining the workpiece.
Automatic generation of CAM data
The finished drawing of the tool is converted, by a mouse click, into the instruction set for the machine. So, machining can be started immediately. The instruction set generated in this way is in accordance with DIN/ISO 66025 and can be manually edited and exported. Conversely, the system also permits importing or complete self writing of data sets.
Note:
