Proxxon 24500 Precision Lathe PD400/CNC

 

The Proxxon lathe PD 400 with CNC control. Multi-purpose for individual parts and small series manufacture.

Axle drive by stepper motors and recirculating ball screws to avoid backlash. For facing and longitudinal turning, for turning balls, radii and any freely formed contours made of steel and non-ferrous metals. Workpiece machining is effected automatically by software and can be reproduced as often as is required. Solid, heavy cast iron bed and ground precision vee guide ensure vibration-free working and optimum precision. Since the mechanical design is practically identical to the PD 400, the accessories supplied for it can be used without restriction.

Complete with recirculating ball spindles, powerful stepper motors, and the required limit switches, the CNC control unit, all necessary connecting cables and the software on CD-ROM.

The CNC control unit is located in a solid aluminium casing and contains a micro processor and the output stages for the stepper motors. It controls the stepper motors of both of the axes drives and the main spindle using the PC data and, with two freely controllable output relays, 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 220-240V mains voltage. The data transfer from the PC to the control unit is effected via RS-232 interface. All connecting cables required to control the main spindle, the stepper motors and the limit switches are pre-assembled and equipped with suitable connectors, included with the delivery.

When the software 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 the lathe, the chuck, the blank and the workpiece. Comprehensive aids make it easy for the user to operate the software. In addition to the mouse, manual coordinate entry in relative and absolute modes is supported. It is also possible to import existing files in the current data formts such as AutoCAD DXF and HPGL. Various processing speeds and manual tool replacement are possible, for example when machining different parts of the same workpiece.

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 accordinace with DIN/ISO 66025 and can be manually edited and exported. Conversely, the system also permits importing or writing your own data sets.

If requested, the travel distances of the tool can be simulated in the graphics window. In this way, faults in the programming can be recognised before cutting. The handwheels are replaced with high precision step motors, however manual machining is still possible, since the step motors can be operated using buttons in the software.

PROXXON CAD/CAM software for WINDOWS


The software is harmonized with mechanics, motors and the control unit of the CNC machine, thus offering the optimum performance. 

The CNC control unit controls the step motors of the machine. The PC software provides the machine with the geometry information for travel of the tools (via RS 232 interface). This means that the control unit is the interface between software and the mechanics of the machine. 

Powerful micro processors and accordingly dimensioned step motors and phases ensure that the motors always provide enough power for any machining processes. Two freely usable output relays in the casing of the control unit provide facilities for control of additional functions, e.g. a working lamp. Including connection cables with suitable plugs and built-in power supply for connection to 220 - 240V.
 

Simple creation of work piece geometry 
The CAD window is displayed when the programme starts. The work piece contour is created in the familiar WINDOWS® environment. Numerous auxiliary aids help during programme operation, which supports both coordinate entry (absolute and relative) in addition to mouse use. 

Technology information is allocated to every drawing element. This makes, for example, different processing speeds and manual tool replacement possible. 
Read-in of existing files in .dxf format is possible as well.

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. 


Software update for precision lathe PD 400/CNC

CNC simulation
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. 

Manual work
The handwheels are replaced with the step motors of the CNC machine. Nevertheless, manual machining is possible with the help of cursor buttons, since the step motors can be operated manually. 

Software installation
The PC software is supplied on a CD ROM. The problem-free installation is effected under WINDOWS® as usual.

Note:
PC or laptop are not part of the scope of delivery. Minimum requirements for the hardware: Pentium processor with 400 MHz frequency (or comparable), high-quality graphic card (64 MB RAM) and at least 40 MB free hard disc storage.
