Vertical Turning Center of NC

New SINUMERIK 802D CNC system on the use of more than 10 years of SKIQ16 CNC B Vertical Turning Center of NC, NC Machine Tool powerful features greatly broadened the scope of machining parts, and better ensuring the processing of parts the consistency and quality of products. This article was the second SINUMERIK NC application essay activities and the transformation of a prize-second prize.

KIQ16 CNC B Vertical Turning Center in the Czech HULIN companies in the 1990s manufacture, use FANUC-BASK 6T CNC system. Since the machine had been in use for more than 10 years, and the NC system upgrading, BASK 6T-FANUC CNC system has been shutdown, system board of aging, expensive spare parts. A new CNC machine tools to transform the system is imperative so that the machine can restore vitality, and give better play to the potential of machine tools.

Transformation programme development

The original full-featured machine, including spindle (table) and the rotation axis milling campaign, X, Z-axis coordinates of movement, 15 knives in a knife library systems, and such as the cooling system, hydraulic system, lubrication system , Paixie system functional machine. Spindle axis and milling by DC and DC motor speed regulator. X and Z-axis also coordinates by DC servo motor and DC servo governor. The knife used ordinary three-phase asynchronous AC motor from the five binary cam positioning. The mechanical part of the machine all good mechanical properties of stability, accuracy fair and normal hydraulic system, the part of the capital remain unchanged.

NC system and the replacement of electrical control part, by SIEMENS SINUMERIK 802D CNC system. X and Z axes and knives coordinates the servo drive system uses SIIMODRIVE 611UE variable frequency drive system and a FK7 servo motor, encoder pulse chosen as a location detection devices, digital servo drive system to achieve closed-loop control. And milling spindle axis drive system by the British company's 590 + Eurotherm Series DC motor speed control device. Machine control of other electrical lines, the replacement of electrical control devices to ensure

that all kinds of machine control function and operation of the realization of the electrical control machine tools guarantee a long-term reliable work.

Apart from increasing MCP machine control panel, we must also re-designed machine operator panel with all types of machine function buttons and lights. NC system and the servo drive system coordinates

SIEMENS SINUMERIK 802D CNC system is all CNC, PLC, HMI and communications tasks integration, is based on the NC system of PROFIBUS. Maintenance-free hardware integration PROFIBUS interface used to drive and I / O module and installed a speed of the operation panel. SINUMERIK 802D CNC control system X, Z axes and knives to the three figures into a spindle axis and. The machine used two I / O modules and machine operator panel PP72/48 MCP. TOOLBOX 802D use in PROGRAMMING TOOL PLC 802 software development PLC control procedures, call the subroutine library PLC SBR32 PLC-INI PLC initialization, SBR33 EMG-STOP exigency stop processing, transmission SBR34 MCP-802D machine control panel corresponding I / O status, NCK-SBR38 MCP MCP machine control panel signal, signal sent to the operation panel HMI NCK interface, SBR39 HANDWHL from the operation panel HMI in the machine coordinates or workpiece coordinate system selection hand wheel, SBR40 AXIS-CTL Feed spindle axis and enable control. The subroutine is the standard lathe control procedures, and so different from the actual situation of the machine, the digital knife-axis, an increase of the number of digital axis. In the machine control panel and feed axis and the spindle can control subroutine will be done in certain modifications. Vertical Turning Center unlike ordinary horizontal lathe, coordinates a different direction, it is also necessary to do subroutine amended accordingly.

SIIMODRIVE 611UE variable frequency drive system is a function of the drive system can be configured with SINUMERIK 802D CNC system constitutes an ideal combination. SIIMODRIVE 611UE variable frequency drive system in the machine to meet the dynamic response and speed adjustment range and rotation accuracy characteristics of the requirement to use modular design can be optimized to best independent state. Debugging can drive on a PC using SimoCom U or use of the front of the driver modules for display and keyboard. SimoCom U can be set using drives
