Main configuration and requirements of machine tool numerical control system and electrical system
• CNC system:
Using Taiwan Baoyuan special high-grade CNC system to achieve four-axis three linkage.
• Number of control axes:
Z axis: longitudinal movement of the table
X-axis: the transverse feed motion of the milling cutter holder
C- axis: rotary motion of headstock spindle
A- axis: automatic rotation of the milling cutter holder
Among them, C and Z are linked to realize thread movement; electronic handwheel is configured to manually control the movement of each CNC axis of the machine tool.
• CNC system function
1) Compensation function: reverse clearance compensation, lead screw pitch error compensation;
2) Feed function: fast feed, precision feed. Feed rate adjustment (per minute/per revolution)
3) Minimum pulse quantity: linear axis 0.001mm, rotation axis 0.001 °.
• Configuration of remaining major electrical components
1) The protection grade of the electrical control cabinet is IP54, equipped with wall-mounted industrial air conditioner, and the lighting lamp and power socket for maintenance are installed in the electrical cabinet;
2) Power cables and signal cables are installed separately to avoid electromagnetic interference and ensure reliable operation of the control system.
