"If you want to do something good, you must first strengthen its machine" in the Analects of this sentence, we must know that fully automated cnc machines are a kind of equipment that can achieve precision machining of high-precision, multi-batch, and complex parts. The whole equipment adopts the inclined layout, the bed is hollow structure, which greatly improves the bending and torsional rigidity of the machine tool in the work, and has high stability. The high rigidity and stability of the lathe provide a strong guarantee for the high precision of the machine tool processing.
(1) The operations that can be automatically ended include spindle speed change, positive and negative rotation, initiation or discontinuity, feed and rapid movement in two coordinate directions, release, rotation and clamping of the tool holder, switching of the cutting fluid, etc.
(2) The feed of the CNC turning tool is necessary to establish a connection with the rotation of the spindle, because the CNC lathe turning is calculated by the number of pulse equivalent of the turning tool moving along the feed direction when the spindle turns one circle.
(3) Since the specification and measurement of the part drawing standard are diameter values, in order to advance radial standard accuracy and facilitate programming and measurement, the X-direction pulse equivalent is taken as half of the Z-direction, so when the diameter direction is programmed with absolute value, the X coordinate value is indicated with the diameter value. When programming incrementally, program with 2 times the theoretical displacement of the radial, and attach a directional symbol.
(4) When processing parts, according to the needs of the surface quality and processing accuracy of the parts, the spindle is necessary to have a larger speed control plan, which can choose stable surface speed, and of course, can also choose stable speed.
(5) It has the function of tool compensation and the function of jump instruction.
(6) It is usually a two-coordinate machine tool to end the two-coordinate (X, Z) linkage processing of rotary induction parts.
(7) Due to the fully automated cnc machines processing parts of the blank commonly used wool and die forging, processing margin is large, so CNC lathes often have different methods of fixed cycle function, can carry out a variety of turning cycles.
