1. High flexibility and complex process The movable CNC gantry milling machine has the characteristics of high flexibility (variability) and complex process. The so-called “flexibility” is flexible, versatile and flexible, and can adapt to automated machine tools for processing workpieces of different shapes. The development of the movable CNC gantry milling machine has blurred the concept of roughing and finishing processes, breaking the traditional process boundaries and separate processing process rules, which can maximize the efficiency of equipment utilization. Gantry milling machines can generally complete drilling, boring, reaming, plane milling, bevel milling, slot milling, surface milling (cam), tapping and other processing. Moreover, in general, the required machining operations can be completed in one clamping.
2. The machining accuracy of the moving table CNC gantry milling machine is high. The pulse equivalent of the current CNC device (that is, the movement of the slide plate after each pulse is issued) is generally 0.001mm, and the high-precision CNC system can reach 0.0001mm. Under normal circumstances, the workpiece can be guaranteed. Machining accuracy, in addition, CNC machining can avoid the error of manual operation, the size uniformity of a batch of processed workpieces is relatively good (including the uniformity of the main size of the workpiece and chamfering and other dimensions), and software can also be used for accuracy correction and compensation , greatly improving the product quality.
3. The time required for high production efficiency parts processing includes maneuver time and auxiliary time. The movable CNC gantry milling machine can effectively reduce this part of the time, so the processing productivity is much higher than that of the general milling machine. The good structural rigidity allows the powerful cutting of the large cutting amount of the movable table CNC gantry milling machine, which effectively saves the maneuvering time. The fast movement and positioning of the moving parts of the CNC milling machine adopts acceleration and deceleration measures, so a high idle travel speed is selected, and the time consumed in fast forwarding, fast rewinding and positioning is much less than that of ordinary milling machines. The spindle speed and feed of the movable CNC gantry milling machine are infinitely variable, so it is beneficial to choose the best cutting amount.
4. Reduce the labor intensity of the operator. The machining of the parts is automatically completed by the movable CNC gantry milling machine according to the pre-programmed program. Except for operating the keyboard, loading and unloading the workpiece, intermediate measurement and observation of the machine tool movement, heavy repetition is not required. Manual operation can greatly reduce the labor intensity. Because the CNC milling machine has the above unique advantages, the movable CNC gantry milling machine has become the main equipment in the machinery manufacturing industry. However, the programming operation of the moving table CNC gantry milling machine is more complicated, and the quality of the programming personnel is relatively high. Otherwise, it is difficult to play the role of CNC milling machine.
