We all know that five-axis machine tools are a mode of CNC machine tool processing. This kind of machine tool is different from other industries. It mainly can greatly improve the processing efficiency of prismatic parts. It is precisely because of this that it is widely used in our important industries, such as aerospace, aviation and military, etc. are our important industrial elements! As an important industry, five-axis machining can be said to have a very large technical content, and it is also very difficult in terms of programming difficulty, and it is also very difficult in terms of machining accuracy. And how much do you know about the positioning accuracy of the rotary axis of the five-axis machine tool? Depending on the cost structure, customer requirements, and the processing conditions of the machine tool, specific rotary axes can be driven by torque motors or by servo motors and mechanical transmission systems. In the rotation axis, there are actually two that we need to understand! Next, let me briefly introduce it to you.

1. Semi-closed-loop control, many people don't know that in semi-closed-loop control, it is almost unnecessary to consider the error of mechanical transmission components. But its periodic load causes the transmission parts to heat up, so its positioning error is still relatively large to a certain extent. Even if the environmental conditions and processing conditions change, the machine tool needs to maintain the workpiece to meet the high-precision requirements, so the position information processing generally meets the requirements of measurement accuracy and long-term consistency.

2. Full-closed-loop control, what is full-closed-loop control, if the angle encoder is directly installed on the rotating shaft of the rotary table for position feedback.

To sum up, the above is my preliminary understanding of this product. If you want to know more, please call us for Xiehe Processing.
