The development trend of machine tools

Machine tools are currently shifting in several major directions, starting with the increase in the use of 5-axis machines and multi-tasking machines. 5-axis machining machines and multi-tasking machines began to appear on the market around the second half of 1990, and are now widely used in the market. Features include grinding, machining, and workpiece handling robots in addition to cutting. In addition, there is now a trend to further increase the number of control axes, a tendency to be more complex. Second, the machine tool becomes easier to operate. For example, the function of automatically correcting the mechanical thermal displacement in the machine is set in the machine tool; the function of checking the mutual interference between the grinding tool and the workpiece; the function of monitoring the state of the spindle in operation (involving temperature, vibration, displacement, etc.); and the intelligence of the device Chemical. These changes will make the machine easier to operate. Then there is the development of machine tools to high precision and micromachining. This improves the performance of components such as a DD motor or a linear motor, and makes it possible to determine the position accuracy of the sub-precision stage. In addition, the machine tool has become more space-saving. At present, the requirements for high performance of compact machines for high-volume production lines are also significant. In order to further suppress the width of the device and improve its maintainability, a 5-axis processing machine with a device width of 1000 mm is now available. The last point is that machine tools are moving in the direction of reducing environmental load. There are many machine tools that are designed to recognize environmental problems in the market, such as the reduction of air flow in oil and gas lubrication and the switching from oil and gas lubrication to grease lubrication.
