In order to achieve higher precision cutting movements, the motion control of high precision machine tools generally uses higher level functional components.

In terms of guideways and bearings, high-precision machining requires high-precision and smooth positioning movements, trajectory movements and small distance movements, so it is more common for high-precision machining machines to use hydrostatic screws and hydrostatic guideways. In addition, electric spindles for high precision machining machines can also take the form of dynamic or hydrostatic bearings to achieve both support and cooling functions and to improve the stiffness and damping performance of the spindle.

In terms of position control, as precision measurement is a prerequisite for controlling high precision machining, to ensure that the movement of the machine tool reaches the required level of accuracy, the measurement accuracy of the electronic ruler must be 1~2 orders of magnitude higher. At present, high-precision processing machine tools generally use a resolution of 0.05 ~ 0.1μm glass encoder. Machine tool accuracy, finish and tool life are directly proportional to the rigidity of the machine tool, so high precision machining machines pay particular attention to the design and material selection of the bed.

The bed material is ductile iron and, after optimisation by finite element analysis, the bed has a static stiffness of 120 N/μm, three times higher than the average CNC machine, and a high frequency dynamic stiffness two to three times higher than the average machine. In addition, the bed of the JIG series is supported at three points and the peripheral systems such as tool magazines, electrical cabinets and pallet changers are separated from the bed, which not only simplifies the installation of the machine, but also improves the stability of the machine and reduces bed chatter.
