drill cnc machine is widely used in the power equipment manufacturing industry. Energy issue is a strategic issue of ******, our country has always paid attention to the manufacturing of electric power equipment. After decades of development, China's power equipment manufacturing level has ranked in the forefront of the world, China's electrical equipment manufacturing enterprises can meet the development needs of smart grid. The development of related power equipment manufacturing machine tools has also gone to a higher level.

The precision indicators of drill cnc machine are generally divided into: positioning accuracy and repeated positioning accuracy; Resolution and pulse equivalent; Indexing accuracy. Positioning accuracy refers to the degree of the actual moving position of the drill cnc machine workbench and other moving parts and the command position, and the inconsistent difference is the positioning error. The factors causing positioning errors include servo system, detection system, feed transmission and guide rail errors. Positioning errors directly affect the dimensional accuracy of machined parts. Repeated positioning accuracy refers to the consistency of the results obtained after several specified operations are completed under the same operation mode and conditions. Repeated positioning accuracy is generally a normal distribution of accidental errors, which will affect the consistency of batch machining parts. Is a very heavy performance indicator. The general positioning accuracy of the drill cnc machine is 0.018mm, and the repeated positioning accuracy is 0.008mm.

Resolution and pulse equivalent: Resolution refers to the smallest displacement gap that can be resolved. For the measurement system, the resolution is the smallest displacement that can be measured, and for the control system, the resolution is the smallest displacement increment that can be controlled. The pulse equivalent is the amount of displacement generated by the displacement parts of the machine tool when the exponential control device does not send a pulse signal.

Indexing accuracy: Indexing accuracy refers to the difference between the actual rotation Angle and the command rotation Angle when indexing the table. The indexing accuracy not only affects the angular position of the machining parts in space, but also affects the coaxial degree of hole processing.
