At the heart of the technology is the hydraulic system on the machine, which controls the angle by controlling the rotating shear force and rotating speed of the machine. The machine's main motor can turn 360 degrees as needed; the hydraulic cylinder at the back of the shear can make the machine work at different angles, usually up to ±20 degrees. The operator can use the control lever to manually control the changes in the hydraulic system, so that the machine has a high degree of maneuverability, can carry out various types of work.

At the same time, because of the complex nature of the hydraulic drum cutter, it is necessary to have the corresponding electronic control system, which can accurately control each operation. Such control systems usually include numerical control systems and human-machine interfaces, which are used to control the timing and state of the machine's work. Some hydraulic drum cutters are also equipped with an automated operating system, which can automatically control the machine according to preset parameters and operating conditions, which can significantly improve the work efficiency, but also reduce the artificial misunderstanding of pavement lateral milling and digging machines.

The precise control of depth and angle of hydraulic drum cutter is mainly due to the hydraulic system, sensor and electronic control system on the machine. All the systems work together, so that the machine can complete the work quickly, stably and efficiently. At present, under the continuous promotion of new technology, the machine has appeared a more advanced multi-finger control scheme, which greatly improves the user experience and game feeling of some customers.
