The selection of lightweight and heavy-duty circling machines is mainly based on the size of the equipment being produced. Generally, lightweight small circling machines are mostly used for producing mesh materials such as small pet cages; The heavy-duty circling machine is mainly designed to facilitate the time-consuming circling of large equipment, with high efficiency and fast speed. It is a common small hardware processing equipment in production.

The principle of hydraulic pressure is widely used in many machinery and equipment, and it can rely on the action of pressure to achieve more functional purposes. And this pressure is a variable relationship that can be reasonably adjusted based on the actual situation. Hydraulic circle making machines have enormous value in many modern industrial production. Generally, the pressure of hydraulic circle making machines can be adjusted. So, how to implement the specific operation? Generally, the pressure is adjusted at the pressure reducing valve (relief valve) on the main outlet pipe of the oil pump. If it is already at its maximum, it depends on whether the pump is variable adjustable. Adjusting the pressure of the hydraulic ring punching machine according to the actual situation can achieve more free and stable results, which is of great help to industrial development and the improvement of the hydraulic ring punching machine itself.
