Hydraulic CNC Shearing Machine

We are a professional shearing machine manufacturer with over 10 years of industry experience. Today, we would like to introduce to you the difference between CNC shearing machine and traditional shearing machine:

In the field of sheet metal processing, shearing machine as the basic processing equipment, its technical development has experienced the evolution from traditional mechanical to modern CNC. CNC shearing machine and traditional shearing machine in processing accuracy, operation and productivity, there are significant differences. Understanding these differences helps enterprises to make reasonable equipment selection decisions according to the actual production needs, improve production efficiency.

1, Control system differences

The traditional shearing machine mainly relies on mechanical transmission and manual operation. The operator manually adjusts the blocking mechanism and shear angle to complete the processing, the whole process requires more manual intervention and experience judgment. This control method requires a high level of operator skill, and the repeatability of processing parameters is poor.

CNC shearing machine adopts computerized digital control system. The operator only needs to input the processing parameters on the control panel, and the system will automatically complete all adjustments and processing. The CNC system can store hundreds of machining programs, which is convenient to call at any time, greatly reducing the difficulty of operation. At the same time, the system can also monitor the status of the equipment in real time and provide fault diagnosis function.

2, Comparison of processing accuracy

The processing accuracy of the traditional shearing machine is limited by the mechanical structure and the level of manual operation. In actual production, the shear length error is usually about ± 0.5mm, the angle error is about ± 1 °. Such accuracy for general processing needs can still be satisfied, but for high-precision products is not enough.

CNC shearing machine through the servo motor and precision ball screw to achieve accurate control. The shear length error can be controlled within ±0.1mm, and the angle error does not exceed ±0.5°. This high-precision feature enables it to meet the processing requirements of aerospace, precision instruments and other fields. The numerical control system can also automatically compensate for the error brought about by changes in the thickness of the plate to ensure processing consistency.

3, Comparison of production efficiency

The productivity of traditional shearing machine is low. Every time you change the processing specifications, you need to manually readjust the blocking position and tool clearance, which is time-consuming. A skilled operator can complete about 200-300 times a day specification switching, which to some extent restricts the production flexibility.

CNC shearing machines have significantly improved production efficiency through automation. Specification switching is done by selecting the appropriate program on the control panel, and the whole process can be completed within a few seconds. With automatic feeding device, CNC shearing machine can realize continuous mass production, the daily processing capacity can be up to 3-5 times the traditional equipment. This high efficiency characteristic is especially suitable for the modern production mode of multi-species and small batch.

4, safety performance analysis

The safety protection of the traditional shearing machine is relatively simple. Mainly rely on mechanical guards and two-handed operation buttons to ensure safety, the operator's safety awareness and operating standards have high requirements. In fatigue or improper operation, there are still certain safety hazards.

CNC shearing machine is equipped with perfect safety protection system. Including photoelectric safety protection device, emergency stop function, overload protection and many other safety measures. Some high-end models also use closed processing area, completely isolate the operator and moving parts, greatly reducing the risk of accidents. The intelligent system can also record the operation process, providing a basis for accident analysis.

5, maintenance requirements

Traditional shearing machine structure is simple, maintenance is relatively easy. Only regular lubrication and tightening of bolts are required on a daily basis, and fault diagnosis and repair are also relatively intuitive. However, due to the reliance on mechanical transmission, key components such as gears, clutches, etc., there is a certain degree of wear and tear, the need for regular replacement.

The maintenance requirements for CNC shears are more specialized. In addition to routine mechanical maintenance, you also need to regularly check the electrical system, sensors and other precision components. The software of the CNC system also needs to be upgraded in due course. Although maintenance costs are high, preventive maintenance can significantly extend the service life of the equipment and reduce the risk of sudden failure.

6, Applicable Scenario Suggestions

The traditional shearing machine is suitable for small and medium-sized enterprises with limited budgets, low product accuracy requirements and single varieties. Its price advantage is obvious, operation and maintenance are simple, and it is still widely used in sheet metal processing, construction steel and other traditional fields.

CNC shears are more suitable for modern production enterprises with high processing accuracy requirements and a wide range of products. Although the initial investment is large, but in the long run, its high efficiency and low scrap rate brings significant comprehensive benefits. Especially in automobile manufacturing, electronic equipment and other precision processing areas, CNC shears have become standard equipment.

CNC shears and traditional shears have their own characteristics and are suitable for different production needs. Enterprises should consider product requirements, production scale, capital budget and other factors when choosing. With the development of intelligent manufacturing, CNC shears will be more powerful and easier to operate, which is an irreversible technological trend in the metal processing industry. Understanding the difference between the two types of equipment will help enterprises grasp the direction of technological development and make wise purchasing decisions.
