1、 How to choose the accuracy of CNC cutting machines?

1. CNC cutting machines generally work with heavy loads and high accuracy

Its characteristic is that the torque required to move the load often exceeds the torque capacity of the servo motor itself. By improving the output torque of the servo motor through a reducer, this problem can be effectively addressed.

2. Progressive torque

The method of improving output torque may be to directly increase the output torque of the servo motor. However, this method not only requires the use of expensive high-power servo motors, but also requires a more robust hexagonal drilling structure. The increase in torque is proportional to the increase in control current. At this moment, the use of larger drivers, the increase in power electronic components and related electromechanical equipment standards, will greatly increase the cost of the control system.

3. Add applied power

In theory, improving the power of a servo motor is also a method of improving output torque. By adding twice the speed of the servo motor, the power density of the servo system can be increased by two times, and there is no need to add drivers or other control system components, which means there is no need to add rated cost. This requires the distribution of planetary reducers to achieve the goal of improving torque. Therefore, The development of high-power servo motors is necessary to allocate the use of reducers, rather than eliminating the need for CNC hexahedral drilling.

4. Improve application performance

It is understood that improper matching of load inertia is one of the biggest reasons for unstable servo control. Regarding large load inertia, the inverse square of the reduction ratio can be used to allocate the equivalent load inertia to achieve good control response. Therefore, from this perspective, the planetary reducer is a matching match for the control used by the servo.

5. Add equipment service life

Planetary reducers can also effectively handle the attenuation of low-speed control characteristics of motors, as the controllability of servo motors may experience some degree of attenuation due to a decrease in speed. Especially in terms of signal acquisition and current control stability at low speeds, it is particularly easy to see. Therefore, the use of reducers by hexahedral drilling manufacturers can enable motors to have higher speeds.

6. Reduce equipment costs

From a cost perspective, assuming that a 0.4KW AC servo motor distribution driver consumes one unit of equipment cost, it is necessary to use a 5KW AC servo motor distribution driver to consume 15 units of cost. However, if a 0.4KW servo motor and driver are selected, and a set of reducers is allocated, the aforementioned task of consuming 15 units of cost can be achieved, saving more than 50% of operating cost.

2、 Materials and Solutions for Woodworking Machinery and Equipment

The boards used in the cutting process include density board and patterned board. These two types of boards have relatively high hardness, but are widely used in the production of panel furniture due to low cost and easy processing. However, these two types of boards have the same drawback, which is that they are both pressed, meaning they are not a whole. If the bonding strength is not strong, they are prone to edge collapse during cutting. The selection of boards may be difficult for us to change, but we can choose good CNC woodworking cutting machines, such as CNC cutting machines, where edge breakage mainly occurs in push table saws and poor quality cutting machines. Nowadays, the use of CNC cutting machines is becoming increasingly common. Below is an introduction to the reasons why the plates processed by CNC cutting machines may have burrs

1. Sharpness of cutting tools

CNC cutting machines use cutting tools to cut materials, and the sharpness of the cutting tools indirectly affects the roughness level of the cutting surface. If the sharpness level of the cutting tool is not strong, the sheet metal that is cut in will show edge collapse. It is not recommended to cut the material too fast in case of poor tool condition.

Generally speaking, due to different manufacturing processes, the impurities in multi-layer boards are much less than those in Chuanghua boards. However, in the process of selecting boards, one should also be cautious and choose a supplier with stable quality. The damage to cutting tools is small, the damage to equipment can delay the construction period, and even the industrial accident has a big story. Therefore, the selection of sheet materials is crucial. It is generally recommended to use TCT three blade cutting straight knives for multi-layer boards.

2. Plate material

The boards used for production in the cutting process include density board and patterned board. These two types of plates have relatively high hardness, but they have the same problem, which is that they are both pressed, which means they are not a whole. If the bonding strength is not strong, it is likely to collapse during cutting.

3. Spindle speed

The same principle applies to the sharpness of the cutting tool. If the spindle speed is not enough, the boards inserted by the cabinet cutting machine may exhibit edge cracking. When adjusting the spindle speed to a high point, it is necessary to pay attention to adjusting within the range that does not affect the utilization of the tool.

4. The tool clamping is not sturdy

The tool clamping of the CNC cutting machine is not sturdy, which can cause edge collapse of the plate and damage to the tool during the processing of the product.

5. Poor consequences of vacuum adsorption

The vacuum adsorption table of some cutting machines is not very strong in terms of adsorption ability, and the workpiece is not firmly adsorbed during the processing of products, resulting in the displacement of the board and causing the board to collapse.
