山东智拓讲解数控开料机精度如何选择？

导读：众所周知，同步带都有必定张紧力，运用时间长了，或多或少会导致精度下降，而数控开料机关于机器的精度要求适当严格，因而各种配件都要合理分配才可。

数控开料机工作一般是重负荷高精度：

其特征在于将负载移动所需的扭矩往往远超过伺服马达自身的扭矩容量，而透过减速机来做伺服马达输出扭矩的进步，便可有用处理这个问题。

进步扭矩：

输出扭矩进步的方法，可能选用直接增 大伺服马达的输出扭矩方法，但这种方法不光有必要运用贵重大功率的伺服电机，马达还要有更健六面钻壮的结构，扭矩的增 大正比于操控电流的增 大，此刻选用比较大的驱动器，功率电子组件和相关机电设备标准的增 大，又会使操控系统的本钱大幅添加。

添加运用功率：

理论上，进步伺服马达的功率也是输出扭矩进步的方法，可藉由添加伺服马达两倍的速度来使得伺服系统的功率密度进步两倍，并且不需要添加驱动器等操控系统组件的标准，也就是不需要添加额定的本钱，而这就需透过行星减速机的分配来到达进步扭矩的目的了，所以说，高功率伺服马达的开展是有必要分配使用减速机，而非将数控六面钻其省掉不必。

进步运用性能：

据了解，负载惯量的不妥匹配，是伺服操控不稳定的zui大原因之一，关于大的负载惯量，可以使用减速比的平方反比来分配的等效负载惯量，以取得好的操控呼应，所以从这个视点来看，行星减速机为伺服使用的操控呼应的匹配

添加设备运用寿命：

行星减速机还可有用处理马达低速操控特性的衰减，因为伺服马达的操控性会因为速度的下降，导致发生某程度上的衰减，尤其在关于低转速下的信号撷取和电流操控的稳定性上，特别简单看出，因而，六面钻厂家选用减速机能使马达具有较高转速。 

下降设备本钱：

从本钱观念，假定0.4KW的AC伺服马达分配驱动器，需消耗一单位设备本钱，以5KW的AC伺服马达分配驱动器有必要消耗15单位本钱，但是若选用0.4KW伺服马达与驱动器，分配一组减速机就可以到达前述消耗15个单位本钱才能完结的事，在操作本钱上节约百分之50以上。因而运用者依其加工需求不同，决定选用的行星齿轮减速机产品，一般来说，在机台工作上有低速，高扭矩，高功率密度场合需求，绝大部分选用行。

板材木工机械设备材质：

在开料中产用的板材有密度板和刨花板，这两种板材硬度比较高，但是由于成本低和易加工等原因被广泛应用板式家具生产当中，但是这两种板材拥有同一个缺点，那就是这两种板材都是压制而成，意思就是它们并不是一个总体，粘结力度不强的话，开料的时候就容易崩边。

解决办法：

板材的选择可能使我们无法改变的，但是我们可以选择好的数控木工开料机，比如数控开料机，崩边的状况主要出现在推台锯和质量差的开料机中，智拓数控开料机不会出现因为设备原因产生的崩边。

As we all know, the synchronous belt has a certain tensioning force, the use of a long time, more or less will lead to a decline in accuracy, and the CNC cutting machine precision requirements are appropriately strict, so all kinds of accessories should be reasonably distributed.

CNC cutting machine work is generally heavy load high precision:

Its characteristic is that the torque required to move the load is often far more than the torque capacity of the servo motor itself, and the progress of the output torque of the servo motor through the reducer can be useful to deal with this problem.

Progressive torque:

The output torque improvement method may choose to directly increase the output torque method of the servo motor, but this method is not only necessary to use a valuable high-power servo motor, the motor also has a more robust six-sided drilling structure, the increase in torque is proportional to the increase in the control current, at this moment, the choice of a larger driver, power electronic components and related mechanical and electrical equipment standards. It will greatly increase the cost of operating the system.

Add operating power:

In theory, the power of the progressive servo motor is also the output torque improvement method, by adding twice the speed of the servo motor to make the power density of the servo system improve twice, and do not need to add the driver and other control system components of the standard, that is, do not need to add the rated cost, and this needs to be distributed through the planetary reducer to achieve the purpose of progressive torque. Therefore, the development of high power servomotor is necessary to allocate the use of reducer, rather than cutting out the CNC six-sided drilling.

Improved performance:

It is understood that the improper match of the load inertia is one of the biggest reasons for the instability of the servo control, about the large load inertia, you can use the inverse square ratio of the deceleration ratio to distribute the equivalent load inertia, in order to obtain a good control response, so from this point of view, the planetary reducer for the servo use of the control response match

Add equipment service life:

The planetary reducer can also be used to deal with the attenuation of the motor's low-speed control characteristics, because the control of the servo motor will be due to the decrease in speed, resulting in a certain degree of attenuation, especially in the stability of signal acquisition and current control at low speed, which is particularly simple to see, therefore, the six-side drilling manufacturers choose the deceleration function to make the motor have a higher speed.

Descent equipment cost:

From the concept of cost, it is assumed that 0.4kW AC servo motor to allocate the drive, need to consume a unit of equipment cost, 5KW AC servo motor to allocate the drive is necessary to consume 15 units of cost, but if 0.4KW servo motor and drive, allocate a group of reducers can reach the above-mentioned consumption of 15 units of cost to complete the matter. More than 50 percent savings in operating costs. Therefore, the user decides to choose the planetary gear reducer product according to its processing needs, in general, there are low speed, high torque, high power density occasions on the machine work, most of the choice of line.

Plate woodworking machinery equipment material:

Density board and particleboard are used in the cutting middle board, the hardness of these two boards is relatively high, but due to low cost and easy processing and other reasons are widely used in the production of panel furniture, but these two boards have the same disadvantage, that is, these two boards are pressed, meaning that they are not a whole, bonding strength is not strong, if the board is not strong, it is not a good way to make it. It's easy to crack when you start cutting.

The solution:

The choice of the plate may make us unable to change, but we can choose a good CNC woodworking opener, such as a CNC opener, the situation of edge collapse mainly appears in the push table saw and poor quality of the opener, the intelligent extension CNC opener will not appear because of equipment reasons.
