数控加工中心 必须满足以下四个条件:
CNC machining center must meet the following four conditions:
一、加工中心位置环境要求加工中心的位置应远离振源、应避免阳光直接照射和热辐射的影响,避免潮湿和气流的影响。如数控机床附近有振源,则加工中心四周应设置防振沟。否则将直接影响数控机床的加工精度及稳定性,将使电子元件接触不良,发生故障,影响加工中心的可靠性。
1、 The location environment of machining center requires that the machining center should be far away from vibration source, avoid the influence of direct sunlight and thermal radiation, and avoid the influence of humidity and air flow. If there is a vibration source near the CNC machine tool, the anti vibration groove should be set around the machining center. Otherwise, it will directly affect the machining accuracy and stability of CNC machine tools, make the electronic components in poor contact, cause failure, and affect the reliability of the machining center.
二、电源要求一般加工中心安装在机加工车间,不仅环境温度变化大,使用条件差,而且各种机电设备多,致使电网波动大。因此,安装加工中心的位置,需要电源电压有严格控制。电源电压波动必须在允许范围内,并且保持相对稳定。否则会影响加工中心数控系统的正常工作。
2、 Power requirements of general machining center installed in the machining workshop, not only the environmental temperature changes greatly, the use of poor conditions, and a variety of mechanical and electrical equipment, resulting in large fluctuations in the power grid. Therefore, the installation position of machining center needs strict control of power supply voltage. The fluctuation of power supply voltage must be within the allowable range and keep relatively stable. Otherwise, it will affect the normal work of CNC system of machining center.

三、温度条件数控加工中心的环境温度低于30摄示度,相对温度小于80%。一般来说,数控电控箱内部设有排风扇或冷风机,以保持电子元件,特别是中央处理器工作温度恒定或温度差变化很小。过高的温度和湿度将导致控制系统元件寿命降低,并导致故障增多。温度和湿度的增高,灰尘增多会在集成电路板产生粘结,并导致短路。
3、 Temperature condition: the environment temperature of NC machining center is less than 30 degree, and the relative temperature is less than 80%. Generally speaking, there are exhaust fans or air coolers in the CNC electric control box to keep the working temperature of electronic components, especially the CPU constant or the temperature difference changes little. Too high temperature and humidity will reduce the life of control system components and increase the number of faults. With the increase of temperature and humidity, more dust will bond on the integrated circuit board and lead to short circuit.
四、按说明书的规定使用加工中心用户在使用加工中心时,不允许随意改变控制系统内制造厂设定的参数。这些加工中心参数的设定直接关系到加工中心各部件动态特征。只有间隙补偿参数数值可根据实际情况予以调整。
4、 When using the machining center according to the instructions, users are not allowed to change the parameters set by the manufacturer in the control system. The setting of these machining center parameters is directly related to the dynamic characteristics of machining center components. Only the gap compensation parameters can be adjusted according to the actual situation.
