三、  工作原理

III. Working Principle

1、机械部分

1. Mechanical Part

双端面磨平机,双面磨平机 工作台的往复由电机带动变速箱，输出慢速带动丝杆工作，作逆旋转，丝杆螺母固定在工作台下面，从而带动工作台作往复移动。

The motor drives the transmission to output low speed to drive the screw rod to work in reverse rotation. In this way, the to-and-fro movement of work bench of double-end grinding machine (double-face grinding machine) is realized. Screw rod nuts are fixed under work bench to drive the bench move back and forth.

本机磨头是专业金刚石磨轮，直接安装在两台专用电机上，分别由两个横向工作台带动前进或后退，既可以自动，又可以手动。自动时将手柄向前推。手动时，将手柄向后拉即可。丝杠每一转为3MM。

This machine uses dedicated diamond grinding wheel directly mounted the two special-purpose motors that are respectively driven by the two horizontal bench, manually or automatically. In auto mode, the handle shall be pushed forward. In case of manual mode, the handle shall be drawn back. Every round of screw rod is 3mm.

工作台的标本夹具和两磨轮在本设备出厂前，经过精心调试，确保磨出的标本的垂直度与平行度。每次磨削两个平行面，六个面的立方体标本，只需要经过三次磨削成即可，每次要定位准确，这样磨出的试样才能达到要求。

Before leaving the factory, the sample fixture and two grinding wheels of work bench has been carefully debugged so as to ensure that the perpendicularity and parallelism of processed sample. Cubic samples with two parallel surfaces and six faces need only three times of grinding. For each grinding, the sample shall be accurately positioned. Only in this way, can the processed sample meet the requirements.

2、电器部分

2. Electric section

电气控制见电器原理图

See electrical principle diagram for electric control

双端面磨平机,双面磨平机控制的按钮分别安装在两个动力头上面，操作方便。因采用水冷却，水花飞溅，故本机电器采用36V的安全电压。由于电源电压、运行电机电压380V，所以本机必须进行可靠的接地，否则会产生安全事故。故电源不能接反，否则会损坏机器。

The buttons of double-end grinding machine (double-face grinding machine) are respectively mounted on the two power heads for convenient operation. Since water cooling may cause water splash, this equipment uses 36V safety voltage. This machine must be reliably grounded as the power supply voltage for motor is 308V; otherwise, safety accidents may occur. The power supply connection shall not be reverse since this may cause damage to the machine.
