三、  工作原理

III. Working Principle

1、機械部分

1. Mechanical Part

雙端面磨平機,雙面磨平機 工作臺的往復由電機帶動變速箱，輸出慢速帶動絲桿工作，作逆旋轉，絲桿螺母固定在工作臺下面，從而帶動工作臺作往復移動。

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.

本機磨頭是專業金剛石磨輪，直接安裝在兩臺專用電機上，分別由兩個橫向工作臺帶動前進或后退，既可以自動，又可以手動。自動時將手柄向前推。手動時，將手柄向后拉即可。絲杠每一轉為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.

工作臺的標本夾具和兩磨輪在本設備出廠前，經過精心調試，確保磨出的標本的垂直度與平行度。每次磨削兩個平行面，六個面的立方體標本，只需要經過三次磨削成即可，每次要定位準確，這樣磨出的試樣才能達到要求。

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、電器部分

電氣控制見電器原理圖

See electrical principle diagram for electric control

雙端面磨平機,雙面磨平機控制的按鈕分別安裝在兩個動力頭上面，操作方便。因采用水冷卻，水花飛濺，故本機電器采用36V的安全電壓。由于電源電壓、運行電機電壓380V，所以本機必須進行可靠的接地，否則會產生安全事故。故電源不能接反，否則會損壞機器。

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.
