混凝土双面磨平机工作原理：

★机械部分

1、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。

2、本机磨头是**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。

3、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。

★电器部分

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。

Third, the working principle of double-sided concrete grinder

★ Mechanical part

1. The double-end smoothing machine and the double-side smoothing machine are reciprocated by a motor driven gearbox. The output speed drives the screw to work in reverse rotation. The screw nut is fixed below the table to drive the table to reciprocate .

2. The grinding head of this machine is a ** diamond grinding wheel, which is directly installed on two special motors, which are driven forward or backward by two horizontal tables, which can be automatic or manual. Push the handle forward when auto. When manually, pull the handle backward. Each turn of the screw is 3MM.

3. The specimen holder and two grinding wheels of the workbench are carefully adjusted before the equipment leaves the factory to ensure the verticality and parallelism of the ground specimen. Grinding two parallel and six-sided cube specimens at a time only requires three grindings, and the positioning must be accurate each time, so that the ground samples can meet the requirements.

★ Electrical parts

The double-side smoothing machine and the double-side smoothing machine control buttons are respectively installed on the two power heads for easy operation. Due to the use of water cooling and water splashing, the electrical appliances of this machine use a safe voltage of 36V. Because the power supply voltage and running motor voltage are 380V, the machine must be reliably grounded, otherwise a safety accident will occur. Therefore, the power supply cannot be reversed, otherwise the machine will be damaged.

混凝土双面磨平机操作规程：

★接通电源及水源。

★根据芯样直径选择相应的夹具，将芯样夹紧并转到底盘中位置后将夹具索紧。

★松开上、下索紧手轮，转动升降手轮，当磨轮端面距芯样端面1mm时停止。然后索紧上索紧手柄，开启进水嘴阀门通水，并闭合电源开关，使磨轮转动，然后逆时针转动手轮，并同时顺时针转动微动手轮使磨头下降。当磨轮端面接触试样端面时摆动磨头进行磨削，直至磨平试样端面。

★磨削完毕，关闭电源及水嘴阀并逆时针转动微动手轮，使其处于上**限位置。

★松开夹具索紧手柄，将夹具同试样一同取下并反向安装，重复2、3、4步动作磨削另一端面。直至芯样端面符合要求为止。

★磨平机用后关闭电源，擦试干净机器

Fourth, the operating rules of concrete double-sided smoothing machine:

★ Turn on the power and water.

★ Select the corresponding clamp according to the core sample diameter, clamp the core sample and turn it to the center of the chassis, and then tighten the clamp.

★ Release the upper and lower ropes to tighten the handwheel, turn the lifting handwheel, and stop when the end surface of the grinding wheel is 1mm from the end surface of the core. Then fasten the tight handle, open the water inlet valve to allow water, and close the power switch to rotate the grinding wheel, then turn the hａnd wheel counterclockwise, and at the same time turn the micro-movement hａnd wheel clockwise to lower the grinding head. When the end surface of the grinding wheel contacts the end surface of the sample, the grinding head is swung to perform grinding until the end surface of the sample is flattened.

★ After grinding, turn off the power and the water nozzle valve and turn the micro-motion handwheel counterclockwise to make it in the upper limit position.

★ Release the clamp and tighten the handle, remove the clamp together with the sample and install it in the opposite direction. Repeat the steps 2, 3 and 4 to grind the other end surface. Until the core sample end meets the requirements.

★ Turn off the power after smoothing the machine, try to clean the machine

混凝土双面磨平机注意事项：

★每次装夹标本应将夹具及样本表面冲洗干净，否则残留物质会使标本磨削精度下降，每次定位要准确。

★自动磨削的任何时候都不能随意手动进给，否则会损坏磨轮和设备，只有手动时才能手动进给。

★自动磨削结束后，先停工作台，后停磨头。

★磨削过程中应注意冷却液流量是否充足

V. Precautions for double-sided concrete smoothing machine:

★ Each time the specimen is clamped, the fixture and the sample surface should be washed clean, otherwise the residual material will reduce the grinding accuracy of the specimen, and each positioning must be accurate.

★ Do not feed manually at any time during automatic grinding, otherwise the grinding wheel and equipment will be damaged, and manual feeding can only be performed when manual.

★ After the automatic grinding is finished, stop the workbench first, then stop the grinding head.

★ Pay attention to whether the coolant flow is sufficient during grinding
