Fourth, the use of concrete core sample smoothing machine:

★ Turn on the power and water source of HMP-150 concrete core sample smoothing machine.

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

★ 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 lower the grinding head. When the end surface of the grinding wheel contacts the end surface of the sample, the grinding head is swung for grinding. This continuously lowers the grinding wheel until the end face of the sample is flattened.

★ After grinding, turn off the power and water valve. Keep it in the upper limit position.

★ Release the gripping cable and tighten the handle, remove the gripper together with the test piece, and press in the opposite direction. Repeat 2, 3, and 4 to grind the other end surface. Until the core sample end meets the requirements

五、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。 4、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。 5、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。 6、磨平机用后关闭电源，擦试干净机器

Fifth, the operating rules of the concrete core sample 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. 4. After grinding, turn off the power and the water nozzle valve and turn the micro-handwheel counterclockwise to make it in the upper limit position. 5. Loosen 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. 6. Turn off the power after using the smoothing machine and try to clean the machine.

六、注意事项：

★芯样端面磨削要求质量高，为了防止工作发生振动，磨平机工作时应放在地质较硬的地方，并仔细调正地脚螺钉使底盘放平

★磨轮在磨削中会产生较高热量，为了保证磨轮的使用寿命，严禁在无水情况下进行磨削。

★水源应该有足够的水压，在水压较低时，当磨轮旋转后水流会因受到阻力，磨轮部位会无水喷出。此时可用水管直接将水喷在试件磨削平面上，以保证正常工作。

★在磨轮A次使用时或当磨轮金钢石颗粒磨钝，使削磨发生困难时可用耐火太砖或砂砖待磨轮端面有金刚石颗粒露出即可)。

★芯样装在夹具上，应使芯样两端面露出长度相同为宜。当一端磨好后反向磨削另一面时，不应松动夹具紧固螺丝以保证芯样两端的平行度与端面与轴线的垂直度。

★混凝土磨平机在使用现场应有可靠的接地装置，以防意外事故发生。

★混凝土磨平机用后应擦拭干净。

6. Matters needing attention for concrete core sample smoothing machine:

★ The grinding of the core end face requires high quality. In order to prevent the work from vibrating, the flattening machine should be placed in a hard geological place when working, and the foundation screws should be adjusted carefully to level the chassis.

★ The grinding wheel generates high heat during grinding. In order to ensure the service life of the grinding wheel, it is strictly forbidden to carry out grinding in the absence of water.

★ The water source should have sufficient water pressure. When the water pressure is low, when the grinding wheel rotates, the water flow will be subject to resistance, and there will be no water spray from the grinding wheel. At this time, the water pipe can be used to spray water directly on the grinding surface of the test piece to ensure normal work.

★ When the grinding wheel is used for a time or when the diamond particles of the grinding wheel are blunt, which makes grinding difficult, you can use refractory or sａnd bricks until the diamond particles on the end face of the grinding wheel are exposed).

★ The core sample is mounted on the fixture, and the two ends of the core sample should be exposed at the same length. When one end is ground and the other side is ground in the opposite direction, the clamp fastening screws should not be loosened to ensure the parallelism of the two ends of the core sample and the perpendicularity of the end surface and the axis.

★ Reliable grounding device should be used on the concrete grinder to prevent accidents.

★ The concrete grinder should be wiped clean after use.
