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、操作規程；

★接通電源及水源。

★根據芯樣直徑選擇相應的夾具，將芯樣夾緊并轉到底盤中位置后將夾具索緊。

★松開上、下索緊手輪，轉動升降手輪，當磨輪端面距芯樣端面1mm時停止。然后索緊上索緊手柄，開啟進水嘴閥門通水，并閉合電源開關，使磨輪轉動，然后逆時針轉動手輪，并同時順時針轉動微動手輪使磨頭下降。當磨輪端面接觸試樣端面時擺動磨頭進行磨削，直至磨平試樣端面。 4、磨削完畢，關閉電源及水嘴閥并逆時針轉動微動手輪，使其處于上 限位置。 5、松開夾具索緊手柄，將夾具同試樣一同取下并反向安裝，重復2、3、4步動作磨削另一端面。直至芯樣端面符合要求為止。 6、磨平機用后關閉電源，擦試干凈機器

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、注意事項：

★芯樣端面磨削要求質量高，為了防止工作發生振動，磨平機工作時應放在地質較硬的地方，并仔細調正地腳螺釘使底盤放平

★磨輪在磨削中會產生較高熱量，為了保證磨輪的使用壽命，嚴禁在無水情況下進行磨削。

★水源應該有足夠的水壓，在水壓較低時，當磨輪旋轉后水流會因受到阻力，磨輪部位會無水噴出。此時可用水管直接將水噴在試件磨削平面上，以保證正常工作。

★在磨輪A次使用時或當磨輪金鋼石顆粒磨鈍，使削磨發生困難時可用耐火太磚或砂磚待磨輪端面有金剛石顆粒露出即可)。

★芯樣裝在夾具上，應使芯樣兩端面露出長度相同為宜。當一端磨好后反向磨削另一面時，不應松動夾具緊固螺絲以保證芯樣兩端的平行度與端面與軸線的垂直度。

★混凝土磨平機在使用現場應有可靠的接地裝置，以防意外事故發生。

★混凝土磨平機用后應擦拭干凈。

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.
