Product introduction of concrete core sample smoothing machine:
It adopts rebound single-phase series motor drive, gear reduction, round column guide, screw feed manual feed overall design, with small size, compact structure, simple operation, good grinding quality and so on. It is used to smooth the test specimens with core samples on site. The surface grinding head of the concrete core sample smoothing machine uses diamond cutting tools to achieve the grinding of the end face of the concrete core sample under the condition of high speed. Smooth and reliable.

Technical parameters of concrete core sample smoothing machine:
Third, the working principle of concrete core sample smoothing machine:
This machine relies on a surface grinding head equipped with a diamond cutting tool, and achieves the end grinding of the concrete core sample under the condition of the speed. ,reliable.
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
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.
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.
