Working principle of SHM-200 concrete double end face grinding machine

1. Mechanical part

The reciprocating motion of the worktable is driven by a motor and a gearbox, which outputs a slow speed to drive the screw rod to rotate left and right, forming a reciprocating motion of the worktable

The grinding head of this machine is a dedicated diamond grinding wheel, which is directly installed on two dedicated motor spindles. It is driven forward or backward by two horizontal workbenches, which can be automatic or manual. When automatic, the handle is turned to the automatic position, and the clutch is engaged. When the workbench moves forward, the collision is difficult. The pawl pushes the ratchet wheel to make intermittent motion, and the ratchet wheel drives the screw to rotate through the clutch, so that the grinding head moves forward. When manual, the handle is turned to the manual position, and the screw rotates 0.025mm per square and 3mm per rotation.

The specimen fixture and two grinding wheels on the workbench are carefully calibrated before leaving the factory to ensure the perpendicularity and parallelism of the ground specimens. Two parallel faces and six faces of cubic specimens are ground each time, and only three rounds of grinding are required by this equipment

2. Electrical part

The control buttons of this machine are installed on the two power heads for easy operation. Due to the use of water cooling, the splashing of water is severe. Therefore, the electrical control of this machine adopts a safe voltage of 36V, and there will be no leakage caused by water during operation.

Operation steps of SHM-200 double end grinding stone machine

1. Clamp the good sample block, pay attention to symmetry on both sides, and tightly adhere to the fixture

2. Pull out the two grinding heads until the sample block does not hit the grinding wheel when the worktable moves,

3. Install the protective cover and turn on the water source switch

4. Press the main power button

5. Activate the grinding head button to rotate the grinding head in the direction of the arrow, and reverse rotation is never allowed

6. Press the workbench button

7. Manually feed the grinding head for grinding. If it needs to be automatic, turn the wrench to the automatic position and grind the two grinding heads separately. After grinding, turn the handle to the manual position and repeat the grinding several times to ensure the smoothness of the specimen

8. Grind the back grinding head properly
