Here I will introduce some problems and solutions for the universal grinder.
1. When the spindle rotates, the sound is loud. The main shaft sounds very loud, mostly due to misalignment of the bearing, or the loosening of the screw against the spindle. When we encounter this problem, we should replace the spindle or tighten the screw.
2. When the switch is turned on, the motor will not turn. We must first check the circuit if we encounter this kind of problem. If it is a broken switch, we will replace the switch. If it is a line problem, we will have to check the circuit.
3. After starting the belt, the belt slides off automatically, and the belt slides off due to the looseness of the belt. The distance between the two pulleys should be adjusted to tighten the belt.
4. The worn tool has a taper. When this problem occurs, we should adjust the scale on the tool head so that the tool head is perpendicular to the spindle. These are some of the solutions to problems that I have provided for everyone, and I hope to solve the worries of customers who use grinders.
Aromatic Compound, any of a large class of compounds that includes benzene and compounds that resemble benzene in certain of their chemical properties. Originally applied to a small class of pleasant-smelling chemicals derived from vegetables, it now encompasses a wide diversity of compounds with no connection to the sense of smell. Common aromatic compounds other than benzene include toluene, naphthalene, and anthracene (all of which are present in coal tar). Each of these compounds contains at least one ring that consists of six carbon atoms, each joined to at least two other carbon atoms, and each joined to adjacent carbon atoms by one single and one double bond. The resulting hexagonal structure is characteristic of many aromatic compounds
