Notes on the use of roll grinding machine
When the roll grinding machine is running, attention should be paid to the contact between grinding wheel and the surface of workpiece. When the surface of the workpiece touch the grinding wheel, continuous sizzling sound can be heard, and the water traces on the surface of the workpiece can be taken away by the rotating grinding wheel, while a faint spark can be seen, coolant can be added at this moment.
Higher concentration of saponified liquid should be used, and must be strictly clean and filtered before use. Then feed, each time with 0.005 mm per double stroke. When the spark disappears, the grinding is completed. At this point, press the lateral feed handwheel in the direction of feed, so that the grinding wheel is slightly pressed into the workpiece, but no feed is made, in other words, to polish the workpiece once to further improve the quality of the grinding surface.
When grinding in high ambient temperatures (e.g. summer), the roll grinder's light should not be close to the workpiece in order to prevent the workpiece from heat expansion and affect the grinding quality.
If the surface of the workpiece is stretched, it means that the coolant is not clean or there is floating sand on the surface of the grinding wheel, so filter the coolant again or brush off the floating sand on the surface of the grinding wheel.
If the workpiece is partially burnt, it may be caused by insufficient coolant or excessive feed, or dulling of the grinding wheel.
If fine ripples appear locally on the surface of the workpiece after processing, it may be caused by spindle loosing, motor vibration or other reasons, which can be solved by taking corresponding measures according to the specific situation.
There are some other problem may happend during roll grinding machine running. Welcome to communicate with us.
