Rule it out for yourself.
Could it be a problem with the quality of the belt? It should be due to the belt being elongated, the positive pressure becomes smaller, and the friction is insufficient to cause the belt to slip, not due to the slippage that causes the belt to become longer. It may also be that the belt is a little too thick, try to change it to a thinner one.
1. Is there a relationship between the speed of the headstock of the cylindrical grinding machine and the speed of grinding the workpiece when working? The answer is yes. >>>More
Accuracy problem, the live center will use rolling bearings, rolling bearings will have clearance, and there are assembly problems in the live center, at least three parts in the assembly size chain (center, bearing, bearing mounting hole parts) size involved, the final result is that the rotary accuracy of the live center itself is not enough to meet the needs of the grinder, the dead center will not move, these errors will disappear, and finally the error of the 60-degree cone tip of the top is left into the system error. >>>More
I don't know much about how to start the head of the CNC cylindrical grinder. Not very clear.
The spindle accuracy of the M1432a with good accuracy should be achievable.
