Difficulty in internal grinding
◆The size of the wheel used in internal grinding is usually considerably small. The amount of wheel and work in contact at the point of internal grinding is larger than that of other grinding method,which tends to shorten wheel life.。
◆Wheel wear has a tendency to occur, which contributes to be difficult in maintaining the grinding accuracy.
◆Most of workpieces are required to be precise. Therefore, if the wheels are not suitable for applications, we can not get sufficient operation accuracy.
