Abstract
The invention discloses a method for grinding and machining a ball-nose end milling cutter and a four-axis coordinated grinding and machining device. In the grinding process, on the one hand the device leads a grinding wheel (8) to do rotary motion around a spindle and leads the ball-nose end milling cutter (9) to rotate around an axis X, on the other hand, the device leads the ball-nose end milling cutter (9) to translate along the axis X, at the same time, the device leads the ball-nose end milling cutter (9) to move along a horizontal axis Y which is vertical to the axis X and to move along an axis Z which is vertical to the axis X and the axis Y, thus forming the four-axis coordinated grinding and machining. The invention can clamp and grind as well as machine the ball-nose front knife surface and the circum front knife surface of the ball-nose end milling cutter in one time, thus realizing the grinding of all front and back knife surfaces on one special purpose machine tool. Compared with a five-axis coordinated machining center, one rotation axis is reduced in the grinding device of the invention, thus leading to simpler machine tool structure, ensuring precision among moving parts and effectively reducing the equipment cost.
