Description

A four-axis vertical CNC cutting edge equipment

technical field

The invention relates to a four-axis vertical numerical control cutting edge equipment.

Background technique

At present, the traditional knife-scissor machine is horizontal, and the grinding wheel only moves in the axial direction of the Z-axis. When the ordinary knife-scissor machine grinds a knife with a circular arc, the cutting point will be at the tail of the knife when viewed from the Z-axis direction. The tangent point of the arc starts to deviate from the center of the grinding wheel. The larger the arc, the greater the deviation from the center of the grinding wheel. At this time, it is more difficult to debug the machine, which requires higher technical level of technicians. The existing four-axis CNC single-sided grinding wheel only moves in the axial direction of the Z-axis, and a Y-axis with the workpiece for lifting is added, so that the cutting point of the workpiece is always kept at the center of the grinding wheel, but the workpiece is being processed In the process, it is necessary to swing at a certain angle. At this time, looking down from the Y-axis direction, the tangent point of the arc at the end of the knife gradually deviates from the contact surface of the grinding wheel. This is to be compensated by setting certain parameters on the Z-axis. That is to say, its grinding track is an irregular three-dimensional curve. There are many types of workpieces, different shapes and sizes, and different radians. It is difficult to grasp the compensation amount of the grinding wheel and difficult to program. After a certain workpiece is processed, each axis returns to a safe position, waits for the workpiece to be unloaded, installed, and then processed. This cycle continues, which takes a lot of waiting time and reduces work efficiency.
