Particularly, in the process of sudden stop and sudden rotation, the impact inertia generated by the self weight of the Z-axis whole body and the electric main shaft (grinding wheel working shaft) causes extra abrasion to the B-axis, and the long-term stable working precision of the equipment is influenced.
In addition, in the conventional five-axis linkage tool numerically controlled grinder, the X-axis sliding table slides relative to two parallel guide rails, and similarly, the Y-axis sliding table slides relative to the other two parallel guide rails. Because the upper ends of the existing guide rails are on the same horizontal plane. In the course of working, when receiving the power of toppling of strong bending, the X axle slip table and the crooked power of toppling that the Y axle slip table received of guide rail top are than great, take place deformation easily, influence the machining precision and the life of equipment.
There is therefore a need for improvement.
