Abstract
A numerically controlled grinding machine for grinding workpieces, such as tools, and other metallic or ceramic elements, comprises a machine bed (1) having fixedly connected to it a rigid, distortion-free portal (9) which has a reinforcing rear wall (13) rigidly connected to the machine bed, two side stands (10) and a horizontal bridge (11) which extends at a distance above the machine bed (1). A double wheel grinding spindle carrier (20) is adjustably mounted on the portal (9) for positioning along at least one axis (-y). The machine bed (1) projects at one side from the portal (9). The machine bed (1) supports a workpiece carrier movable about a plurality of axes.
Claims15
A numerically controlled grinding machine for precision grinding of workpieces, comprising:
- a machine bed;
- a workpiece carrier mounted to said machine bed;
- a grinding spindle carrier having a driven grinding spindle with a grinding wheel attached thereto;
- two side stands spaced from each other and fixedly connected to said machine bed;
- a bridge spaced by a given distance above said machine bed and fixedly connected to both of said side stands, said grinding spindle carrier being movably mounted to said bridge above and over said machine bed;
- a reinforcing and stiffening rear wall rigidly connected to said machine bed, said bridge and said two side stands to form an integral support unit for said grinding spindle carrier such that a frontally-open workspace is defined by said two side stands, said machine bed, said bridge and said rear wall into which said grinding wheel and said workpiece can extend from the front of said workspace to be controllably moved for carrying out the precision grinding.
