pintahiomakone

A pintahiomakone, also known as a surface grinder, is a machine tool used to produce a smooth, flat finish on a workpiece. It operates by using an abrasive wheel to remove material from the surface of the material being ground. This process is essential for achieving precise dimensions and a high-quality surface finish, especially in applications where flatness and accuracy are critical.

The grinding wheel, typically made of bonded abrasive grains, rotates at high speed. The workpiece is held securely on a magnetic chuck, a vise, or a fixture on the machine table. The table then moves back and forth, or reciprocates, under the rotating grinding wheel. Alternatively, some surface grinders have a rotating table onto which the workpiece is placed, and the grinding wheel moves vertically or horizontally. The depth of cut is controlled by the operator, who advances the grinding wheel incrementally to remove material.

Surface grinders are used in a wide variety of industries, including manufacturing, tool and die making, automotive, aerospace, and electronics. They are employed to grind flat surfaces on metal parts, such as machine components, molds, dies, cutting tools, and precision instruments. The ability to achieve very tight tolerances and a smooth finish makes them indispensable for creating components that require precise mating surfaces or aesthetic appeal. Different types of grinding wheels can be used depending on the material being ground and the desired finish.
