Problems solved by technology

However, the generally curved work surface is not suitable for every type of round workpiece or groove
Furthermore, the curved working surface is usually very small, which clearly limits the range of applications of such grinding blocks

Embodiment Construction

[0094] The processing apparatus 10 includes a processing body 20 at the outer periphery of which a plurality of processing surfaces 21 , 22 and 23 are provided. The schematically indicated workpiece W can be machined, for example ground and / or polished, on its workpiece surface O by means of the machining surfaces 21 - 23 . The working surfaces 21 - 23 extend on the outer circumference 24 of the per se cylindrical working body 20 . The processing body 20 has a longitudinal profile and extends along a longitudinal direction or a longitudinal axis L. As shown in FIG.

[0095] The machining surface 21 is provided as a flat surface 25 or flat surface with which a correspondingly flat workpiece surface O can be machined optimally. The working surface 21 or the planar surface 25 is arranged on a working surface part 28 , which is designed by means of the planar surface 25 as a planar surface part 26 .

[0096] In contrast, the working surfaces 22 and 23 are curved working surfaces...

Abstract

The invention relates to a surface machining apparatus (10), in particular a manual grinder, comprising a machining member (20) that has at least one machining surface (21-23) for grinding or polishing a workpiece surface (O); the machining member (20) includes a planar surface portion (26) with a planar machining surface (21) for machining planar workpiece surfaces (O) and at least one curved portion (27) with a curved machining surface (22-23) for machining curved workpiece surfaces (O). The curved portion (27) on said machining apparatus (10): extends across a side of the machining member (20) that lies opposite the planar surface portion (26), has a plurality of curved sections (31-36) which adjoin each other without interruption and each of which has a different radius of curvature (R1-R5), and does not protrude beyond the planar machining surface (21-23) of the planar surface portion (26).

Description

technical field [0001] The invention relates to a surface processing device, in particular a manual grinding device (or grinding device, i.e. Schleifgerät) or polishing device, with a processing body having a tool for grinding or polishing the surface of a workpiece. At least one processing surface, wherein the processing body has a flat surface part and at least one curved part (or called a curvature part, i.e. Krümmungspartie), the flat surface part has a flat processing surface for processing a flat workpiece surface, the at least one The curved portion has a curved machining surface for machining a curved workpiece surface. Background technique [0002] Such machining devices are known, for example, as grinding blocks (or grinding blocks, ie Schleifklötze). With the aid of the flat machining surface, the operator has the possibility of machining flat bases or workpieces, while the curved machining surface is optimally suited, for example, for grinding or polishing elong...
