Portable Milling Device and Method

Abstract

Provide a milling device that can be used flexibly. 【Solution means】In a milling device 10 for forming a recess in a workpiece, a contact device 6 having a contact structure 8 including a first structural part 9 and a second structural part 11 that statically contact the workpiece simultaneously during the formation of the recess, wherein the second structural part 11 is supported so as to be rotatable relative to the first structural part 9 and can be fixed relative to the first structural part 9 at a plurality of different rotational positions, said contact device; an electrical positioning device formed to move a milling tool 17 relative to the contact structure 8 along positioning degrees of freedom 31, 32, 33; an electronic control unit formed to control the electrical positioning device according to motion information so that the milling tool 17 performs a rotary cutting motion to form a recess are included.
