Cutting rotating tool

The innovation concerns a cutting rotating tool.

During the industrial production of profiles from or in wood, metal, plastic and so on, machining is used rotating tools in Fori.i of rasps, milling cutters, Files and the like used, the cutting edges of which are arranged on the circumference and have a profile that corresponds to each corresponds to the profile to be manufactured. For industrial mass production it makes sense for a specific desired Profile to make a correspondingly profiled tool, which can be formed in one piece, for example. Such Four tools are quite expensive and only when used in mass production profitable.

When different types of profiles are to be produced in small numbers - for example in small workshops or for do-it-yourselfers - the purchase of one is corresponding in each case profiled tool too expensive.

Task of innovation int it, for such tasks cutting, rotating VJerkzeu / * to create the manufacture many different profiles using a relatively small number of tool elements.

This task is -'according to the innovation '¹; solved by a mandrel, one end of which is designed to be clamped into the machine chuck and on the other end of which several nit axial bores of corresponding diameters urr -vn " ^τ -, Γ ^η :: with cutting edges, rotationally symmetrical v: - ■ ■ ^';; th ^ RSER rush "or rasps clamped sir' ..

The innovation is to be explained in more detail below with reference to the attached drawing. The drawing schematically illustrates a side view of the tool gemä.1 the innovation, marked with cut eil for clarity of illustration, the items to ^rn.

The mandrel Io is up to a collar 12 with its clamping shank 14 can be seized into the chuck of a drive machine, for example a hand drill. On the spanning 16, which is provided with a bolt thread, up to four cutting Tool elements are attached. To this end There are washers 18 in front of and behind the tool elements or 2o and a nut 22 to be screwed onto the mandrel are provided. Instead of the washers, SpreM ^ inge be used; and optionally snap ring can also be used or washers are used between the individual tool elements. For greater distances between the individual A spacer disk 24 is provided for tool elements.

The rasps 2o and 2 ° · in the shape of a cylinder and the rasps 3o and 32 with a 45 cone are shown as examples of different tools. They are provided with a rasp, file, pocket or teeth cut on the circumference. The tool elements can be clamped in any combination - •. ^R ground; it goes without saying that, for example, only one tool element can be clamped and used on its own Rasps formed with concave or convex profiles 2 5a, 2 ^p yes, 3oa and 32 a. But with the four rasps 2o, 28,3o and 32 most of the profiling operations common to wood (grooving, cutting, toothing and so on) can be carried out ) perform,;.
