Abstract

A cutting strand segment for a cutting strand of a machine tool separating device includes at least one blade carrier element, at least one blade element arranged on the blade carrier element, and at least one cutting depth limiting element arranged on the blade carrier element which is configured to limit a maximum cutting depth of the blade element to a value that is less than 0.5 mm.

First claim

The invention claimed is:

1. A cutting strand segment for a cutting strand of a power-tool parting device, comprising:
a cutter carrier element that includes:
a cutting element disposed on the cutter carrier element;
a cut-depth limiting element disposed on the cutter carrier element and configured to limit a maximum depth of cut of the cutting element to a value that is less than 0.5 mm;
a connecting recess disposed on the cutter carrier element; and
a connecting element integral with the cutter carrier element, the connecting element configured as a cylindrical stud fixedly extending from a coupling region of the cutter carrier element.

2. The cutting strand segment as claimed in claim 1 , wherein the cut-depth limiting element is configured to limit a maximum depth of cut of the cutting element to a value that is less than 0.3 mm.

3. The cutting strand segment as claimed in claim 1 , further comprising:
a transverse securing element disposed on the connecting element and configured to secure the cutter carrier element, when in a mounted state, against a transverse movement relative to a further cutting strand segment of the cutting strand.

4. The cutting strand segment as claimed in claim 3 , wherein the transverse securing element has at least one securing region that is at least substantially parallel to a cutting plane of the cutting element.

5. The cutting strand segment as claimed in claim 1 , the cutting strand segment having a maximum volume that is less than 20 mm 3 .

6. The cutting strand segment as claimed in claim 1 , wherein:
the connecting element defines a first central axis,
the connecting recess defines a second central axis,
a spacing of the cutting strand segment is defined as a linear distance between the first central axis and the second central axis, and
the spacing is less than 4.0 mm.

7. The cutting strand segment as claimed in claim 6 , wherein:
the cutting element defines a cutting plane,
a width of the cutting strand segment is perpendicular to the cutting plane, and
the width is less than 2.5 mm.

8. The cutting strand segment as claimed in claim 7 , wherein a width of the cutting strand is less than or equal to the width of the cutting strand segment.

9. The cutting strand segment as claimed in claim 1 , wherein:
the cylindrical stud defines a first diameter,
the connecting recess defines a second diameter, and
the first diameter is less than or equal to the second diameter.

10. The cutting strand segment as claimed in claim 1 , further comprising:
a segment guide element disposed on the cutter carrier element and including a transverse extension,
wherein the cylindrical stud defines a first longitudinal axis,
wherein the transverse extension defines a second longitudinal axis that is parallel to the first longitudinal axis,
wherein the cylindrical stud extends from the cutter carrier element in a first direction along the first longitudinal axis away from the cutter carrier element,
wherein the transverse extension extends from the cutting carrier element in a second direction along the second longitudinal axis away from the cutting carrier element, and
wherein the first direction is opposite the second direction.

11. A cutting strand for a power-tool parting device, comprising:
a first cutting strand segment that includes:
a first cutter carrier element having:
a first cutting element disposed on the first cutter carrier element;
a first cut-depth limiting element disposed on the first cutter carrier element and configured to limit a maximum depth of cut of the first cutting element to a value that is less than 0.5 mm;
a first connecting recess disposed on the first cutter carrier element; and
a first connecting element integral with the first cutter carrier element, the first connecting element configured as a first cylindrical stud fixedly extending from a first coupling region of the first cutter carrier element; and

a second cutting strand segment that includes:
a second cutter carrier element having:
a second cutting element disposed on the second cutter carrier element;
a second cut-depth limiting element disposed on the second cutter carrier element and configured to limit a maximum depth of cut of the second cutting element to a value that is less than 0.5 mm;
a second connecting recess disposed on the second cutter carrier element; and
a second connecting element integral with the second cutter carrier element, the second connecting element configured as a second cylindrical stud fixedly extending from a second coupling region of the second cutter carrier element,

wherein the first cylindrical stud is configured to be received by the second connecting recess to connect directly the first cutting strand segment to the second cutting strand segment.

12. The cutting strand as claimed in claim 11 , wherein the first cutting strand segment and the second cutting strand segment are rotatably connected together, such that the second cutting strand element is rotatable about the first cylindrical stud.

13. The cutting strand as claimed in claim 11 , wherein:
the first cutting strand segment further includes a transverse securing element disposed on the first connecting element and configured to secure the first cutter carrier element, when in a mounted state, against a transverse movement relative to the second cutter carrier element, and
the transverse securing element is stamped onto the first connecting element to connect directly the first cutter carrier element to the second cutter carrier element.

14. A power tool system comprising:
a portable power tool; and
a power-tool parting device supported by the portable power tool and having at least one cutting strand that includes:
a first cutting strand segment that has:
a first cutter carrier element with:
a first cutting element disposed on the first cutter carrier element;
a first cut-depth limiting element disposed on the first cutter carrier element and configured to limit a maximum depth of cut of the first cutting element to a value that is less than 0.5 mm; and
a connecting recess disposed on the first cutter carrier element; and

a second cutting strand segment that has:
a second cutter carrier element with:
a second cutting element disposed on the second cutter carrier element;
a second cut-depth limiting element disposed on the second cutter carrier element and configured to limit a maximum depth of cut of the second cutting element to a value that is less than 0.5 mm; and
a connecting element integral with the second cutter carrier element, the connecting element configured as a cylindrical stud fixedly extending from a coupling region of the second cutter carrier element,

wherein the cylindrical stud is configured to be received by the connecting recess to connect directly the first cutting strand segment to the second cutting strand segment.

15. The power tool system as claimed in claim 14 , wherein:
the power-tool parting device further includes at least one guide unit; and
the first cutting strand segment further includes at least one segment guide element disposed on the first cutter carrier element and configured to limit a movement of the first cutting strand segment away from the at least one guide unit along a direction that is at least substantially parallel to a cutting plane of the first cutting element.

16. The power tool system as claimed in claim 14 , wherein the portable power tool includes a coupling device configured to couple the power-tool parting device to the portable power tool in at least
