Definitions

  • Cutting tools are known whose cutting surface is covered by a Binding material and formed by abrasive cutting bodies is.
  • the abrasive cutting elements are in the binding material introduced in multiple layers and are through a sintering process firmly connected to the binding material.
  • the consistency of the binding material is similar to that to be processed Material adapted.
  • a Aggressiveness of the material to be processed Removal of the binding material causes and the rounded and / or worn abrasive cutting body can from the Binding material is loosened and / or destroyed.
  • Cutting body, that are in lower levels come through it used, and there is no need to sharpen the cutting tool.
  • the cutting tool can be used up to the cutting surface is used up.
  • cutting tools with one single-layer layer of abrasive cutting body an independent Resharpening not possible.
  • Such cutting tools are used especially with materials whose material aggressiveness unsuitable for removing the binding material is.
  • cutting tools for cutting tiles have an essentially single-layer abrasive layer Cutting body.
  • a device can be reached with the tools, and in particular tools with abrasive applied in one layer Cutting bodies whose abrasive cutting bodies are worn out are rounded off, simply and inexpensively processed and the tool life can be extended.
  • the above, worn or round cutting bodies broken and their Cutting behavior can be improved.
  • By breaking the above, worn abrasive cutting body can these are shortened and smaller, unused, sharp-edged abrasive cutting bodies can be made with a material to be machined come into contact.
  • the respective canceled Cutting bodies themselves have new sharp cutting edges, which also improve the cutting behavior.
  • abrasive cutting bodies Due to the generating rolling movement between the medium and the Tool can be used with a large surface pressure between the Means and the tool and with a small actuation force the abrasive cutting bodies are advantageously broken. Removing the abrasive cutting body from one Binding material of the tool can at least largely break be avoided. It is a manual operation of the device attainable with either the tool on the middle and / or the agent is rolled on the tool can.
  • the rolling movement between the medium and the tool can be achieved in different ways, for example with two plates that are translationally moveable and between which the tool can be clamped.
  • the agent is particularly advantageous from one to one Housing bearing rolling elements formed.
  • the device can be easily by hand by the operator around the tool and / or the tool can easily be hand or powered from a motor, for example from a hand machine tool motor, be rotated in the device.
  • the rolling element can be useful by various experts appearing components be formed, for example from one in a recess or on a bolt over one Plain roller bearing. Is the mean of an outer ring a rolling bearing can be advantageously inexpensive Standard components are used. It can be a storage can be achieved, which has a low friction, and an operator can operate the device with a small actuation force especially operate manually. Particularly advantageous sealed bearings are used for the bearings. The bearings can prevent the cutting bodies from abrasive wear be protected and it's long life the rolling bearing accessible.
  • At least three as are particularly advantageous in the housing Rolling elements trained means stored, their rolling surfaces limit a free space, at least one means in its Position through the jig to the other two means adjustable and thus the tool can be clamped in free space is.
  • the tool is in free space above the rolling elements in its Location advantageously fixable, and in particular can with three rolling elements a statically determined bracket of the Tool can be achieved.
  • the rolling elements can be used as clamping jaws the device used to hold the tool and the forces required for breaking or processing of the tool are required can be advantageous on the Rolling elements are introduced into the tool. It is one Device accessible, the universal to several, different large tools can be customized.
  • the means of which are radial are movably mounted outwards so that the means are radial outwards against an inner circumference of a tool, for example a hollow cylindrical tool, pressed and radially inward facing abrasives attached to the inner circumference Cutting body of the tool sharpened by means can be.
  • the housing has at least two housing parts that are movable relative to one another, which form part of the clamping device. The freedom can thereby designed to be easily adaptable to a tool become.
  • the two housing parts over at least an adjusting means are adjustable to each other. It is an advantageous translation can be reached via a small operating force a large clamping force between the Means and the tool can be achieved.
  • the actuating device can thereby of various ones which appear to be useful to the expert Means be formed, for example by an eccentric etc.
  • the actuating means is formed by a screw, can be an inexpensive and structurally simple Adjustment mechanism can be reached, through which the clamping force is exact can be adjusted.
  • the agent can be useful from various, to the expert appearing, particularly hard materials formed or with be coated with a particularly hard material, for example the agent can be formed from a hard plastic or the agent can have a ceramic layer or a diamond layer be coated etc.
  • this is advantageous Means made of hardened steel, creating a inexpensive construction can be achieved.
  • FIG. 1 shows a device for sharpening one in FIG. 4
  • Tile cutting tool 10 shown with one layer applied abrasive cutting bodies 12.
  • the device has a housing 24 and three means 14 mounted in the housing 24, 16, 18, wherein the housing 24 consists of a first housing part 40 and a second housing part 42.
  • the housing parts 40, 42 are on a first side to each other via a joint 46 pivoted and on one side opposite the first second side with each other via an adjusting means 44 connected.
  • the second housing part 42 projects with a molded web-like extension 72 into a cross section U-shaped region 74 of the first housing part 40, with the web-like extension 72 of the second housing part 42 and through the U-shaped region 74 of the first housing part 40 an aligned in the insertion direction 22 of the tile cutting tool 10 Bolt 30 is guided (Fig. 1 and 3).
  • the bridge-like Extension 72, the U-shaped region 74 and the bolt 30 form the joint 46.
  • the housing parts 40, 42 are formed by a screw Adjustment means 44 adjustable to each other and form one Part of a clamping device 20 (Fig. 1).
  • the positioning device 44 is perpendicular to the insertion direction 22 of the tile cutting tool 10 or in the pivoting direction of the housing parts 40, 42 passed through a bore 54 in the first housing part 40 and engages with its external thread in an internal thread of a hole 56 in the second housing part 42.
  • Rolling bearings 48, 50, 52 with parallel to the direction of insertion 22 of the tile cutting tool 10 extending axes of rotation stored, which have outer rings designed as rolling elements (Fig. 1).
  • the outer rings form the means 14, 16, 18, wherein in the clamped state of the tile cutting tool 10 a rolling movement between the outer rings and the tile cutting tool 10 can be generated.
  • the roller bearings 48, 50, 52 are sealed by seals 26, the balls 28 of the rolling bearings Protect 48, 50, 52 in particular from abrasive dust (Fig. 2).
  • the roller bearings 48, 50, 52 are arranged in the housing 24 in such a way that their axes of rotation have a triangular surface span, and their rolling surfaces 32, 34, 36 a free space 38 limit in which the tile cutting tool 10 in the insertion direction 22 is insertable.
  • the roller bearing 48 is in the housing part 42 mounted, and the roller bearings 50, 52 are in the housing part 40 stored, with the clamping device 20th or by a pivoting movement of the housing parts 40, 42 the Position of the roller bearing 48 to the roller bearings 50, 52 adjustable is.
