Description

Description Title: Diamond grinding wheel with cutting inserts.

Field of application: The invention relates to a diamond grinding wheel with cutting inserts for machining hard materials made of metal, ceramics or plastic, especially for profile grinding.

Purpose: Grinding wheels are bodies of revolution, which with relatively high Speeds run, these must with a large safety factor the centrifugal forces that occur and absorb cutting forces.

The safety regulations must therefore be observed with priority.

The cutting material -diamond- in a small broken condition Diamantboart is expensive.

The cutting inserts enable a desired combination of highest security with economical occupancy with Diamantboart.

By replacing existing cutting inserts, one should wear out grinding wheel that has become unusable can be made usable again.

Background Art: It is known to manufacture diamond grinding wheels in which a layer of diamond board all over the perimeter and on Is brought to end faces on a base body made of metal.

The attachment of the diamond board on the base body is done by Pressing in, electroplating, sintering, gluing or mechanical fitting of the Single grains reached.

With diamond saw blades, which are to be regarded as very narrow grinding wheels are, narrow cuts are known to interrupt the circumference.

This makes thermal stresses in the base body ineffective.

Criticism of the state of the art The grinding specialist is used to the final required accuracy and profile accuracy through a suitable dressing process on the grinding wheel itself.

What about using grinding wheels made of aluminum oxide or silicon carbide is possible without further ado, must naturally occur with a diamond-coated grinding wheel encounter difficulties, as diamond is the hardest material there is.

While the manufacturer of diamond grinding wheels from normal shapes Stock can deliver, a profiled grinding wheel always means a special production.

Worn diamond grinding wheels have to be regenerated by the manufacturer himself will.

There is no possibility that the user can simply exchange them of missions can do this himself at short notice.

Task: The invention is based on the task, in deviation from the all-round t) iq jacket grinding wheel, just with a large number to grind diamond-coated inserts and thus comply with the safety regulations to make the production easy and the interchangeability of these inserts enable.

Solution: According to the invention, this object is achieved in that a grinding wheel base body made of metal or another suitable material on its circumference with grooves is provided, which for receiving the carrier material or in another case serves to accommodate the interchangeable inserts.

Further embodiment of the invention: The shape of the grooves is designed so that the forces that occur - cut, centrifugal and lateral forces with great certainty be included.

It can be a "Te" keyhole or a dovetail slot. Wide grooves can be designed in the well-known Christmas tree shape.

The grooves are parallel to the grinding wheel axis or inclined to the Axis incorporated.

They can be worked into smch straight or curved.

The cutting inserts can even be made of castable material in the grooves or plastically deformable material are formed in the grooves themselves.

The cutting inserts are for certain groove shapes and grinding profiles prefabricated, there are the interchangeable cutting inserts.

Diamantboart is pressed, troweled into the work surface, sintered or galvanically applied.

Achievable Advantages: The advantages that can be achieved with the invention are The diamond grinding wheel with cutting inserts guarantees high functional reliability even at high peripheral speeds, the amount of space required for occupancy Diamantboarts is about a fifth of an all-round diamond grinding wheel.

This grinding wheel is therefore also efficient for profile problems small quantities.

Under favorable circumstances, this grinding wheel is made by the user himself manufacturable.

Exchangeable cutting inserts allow the regeneration of a worn grinding wheel in the workplace.

The interrupted cut during the grinding process increases the grip and with it the performance of this disc.

Heat generation harmful to the workpiece is interrupted Cut greatly reduced.

Claims (1)

requests for permission: Generic term: 1. Diamond grinding wheel with cutting inserts, identifying Part: especially for the prefil grinding, characterized in that in a rotation body made of metal, ceramic or solid plastic with the shape of well-known Grinding wheels or grinding tools are incorporated on the working side, which accommodate the diamond grit-bearing cutting inserts. Generic term of the sub-claim: 2. Diamond solile disk according to claim 1. Characteristic T part of the sub-claim: characterized in, that the shape of the grooves is such that the forces that occur, in particular the centrifugal forces during high-speed machining neither loosen the cutting inserts, can still endanger the rotational body. The grooves can be dovetail, keyhole, fir tree, te shape or have variations of these forms. The grooves can be straight, curved, kinked or spiral; in your Incorporated in the direction parallel or running at suitable angles to the axis of rotation be. Preamble of the sub-claim: 3. Diamond grinding wheel according to claim 1. Cutting inserts: Characteristic part of the dependent claim, characterized in that these fill the grooves of the rotating body firmly adhering. The cutting inserts are on the working side of the shape of the body of revolution aligned with high accuracy and are on the working side with cutting material coated. The cutting material is primarily diamond grit, but it can also be another Hard material such as boron carbide, boron nitride, ruby. A distinction must be made between pourable or kneadable and hardening Materials in the groove self-made cutting inserts, and the dimensionally prefabricated Ausnusch cutting inserts L e r s e i t e
