Problems solved by technology

[0003] The cutting discs known so far have the disadvantage that, due to the unavoidable more or less eccentricity of the cutting disc circumference relative to the rotational axis of the portable grinding machine tool, only a small area of ​​the cutting disc circumference is available at the start of the grinding or cutting process. acting on the material to be processed
The area of ​​the cutting disc that acts first will be overloaded under hard loads, thereby vitrifying some of the cutting segments of the circumference and reducing its cutting function; Open the cutting disc and make it unusable
In addition, the cutting disc causes disturbing vibrations due to its uneven action into the workpiece

Embodiment Construction

[0019] exist figure 1 The portable grinding tool shown in side view in FIG. 1 is designed as an angle grinder 10 . This grinding machine (Winkelschleifer) has an elongated machine housing 12, is provided with a handle not shown in detail at its rear end, stretches out a connecting cable 13 from the free end of this handle, is used for not shown out of the motor power supply.

[0020] In the area of ​​the handle, a switch key (not shown in detail) is conveniently provided for switching on and off the electric motor (not shown). At the front end of the housing 12 , the housing has a working spindle 14 extending perpendicularly to the longitudinal direction of the machine housing 12 and serving to rotate a cutting disc 20 clamped in a non-rotatable manner. The cutting disk 20 is inserted on the working spindle 14 with its central hole 24 in such a way that the working spindle passes through the cutting disk 20 so that a clamping nut 18 can be screwed into its thread 15 at the f...

Abstract

A cutoff disc, having an outer periphery provided with particles which are released during wear, a central opening for passage and clamping on a work spindle for the rotary driving on a grinding hand power tool, and an outer ring region which is provided on an outer edge, the outer ring region extending radially outwardly with a tip and forming a small cutting edge.

Description

technical field [0001] The invention relates to a cutting disc for a portable power tool. Background technique [0002] A variety of cutting discs for grinding are known, for example from DE 102 08 818 C1, which can be clamped on the spindle of a portable grinding machine with a central hole and can be used for all types of workpieces, especially for cutting, and in special cases also for smoothing brazed or welded seams of metal workpieces or removing irregularities on cementitious parts. [0003] The cutting discs known so far have the disadvantage that, due to the unavoidable more or less eccentricity of the cutting disc circumference relative to the rotational axis of the portable grinding machine tool, only a small area of ​​the cutting disc circumference is available at the start of the grinding or cutting process. acting on the material to be processed. The area of ​​the cutting disc that acts first will be overloaded under hard loads, thereby vitrifying some of the...
