Gullco disc knife
Tools designed for rotary cutting are designed for materials with a maximum strength Rm up to 60kg / mm2. If all conditions specified in the instructions for use are observed, the tool life can be up to 4000 meters. In practice, however, we are around 2000-3000 meters. Several factors affect tool life:
Material and its preparation. As already written, it is necessary to observe the maximum strength of the bevelled material. When chamfering materials with a higher than permissible strength, the service life of the tool is rapidly reduced, but mainly there is a risk of tool destruction or damage to the machine.
The preparation of the material before beveling can also have a significant effect on the tool life. If the material in your workplace is cut by burning, we recommend cleaning the edges to be beveled with an angle grinder. During firing, especially during plasma firing, the edges of the material are hardened. This can have a significant effect on the final life of the tool. We recommend proceeding with caution.
Tool care. It is very important to control the sharpness of the tool during chamfering. If you find it blunt, it must be thoroughly sanded. If you neglect this duty and continue working, the tool may break or the machine may be destroyed.
Workflow. The machining process is also important. This is thoroughly described in the instructions for use. In general, when performing the maximum possible bevels, it is necessary to divide the bevel into two chips.
