A perfect result with the right cutting edge for the cutter



Many times it can happen that you have performed a machining but the result is far from satisfactory and at the end of the machining, after having designed the perfect milling for days, this is what should not have happened, that is, a decidedly inaccurate finish.


At this point it may not be clear why the finish is so unsatisfactory and it is not considered that it was enough just to choose the most appropriate cutter for the machining to be performed. It therefore happens to complain about not having purchased a good quality cutter, when instead, the problem may be suitability for the intervention. For Wooden Work in Dubai Visit us.


Often a customer asks his buyer, mistakenly, what is the quality of the product he is buying, asking the wrong question, because the most suitable one would be useful to know the right cutter for the machining to be performed.


Therefore, a milling can go wrong especially because the cutter used is not suitable for the process in question and each activity requires its own cutter, its tool or the most suitable tool.

Choose the right type of cutting edge for the cutter


It is not enough to ask the dealer for an 8 cutter, because there would be four different types, for equally different processes, at which point it is up to the buyer to decide whether to obtain the best result or reduce the amount of cutters available.


To avoid these errors it is important to know each use of the cutter and its composition, the type of cutting edge it mounts, and so on.


So, once you have understood what the machining to perform is and once you have identified the characteristics of the material on which you are working, you can finally choose the type of cutting edge, which will be the one that best suits the machining and will produce a final result. really satisfying.




The cutting edges to be used can be of four types and are distinguished as follows:


  • with “standard” STRAIGHT plate;

  • with POSITIVE helix;

  • with NEGATIVE helix;

  • with DOUBLE propeller, POSITIVE AND NEGATIVE.

 


What distinguishes the different types of cutting edges for the cutter

The aforementioned types of cutting edge are detailed below.


 


"Standard" STRAIGHT plate cutting edge


This type of cutting edge is also referred to as the “Standard cutting edge” and is the most used in brazed cutters. The brazed-welded cutter is the classic one, consisting of a steel body and plate, welded in widia, for example the Fraser 102.020.6D.


 


This product promises to be the right compromise for good workmanship, which can be applied to most surfaces.


 


POSITIVE HELIX cutting edge


This type of cutting edge belongs to the type of integral helical carbide milling cutter, it means that it is made entirely of widia and is characterized by the positive helix on the right, which determines how the rotation of the positive helix cuts the chip, which is discarded, and extrudes upward. In this milling, the wood, subjected to processing, has a perfect surface in the lower part.


 

NEGATIVE HELIX cutting edge


This type of cutting edge belongs to the type of integral helical hm cutter, which in a different way than the positive one, has a cutting edge with a negative helix, this means that the rotation of the negative helix cuts the chip, which is discarded, and extrudes it. downward. In this way the wood that undergoes the milling looks perfect in the upper surface part.


 


DOUBLE HELIX cutting edge - POSITIVE AND NEGATIVE


This type of cutting edge belongs to the type of integral widia cutter, it means that it has the body entirely in widia and has a double helix, it means that it has a double cutting part, both positive and negative, for this reason it is possible to obtain a perfect finish both in the upper part and in the lower part of the surface, in this case the waste is extruded both upwards and downwards. This cutter is optimal for obtaining perfect results.
