Below are two diagrams that represent the relationship between broach dimensions (horizontal axis) and broaching head models (vertical axis), both for HEXAGONAL / SQUARE broaches (pic. 1), and for TORX / TORX PLUS broaches (pic. 2).
What are the criteria for choosing the right broaching head?
The choice of the broaching head is carried out through a process that involves taking into account the type of machining, the type of material to be machined, the amount of material to be removed and the type of machine on which the work has to be performed. Let's...
How can I intervene when the machine, during processing, gets locked or other similar problems occur?
Here are some suggestions for solving problems occurred during machining:
During the machining, what thrust pressure is applied between the broaches and the bar of material being machined?
Estimation of the pressure that develops during broaching, according to the type of material to be broached, adopting the following process parameters: No. of revolutions S 900, feed 0.06. The table below shows the estimation of the pressure that develops during...
What are the machining parameters to follow according to the type of steel in the broach, the profile to be made and the type of material to be broached?
Depending on the type of broach (hexagonal, square, torx or torx-plus), its size, the material with which they are made and the metal to be machined, the feeding speeds vary according to the tables below. When choosing the feeding rate and number of revolutions, the...
How to behave in case of square holes machining?
When machining square holes, it is advisable to remember that the amount of material to be removed is almost twice as high as in a hexagonal hole, therefore the thrust to be applied is greater. These types of machining normally require very rigid and high-power...
How long does a broach last? What does the wear of the broaches depend on?
The duration of Brighetti tools depends on the conditions of use, more or less correct, on the characteristics of the material to be machined and on the amount of material removed according to the section to be made. Tips to ensure a longer life of the broach 1) Use a...
What type of coating to adopt according to the type of material to be broached?
Depending on the type of material to be machined, coatings can be applied to the broaches to improve their durability in terms of number of work-pieces produced, such as HDP RED (STAR 4), WONDER, INOX PLUS and TIN. Here are some examples of materials to be machined...
Quali misure di brocce posso montare sui vari brocciatori?
Di seguito riportiamo due schemi che rappresentano la relazione tra le dimensioni di brocce (asse orizzontale) e i modelli di brocciatori (asse verticale), sia per brocce ESAGONALI / QUADRE (fig.1), che per brocce TORX / TORX-PLUS (fig.2).
What are the overall longitudinal dimensions of broaching head with broach mounted?
The overall dimensions of the broaching head + broach vary according to the type of broaching head and they can be:
