The macro for cable reel groove carries out the roughing and finishing of a circular groove, developed helically in the direction of the Z axis; it is similar to a thread but with a circular profile. It can be used for machining groove on cable reels, radial groove for conveying cooling fluid or for all applications where a radial profile with a constant pitch must be machined.

The same macro can be used both when machining is carried out in the negative Z direction and in the positive Z direction. This is the case when cable reeling pulleys with right and left helixes are to be executed on the same pulley. The entry must always take place in an unloaded zone or outside the piece. The exit can also take place in the solid, since the macro automatically calculates a smooth exit from the piece always following the angle of the helix; by means of a parameter it will be possible to choose the type of exit from the piece.

In roughing, the cuts calculation for the opening of the cable reel groove is calculated automatically on the basis of the tool load percentage; the CNC macro will automatically calculate the number of cuts required to rough the profile for each diameter coordinate. In finishing, it will be possible to set the maximum height of the ridge that determines the roughness of the profile. It will automatically calculate the cuts both on the radius of the connection with the external diameter and on the whole radiused profile.

The macro is compatible with the Fagor 8065 control in both ISO and self-learning modes and requires the intervention of our technicians to install the conversational templates. The operator will use the cycle exactly as he uses all the other Fagor turning cycles, by filling in the fields in the conversational template.
