80 + (19.3 x 2 x 1.414) =134.58 so approximately 134.6 mm
3.6.4 Quantity of cutting bits
To obtain a good quality of the machining, the PERTICI SPA company suggests the use of
milling cutters with at least 8 (eight teeth) cutting bits.
3.6.5 Max. diameter of milling cutters
The CM4/S permits to install milling cutters with a max. diameter of 260 mm
3.6.6 Min. diameter of milling cutters
The CM4/S permits to install milling cutters with a min. diameter of 70 mm.
3.6.7 Connecting hole of milling cutter pack
The diameter of the milling cutter holding shaft of the CM4/S is Ø 32 h6 (tolerance 0 / -0.016).
The optimum coupling happens when the connecting hole of the milling cutter has a diameter of
Ø 32 G7 (tol0.009 /+0.034).
3.6.8 Balancing of milling cutter packs
Before using a milling cutter pack, it is very important to check its balancing.
The milling cutter pack at the rotating speed of 3000 rounds per minute must not operate a
transversal force greater than 1 gram-force.
ATTENTION: THE USE OF NOT BALANCED MILLING CUTTER PACKS INVOLVES
DAMAGES TO THE BEARINGS OF THE MOTOR SUPPORTING THE MILLING CUTTER
HOLDING SHAFT.
3.6.9 Knifes for welding seal removal
The CM4/S is equipped with two knifes to remove the upper and lower welding seal.
The machine permits the machining of almost all types of commercial profiles.
The standard kit of the machine consists in knifes producing a 3-mm width and 0.5 mm depth
trace.
