Taillage d'engrenage rapide

Bonjour à tous

J'enfonce peut-être une porte ouverte, mais je viens de decouvrir un truc que je ne connaissais pas.

J'ai appris à tailler les engrenages à l'école avec des fraises-module en acier et un diviseur ou avec des fraises-meres carbure et une machine à tailler.

Mais je viens seulement de decouvrir qu'il existe aussi des fraises-module à plaquette carbure jetable.

J'y vois trois avantages : plus rapide que les fraises acier, possibilité d'usiner des aciers préraités et investissement sans commune mesure avec une tailleuse et sa collection de fraises-meres.

Bonjour,
et merci moi non plus je ne connaissais pas, en fait c'est un peu "le fly cutter pour les gens d'en haut".
Cordialement

Merci,
je ne connaissais pas
si j'ai bien compris il faut une plaquette différente selon la catégorie de nombre de dents pour conserver le bon profil ?

Ils n'en parlent pas, mais ça doit etre comme pour les fraises module : le profil change suivant le nombre de dents de la roue a tailler.

ISCAR introduces new solutions for gear milling based on solid carbide milling heads and cutters carrying tangentially clamped inserts.


1. T-GEAR Milling Solid Carbide Heads with T-SLOT Spline Connection
ISCAR is expanding the application options of T-SLOT slot milling cutters with replaceable solid carbide heads by adding new T-GEAR heads that have been designed for gear milling.

The new heads are designated as SD D32-M…-SP15, and have been designed for milling involute gears that meet the requirements of standard DIN 3972, with a basic profile II for finishing and a module range of 1.00 - 2.00 mm.

The new heads feature a nominal diameter of 32 mm with 8 teeth to be mounted on standard T-SLOT SD shanks with SP15 spline connection size.

The new heads enable efficient high-performance involute side milling, increasing the versatility of the T-SLOT tool family.

MODUGEAR Tool for Gear Milling Applications
Iscar introduces another solution for gear milling applications, providing a tool with tangentially clamped indexable inserts.

The new ETS D63-M1-1.75-W25-C disk type tool features a Weldon shank and coolant channels directed to each of the cutting edges. It carries 10 tangentially clamped inserts that can be used for a 1.00 to 1.75 mm gear module range.

The LNET 18-M1.50-NO3-C IC908 insert has been designed for milling involute gear teeth according to standard DIN 3972 basic profile II, with 1.5 mm module and 17-20 tooth range.

Note: Other cutter diameters with alternative connection options (shank or arbor-types) or insert profiles within the mentioned module range can be provided on request.
