With the rapid development of the machinery industry and green energy (wind power), gears as transmission components are particularly important. The machining of the gear not only requires it to have a precise geometry, but also requires high speed and high efficiency. Nanjing Lanzhi Metal Processing Technology Co., Ltd. will show you a high-speed, high-efficiency indexable carbide heavy-duty cutting hob at the CIMT Exhibition E2-C114 booth in 2009.
This is a very economical hob that machines gears with a modulus of 5 or more. It can be said that it is a revolution in the rolling cutting technology. The design concept is to combine a cost-effective carbide insert with the well-known hobbing advantages to remove large amounts of metal at high cutting speeds within a specified time.
Re-grinding and recoating are necessary for conventional hobs and are not necessary here. The cost of repairing and the time of tool change are greatly saved, which will reduce the investment of the machine tool, thereby reducing the construction of the factory building and realizing a large cost for the user.
The wear marks on a single tooth vary from process to process. For large gears, they can be partially equivalent by shifting. Thus when using indexable inserts, these inserts are rotated or replaced when the maximum wear mark width is reached. Replacing the indexing blade or blade does not require the hob to be removed from the machine, which saves on-duty time.
In order to successfully use such a hob, the machine tool is required to have sufficient rigidity and required speed and drive power.
Fitt's indexable carbide insert hob structure consists of a hob body on which the upper blade and the indexable carbide insert are screwed and then closed with a closed ring, wherein the blade passes through the compression The screw is fixed in the holder, the cylindrical cutter body has a spiral groove, and the side of the groove is ground according to the guiding of the cutter body, and the ground portion of the milled cylinder is always kept between the two grooves. Supports the blade. The position of the slats is determined by the two cylindrical pins under the guidance of the grooves. The blade is fixed to the body by screws. The holder of the indexed carbide insert is tangentially mounted on the body.
On the blade, the seats are staggered. This purpose is to keep the axial reaction force acting on the body and the tangential force on the gear as small as possible.
Indexable carbide inserts must completely cover tool cutting. The number of indexable inserts and their distribution depends on the size of the insert and the size of the gear. In order to give the optimum reserve for scraping or grinding, the indexable insert carbide carbide hob can be rooted or chamfered on the gear.
By understanding its structural design, you will realize that this indexable carbide hob is the ideal tool for high speed, high efficiency and economy in modern gear processing industry.
