Abstract
The utility model relates to a turnable screw end mill. The original turnable screw end mill which is integral is not provided with a replaceable head, when a head part is damaged, the whole mill can not be used, the service life of a cutter is influenced and cost is enhanced. The turnable screw end mill comprises a mill body 5, wherein the front end of the mill body 5 is provided with the replaceable head 2, the replaceable head 2 and the mill body 5 are connected by a cylindrical pin 1, blades 3 in arrangement according to a helical track are arranged on the replaceable head 2 and the mill body 5 and the blades are fastened on the mill body through screws 4. The product is suitable for milling step surfaces with small milling amounts of vertical surfaces and front end surfaces, and step surfaces with larger end milling amounts.
Description
Technical field:
The utility model relates to a kind of indexable helical end mill.
Background technology:
Original indexable helical end mill is an one, and interchangeable head is not set, and when head damaged, whole milling cutter just can not be used, and influenced the service life of cutter, had caused the cost raising.
Summary of the invention:
The purpose of this utility model provides a kind of indexable helical end mill that can change cutter head fast.
Above-mentioned purpose realizes by following technical scheme:
Indexable helical end mill, its composition comprises: cutter hub, described cutter hub front end is equipped with interchangeable head, be connected with straight pin between described interchangeable head and the described cutter hub, have the blade of arranging by spiral trajectory on described interchangeable head and the described cutter hub, described blade used screw to be fastened on the described cutter hub.
Above-mentioned indexable helical end mill, described insert tangential is installed on the spiral of 20 ° of lift angles.
This technical scheme has following beneficial effect:
1. be connected with one group of straight pin between interchangeable head and the cutter hub, the helical end mills head is interchangeable, when head damages, can change fast, thereby reduce cost the service life of having improved cutter.
2. blade of the present utility model adopts tangential the installation, and cutting force direction carbide alloy cross section is big, and compressive resistance intensity height can carry out big cutting-in, big feed milling.Cutting force clamps, and only fixes with a screw, and is simple and reliable for structure.
3. the utility model is applicable to that the big cutting-in of carrying out on the multiple lathe, big feed rough mill facade and step surface, and this product has not only satisfied the market demand of high rotating speed, roughing feed, big cutting-in high-speed cutting, and has greatly improved the working (machining) efficiency of lathe.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is vertical views of accompanying drawing 1.
The specific embodiment:
Embodiment 1:
Indexable helical end mill, its composition comprises: cutter hub 5, described cutter hub 5 front ends are equipped with interchangeable 2, described interchangeable 2 with described cutter hub 5 between be connected with straight pin 1, described interchangeable 2 with described cutter hub 5 on have the blade 3 of arranging by spiral trajectory, and it is fastening with screw 4.
Embodiment 2:
Above-mentioned indexable helical end mill, described blade 3 are on the spiral that tangential direction is installed in 20 ° of lift angles.
Claims (2)
1. indexable helical end mill, its composition comprises: cutter hub, it is characterized in that: described cutter hub front end is equipped with interchangeable head, be connected with straight pin between described interchangeable head and the described cutter hub, have the blade of arranging by spiral trajectory on described interchangeable head and the described cutter hub, described blade used screw to be fastened on the described cutter hub.
