Abstract
The utility model relates to a step milling cutter. The step milling cutter is characterized in that the step milling cutter is an integrally formed structure and comprises a cylindrical hilt (1). A milling cutter arbor is connected to the front end of the hilt, is step-shaped and includes a primary cutter arbor (2) and a secondary cutter arbor (3), the primary cutter arbor (2) is arranged at the front end of the hilt, the diameter of the primary cutter arbor (2) is smaller than that of the secondary cutter arbor (3) connected to the rear of the primary cutter arbor (1), the primary cutter arbor and the secondary cutter arbor are coaxial with the hilt and provided with two cutting edges, a chamfering edge is arranged at a connection position of the primary cutter arbor and the secondary cutter arbor, and an included angle between the chamfering edge and the axis of each of the primary cutter arbor and the second cutter arbor is 45 degrees. When used for machining a chamfered step groove, the step milling cutter can realize one-step forming and is high in machining precision, and production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of milling cutter, particularly a kind of slotting cutter.
Background technology
In the prior art, when processing had the step groove of chamfering, conventional method processed the one-level groove for using the less milling cutter of diameter earlier, re-uses the bigger milling cutter of diameter and processes the secondary groove; Change rose reamer at last and process the chamfering between the two stage channel, so, processing a step groove just needs to use three cutter; Efficient is very low, and, when changing cutter; Need tool setting again, certainly will produce error in the tool setting process, cause machining accuracy lower.
The utility model content
In order to overcome above-mentioned technological deficiency, the purpose of the utility model is, provides a kind of one-stop operation just can process the milling cutter of the step groove with chamfering.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of step milling cutter, the structure that is formed in one comprises a cylindrical knife shank, said handle of a knife front end is connected with milling arbor; Said milling arbor is step-like, has two-stage, wherein; The one-level knife bar is arranged at the knife bar front end, and its diameter is less than its latter linked secondary knife bar, said two-stage knife bar and the coaxial setting of handle of a knife; The two-stage knife bar all has two cutting edges, and wherein, I and II knife bar junction is provided with and becomes 45 ° chamfering blades with its axis.
The beneficial effect of the utility model is, uses the step milling cutter of the utility model to process the step groove with chamfering, but one-shot forming, machining accuracy is high, and production efficiency improves greatly.
Description of drawings
Fig. 1 is the structure chart of the utility model step milling cutter.
The specific embodiment
As shown in Figure 1:
The step milling cutter of present embodiment, the structure that is formed in one comprises a cylindrical knife shank 1, said handle of a knife front end is connected with milling arbor; Said milling arbor is step-like, has two-stage, wherein; One-level knife bar 2 is arranged at the knife bar front end, and its diameter is less than its latter linked secondary knife bar 3, said two-stage knife bar and handle of a knife 1 coaxial setting; The two-stage knife bar all has two cutting edges, and wherein, I and II knife bar junction is provided with and becomes 45 ° chamfering blades 4 with its axis.Use the step milling cutter of the utility model to process step groove with chamfering, but one-shot forming, machining accuracy is high, and production efficiency improves greatly.
