Abstract

Disclosed is a flying saucer milling cutter for processing a deep-cavity groove. A deep-cavity groove with the depth being 3-5 times of the semidiameter of the milling cutter can be processed. The flying saucer milling cutter for processing the deep-cavity groove is characterized in that the special flying saucer milling cutter is composed of a cutter bar (1), blades (2) and fixing screws (3). The blades (2) are arranged at the front end of the cutter bar (1) and are fixed on the cutter bar (1) through the screws (3). In the common application background of the flying saucer milling cutter for processing the deep-cavity groove, the depth of a cut cavity body is generally large and the process is a typical deep-hole processing. When the milling cutter processes a groove from the shallower to the deeper, as the cutting depth increases, axial stress of the milling cutter increases gradually, and vibration of the milling cutter strengthens obviously. When the milling cutter processes the groove from the deeper to the shallower, stress of the milling cutter decreases gradually and vibration weakens gradually, and therefore service life of the milling cutter is prolonged, and the effect is more obvious when the length-diameter ratio is greater than three.

Description

A kind of dark chamber groove processing flying saucer milling cutter

Technical field

The utility model relates to a kind of dark chamber groove processing flying saucer milling cutter.

Background technology

The groove processing of dark chamber has wide range of applications in the machining practice, and is indispensable.Impeller take blade profile as complex free curved surface is example, and the maximum material removal rate of material can reach more than 93%.At present, the processing method of integral wheel adopt more bore mill, hold that R milling cutter layer is cut, displacement inserts to mill and slightly opens grain and process, because cobalt mills, displacement is inserted to mill and belonged to large cutting-in multiaxis constant speed processing, and the free form surface shape is comparatively complicated, this just caused owe to cut the position and owe the amount of cutting inconsistent.In order to reduce finish-milling machining deformation amount, must adopt rose cutter or end R milling cutter point position to mill the method for processing so that the surplus homogenising.

People urgently wish to obtain the good dark chamber groove processing milling cutter of a kind of technique effect.

Summary of the invention

The purpose of this utility model provides the good dark chamber groove processing flying saucer milling cutter of a kind of technique effect.

It is the dark chamber groove of 3-5 times of tool radius that the utility model provides the groove processing of a kind of dark chamber to use flying saucer milling cutter, working depth; It is characterized in that: special-purpose flying saucer milling cutter is made of knife bar 1, blade 2, hold-down screw 3, and blade 2 is positioned at the front end of knife bar 1 and is fixed on the knife bar 1 by hold-down screw 3.

The groove processing of described dark chamber is preferably three with the flying saucer milling cutter, and blade 2 is three, and blade 2 is triangle.

In the application background commonly used of the present utility model, it is generally larger to be cut cavity depth, belongs to typical deep hole machining.When cutter from the superficial to the deep adds man-hour, increase along with cutting depth, the suffered axial force of cutter increases gradually, vibration cutting can obviously be strengthened, and when from the superficial to the deep adding man-hour, cutter is stressed can be reduced gradually, vibration can weaken gradually, this is conducive to cutter life, especially when draw ratio greater than 3 the time, effect can be more obvious.

Description of drawings

Below in conjunction with drawings and the embodiments the utility model is described in further detail:

Fig. 1 is dark chamber groove processing flying saucer milling cutter construction simplified schematic diagram;

Fig. 2 is the simplified schematic diagram that the blade 2 of flying saucer milling cutter is used in the groove processing of dark chamber.

The specific embodiment

Embodiment 1

It is the dark chamber groove of 3-5 times of tool radius that flying saucer milling cutter, working depth are used in the groove processing of a kind of dark chamber; It is made of knife bar 1, blade 2, hold-down screw 3, and blade 2 is positioned at the front end of knife bar 1 and is fixed on the knife bar 1 by hold-down screw 3.The groove processing of described dark chamber is preferably three with the flying saucer milling cutter, and blade 2 is three, and blade 2 is triangle.

In the application background commonly used of present embodiment, it is generally larger to be cut cavity depth, belongs to typical deep hole machining.When cutter from the superficial to the deep adds man-hour, increase along with cutting depth, the suffered axial force of cutter increases gradually, vibration cutting can obviously be strengthened, and when from the superficial to the deep adding man-hour, cutter is stressed can be reduced gradually, vibration can weaken gradually, this is conducive to cutter life, especially when draw ratio greater than 3 the time, effect can be more obvious.

Claims

1. to use flying saucer milling cutter, working depth be the dark chamber groove of 3-5 times of tool radius in a dark chamber groove processing; It is characterized in that: it is made of knife bar (1), blade (2), hold-down screw (3), and blade (2) is positioned at the front end of knife bar (1) and is fixed on the knife bar (1) by hold-down screw (3).

2. use the flying saucer milling cutter according to the processing of the described dark chamber of claim 1 groove, it is characterized in that: groove processing in described dark chamber is three with the flying saucer milling cutter, and blade (2) is three, and blade (2) is triangle.
