Embodiment Construction

[0011] The specific structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] See attached figure 1 As shown, a deep and shallow groove milling cutter includes a cutting part 1 and a handle 2. The cutting part 1 is provided with four helical cutting edges 3, and the part between two adjacent cutting edges 3 forms a row The chip flute 4, the front end face of the front part 11 of the cutting part 1 forms a face cutting edge.

[0013] as attached figure 2 As shown, the core thickness of the front part 11 is about 1 / 2 of the diameter of the cutting part 1, that is, the groove depth of the flute 4 at the front part 11 is 1 / 4 of the diameter of the cutting part; as attached image 3 As shown, the core thickness of the rear part 12 is about 3 / 4 of the diameter of the cutting part 1, that is to say, the groove depth of the flute 4 at the rear part 12 is 1 / 4 of the diameter of the cutting part 8. The length ratio o...

Abstract

The invention relates to a deep and shallow groove milling cutter, which comprises a cutting part and a cutter handle, wherein the cutting part is provided with at least two spiral cutting blades and is divided into a front part and a rear part from front to back along a length direction; an end face cutting blade is formed on the front end face of the front part; the core thickness of the front part is 1 / 2 of the diameter of the cutting part, while the core thickness of the rear part is 3 / 4 of the diameter of the cutting part; and the length ratio of the front part to the rear part is 1:2-4. When a work piece is machined, the milling cutter is favorable for timely discharging scrap iron in cutting without influencing the rigidity of the whole cutting part so as to avoid the occurrence of flapping and cutter relieving conditions in machining and improve work piece machining accuracy.

Description

technical field [0001] The present invention relates to an end mill. Background technique [0002] In the prior art, when an end mill is used for deep hole machining, or when the feed length is relatively deep, the length of the tool is generally longer, so the rigidity of the tool is usually poor; by increasing the diameter of the tool and reducing the chip flute The depth of the flute can improve the problem of poor rigidity of the tool. However, if the chip flute of the milling cutter is shallow, the chip cannot be removed normally during cutting, which is not conducive to the processing of the workpiece; if the flute of the milling cutter is deep, the cutting It often happens that the tool vibrates and lets the tool go, resulting in the processed workpiece not meeting the requirements. Therefore, it is necessary to find a tool that can improve the problem of poor rigidity of the tool and quickly discharge cutting chips. Contents of the invention [0003] The object o...
