Description

Technical Field

[0001] The utility model relates to precision machining equipment and the cutting tools used thereby, and particularly to an end face grooving tool. Background Art

[0002] For end face grooving, grooving tools are generally used. However, in some cases, the specifications of the end face grooves are small while the depth is large, resulting in that during machining, the external coolant cannot enter, affecting the machining quality of the end face grooves and the service life of the grooving tool at the same time.

[0003] Therefore, it is necessary to provide an end face grooving tool to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an end face grooving tool.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] An end face grooving tool comprises a tool shank, and an end face grooving tool body is connected to the tool shank;

[0007] A coolant flow-through groove is arranged on the tool shank, and a drainage groove body is arranged on the connecting body of the corresponding end face grooving tool body; the coolant flows in through the coolant flow-through groove, and part of it directly flushes and lubricates the end face grooving tool body to form a direct flushing tool body cooling structure, and the other part flows to the machined end face groove through the drainage groove body to form a machined body drainage cooling structure. The direct flushing tool body cooling structure and the machined body drainage cooling structure are combined to form a high-efficiency cooling type end face grooving tool setting structure.

[0008] Furthermore, the number of the coolant flow-through grooves is two, which are symmetrically arranged on both sides of the tool shank.

[0009] Furthermore, the width of the coolant flow-through groove is 1 / 2 - 2 / 3 of the diameter of the tool shank.

[0010] Furthermore, the depth of the coolant flow-through groove is 10% - 15% of the diameter of the tool shank.

[0011] Furthermore, the upper circle of the end face grooving tool body is flush with the outer diameter of the tool shank.

[0012] Furthermore, the height of the connecting body of the end face grooving tool body is 35% - 45% of the diameter of the tool shank.

[0013] Furthermore, the drainage groove body is an arc-shaped downward groove body.

[0014] Compared with the prior art, the utility model has a combination of a direct flushing tool body cooling structure and a machined body drainage cooling structure, forming a high-efficiency cooling type end face grooving tool machining method, ensuring the machining accuracy of products and effectively guaranteeing the service life of the cutting tool at the same time.
