A Combined Cutting Tool for Stainless Steel Deep Grooving

Abstract

The invention discloses a combined cutting tool for processing stainless steel deep grooves, which mainly consists of a handle and a cutting head. The cutter head is equipped with 4 blades, of which two HFPR3003 blades for deep grooves are installed at the front end of the cutter head, and the other two VCMT110304 blades for chamfering are installed in the middle of the cutter head. The cutter head is cylindrical and has 16 blades. The outer edge of a knife is used for machining the major diameter of the groove, and the inner edge of the blade 17 is used for the minor diameter of the machining groove. There is a buffer groove on the cutter head, and the chip removal groove is "Y" shape. The front part of the chip removal groove simulates the shape of chip removal, which is an R curve. For the service life, water outlet holes are designed on the top of the four blades, so that the coolant can be accurately sprayed to the tip of the blade to achieve timely cooling effect. The knife rod is integrally formed by spring steel bar stock, without welding in the middle, and its overall rigidity is good, which solves the problem of deep groove processing on the end face.

Description

technical field [0001] The invention relates to a tool for processing end face grooves, in particular to a combined tool suitable for batch processing of deep grooves on the end face of stainless steel workpieces. Background technique [0002] As we all know, the difficulties in processing stainless steel materials are: 1. High cutting force and high cutting temperature; 2. Serious work hardening; 3. Easy to stick to the knife; 4. The tool wears quickly. In view of the above difficulties, frequent tool changes during the machining process affect production efficiency and increase the cost of tool use. In particular, the processing of stainless steel deep grooves has become a difficult problem in the industry. In the field of grooving, it is recognized that the "Iscar" tool is the most useful tool, especially the grooving tool for processing stainless steel. Use "Iscar" knives for comparison.

AI Technical Summary

Problems solved by technology

If the workpiece is produced in a single piece or in small batches, you can consider sharpening or welding the blade. However, this product is a batch order. If you grind the tool yourself or use a welded tool, the dimensional accuracy and tool life of the tool cannot meet the requirements. , the processing accuracy cannot be guaranteed, and the processing efficiency will be reduced accordingly, so sharpening or welding knives cannot meet the requirements of mass production.
