Problems solved by technology

Such a process has a great influence on the chip flute. The processing depth of the spiral chip flute is not deep. Because of the constraints of the intermediate cooling hole, the center of the tool and the core must be thickened. In order to ensure that the tool has sufficient rigidity, the row The thickness of the center core of the chip flute must be increased, so that the chip flute is not deep

Embodiment 1

[0024] The utility model relates to a cutting tool, which is a cemented carbide indexable shallow hole drill, which is a hole processing tool and is mainly used for drilling solid materials. Applicable to CNC machine tools, machining centers, ordinary lathes, boring machines, drilling machines and other equipment, the processing method includes the following steps;

[0025] A. According to the drawings, use a lathe to process the shape of the tool, such as a Φ30mm tool, the main body diameter is Φ29mm

[0026] B. Process the cooling hole 3, process two symmetrical through holes on the tool, the diameter of the two through holes is Φ2mm, and the distance between the axis center of the hole diameter and the axis center 5 of the tool body is 9mm.

[0027] C. Machining straight flutes, two straight flutes are milled out by a milling machine on the outer circumference of the tool, the length of the flutes is 95mm, the width is 10mm, and the depth is 4.5mm.

[0028] D. The cooling ...

Abstract

The invention discloses a cutter processing process, which comprises the following steps that A, the appearance of a cutter is processed by a lathe according to a drawing; B, cooling holes are processed, and two symmetrical through holes are processed in the cutter; C, straight chip discharging grooves are processed, and two straight chip discharging grooves are processed on the outer circumference of the cutter; D, high-temperature-resistant materials are fully filled in the cooling holes; E, high-frequency heating is carried out, the products are fixedly arranged on a clamp, a layer of high-frequency coil is arranged on the outer circle of the products, and the heating temperature is 300 to 450 DEG C; F, the straight chip discharging grooves are twisted into spiral grooves. The cutter processing process has the advantages that through the processing method, the processing difficulty is reduced, meanwhile, the step of forming a cooling groove in the center of the cutter is omitted, the rigid of the cutter is guaranteed, meanwhile, the depth of the chip discharging grooves is also increased, the depth of the chip discharging grooves twisted by a hot twisting process is greater than the depth of the chip discharging grooves processed by a traditional method, the chip accommodating space is greater, iron chips can be conveniently discharged out, the smoothness of inner holes and the precision of the hole diameter dimension can be perfectly guaranteed.

Description

technical field [0001] The invention relates to a processing technology, in particular to a tool processing technology of a drilling tool. Background technique [0002] At present, the traditional flute processing is to use a milling machine or a special machine tool to process it into a spiral flute. The tool needs to be cooled during processing, and a cooling hole needs to be set on the tool. At present, the center cooling hole processing technology of the tool center is to drill a hole with a diameter of 4.3-4.5mm in the middle of the tool, and then drill two holes on the head of the tool. The small cooling hole communicates with the main cooling hole. Such a process has a great influence on the chip flute. The processing depth of the spiral chip flute is not deep. Because of the constraints of the intermediate cooling hole, the center of the tool and the core must be thickened. In order to ensure that the tool has sufficient rigidity, the row The core thickness of the ...
