Embodiment

[0025] see Figure 1 to Figure 4 , in the present embodiment, the processing method of AF1410 steel parts before quenching comprises the following steps:

[0026] Step 1, manufacture the tooling of milling parts, such as image 3 shown. A plurality of process lugs 1 and tooling 9 are connected by bolts 10 to position the pressing parts, such as Figure 4 shown. In an optional embodiment, if the part has a double-sided structure, two sets of tooling need to be designed for two-sided processing.

[0027] Step 2. Using a five-axis machine tool with a high-pressure cooling system, place the parts and tooling 9 in step 1) on the machine tool. Machine tools with a high-pressure cooling system ensure sufficient coolant during milling and effectively reduce the temperature in the cutting area.

[0028] Step 3. Use the indexable milling cutter 8 to remove the part allowance evenly at equal intervals from top to bottom in the shallow cutting-fast feed cutting method. Specifically, ...

Abstract

The invention belongs to the technical field of machining and specifically relates to a method for machining an AF1410 steel part before quenching. According to the method, high-quality and high-efficiency machining is carried out on the AF1410 steel part before quenching strengthening through a shallow cutting-quick feeding equal-height layer reduction cutting process; when a deep cavity structure exists in the part, a ring cutting and axial layered rough milling-finish milling machining method is adopted so as to solve the problems of vibration of a cutting tool and chatter marks on the surface of the part. Through the method for machining the AF1410 steel part before quenching, the machining efficiency is improved by 3-4 times, the cutting temperature is effectively reduced, the servicelife of the cutting tool is prolonged, the quality of the part is improved, the problems that excess cutting temperature, serious work hardening, poor part quality and the like are solved, and high-quality and high-efficiency machining of the AF1410 steel part is realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method of AF1410 steel parts before quenching. Background technique [0002] AF1410 steel is a new type of low-carbon high-alloy secondary hardening ultra-high-strength new material, which is widely used in the main load-bearing structural parts of aviation. Compared with other commonly used high-strength steels, the yield strength and tensile strength are above 1500MPa and 1600MPa respectively, but the thermal conductivity is only 1 / 3-1 / 4 of other high-strength steels, which is a typical difficult-to-machine material. If the milling method of other commonly used high-strength steels is continued, the cutting temperature will be too high during the machining process, the work hardening will be severe, and built-up edge and phosphorus spines will easily form, which will affect the machining efficiency and part quality. In order to solve this...
