Embodiment 1

[0084] Step 1: Prepare materials to generate walls.

[0085] The workpiece 1 is corrected by the sawing machine, so that the shape of the workpiece 1 is larger than the net size of the product by 5 on one side, and the one side constitutes the wall 2 . Next, a top hole 3 is formed on the enclosure wall 2 by means of process pins. A positioning hole 4 on the side of the wall 2 is formed on the side of the wall 2 . In order to facilitate the construction, a vise can be used for auxiliary positioning, and the clamping thickness of the vise is 3mm. Furthermore, considering that workers can know the correct direction of product clamping in time, a reference angle 6 for identifying the product clamping direction is provided on the enclosure wall 2 .

[0086] Step 2, rough machining by the machining center.

[0087] For the rough machining of the front surface, the milling cutter is used, and the corresponding parameters suitable for the machining of the workpiece are called for m...

Embodiment 2

[0094] Step 1: Prepare materials to generate walls.

[0095] The workpiece 1 is corrected by the sawing machine, so that the shape of the workpiece 1 is 10mm larger than the net size of the product on one side, and the one side constitutes the wall 2. Next, a top hole 3 is formed on the enclosure wall 2 by means of process pins. A positioning hole 4 on the side of the wall 2 is formed on the side of the wall 2 . In order to facilitate the construction, a vise can be used for auxiliary positioning, and the clamping thickness of the vise is 5mm. Furthermore, considering that workers can know the correct direction of product clamping in time, a reference angle 6 for identifying the product clamping direction is provided on the enclosure wall 2 .

[0096] Step 2, rough machining by the machining center.

[0097]For the rough machining of the front, use the drill bit, call the corresponding parameters suitable for the workpiece processing, and reserve a margin for the feature of...

Embodiment 3

[0104] Step 1: Prepare materials to generate walls.

[0105] The workpiece 1 is corrected by the sawing machine, so that the shape of the workpiece 1 is 7 mm larger than the net size of the product on one side, and the one side constitutes the wall 2 . Next, a top hole 3 is formed on the enclosure wall 2 by a process pin, and a positioning hole 4 on the enclosure wall 2 side is formed on the side of the enclosure wall 2 . In this way, the workpiece 1 is limited by the combination of the process platen 5 and the side positioning hole 4, so as to prevent the position of the product from moving due to force during processing. A vise with a clamping thickness of 4 mm is used for auxiliary positioning.

[0106] Step 2, rough machining by the machining center.

[0107] Specifically, it mainly includes front rough machining and back rough machining. The boring tool is used for the rough machining of the front surface, and a margin is reserved for the feature of the workpiece 1 on ...

Abstract

The invention relates to a thin-wall thin-bottom product machining method suitable for a numerical control machine tool. The thin-wall thin-bottom product machining method suitable for the numerical control machine tool is characterized in that an enclosure is formed through a prepared material; rough machining is conducted on the enclosure through a machining center; heat treatment is conducted on the rough-machined enclosure; finally, finish machining is conducted through the machining center, and a thin-wall thin-bottom product is obtained. Thus, the machining method can be effectively suitable for machining different types of thin-wall thin-bottom products, and better machining adaptability is achieved. Meanwhile, the machining efficiency is high, and the quality of the products is stable. More importantly, the machining method relies on the machining technology of constructing a structure similar to the enclosure, excess materials of a product itself can be effectively utilized to conduct strength protection on the product when machining is conducted, and the situation that the product is crushed or pressed is avoided, and the finish degree of the finished product is high; the situations that due to the fact that the product is thin in structure, in the machining process, the quality of the product is unstable and the surface quality is poor can be prevented; in addition, the condition that other auxiliary tools are needed for support can be avoided, and waste does not occur in the production preparation process.

Description

technical field [0001] The invention relates to a product processing method, in particular to a thin-wall and thin-bottom product processing method suitable for numerical control machine tools. Background technique [0002] At present, there are basically the following methods for machining thin-walled and thin-bottomed products: [0003] 1. Processing by wire cutting machine tool. [0004] The shape of the product processed by this method is single, the surface finish after processing is poor, and the processing efficiency is low. It is suitable for sample production, and batch and mass production are difficult to achieve. [0005] 2. The machining center is used to cooperate with the wire cutting machine tool for processing. [0006] In the actual operation process, the secondary clamping is easy to produce cumulative processing errors; and the surface finish after wire cutting processing is poor and the processing efficiency is low. This processing technology is suitabl...
