Abstract

The invention relates to a manufacture method of hard disc production line HALO. Firstly, square boards are prepared, appearance and auxiliary holes are milled on a milling machine, the boundary dimension is machined to be 158mm*220mm*6.6mm, and meanwhile, the six auxiliary holes of phi 11mm are machined for clamping; the thickness is machined to be 6.6mm, finish machining is carried out on an arbitrary large plane, the surface smoothness of the large plane can reach 1.6mu , the planeness of the large plane is within 0.05mm, and the large plane is used as a locating reference plane of the next process; the front boundary dimension is machined by a computer numerical control (CNC) machine tool, the thickness is 6.35mm, holes of phi 0.215 inch and phi 0.125 inch are machined to numbers; the reverse side arc angle of R0.02is machined, and characters are carved to numbers; then grooves of two side faces are machined; top face holes are machined; and grooves of a bottom face are machined. By adopting a scientific process method, deformation is reduced, machining is adjusted, planeness requirements are met, machining deformation problems are solved effectively, and production efficiency is improved.

Description

The manufacture method of hard disc production line HALO

Technical field

The present invention relates to the manufacture method of a kind of hard disc production line HALO, belong to the precision processing technology field.

Background technology

HALO is one of core part of hard disc production line, must guarantee flatness after machining more than 0.05mm, and this part is that disc produces the accessory that the line length phase uses, and must enhance productivity, to satisfy client's demand.

Need develop brand-new production technology to guarantee above requirement.

Summary of the invention

The objective of the invention is to overcome the deficiency that prior art exists, the manufacture method of a kind of hard disc production line HALO is provided.

Purpose of the present invention is achieved through the following technical solutions:

The manufacture method of hard disc production line HALO comprises the following steps:

1) prepare a square plate, milling profile and fabrication hole on milling machine, processing appearance and size is processed the fabrication hole that is used for clamping of 6 Φ 11mm simultaneously to 158mm * 220mm * 6.6mm; Thickness is machined to 6.6 mm, and fine finishining any one large plane, and the surface smoothness on large plane reaches 1.6 μ m and flatness in 0.05mm, subsequent processing with large plane as positioning reference plane;

2) adopt CNC lathe first: process positive appearance and size, thickness 6.35mm, hole φ 0.215inch and φ 0.125inch are worked into number;

3) adopt CNC lathe second: processing reverse side arc chord angle R0.02, the number of carving characters;

4) employing CNC lathe the 3rd road: the groove of processing two sides;

5) adopt CNC lathe the 5th road: processing end face hole;

6) employing CNC lathe the 6th road: process the bottom surface groove.

Further, the manufacture method of above-mentioned hard disc production line HALO, step 4), processing two sides groove 0.175.

The substantive distinguishing features that technical solution of the present invention is outstanding and significant progressive being mainly reflected in:

The present invention adopts the process of science to reduce distortion, and machining is adjusted, and the quick-clamping product is to guarantee to reach the flatness requirement; Efficiently solve the machining deformation problem, improved production efficiency, guaranteed normally carrying out of production.Be adapted to the production of existing market similar products.

The specific embodiment

The concrete technology of processing hard disk disc production line HALO is:

1) as Fig. 1, prepare a square plate, milling profile and fabrication hole on milling machine, processing appearance and size is processed the fabrication hole that is used for clamping of 6 Φ 11mm simultaneously to 158mm * 220mm * 6.6mm; Thickness is machined to 6.6 mm, and fine finishining any one large plane, and the surface smoothness on large plane reaches 1.6 μ m and flatness in 0.05mm, subsequent processing with large plane as positioning reference plane;

2) as Fig. 2, adopt CNC lathe first: positive (the anepigraphic side) appearance and size of processing, thickness 6.35mm, hole φ 0.215inch and φ 0.125inch are worked into number;

3) as Fig. 3, adopt CNC lathe second: processing reverse side arc chord angle R0.02, the number of carving characters;

4) as Fig. 4, Fig. 5, adopt CNC lathe the 3rd road: the groove 0.175 of processing two sides;

5) as Fig. 6, Fig. 7, adopt CNC lathe the 5th road: processing end face hole;

6) as Fig. 8, Fig. 9, adopt CNC lathe the 6th road: processing bottom surface groove.

What need to understand is: the above is only the preferred embodiment of the present invention; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
