Problems solved by technology

When the press-in force is too large, the end face of the ferrule will be damaged, and if the press-in force is too small, it will cause disengagement and reliability failure
This requires that the hole diameter tolerance of the metal parts is very small, and the cost of achieving this tolerance in CNC machining is relatively high

Embodiment

[0017] Example: such as figure 1 Shown is the workpiece that needs to be processed in the embodiment of the present invention. The workpiece a is a component of an optical interface assembly. During installation, a ceramic ferrule needs to be installed in the inner hole of the workpiece a, such as figure 1 The mounting hole b shown is a hole that needs to be matched with the ceramic ferrule. This invention is an embodiment of the grinding process of the inner hole of the metal component of the optical interface. The specific production steps of the grinding process are:

[0018] (1) Use a drill to perform rough machining on a CNC lathe to process the ferrule assembly holes;

[0019] (2), select the steel wire equivalent to this aperture;

[0020] (3), coated with abrasive paste on the steel wire;

[0021] (4), the steel wire is installed on the motor to rotate;

[0022] (5) Wear the product on the steel wire for inner hole grinding;

[0023] (6) Clean the product.

Abstract

The invention discloses a grinding process of an inner hole of an optical interface metal component. The grinding process comprises the following specific production steps: (1) a drill bit is used for roughly machining out an insertion core assembly hole on a CNC lathe; (2) a steel wire having an equivalent aperture to the insertion core assembly hole is selected; (3) grinding paste is coated on the steel wire; (4) the steel wire is mounted on a motor to rotate; (5) a product is inserted on the steel wire to grind an inner hole; and (6) the product is cleaned. The grinding process not only can machine out the inner hole with high precision, but also can improve the production efficiency and reduce the production cost.

Description

Technical field: [0001] The invention relates to the technical field of processing inner holes of optical interface metal components, and more particularly relates to a grinding process for inner holes of optical interface metal components. Background technique: [0002] The ceramic ferrule and the pressure block are assembled together through interference fit, the outer diameter of the ferrule is larger than the hole diameter of the metal part, and the ceramic ferrule is assembled in the metal base by pressure. When the press-in force is too large, the end face of the ferrule will be damaged, and if the press-in force is too small, it will cause disengagement and reliability failure. This requires that the hole diameter tolerance of the metal parts is very small, and the cost of achieving this tolerance during CNC machining is relatively high. Invention content: [0003] The object of the present invention is to provide a grinding process for the inner hole of the optica...
