Problems solved by technology

At present, most high-precision diamond tools and micro-tools are manufactured by mechanical grinding. For the processing method of high-precision diamond indenters, foreign diamond tool manufacturers regard it as a commercial secret, and there are few reports on the materials and literature related to related processes. In China, there are only relevant studies on the design and processing of pyramidal indenters.

specific Embodiment approach 1

[0031] Specific implementation mode one: as Figure 1 to Figure 7 As shown, the invention discloses a mechanical grinding process of a high-precision single crystal diamond conical indenter, comprising the following steps:

[0032] Step 1: Preparation of single crystal diamond crystal blank, select regular octahedral natural diamond material, determine the axis direction of the indenter, use a laser cutting machine to cut the single crystal diamond crystal blank along the direction perpendicular to the axis of the indenter, and then figure 1 The cutting surface of the single crystal diamond crystal blank is ground to a single crystal diamond crystal by using 800# bronze diamond grinding wheel disc on the diamond tool grinding machine shown;

[0033]Step 2: Welding of single crystal diamond indenter, choose low thermal expansion coefficient (≤1.5×10 -6 / K) Invar material is used as the indenter shank, and the single crystal diamond crystal is welded on the end of the indenter ...

specific Embodiment approach 2

[0044] Embodiment 2: This embodiment is a further description of Embodiment 1. In the first step, the axis direction of the indenter determined by the single crystal diamond crystal blank is selected as the crystal orientation direction.

specific Embodiment approach 3

Abstract

The invention discloses a mechanical grinding process of a high-precision single-crystal diamond conical indenter, which belongs to the technical field of high-precision nano-indentation indenter manufacturing. The single crystal diamond crystal blank is cut and the cut surface is ground to make a single crystal diamond crystal; the single crystal diamond crystal is welded to the end of the indenter handle to obtain a single crystal diamond indenter; the tip of the single crystal diamond indenter is rounded It is a single crystal diamond conical indenter; rough machining of the conical surface; precision dressing of cast iron grinding discs and coating of diamond abrasive paste; stability of the performance status of the diamond tool grinding machine; the first finishing of the conical surface; The first finish machining; adjust the position of the jig rotation axis to coincide with the swing center of rotation; the second finish machining of the conical surface; the second finish machining of the ball head surface; use the atomic force microscope to detect whether the processing is qualified. The operation is simple, the cost is low, and a high-precision single crystal diamond conical indenter can be obtained.

Description

technical field [0001] The invention belongs to the technical field of manufacturing high-precision nano-indentation indenters, in particular to a mechanical grinding process for high-precision single-crystal diamond conical indenters. Background technique [0002] With the continuous advancement of the scientific and technological level of human society, the rapid development of MEMS manufacturing technology, bioengineering and thin film technology has put forward new requirements for the detection technology of mechanical properties of materials. plays a vital role in. Nanoindentation technology is an important technology for detecting the micromechanical properties of materials. Its main detection principle is to press a spherical or conical indenter into the surface of the material to be tested, and continuously record the indentation load and The indentation depth is used to characterize the micro-mechanical properties of the material by analyzing the load-displacement...
