Electronic copper parts

The characteristics of turning copper parts

Copper alloy machining (turning, milling) has excellent performance and low resistivity. Good ductility, high thermal and electrical conductivity, so it is the most commonly used material in cables, connectors, and electrical and electronic components. It can also be used as a building material and can be composed of many kinds of alloys. The most important of these are: beryllium copper, phosphor bronze, bronze and brass. In addition, copper is also a durable metal that can be recycled many times without compromising its mechanical turning and milling performance.

Development of micro-turning and milling parts

In recent years, civil defense and other fields demand for a variety of CNC machining miniaturization of products continues to increase, the function of the tiny devices, the complexity of the structure, reliability requirements are also increasing. Therefore, it is of great significance to research and develop micro-machining technologies that are economically feasible, capable of processing three-dimensional geometric shapes and diversified materials, and feature sizes ranging from micrometers to millimeters. At present, micro-cutting has become an important technology to overcome the limitations of MEMS technology.

CNC turning of medical titanium alloy parts

Design the correct CNC machining part program

The ideal CNC machining program should not only ensure that qualified workpieces conforming to the drawings are processed, but also should enable the functions of the CNC machine tool to be reasonably applied and fully utilized. The CNC machine tool is a highly efficient automation equipment. Its efficiency is 2 to 3 times higher than that of ordinary machine tools. Therefore, to give full play to this feature of CNC machine tools, one must master its performance, characteristics, and operating methods. At the same time, the machining plan must be correctly determined before programming.

CNC machining large aluminum cavity parts

Machining of large and thin-walled aluminum parts

For CNC machining of aluminum parts with a large margin (large, thin-walled, aluminum cavity parts), in order to have better heat dissipation conditions during the machining process and avoid heat concentration, symmetric machining should be used during machining. If there is a 90mm thick aluminum sheet that needs to be machined to 60mm, if one side is milled, the other side should be milled immediately, and the flatness can only reach 5mm after processing to the final size at a time;

How to solve the deformation of thin parts in CNC machining?

Turning and milling thin parts (aluminum, aluminum alloy, pure titanium, copper, magnesium alloy) are always prone to deformation during machining. Oval or “waist shape” with a small middle and large ends, which makes it difficult to ensure the quality of parts. Its clamping design is often the most discussed point. Let’s take a look at two design examples of thin-walled fixtures on turning and milling parts, and how they solve the deformation problem.

Machined Medical Titanium Components

Manufacturer of Machined Medical Titanium Components

The medical application of titanium as a material is constantly expanding, new application possibilities in the human body are constantly being opened up. Parts made of titanium are used for pins, screws, wires and rods, plates, grids and cages to moving parts with joints such as replacements for fingers or toes. Replacing bones and joints from milled titanium parts and titanium assemblies is a complex task, but surgery, orthopedics and dentistry are indispensable without implants made of titanium.
