What are the applications of CNC machining in medical parts?

What are the applications of CNC machining medical parts? With excellent technology and advanced equipment, Xiehe has become a large number of precision parts for CNC machining of medical parts.

The following are the applications of CNC machining medical parts:

Handheld Devices, Surgical Instruments, Medical Carts, Electronic Instruments, Medical Diagnostic Equipment, Ultrasound Equipment, Medical Monitoring Instruments, Laser Equipment, Medical Equipment, Physiotherapy Instruments, [**]natomical Models, MRI Equipment, Tablets and Panels, X-ray Equipment, Teaching [**]ids , clinical analysis equipment, nursing equipment, etc.

The reason for customization?

1. The required parts are not standard and cannot be obtained directly from the supplier.

Parts may not exist elsewhere for many reasons. In many cases, when engineers create a novel production project, custom machining is required, and the individual components of the project cannot be purchased from suppliers, or the price is unreasonable. These parts may be as simple as gears or buttons of a non-standard size or material. They may be completely new inventions.

2. The required part has a unique function that the standard part does not have.

For completely generic parts that happen to have special requirements, custom machining may be required, such as custom adapters, additional features or text engraving.

3. Multiple elements can be combined into one section.

In many cases, custom machining is used to manufacture parts with multiple features or large parts. Because these parts are custom and ordered for specific projects, they can be heavily biased towards a specific end use. Standardized or common components are not useful.

4. High-quality parts can be manufactured in time in emergency situations, and small batches are acceptable in the machining workshop.

Whether it is metal processing (aluminum, brass, stainless steel, etc.) or plastic processing, it has all the usual advantages and functions of CNC on-demand. Even in emergency situations, high-quality parts can be produced quickly thanks to short setup times and low minimum order quantities.

How to achieve customized processing in the medical industry?

1. Material selection

There are many CNC machining materials. Which material should be chosen for medical and dental equipment? When choosing the best material for CNC medical components, factors such as the load, stress, shock and temperature that the product needs to withstand, as well as the size and weight of the component should be considered.

For example, the materials used to manufacture implants should meet stringent biocompatibility and sterilization requirements.

Different medical devices have their own most suitable materials. For example, for implants, the best materials are titanium alloys, cobalt-chromium alloys, stainless steel, PEEK, etc. Titanium alloys (Ti6[**]l4V), SUS alloys (SUS630, SUS420J2, SUS440C), aluminum alloys ([**] 2000 series, [**] 6000 series) and resins are suitable materials for surgical instruments.

2. CNC machining process selection

Simply put, custom machining is all forms of CNC machining—CNC milling, CNC turning, EDM, etc., with the express purpose of making parts that don’t exist anywhere else. Milling is a machining process that uses a rotating multipoint cutting tool to remove material from a part.

In CNC milling, the CNC machine usually feeds the part in the same direction as the tool rotates, while in manual milling, the machine feeds the part in the opposite direction as the tool rotates. The operational capabilities of the milling process include end milling (cutting into workpieces with shallow, flat surfaces and flat bottom cavities) and perimeter milling (cutting into workpieces with deep cavities, such as grooves and threads).

Turning is a machining process in which a single-point cutting tool is used to remove material from a rotating workpiece. In CNC turning, the CNC lathe feeds the tool in a linear motion along the surface of the rotating part, removing material from the circumference until the desired diameter is reached to create the internal features of the part with outer and inner cylinders, such as grooves, tapers, and threads . The operational capabilities of the turning process include boring, facing, grooving and thread cutting.

3. Select when finished

Most of the medical device shells are appearance parts, which usually require painting, sandblasting, silk screen printing, laser etching, anodizing, powder coating, etc. Some precision parts prefer machining to ensure assembly.
