However, the manufacture of hand-made customized devices can be more expensive or take more time. On the other hand, CNC machining allows companies to run the process without sacrificing delivery speed and quality smoothly.

2. Micromachining

Micro-machining is concerned with the manufacture of unusually small-sized medical components. These components are widely used in implantable devices and many others. Micro-machining can manufacture tiny surgical parts or tools. Some of the common examples of micro-machining are as follows:

1. Drug delivery systems

2. Catheters

3. Pacemaker components

4. Stents

5. Miniature screws for devices and implants 

Despite their small size, these machines are highly refined, requiring great accuracy and competence.

3. Implants

Most medical professionals try to provide the best possible treatment to their patients. But, in addition, they also ensure the comfort and well-being of patients at the same time. For this purpose, they need practical and durable medical equipment. Therefore, the machining of those types of surgical tools should be more precise. And it is beneficial to make reliable and robust medical tools that people can repeatedly use for up to several years. 

CNC machining is one of the robust tools used by both groups, medical professionals and machinists. For example, medical professionals usually perform surgery on patients' bodies where they need implants. These implants can be made by employing machine-made processes. Therefore, they used 3D printing or other methods to manufacture high-quality tools.

Here are examples of some standard implants:

1. CSF (Cerebral Spinal Fluid) Shunt Systems

2. Breast Implants

3. Phakic Intraocular Lenses

4. Hernia Surgical Mesh Implants

5. Cochlear Implants

6. Essure Permanent Birth Control

7. Metal-on-Metal Hip Implants

8. Urogynecologic Surgical Mesh Implants

4. Crucial medical equipment

CNC machines produce all the necessary equipment that is our needs in the modern world. Some essential equipment amongst many necessary tools is MRI scanners, X-ray machines, and heart rate monitors. All these tools consist of thousands of individual parts, and medical instrument manufacturers can make these parts through CNC machining.

Some widely used medical equipment are as follows:

1. Electric wheelchairs or manual wheelchairs  

2. Hospital beds
