Importance of CNC in Medical and Medicinal Industry

figure 1 what is the importance of cnc in the medical and medicinal industry

In the medical industry, several parts and components need to be made quickly and urgently, even in small quantities because they are used in different hospitals, clinics, and other different medical specialty branches.

Without CNC manufacturing, the production of medical, medicinal, and pharmaceutical parts and components will take more time, and they run the risk of not being accurate and precise. 

Understanding Medical Precision Parts

figure 2 what are medical precision parts

Medical precision parts are any parts of medical, medicinal, pharmaceutical – even aerospace parts that should be accurate and precise to the extent that they should have almost perfect tolerance levels. The way of producing these medical precision parts would be through using precision mills instead of regular CNC or standard mills.

In case you didn’t know, precision CNC milling is a process that is used to do the highly sophisticated cutting and subtractive operations using a CNC mill or a cutting tool in order to achieve the shape, form, measurement, and angles desired by a client.

Types of Medical Precision Parts

Medical precision parts refer to a multitude of components critical for different medical devices. These components are carefully designed to the highest standards of quality and precision, fulfilling safety requirements for medical equipment. This includes, among other surgical instruments, implantable devices such as orthopedic and cardiovascular implants com They also include microfluidic devices, respiratory equipment parts, dental equipment components prosthetics and orthotics as well as laboratory & research tools.

These high-precision parts are made of materials like stainless steel, titanium and plastics through precision manufacturing processes such as CNC machining 3D printing or injection moulding. To ensure the reliability and safety of these components in medical applications, they undergo stringent quality control measures as well as biocompatibility tests. Medical precision parts are essential in the healthcare industry, ranging from life-saving implants to sophisticated diagnostic tools used for providing quality medical care.machining medical parts 2

Machining Techniques Used for Producing Medical Precision Parts

The manufacture of medical precision components uses different machining processes in attaining the desired tolerances and meet very strict quality requirements. Relevant techniques include CNC machining, automating milling, turning and drilling; Swiss-type machining for tiny and delicate details; EDM that uses an electric spark on the materials such as titanium or stainless steel. Laser cutting and welding are used for shaping materials with low heat impact while grinding allows clear surface finishes of parts such as surgical instruments Wire EDM and electrochemical machining are deployed for complex geometries that are difficult to machine conventionally. Furthermore, 3D printing and injection molding satisfy custom needs for thermoplastic medical components while micro-machining techniques develop diminutive dull parts.

Such machining techniques are selected considering the particular needs of medical precision parts that may include material properties, tolerances, dimensional complexity and quantity to be produced. Collectively, these techniques ensure a reliable manufacturing of quality medical components that are critical to healthcare applications.

The Production Process of Medical Precision Parts

The process of making medical precision parts often involves the use of a high-precision CNC mill, which is not very different from how traditional CNC milling is made and done. To help you, though, here’s a brief overview of how they’re made, and here’s a quick and easy step-by-step flow of medical precision parts manufacturing.machining medical parts 5

  1. The materials are sourced and gotten by the manufacturer/supplier.
  2. Then, the machine that’ll be used should be programmed to the specific software or pattern needed to create the precision part.
  3. After that, the material will be loaded onto the CNC precision machine.
  4. A dry run method or process shall be done for testing to see if it has the program or the pattern embedded.
  5. When it reflects positive and accurate results, the precision milling process is started.

NOTE: Usually, at the end of medical precision parts manufacturing, an assessor or an expert will thoroughly check and inspect the quality of the produced parts and components to see if it is within the tolerance level that’s set. Otherwise, minimal modifications are to be done to the produced components.

Materials Used For Medical Precision Parts

figure 3 what materials are used for medical precision parts The materials used in producing and manufacturing medical precision parts depend on a few factors: (1) the type of material or part that is to be created, (2) the properties needed by the part or component. CNC medical precision milling is a highly flexible and versatile procedure, and it usually just revolves around metal and plastics. To be more specific, these are:
  • Different types of alloys
  • Stainless steels
  • Precision steels
  • Titanium
  • Brass
  • Specialty alloys
  • PVC
  • PEEK
  • Nylon
  • PTFE
  • PMMA
  • And many more!
So, there’s actually no “perfect material” used in medical precision parts supplication or manufacturing.

Pros and Cons of Medical Precision Parts

figure 4 what are the pros and cons of medical precision parts Made for their advantages and benefits, the medical industry can see a ton of advantages, benefits, or pros when it comes to CNC medical precision parts manufacturing. In fact, these advantages are:
  • Does Not Require Fixed Tooling
  • No Volume Restrictions
  • CNC Machines Are Flexible and Portable
  • CNC Machines Have Specific Tolerances
These are four (4) of the primary pros and benefits of CNC medical precision milling or manufacturing. But, wait, are there drawbacks or challenges linked to it? Well, of course, there are. CNC medical precision manufacturing can…
  • Have higher-than-the-usual initial costs
  • The complex and complicated manufacturing procedure
  • Bad or poor quality control
Just like any other industry, the medical or medicinal industry also has these factors to consider and give more thought in to ensure that the quality of products is just right.

Metals vs. Plastics For Medical Precision Parts

figure 5 metals vs. plastics for medical precision partsIn the medical industry, the use of plastics isn’t actually frowned upon, in fact, it is the other way around. Plastics have been widely known in the industry as better, lighter, and more flexible simply because of how they are structured and how their properties are.

Now, for some machines and equipment, metals are the most recommended because of their thermal conductivity, strength, durability, as well as electromagnetic properties, too.

So, if you’ll need to choose between plastics and metals, try considering the use or the end result you’re looking for.

Guidance for Custom Medical Precision Parts From Manufacturers

In that order when finding custom-made medical precision parts from manufacturers, first outline your requirements and identify qualified suppliers with appropriate accreditations only then ask for competitive quotation. Evaluate proposals due to cost, lead time duration as well as performance of the manufacturer. Implement quality assurance, following industry standards and fostering clear communication between individuals involved in the project. Prototyping for validation should be considered, and regulatory compliance needs to ensure. Specify contracts; perform quality inspections at delivery time, and provide feedback for continuous improvement along with great records of documentation to be used in an audit. Using this structured approach, it ensures that the procurement of high-quality custom medical precision parts is acquired based on the specifications and regulatory standards.cnc machining medical devices 5


Throughout the medical field, such precision parts are required to significantly increase accurate handling that involves certain technologies used in CNC machining and EDM. These items, critical components of devices and implants call for strict controls concerning regulatory matters. In the process of procurement, it is critical to choose suitable materials and suppliers that would align with high-end quality standards. The establishment of a more structured form, with careful communication and documentation enables successful collaborative ventures as well the availability for delivery to hospitals quality components.
