Precision is a necessity in the medical industry, as every component is crucial. There is no chance for any error as it’s a matter of life and death for someone. This is where CNC-machined medical parts come into play.
Gone are the days, when the CNC machine shop owners used to rely on traditional machining. This method is prone to error and fails to meet the exact standards of the medical machined parts.
In this article, we are going to look at how precision CNC machining is critical for medical devices.
What is CNC Machining and the Importance of Precision in the Medical Industry?
Everyone has heard about CNC machining and has an idea about it, but here’s a definition for it:
The process plays a vital role in the medical industry by producing highly precise CNC machining parts that doctors rely on for critical procedures. For instance, imagine a doctor needing a tiny, intricately shaped part for a life-saving surgery. This is where CNC machining steps in, delivering the precision and accuracy required to make such components possible.
Here are some of the benefits:
- High Accuracy: CNC machining delivers parts with exact specifications, which is crucial for the precision required in medical devices.
- Consistent Repeatability: Ideal for large-scale manufacturing, CNC machining ensures every part is identical and accurate.
- Complex Designs: Capable of producing intricate geometries that traditional methods cannot achieve.
Key CNC Machining Techniques for Medical Devices
- Turning: Turning is a CNC machining technique where the workpiece rotates while a cutting tool shapes it into the desired form. It’s perfect for creating cylindrical parts like screws, pins, or tubular components, especially when tight tolerances are essential.
- Electro Discharge Machining (EDM): EDM (Electrical Discharge Machining) is a CNC technique designed for machining hard materials that are tough to process using traditional methods. It’s commonly used in the medical field to create precise parts like stents, surgical instrument components, orthopedic screws, micro-needles, and more.
- Milling: Milling is a highly versatile CNC machining process that uses rotating cutting tools to shape and remove material from a workpiece. It’s useful for creating complex parts, making it ideal for producing custom surgical instruments and implantable devices used in medical equipment.
Examples of CNC Machining Parts for Medical Devices
Surgical Instruments
CNC machining is ideal for creating precision surgical instruments like scalpel handles, forceps, and scissors used in minimally invasive procedures. These tools help doctors perform complex surgeries with smaller incisions, leading to less scarring and quicker recovery for patients.
Implants
CNC machining is perfect for producing a wide range of implants, including orthopedic, dental, and spinal implants. These parts require exceptional precision because they’re used in the human body, where accuracy is crucial for safety and effectiveness.
Diagnostic Equipment Components
CNC machining is ideal for making components used in diagnostic equipment, such as housings for CT scanners, MRIs, and parts for patient monitoring systems. These components must meet strict precision standards to ensure the equipment operates reliably and accurately for patient care.
Prosthetics
CNC machining is essential in making custom prosthetic limbs, as each part needs to be tailored to the unique needs of the patient. With its high precision, CNC machining ensures a perfect fit, comfort, and functionality, helping create prosthetics that closely mimic the natural movement and appearance of the human body.
Materials We Work With
At MDA, we use a variety of materials to produce high-quality medical CNC-machined parts, ensuring they meet the highest standards of precision and durability.
Titanium
Titanium is commonly used for medical machined parts because it’s lightweight, strong, and highly resistant to corrosion. Its biocompatibility also makes it safe for use inside the human body, ensuring both durability and safety in medical applications.
Stainless Steel
Stainless steel is a top choice for medical machined parts because of its excellent resistance to corrosion and durability. It’s ideal for surgical instruments, implants, and diagnostic equipment. Another key reason CNC machine shops prefer stainless steel is that it can withstand sterilization processes without losing its integrity or quality.
Aluminum
While aluminum isn’t the best choice for implants, it’s a great option for other medical applications. Its lightweight nature and excellent machinability make it ideal for components like medical equipment housings, where strength and ease of manufacturing are key.
Ceramics
Ceramics like zirconia are commonly used in dental implants and joint replacements because of their hardness, biocompatibility, and excellent wear resistance, making them ideal for long-lasting and safe medical applications.
