Medical Machining: Processes and Equipment

Medical machining creates the tools used in hospitals, doctors’ offices, and other medical centers. Groups researching and designing medical implants for new procedures will contact milling factories, to order prototypes. CNC machining mills are used to produce many types of equipment. Cannulas, implants, and IVs are all created at these mills, in large quantities.

In addition to making medical components, milling companies also provide engineering support, and testing. Engineers will meet with clients to refine a prototype’s design, advise them about materials and construction needs, and reduce overall production costs. At Aztalan Engineering, our engineers and designers work with clients daily to improve their prototypes for manufacturing and eventual sales.


Computerized numerically controlled (CNC) milling machines are the centerpiece of medical machining processes. Using pre-programmed designs, the machines will create different components out of specified materials. The design and rate of production can be changed as needed during the production process.

A CNC milling machine uses turning lathes to cut the base-material precisely, according to a product’s design. Based on its diameter, the lathe will use a suitable tip to cut components out of their base materials. Aztalan Engineering’s CNC smallest lathe will cut at a diameter of .125 inches, making our equipment perfect for manufacturing metal tubing. Using such a narrow diameter allows our machines to cut at a higher precision. These machines allow us to produce up to 2,000 individual units of product at a time.

Quality Control

During the machining process, engineers will perform frequent checks, to prevent production errors, ensuring a high-quality product. Before manufacturing begins, the prototype will undergo theoretical testing, based on its design, dimensions, construction, and base materials. Throughout production, samples will be inspected to check the final batch for errors, and maintain high-quality throughout.

In medical machining, frequent inspections are vital to creating a useful, sanitary product. After construction, medical equipment must be specially cleaned to meet medical sanitation requirements. Ultrasonic cleaning will remove bacteria and other pathogens from both the inside, and outside the tube. This will also eliminate particles, and other microscopic contaminants. Once the product is finished, it will be shipped to be used by customers in the medical industry.
