The Importance of Precision in Medical CNC Machining

The Importance of Precision in Medical CNC Machining

CNC machining is a precision solution that is well suited to medical equipment manufacturing. When medical devices and tools are being made, each machined part involved in its production must be produced within tight tolerances. There is no room for error in this process and the programmability of the CNC machining centers we use at Modern Industries helps to ensure quality on each production run we complete. If you want to learn more about the importance of precision in medical CNC machining, we have put together valuable information below. If you know you need parts for medical equipment machined precisely and promptly, you can skip reading and contact us today to begin a conversation and request a quote.

Types of Medical Products CNC Machines Can Produce


When it comes to making high performance medical instruments, CNC machining often plays a vital role in production. We will now explore just a few segments of medical device manufacturing that rely on CNC machines to produce equipment. At Modern Industries, we are an ISO 9001:2015 certified machining company that has over 75 years of engineering experience. You can contract our team of skilled CNC machine operators to manufacture many of the parts listed below along with other medical device components.

Surgical Instruments

CNC precision machining generates a range of quality surgical tools that healthcare professionals can use for diverse applications. Examples of CNC-machined surgical tools include:

  • Cutters
  • Forceps
  • Handles for blades
  • Holders for implants
  • Surgical scissors
  • Tubing for biopsies

Medical Implants

Medical professionals often require high-quality implants for patients to help maintain their well-being. 3D printing and machining methods like CNC machining help produce these devices for surgeons to utilize in many different procedures, with such examples as:

  • Facial reconstruction implants
  • Heart valves
  • Knee and hip joint implants
  • Stents
  • Ventricular assist devices (VADs)

Critical Healthcare Equipment

The medical field relies on the precision of CNC machining processes to produce different types of essential equipment, as well as their individual components or housings. Some examples include:

  • Heart rate monitors
  • Medical testing equipment
  • MRI and CT machinery
  • Ultrasound components and systems
  • Ventilator parts
  • X-ray machines

Micromachined Components

CNC machining can also produce micro-components and -tooling for medical device applications such as implants. The small parts that micromachining creates for the medical industry include:

  • Catheters
  • Parts for pacemakers
  • Small implant screws
  • Stents
  • Systems for drug delivery

When manufacturing parts with micro components, an even higher degree of precision is needed, and only certain CNC machining centers are suited to this work. 

Benefits of Using Precision CNC Machining for Medical Devices


Historically, medical devices had to be made using manual machining methods. Unfortunately, even the most skilled manual machinists are limited in the precision they and their equipment can ensure. However, with the advent of CNC machining, the skill of machinists was extended by the precision that programmable multi-axis machining centers provides. The innovation allowed by these advances exemplifies the importance of precision in medical CNC machining. Some of the benefits of CNC machining in the medical product manufacturing process include:

  • Enhanced accuracy and uniformity. Regardless of production volume and speed, CNC machining creates products with consistent, precision accuracy in a single batch. You can meet throughput goals and production deadlines without compromising on quality.
  • Improved efficiency, speed, and production volume. CNC machines can quickly complete multiple processes at the same time, allowing for higher production volumes along with increased overall efficiency.
  • Minimal risk of error. CNC equipment operates on its own once operators program its software and start the machinery. With minimal human intervention, you remove or greatly limit the risk of human error in a process that’s already highly precise.
  • 3D printing and prototyping. Using CNC machining, businesses also benefit from reliable 3D modeling and rapid prototyping capabilities to help perfect end products prior to full-scale production.
  • Reduced material waste. Unlike manual manufacturing processes, the level of precision in CNC machining helps limit waste generation. This has the added benefit of reducing material costs.
