The Capabilities of CNC Machining

CNC machining is a precision manufacturing process that utilizes pre-programmed computer software to run the movement of machinery and other factory tools. This process allows for greater control over machine tool functions with little involvement from human operators or the risk of human error.

CNC machining is similar to 3D printing in that machines produce the components based on human design and input. But CNC machining offers the advantage of a wider range of materials, better precision, higher quality, and faster processing times than 3D printing. The medical industry, in particular, can benefit from the utilization of these machined parts with their superior accuracy and quality.

SJTI utilizes top-of-the-line full 5 axis and multi-axis machines for the creation of a variety of healthcare-related parts, including cardiovascular and orthopedic devices, surgical instruments, and medical screws. Our six full 5 axis machines are capable of producing the highest quality precision machined parts with increased speed and superior surface finish.

Additional examples of CNC machining applications in the medical industry are listed below:

  • Medical implants
  • Testing & analysis components
  • Medical instrument components
  • Respirator device components
  • Ventilator components
  • Drug deliver components
  • Pump components
  • Complex multi-component assemblies
  • Precision shafts
  • Brass inserts
  • Spacers
  • Fittings
  • Valves
  • Capstan
  • Cough assist
  • Oxygen Sensor
  • Blower Mounting
  • Bulkhead
  • Flexure
  • Precision Spacer

The Capabilities of Medical Additive Manufacturing

In addition to the amazing capabilities of CNC machining, at SJTI, we also employ additive manufacturing techniques when needed. We utilize state-of-the-art 3D printer technology where applicable for prototyping and small printing jobs.

Additive manufacturing, or 3D printing, builds a three-dimensional object with the assistance of a computer-aided design model. Additive manufacturing facilitates rapid prototyping, provides an economical method of producing complex assemblies for molded products, and offers versatility in manufacturing.

Additive manufacturing is especially useful for the medical industry where a small production run of a thermoplastic or resin part is needed with a quick turnaround time.

 Medical additive manufacturing such as surgical mask clips can be easily and rapidly produced in a cost-effective manner with medical additive manufacturing services. Other medical parts that can be created using 3D printing include implants, surgical tools, and prosthetics.


At SJTI, we have produced custom and unique parts for a variety of industries, with everything from standard steels to exotic materials.

Some of the materials we typically work with include:

  • Aluminum
  • Carbon steel
  • Stainless steel
  • Titanium
  • Inconel
  • Monel

We offer a wide variety of materials for CNC machining applications in the medical industry, including the most commonly used plastics, metals, and nylons.
