CNC Machining for the Medical IndustryWhen it comes to the components that are manufactured for the medical industry, accuracy is vital. This statement is true of the manufactured parts that span the entire industry. Whether it be medical equipment, biomedical implants, medical instruments such as catheters, ultrasound equipment, MRI scanners, or diagnostic equipment – you name it, high precision CNC Machining will have played its part.
What is CNC Machining?CNC Machining is the process where Computer-Aided Design (CAD) templates are manufactured via an automated program. A CNC machine follows a coded program with no manual input and creates complex parts from raw material through subtractive machining technology. Simply put, this involves automated machines and cutting tools crafting a final product by cutting away at the workpiece or ‘blank’. CNC Machining is widely acknowledged as creating parts with far greater accuracy, durability, and precision than other machine processes that involve manual processes.

Ways CNC machining can be used in the Medical SectorCNC Machining is used in the medical sector as it meets the uncompromising requirements of quality and consistency. Complex surfaces and geometries aren’t a problem and final pieces strictly adhere to the safe and precise needs of the medical industry. Medical machinery is complex, requiring parts that are up to scratch with no room for error. Parts must be durable, of the highest quality, and with a smooth finish. CNC machining achieves just that, as the machines operate on multiple axes. What’s more, complicated designs can be manufactured on a large scale and can be suitable for mass manufacturing.
Machined medical implantsThe overarching requirements of any piece of medical hardware have the same criteria; the final product must adhere to stringent quality standards, with accuracy, quality and consistency across the board. This high level of accuracy can be achieved through CNC machining, which is why as a sector, the medical industry relies on CNC machining on a large scale. The health of the patient and recipient are at risk if these needs aren’t met, which is why there is such heavy reliance on CNC Machining for medical devices and parts. CNC machining for medical can also be used for surgical instruments, as well as complex pieces of equipment such as heart rate monitors, X-Ray monitors and MRI scanners. Due to the range of finishes that are available with CNC machining, more bespoke products can also be created. Plastics, for instance, are used on a large scale in the medical industry.
