CNC metalworking is replacing other manufacturing technologies in multiple industries. The medical field is considered an area where mistakes are rare, and the same rules apply when it comes to manufacturing medical parts, because human lives are at stake in this field, and even small mistakes can lead to serious health problems or even death. Therefore, the machining techniques that machinists use to produce medical parts must support tight tolerances and high-precision measurements.

CNC metalworking is growing in popularity due to its ability to mass-produce detailed and precise results, which has led to an increase in the number of producers using CNC machines in the industry.

CNC machining is a manufacturing method in which the tool movement is controlled by pre-programmed computer software. All medical products can be manufactured accurately and quickly with the help of CNC milling and turning. Let's look at the main advantages of CNC machining demand in the healthcare industry:

No fixed tool

CNC machining is unmatched in terms of fast turnaround and minimal investment in small batch production, even in disposable products. Parts for the medical industry often have to be manufactured quickly and in small batches. At the same time, CNC metalworking allows parts to be manufactured without dedicated tools, which can extend the manufacturing process but provide excellent quality and precision even without the use of tools.

No quantity limit

After you create a digital CAD (Computer Aided Design) file, you can easily build a cutting program from it at the touch of a button. The coding application can manufacture a single part or any number of parts with the highest precision and accuracy. This is a huge benefit when creating disposable or disposable custom parts, such as highly specialized medical devices, appliances, equipment, prosthetics, and other medical or surgical products. Other procedures require a minimum order size to obtain the required raw materials, making certain projects impractical, while CNC machining does not require a minimum order size.

High tolerance

Many medical types of equipment require a large tolerance range, and with CNC machines, this is easily achieved. The surface finish is usually very good and requires minimal post-treatment, saving time and money, but this is not the most important consideration. In general, the most important thing to remember about medical supplies and equipment is that they must be fit for their purpose, and any deviation from the standard can mean disaster.

Fast machine
