Why choose CNC machining for the parts of endoscopic surgical robots?


Endoscopic surgical robots represent an advanced medical technology. These robotic systems can enter the human body through tiny incisions, providing three-dimensional high-definition images and flexible operations through high-resolution cameras and agile mechanical arms. This enables surgeons to observe and treat lesion areas more accurately during surgery. Endoscopic surgical robots reduce surgical trauma, enhance surgical precision, and shorten recovery periods, offering patients less pain and faster recovery. Additionally, they provide surgeons with improved surgical control and visibility.

What is CNC machining?

CNC stands for Computerized Numerical Control, also known as computer numerical control machining. It is a type of automated machine tool equipped with a program control system. The CNC control system processes programs specified by control codes or other symbolic instructions logically, decoding them to perform corresponding actions on the machine tool. This results in the machining of raw materials into parts shapes according to design drawings.

What are the CNC machining processes?

CNC machining includes primary processes such as turning, milling, grinding, planing, drilling, boring, complex surface machining, including drilling, reaming, tapping, external turning, boring, slotting, hobbing, thread cutting, flat milling, step milling, groove milling, gear milling, and cutting. Grinding includes external cylindrical grinding, internal cylindrical grinding, flat grinding, and thread grinding. Drilling, expanding holes, reaming, tapping, and countersinking are also part of the processes.

Which endoscopic robot parts are suitable for CNC machining?

Irregular parts, which have irregular shapes, are typically less rigid, and require mixed processing of points, surfaces, and lines. As such parts are challenging to ensure deformation and precision, CNC machining is necessary.

Disk, sleeve, and plate-type parts with distributed hole systems, keyways, radial holes, and axial surfaces. Ordinary machine tools are usually unable to process such parts, and CNC vertical machining centers or CNC horizontal machining centers are required for surface machining.

How to choose a CNC machining factory for endoscopic robot parts?

Precision parts require high technical expertise and experience, and only manufacturers with relevant knowledge and extensive experience can provide high-quality products.

Choose a factory with a quality management system and quality standards to ensure that products meet customer requirements and standards. Appropriate system standards can reduce the probability of trial and error for defective products.

For the medical industry, select a CNC machining factory with ISO 13485 certification, as quality assurance promotes development, saves time and costs, and protects one's interests.

In summary:

CNC machining enables high-precision part manufacturing, ensuring that the dimensions and shapes of medical parts meet strict requirements. CNC can process various materials commonly used in medical parts, such as PEEK, PEI, bioceramics, titanium alloys, aluminum alloys, magnesium alloys, etc. The use of CNC machining ensures the consistency and precision of mass production, directly impacting the sustained and stable operation of medical equipment, ensuring medical safety.

At AbleMed, CNC is the most experienced method for medical device part machining. Engineers' familiarity with the medical field can help manufacturers propose cost-effective machining suggestions before sample (prototype) manufacturing, enabling rapid market entry for medical parts.

Common questions:

Is the quality of endoscopic robot parts important?

The quality of endoscopic surgical robot parts is crucial for the overall performance and reliability of the system. High-quality parts ensure the stable operation of the robot system, reducing failures and maintenance frequency, improving surgical safety and success rates.

How can CNC machining costs be reduced?

To improve the production cost of parts, remember some tips. The more the quantity, the lower the CNC machining cost. Design and material optimization, part tolerance, and shape affect machining costs. Avoiding complex and strict parts as long as they meet functional requirements helps reduce costs.
