Efficient Surface Finishing Techniques When Working on Medical Items

Surgical instruments and tools The constant demand for medical instruments, which are properly sterilised and meet high standards of functionality, has made surface finishing an essential element in medical technology. By using the right techniques, you can grind, smooth, and polish orthopaedic components with high precision to recommended shapes and sizes and for maximum hygiene. 

Syntech and other experts noted that surface finishing plays a central role in the manufacturing of high-quality orthopaedic items, particularly small and delicate parts that demand a high level of precision. Examples of these include stents, elbow plates, dental and femur-screws, and dental and vertebral implants.

Vibratory finishing

This requires the use of rotary vibrators to either grind or polish medical items. The main advantage of using this method is that every component embeds completely in the polishing media, like when media cushions each part from excess friction when they get into contact with the other parts.

As this technique is quite rough, you will need to mount delicate and special implants on its fixtures to secure your work before beginning the finishing process. This is so that you don't compromise the functionality of these parts.

Drag finishing

This method uses spindles with already mounted workpieces, which drag through and rotate in a bowl with abrasives to finish particular parts. This technique is a little rougher than vibratory finishing, so you will need to attach items to a fixture before mounting them on workstations. This is regardless of the medical component you are grinding, smoothing or polishing.

This drag technique, however, attracts more applications than the vibratory method since it takes less time to program the finishing equipment. The end products of the dragging process also have a higher consistency than those you get from the vibratory process.
