Needle Point

During the manufacturing process the needle tip is ground from metal rods. The finished needle should be free from burrs on the cutting edges (outside) and the rims (inside) produced from the grinding process. If burrs exist, this may result in increased pain and prolonged healing for the patient. Needles should be inspected to determine if burrs are present after the grinding process.

Vision systems are also used to measure the bevel angle of the needle tip. The angle will determine the sharpness of the needle. Needle sharpness is significant when it comes to needle performance. A sharp needle should result in less trauma during use.

Measuring systems that use flat field telecentric optics and with controllable illumination helps create a sharp image and the ability to focus on both the bevel and the needle tip at the same time. Having a range of illumination options is critical when measuring the reflective surface of the metal. If inspection, deburring and video measurements are to be done at the same time, dual optical inspection and measurement systems are ideal for the task.
