Needle Grinding from Wytech

Wytech has diligently advanced its precision grinding capabilities over the last several years and is well qualified to meet the precision grinding requirements of most medical device wire and tubing component jobs, including needle grinding.

Hypodermic, stainless-steel tubing is one of the most common materials used in medical devices, one of those being the hypodermic needle. Wytech’s proprietary 5-Axis systems produce unique, multi-profile grinds and features not possible with conventional tip or point grinding equipment. Particularly, Menghini features or skived and scalloped tubes with varying grind angles for biopsy, aspirator needle sets, and more are ideally suited for Wytech’s FlexGrind program.

  • Types: bias grinds, lancet points, blunt ends, trocars, bevels, diamond points, trephine, and other unique tip geometries and profiles
  • Needle Tip: typical A & B bevel syringe-type grinds. A bevel is considered any ground surface of a cannula.
  • Point Grinding: conical point for wire
  • Chemical-etch marking and anti-core capabilities

Applications of Specific Needle Grind Types

Precision is important when it comes to needle grinding. Because of the invasive nature of needles in medical applications, ensuring the needle grind is flawless is essential to the patient’s comfort. From the common lancet found in most medical offices to the trocar commonly used in laparoscopic surgery, Wytech’s advanced technology will assure that all needle grinding is completed to your exacting standards.
