Current Process

Kirschner wires, also commonly known as K-wires, are ground using a manual OD grinder.


Low production output, as only one wire can be ground at a time. Changeover between wire diameters is time-consuming, delaying production. Grinding can leave burrs requiring secondary processes to deburr, lengthening production time.


Solution: Burr-Free Electrochemical Grinders (ECG) SG-1645 or SG-2060, ECG Point Grinding System PGS-100 from Tridex Technology, A Glebar Company

ECG provides burr-free and low-force cutting for applications with tight tolerances and heat sensitivity. The PGS-100 can be added to the SG-1645 or SG-2060 to grind points on the wires in large batches. For example, at .065" diameter, 55 K-wires can be pointed in one batch at a cycle time of approximately 2.2 seconds each. Changeover from one diameter to another takes only 5 minutes. Changing point geometry only requires a simple CNC program edit.

For K-wires that require multiple profiles, Glebar recommends its CAM.2 Microgrinder.

  • Reduces machining time, increasing output.
  • Significantly lengthens wheel life, reducing consumables costs.
  • Eliminates the need to deburr, reducing production time.
  • Allows machining of various tips, including trocars, drills, multi-faceted, etc.
  • Plain or threaded parts can be produced with the same accuracy.
  • Capable of grinding almost any point geometry on exotic and difficult to machine materials.
  • The same process can be applied to grinding Steinmann Pins.

When added to our Tridex SG-1645 or SG-2060 electrochemical grinders, the PGS-100 is a fully programmable pointing and material handling system to manufacture a wide variety of medical device points on tubing or solid wire, such as medical needles or K-wires, using electrochemical grinding technology (ECG).
