What is Centerless Grinding?

Centerless grinding is a precision manufacturing process used to produce consistent wire diameters and smooth surface finishes without requiring the part to be held between centers.

The process allows long wire lengths to be ground with excellent dimensional consistency, making it ideal for guidewires and precision medical wire components.

Tight Tolerance Wire Grinding

Precision centerless grinding produces tight diameter tolerances required for consistent device performance.

• Tight diameter control

• Smooth surface finish

• Excellent concentricity

• Long production lengths

Controlled grinding processes reduce variation and improve performance consistency in medical device assemblies.

Taper grinding produces controlled flexibility along the length of guidewire core wires and mandrels.

• Single tapers

• Multi-stage tapers

• Linear tapers

• Stepped profiles

Precision taper transitions allow engineers to optimize flexibility and torque transmission.
