Straightening
Address bar straightness against the specified measurement length and TIR requirement before the next machining or assembly operation.

Centerless bar grinding
Precision starts
with the bar.
Diameter, straightness, and surface finish matter long before the finished part. Bring your bar requirements to K-O for grinding and the processing that comes next.
A better starting point
Bring the bar
to your specification.
Centerless grinding removes material from the outside of a round bar while the bar is supported between a grinding wheel, regulating wheel, and work support. The result is a controlled diameter and surface, ready for the next operation.
We plan the work around your material, incoming condition, finished dimensions, and delivery requirements. Send your own bar or ask K-O to source material for the program.

shape your program.
Start with the dimensions your application needs. We’ll review the combination of material, size, finish, and stock removal before confirming the processing plan.

Capabilities vary with material, incoming condition, diameter, length, and stock removal. Limits are not necessarily achievable together. Include the surface-finish metric and units with your drawing.
Material selection
Different materials.
Your exact requirements.
Explore material families for your grinding program. Share the exact alloy, specification, condition, and certification requirements so we can review the right route for your bar.
Bar processing
More than a
finished diameter.
Build the processing plan around what your operation needs to receive. Grinding can be combined with preparation, finishing, and packaging to support the next step.
Saw cutting
Prepare the lengths you need for production or delivery. Include cut length, length tolerance, quantity, and end-condition requirements.
Explore precision saw cuttingChamfering
Prepare one or both bar ends to the required chamfer. Specify the angle, size, and end detail for the next operation.

Heat treatment, plating, and finishing to suit your part requirements, with packaging and handling planned to protect ground surfaces through delivery.
The people and process behind the bar
A clear plan.
From receipt to release.
Our team reviews the incoming material and the finished requirements together. That keeps grinding, related operations, inspection, and delivery aligned with your program.
Every project is managed through K-O’s quality system. Required inspection records, material identification, and handling details are established as part of the agreed work.
