Re-Grinding Gear Hobs vs. Replacing Them: Which Saves More Money?

• Hob design
• Original material
• Amount of wear
• Grinding quality
• Production conditions

Reduced Downtime

Ordering a replacement hob may involve manufacturing and delivery lead times.

Re-grinding can often restore an existing tool much faster, helping maintain production schedules.

Sustainable Manufacturing

Reusing cutting tools reduces material consumption and manufacturing waste.

Many companies now include tool refurbishment as part of their sustainability initiatives while also lowering operational costs.

When Re-Grinding Is the Best Choice

Re-grinding is recommended when:

• Wear is uniform across the cutting edges.
• No cracks are present.
• Tooth geometry remains intact.
• The hob has sufficient material remaining.
• Cutting performance has gradually declined rather than failed suddenly.

A skilled gear hob manufacturer or reconditioning specialist can evaluate whether the tool can be restored without affecting gear quality.
