Raute Veneer Peeling Knife Replacement Blades
Raute peeling lines are built for continuous output, which means the knife is changed on schedule rather than when the veneer looks bad. We supply peeling knives and pressure bars made to your drawing, with the edge angle set for the species you peel.
The knife and the bar are a pair
On a peeling lathe the surface is produced by the knife edge and the pressure bar working together, with the gap between them set slightly under the veneer thickness. A new knife against a worn bar will not deliver a clean face, so we quote them together where the bar is also due.
| Part | What we need | Typical reason for replacement |
|---|---|---|
| Peeling knife | Length, height, thickness, hole pattern, edge angle | Edge rolled or nicked; thickness drift on the sheet |
| Pressure bar | Length, section profile, mounting hole pattern | Nose worn or chipped; gap no longer holds a setting |
Specification range
Peeling knives from 1500 to 3000 mm in length, in HSS, BF anti-bluing white steel, 2HS and tool steel; hardness HRC 57–62; edge straightness within 0.05 mm over the full length. Longer and wider knives are made to drawing.
For mills peeling pale hardwood for face veneer, the BF anti-bluing surface is worth specifying: it removes the staining variable from your quality losses.
Setting up a new knife on the lathe
Most complaints about a new peeling knife turn out to be setup rather than steel. Before judging the knife, confirm three things: the knife angle against the machine's specification, the pressure bar gap at thickness minus 0.05–0.10 mm, and the bar pressure raised only until torn grain stops. Our peeling knife setup guide covers the symptoms and what each one points to.
Consumable planning
Continuous lines usually run two knives per shift, regrinding in rotation. Two things make that work: consistent edge angle across every knife in the set, and enough body thickness for several regrinds. Tell us your change interval and the number of regrinds you expect, and we will size the knife and the steel grade for that cycle instead of selling the hardest edge available.
Frequently asked questions
Do you make both the peeling knife and the pressure bar?
Yes, both are manufactured in-house, which is why we recommend quoting them as a pair when either is near the end of its life. A knife that is correct but matched to a worn bar will still produce torn veneer.
Can you supply knives to the original drawing?
Yes. Send the drawing as PDF or DWG and we produce to it. If you only have the machine model, we will issue a drawing for your approval before cutting steel.
What lead time should we plan for?
Common sizes are held for fast shipment; made-to-drawing knives typically two to four weeks. Mills that run continuous shifts usually keep one knife set in reserve rather than order against a breakdown.
Can a worn peeling knife be reground more than once?
Yes, while body thickness allows for the clamp and the machine's minimum knife height. Send the current width and thickness and we will tell you how many grinds remain.
