The feature 'veneer sanding' refers to the adequacy of wide belt sanders for sanding veneered surfaces before the paint job.

Problems

• Veneer is thin, has a high quality, and the structure should be preserved
• Sometimes special forms
• Workpieces are already almost done/expensive, when they are sanded
• At the edges, a higher sanding pressure works. There is a danger of sanding through, i.e. the veneer is sanded off and the support material comes to light.

Machine equipment

• Width not less than 1.000 mm. Ideal are 1.100 to 1.300 mm.
• Cross belt (not required)
• 1-3 sanding pads: a minimum requirement are air cushion pads, segmental pressure pads are optimal, operational control is also required; rigid sanding pads are unsuitable
• Brush for workpiece cleaning or satin finishing

Soft rubber contact rollers are used for the sanding of thick veneer (very rarely, only special machines). Better are somewhat softer sanding pads which achieve the same result and can be used more flexible.

Machine set: table resilient, pressure bar fixed.
