Production series of modular structured timber processing plants that were introduced in 2002 by Weinmann.

Typical for this production series is a three-part devision (three stages of expansion):

• Stage 1: Pure sizing saws, for example, WBZ 100, WBZ 110
• Stage 2: Machines extended by milling and drilling, for example, WBZ 120, WBZ 130
• Stage 3: Flexible timber processing center with diverse equipment options for trimming, for example WBZ 150, WBZ 160
