bit tree fixture 3d model

Tree-Shaped PVD Drill-Bits Fixture (“Bit Tree”) One-liner Maximize parts per cycle without sacrificing coating quality. This tree-shaped fixture holds drill bits vertically inside the PVD chamber to boost density, minimize shadowing, and keep loading fast. Description The Bit Tree is a vacuum-ready, space-efficient fixture engineered for PVD runs. A radial, tiered “tree” layout presents each bit to the targets with consistent line-of-sight while maintaining uniform spacing. Between tiers, the bit positions are twisted (staggered rotational offset) to reduce mutual shadowing. Each branch is set at a small outward tilt so that, when you load the fixture, the branches are oriented at a slight angle relative to vertical—improving side-flute exposure and film uniformity while aiding retention during rotation. Specifications Overall envelope: 5 × 5 × 20 cm (W × D × H) Bit seats: radius 0.75 cm (Ø 1.5 cm / 15 mm) Branches (holders): Ø 1.1 cm (11 mm) Branch tilt: small outward angle (~5–10°) relative to vertic
