Component Specifications

Definition
A precisely machined edge or planar surface on a feeder base that serves as a dimensional reference point for positioning components during automated feeding operations. This critical feature ensures repeatable alignment by providing a consistent contact point against which parts are registered, eliminating positional variability and maintaining tight tolerances throughout the feeding process.
Working Principle
The reference edge/surface establishes a fixed geometric datum that guides components into precise positions. When parts enter the feeder, they contact this reference feature, which constrains their movement along defined axes. This mechanical registration ensures each component assumes an identical orientation and location relative to the feeding mechanism, enabling subsequent operations like picking, inspection, or assembly to occur with high positional accuracy.
Materials
Hardened tool steel (AISI D2 or equivalent), stainless steel (304 or 316), or aluminum alloy (6061-T6) with wear-resistant coatings like titanium nitride (TiN) or chromium nitride (CrN) for durability.
Technical Parameters
  • Hardness 58-62 HRC (steel)
  • Flatness tolerance ≤0.01 mm
  • Dimensional accuracy ±0.005 mm
  • Surface roughness (Ra) ≤0.4 μm
  • Temperature stability range -20°C to 80°C
Standards
ISO 2768, DIN 7168

Frequently Asked Questions

What is the primary function of a reference edge/surface on a feeder base?

It provides a consistent mechanical datum for accurate and repeatable positioning of components during automated feeding operations.

How does wear affect reference edge performance?

Wear degrades dimensional accuracy, causing positional drift and misalignment, which necessitates regular inspection and maintenance.

Can reference edges be adjusted or recalibrated?

Some designs allow micro-adjustments via set screws or shims, but permanent references typically require remachining if damaged.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
