Product Description
Custom Non-Magnetic Alloy 4‑Hole Contoured Component Shaped Parts for Assembly & Tooling
Unlike standard rings, bushings or single‑bore inserts, the Non‑Magnetic Alloy Four‑Bore Contoured Component merges two difficult requirements into one: a non‑linear outer profile combined with multiple precision holes that must maintain exact positional relationships. This combination is demanding to machine, yet it is essential in custom fixtures, multi‑point alignment tools, EDM workholding and calibration standards where magnetic interference must be eliminated.
The "four‑hole shaped" part - when geometry complexity meets hole‑position precision, standard catalogs end and custom engineering begins. In automatic inspection, die‑set alignment and sensor fixtures, non‑magnetic properties are just part of the requirement; the real need is a single component that both positions and guides without magnetic interference.
Materials That Meet the Need
We begin with austenitic non‑magnetic alloys (300‑series stainless steels, high‑manganese austenitic steels, or WC‑Ni cemented carbide when hardness is critical) that remain non‑magnetic in service.
- μ < 1.002 permeability - verified when required
- Fabrication: multi‑axis CNC milling, wire EDM, sinker EDM
- Hardness options: from austenitic steel (HRC 25‑48) to WC‑Ni (HRA 89‑92) depending on wear and cutting resistance needs
- Anti‑corrosion: ideal for cleanroom, medical or fluid‑handling applications
Why "Shaped + Four Holes" Is Difficult - And How We Solve It
Unlike simple rings or rectangular bases, a contoured outer profile with four precision bores requires:
- Multi‑setup machining - each setup introduces potential misalignment
- Stress relaxation - removing material asymmetrically can cause distortion
- Hole‑to‑hole positional control - especially challenging when holes are not in a straight line
- Non‑magnetic property preservation - grinding or EDM can induce surface stress or magnetism if not controlled
How we solve it: Plan sequence from solid; use wire EDM for contour + bore positioning in one clamped setup; stress‑relieve after roughing; verify hole positions with CMM.
Key Applications (Where Both Shape and Holes Matter)
- Inspection fixturing (CMM / vision systems) - A curved or stepped carrier with four tapped holes to mount sensors or probes - non‑magnetic eliminates eddy‑current interference.
- EDM workholding (submersible fixtures) - Complex‑profile support with four flush or electrode mounting holes; austenitic stainless resists corrosion in dielectric fluid.
- Assembly jigs (multi‑part alignment) - A contoured base with four precision dowel holes that locate mating components - magnetic‑free avoids particle attraction on clean lines.
- Calibration / test standards - A uniquely shaped artifact with four reference bores for qualifying measurement systems.
- Magnetic‑sensitive automation (pick‑and‑place tooling) - Custom end‑effector mounting plate with four through‑holes and a non‑rectangular cut‑out pattern.
Core Capability & Differentiation
Our approach: machine the entire component from a single piece of non‑magnetic alloy, ensuring both μ < 1.002 permeability and permanent hole‑position accuracy.
