This custom indexing plate is engineered from premium 6061-T6 aircraft-grade aluminum alloy as the standard base material, precision machined in a single 5-axis CNC operation to eliminate all secondary alignment errors. Every pocket, locating bore, and clamping slot on the plate is milled in one continuous setup, resulting in near-zero cumulative tolerance across the full 360° working face.
Built for high-repeatability rotary positioning in automation, 5-axis machining jigs, quick-change fixture systems, and metrology inspection stations, this part delivers consistent indexing accuracy even under continuous heavy cycle loads.
✅ Highlight Annotation: The entire plate retains full bulk material grain structure with no thermal deformation post-machining, which is the core difference between standard off-the-shelf plates and this custom high-performance version.

We do not limit this part to aluminum: the same fully-optimized machining workflow supports a full range of engineering materials, tailored directly to your application environment:
Material Option | Key Benefits for This Indexing Plate | Typical Use Case |
|---|---|---|
6061-T6 Aluminum (Default) | High strength-to-weight, excellent vibration damping, natural corrosion resistance, low inertia for fast rotary cycling | General automation, light-to-medium CNC workholding, 3D printer / CNC router quick-change systems |
7075-T6 Aluminum | 30% higher tensile strength than 6061, same low weight, higher rigidity | High-torque rotary axes, heavy load machining jigs, high-cycle 24/7 production lines |
6061-T6 Hard Coat Anodized | 400+ HV surface hardness, wear resistant, non-marring contact faces, easy to clean | Metrology inspection fixtures, cleanroom environments, high-frequency clamp/unclamp stations |
17-4 PH Stainless Steel H900 | Ultra-high rigidity, zero flex under extreme load, full corrosion resistance, non-magnetic option available | Heavy machining, aerospace fixture systems, harsh coolant / chemical processing environments |
PEEK / Engineering Thermoplastic | Non-marring, electrically insulating, zero scratch risk on soft workpiece surfaces | Precision assembly for polished parts, optical component fixturing, ESD-safe cleanroom lines |
✅ Highlight Annotation: Every material we machine for this plate uses a dedicated custom toolpath and feed rate profile, no generic one-size-fits-all G-code — we eliminate tool chatter, witness marks and residual stress before the part ever leaves the machine.
Every feature on this indexing plate is designed for real production performance, not just aesthetics:
Symmetric 8-station layout on perfect 360° pitch circle
No uneven weight distribution, no unbalanced vibration at full rotary speed. Each station can carry a separate fixture or workpiece, and you can index every 45° with absolute repeat alignment.
Dual-contact clamping slot profile
Every open slot on the plate uses a two-step machined profile: one face locates the fixture radially, the second face locks it axially. No slop, no play, no drift even after 10,000+ clamp cycles.
Perimeter distributed locating dowel grid
The 16 small precision holes around the outer edge form a universal datum grid. You can add custom stops, clamps or reference markers anywhere around the plate without re-establishing the main machine datum.
Single-piece full stock machining
No welded assemblies, no bolted-together layers. The entire plate is cut from one solid monolithic billet, so there is zero risk of delamination, shift or separation under load.
Back face full flat grinding
The rear mounting face is surface ground after CNC milling, ensuring total perpendicularity between the mounting face and every feature on the front face — no shimming required during installation.
✅ Highlight Annotation: Most off-the-shelf indexing plates skips the final back-face grinding step. This single operation adds less than 10% to the lead time, but eliminates 90% of all common setup errors users run into after mounting the plate to their rotary axis.
A: Yes. The full plate is fully customisable: we can add 4/6/12/16 stations, change slot profiles to match your existing zero-point chucks, rename part numbers, or add custom logo laser marking directly on the non-contact surface. All modified geometry keeps the same base tolerance and material performance.
A: Yes. Every plate ships with a full first article inspection (FAI) report including CMM measurement logs for all critical dimensions, material mill certificate, and surface finish test record if you require formal quality paperwork for aerospace / medical / ISO-registered facilities.
A: Almost always. We can match the central bore diameter, mounting bolt hole pattern, and keyway profile exactly to your existing machine interface. Just send us a photo or dimension sketch of your current rotary axis mounting flange, and we will fully match it without any adapter plates needed.
A: We offer a re-conditioning service: we can re-mill and re-finish all worn contact surfaces on your used plate, re-anodize it, and return it to brand-new tolerance performance for ~30% of the cost of a new plate. Most plates can be re-conditioned 2–3 full times over their service life.
