What Are Custom Automation Equipment Parts?
Custom automation equipment parts are the non-standard, made-to-drawing components that make up a piece of automation machinery — a robot cell, an assembly line, a pick-and-place station, a test rig, or an inspection fixture. They are not catalogue items. Every machine a builder designs needs its own brackets, housings, shafts, plates, pins, and fixtures, machined to fit that specific layout, motion path, and payload.
Because each automation project is essentially one-of-a-kind, the parts list is dominated by low-to-mid-volume, high-mix components: a handful of each part number, dozens of part numbers per machine, often with tight tolerances on the features that locate, guide, or mount moving elements. This is exactly the work that doesn't fit an instant-quote platform optimized for single high-volume parts — and exactly the work Richconn is built for.
Typical reasons machine builders outsource automation parts to Richconn:
- Free up in-house machines for assembly and debugging by outsourcing the part-making
- Get a full machine's worth of mixed parts from one supplier, kitted to the BOM
- Hold tight tolerances on locating and motion features that conventional shops miss as an assembly
- Move a validated machine into repeat builds with stable, traceable batch production
- Reduce unit cost on a China-based precision partner while keeping ISO-certified quality

Automation Components We Machine
Under the housing, an automation machine is an assembly of individually machined parts. Below are the components that recur in almost every build — with the machining requirement that actually drives quality on each one.
Joint & Bearing Housings
Bearing bore ±0.01 mm · 4/5-axisThe structural shell that encloses bearings, gears, and motor at each axis of rotation. It carries the full load path between links, so it must be stiff and precisely bored. Usually machined from 6061-T6 or 7075-T6 aluminum to keep weight down.
Bearing bores held to ±0.01 mm for correct preload and alignment. Bores, mounting faces, and cable-routing features sit on multiple sides — so these almost always need 4- or 5-axis milling to avoid multi-setup positional error.
Gearbox & Reducer Casings
Bore Ra 0.8 μm · Concentric to μmCasings for harmonic or cycloidal reducers must maintain precise alignment between input and output shafts while carrying torque and gear-mesh reaction loads. Custom casings are needed even when the reducer itself is off-the-shelf, because it must integrate with a specific motor, encoder, and joint.
The bore seating the wave generator / eccentric cam needs surface finish below Ra 0.8 μm and concentricity within a few microns of the output bearing bore — or the gearbox runs rough and wears early.
Motor-Mount Plates & Flanges
Pilot bore GD&T ◎ 0.02 mmConnects the servo motor to the gearbox and joint structure. Looks simple — a plate with a bolt pattern and a central bore — but its tolerances decide whether the motor shaft aligns with the gearbox input. Misalignment of a few hundredths of a millimeter creates vibration the controller must compensate for, limiting cycle time.
Concentricity of the pilot bore relative to the bolt pattern, called out with GD&T position tolerance of 0.02 mm or less. Fixture alignment matters as much as the dimensions — we fixture for assembly position, not just feature-by-feature.
End-Effector / Tool Flanges
ISO 9409-1 · ⊥ 0.01–0.02 mmThe plate at the end of the arm where grippers, dispensing heads, welding torches, and other tools attach. Most industrial robots follow an ISO 9409-1 standard flange pattern. This plate is the datum for everything the robot does — get it wrong and the tool-center-point shifts on every rotation.
Flatness and perpendicularity of the flange face, typically within 0.01–0.02 mm of the last axis of rotation, plus a precise locating feature so end-of-arm tooling repeats position across changeovers.
Guide Shafts, Cams & Linear Parts
Concentricity · Hardened wear facesGuide shafts, lead-screw supports, cam followers, indexing cams, eccentrics, linkages, and slider blocks — the parts that define and constrain motion. Often turned then ground, or milled then heat-treated, with wear-critical surfaces specified for hardness and finish.
Straightness and concentricity on guide shafts; profile accuracy on cams; hardened, low-Ra wear faces. We turn, mill, heat-treat, and grind in a controlled process route so motion stays smooth over machine life.
Locating Pins, Blocks & Manifolds
Dowel fit H7 · Cross-drilled portsDowel pins, locating pins, V-blocks, stop blocks, and pneumatic manifolds (sub-plates with multiple cross-drilled air passages). These set the repeatable datum of the whole machine and route the air that drives its actuators.
Precise dowel / locating fits (H7 class) that set repeatable positioning accuracy; clean, burr-free intersecting bores on manifolds so air paths seal without leaks. Deburring here is a quality step, not an afterthought.

The Capacity Behind Your Parts
Automation parts are high-mix and time-sensitive. Richconn backs this page with a dedicated precision machining base running two shifts, so a full machine's worth of mixed part numbers moves without queueing behind a single big job.
3 / 4 / 5-Axis Machining Centers
From flat plates and brackets to compound-geometry housings and flanges in a single setup — the right axis count matched to the part, not forced onto the machine.
CNC Turning & Mill-Turn
Guide shafts, pins, bushings, and shaft-with-feature parts — turned, cross-drilled, and milled with imported lathe capacity for stable concentricity.
Gantry Machining Centers
Large base plates, frames, and structural fixtures for full automation cells — handled on gantry-type centers without splitting the part.
Two-Shift Mid-Volume Output
Two shifts of 10 hours keep mixed-part schedules moving. Average monthly output of 50,000–80,000 parts depending on complexity, with sample lead time of 3–5 working days.
CMM + Optical + 4-Gate QC
Every part passes at least three independent inspection gates — IQC, IPQC, FA, OQC. CMM, 2D optical projector, and height gauges verify critical features. Records retained 3 years and fully traceable.
Deburr · Finish · Assemble · Kit
All parts cleaned, deburred, and rust-protected before shipment. Optional sub-assembly and kitting per machine BOM so a builder receives ready-to-assemble component sets, not loose parts.
Materials & Finishes for Automation Parts
Material choice on automation parts is driven by weight, wear, corrosion, and electrical needs. Below are the grades and finishes we run most often, matched to where they fit on a machine.
| Material | Common Grades | Where It Fits on the Machine |
|---|---|---|
| Aluminum | 6061-T6 · 7075-T6 · 6082 | Joint housings, brackets, motor mounts, base plates, flanges — light, stiff, fast to machine |
| Stainless Steel | 303 · 304 · 316 · 17-4PH | Guide shafts, pins, food/clean-line parts, corrosion-resistant fittings |
| Tool Steel | D2 · SKD11 · H13 · A2 | Cams, wear plates, hardened locating pins, fixture inserts (heat-treated) |
| Brass / Copper | C360 · H62 · C110 | Bushings, electrical contacts, busbars, conductive parts |
| Titanium | Grade 5 (Ti-6Al-4V) | Lightweight high-strength arm parts where mass matters most |
| Engineering Plastics | POM · PEEK · PTFE · Nylon | Wear pads, low-friction guides, insulating parts, product-contact nests |
| Finish | Typical On | Purpose |
|---|---|---|
| Type II Anodize | Aluminum housings, plates | Corrosion resistance + color coding of machine zones |
| Type III Hardcoat | Aluminum wear surfaces | Hard, wear-resistant oxide for sliding / contact faces |
| Black Oxide | Steel pins, fixtures | Mild corrosion resistance, low-glare finish |
| Passivation | Stainless parts | Restores corrosion resistance per ASTM A967 |
| Heat Treatment | Tool steel, 17-4PH | Hardness HRC 40–62 on cams, pins, wear plates |
| Bead Blast / Laser Mark | Most metals | Uniform cosmetic finish; permanent part / batch ID |

Why Machine Builders Source Automation Parts From Us
Built for High-Mix, Not Just High-Volume
A machine build is dozens of part numbers, a few of each. Instant-quote platforms are tuned for one big part; we're set up to take a full BOM of mixed components and run them together — quoted, machined, inspected, and kitted as one job.
We Fixture for the Assembly, Not Just the Part
Many shops produce parts that pass individual dimension checks but are out of position as an assembly. On flanges and mount plates we fixture for true assembly position and verify the relationship between features — so parts fit the first time at your build station.
Tight Tolerance on the Features That Matter
Bearing bores to ±0.01 mm, pilot bores with GD&T position of 0.02 mm, flange faces flat and perpendicular within 0.01–0.02 mm. We hold tolerance where motion and location depend on it — and don't inflate cost by over-toleranceing the rest.
No Blind Pursuit of 5-Axis
If a 3-axis machine can do the job well, we don't add unnecessary cost. Smart toolpaths and stable fixtures beat simply buying more expensive machine time. You pay for the part the design needs, not for machine-class prestige.
Two-Shift Capacity, 3–5 Day Samples
Two shifts and 50,000–80,000 parts/month of throughput mean your mixed parts don't queue behind a single big job. Samples in 3–5 working days, batch in 7–15 — fast enough to keep a machine build on schedule.
4-Gate Inspection, 3-Year Records
Every part clears at least three independent inspection gates (IQC, IPQC, FA, OQC) under an ISO 9001:2015 system, with CMM and optical verification. Inspection records are kept 3 years and fully traceable — the documentation serial-machine programs need.
Four Independent Inspection Gates
Quality is not inspected into a part — but inspection is the last line of defense. Every automation part runs through a documented four-gate flow from incoming material to outgoing shipment.
Incoming Quality Control
Raw stock verified against mill certificate before any cutting begins. Wrong material never enters the floor.
In-Process Quality Control
Operators gauge critical features at set intervals during the run. Drift is caught mid-lot, not at the end.
First-Article Inspection
First piece off every new setup fully checked on CMM and optical against the drawing before the lot proceeds.
Outgoing Quality Control
Final dimensional + cosmetic check, deburr and clean confirmed, inspection record packed with the shipment.
Richconn holds ISO 9001:2015 and inspects with CMM, 2D optical projectors, and standard metrology. We state the tolerances and finishes we can hold in series production with documented records — and if a drawing calls for tighter than our standard process holds, we'll tell you up front whether grinding, specialty inspection, or an alternative route is required.
