NMX-SBP-30 · ENGINEERED TO ORDER — SHOT BLASTING & PEENING SYSTEMS

Blast it clean. Peen it to last.

Name: Shot Blasting & Peening System
Brand: Neometrix

Two jobs from one abrasive stream. A shot-blasting system that cleans, descales and profiles a surface to a standard before painting or coating — and a shot-peening system that bombards a part with controlled shot to build a compressive-stress layer and extend its fatigue life. Airless wheel or air-blast, in a room, a cabinet or an automated cell. We build the room, the abrasive recovery, the dust collection, the handling and the controls; the blast wheels, media and dust cartridges are bought in. Engineered to order — no specific delivered system is claimed.

Overview

One abrasive stream, two opposite jobs.

Throw hard abrasive at a steel surface fast enough and one of two useful things happens. Aim to remove material and you strip off rust, scale and old paint and cut a clean profile for the next coating — surface preparation. Aim to add a stressed skin instead of removing metal, using round shot at a controlled intensity, and you build a compressive residual stress layer that dramatically extends a part’s fatigue life — shot peening. Same core technology; opposite intent.

The blast is the easy part. Propelling abrasive — by airless throw-wheels or compressed-air nozzles — is straightforward. The engineering is the system around it: recovering the reusable media from the dust and broken grit and recirculating it, containing the dust, and moving the parts through. Get the recovery wrong and a blast machine chokes on its own spent abrasive.

Surface prep is to a standard. Cleaning is not ‘looks clean’ — it is a graded Sa 2.5 to Sa 3 (ISO 8501 / SSPC) with a defined profile, because the profile is what a coating keys into. A blast system for surface prep has to deliver that standard repeatably across the whole part.

Peening is a metallurgical process. Shot peening is controlled, not cleaning: the intensity (measured with Almen strips as arc-height) and the coverage are specified and verified, because it is the compressive stress it induces — on gears, springs, shafts, landing gear and turbine parts — that buys the fatigue life. It draws on the same fatigue understanding as our servo-hydraulic fatigue machine.

A blast wheel and a nozzle are commodities. What makes a shot-blasting or peening system is the abrasive recovery, the dust containment, the handling and, for peening, the Almen-controlled process — and that is the engineering, not the blast.

Two Jobs, One Stream

Clean it off, or harden it

Surface preparation removes rust, scale and paint and cuts a profile to a standard; shot peening adds a compressive-stress skin to extend fatigue life. Opposite intents, one core technology — both on this page.

The System Is the Recovery

Not just the blast wheel

The engineering is the abrasive recovery & reclaim, the dust collection, the material handling and the automation — the parts that turn a blast wheel into a working, clean, repeatable system. The blast itself is the easy part.

Peening Is Controlled

Almen-verified, for fatigue life

Shot peening is a metallurgical process — intensity (Almen arc-height) and coverage specified and verified — because the compressive stress it induces is what extends fatigue life on gears, springs, landing gear and turbine parts. It cross-links our fatigue-test machine.

Architecture

Blast, recover, finish.

The schematic shows the blast loop — part, blast, spent media, recovery and reclaim — and the two things the system then does: prepare a surface to a standard, or peen a part to extend its life. The detail panel covers the forms and the standards.

The Blast

Airless throw-wheels for high-throughput surface prep, or compressed-air nozzles for reach, detail and peening. The abrasive and its velocity are chosen to the job — clean, profile or peen.

Arc · 02

Abrasive Recovery & Reclaim

The heart of the system: a bucket elevator and an air-wash separator / classifier that split the reusable media from the dust and broken abrasive and recirculate the good media. Get this right and the machine runs; get it wrong and it clogs.

Arc · 03

Dust Collection & Containment

A cartridge or baghouse dust collector and ventilation that contain the fine dust the process creates — keeping the enclosure clear and the workplace safe and compliant.

Arc · 04

Material Handling & Automation

Conveyors, monorails, turntables, spinner-hangers and, where needed, robotic / CNC manipulation of the head or the part — so the finish is even and repeatable across the whole component.

Where a blast system goes wrong

In the recovery, the dust and the control — rarely the blast. Undersized recovery and the machine chokes on spent abrasive; a weak dust collector blinds the operator and fails a safety audit; uneven handling leaves patches under-blasted; and for peening, an uncontrolled intensity or coverage either does nothing or does harm.

That is why the recovery is sized to the abrasive flow, the dust and containment are engineered in, the handling presents every surface, and peening is Almen-controlled and coverage-verified. The system is only worth the standard it can hold, part after part.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 What is the difference between shot blasting and shot peening?

They use the same idea — propelling abrasive at a surface — for opposite purposes. Shot blasting (and grit blasting) is about removing material: it strips rust, mill scale, old paint and casting residue off a surface and cuts a controlled profile, so that the surface is clean and keyed for the next coating. It typically uses angular grit (or coarse shot) at high velocity, and success is measured against a cleanliness standard like Sa 2.5–3 plus a profile. Shot peening is about adding something, not removing it: it bombards the surface with round shot at a carefully controlled intensity so that each impact plastically stretches the surface a little, leaving a thin layer of compressive residual stress. Because fatigue cracks start at the surface under tension, putting the surface into compression dramatically extends the fatigue life and resists stress-corrosion cracking — which is why it is used on gears, springs, shafts, landing gear and turbine blades. So: blasting cleans and profiles, peening strengthens against fatigue. Same machine family, very different process control — and this page covers both.

Q · 02 What actually is the “system” — isn’t it just a blast wheel?

The blast wheel or the blast nozzle is the part everyone pictures, but it is the commodity in a blast system, not the engineering. The engineering — and where a system succeeds or fails — is everything around it. First, abrasive recovery and reclaim: a blast machine reuses its abrasive many times, so it needs a bucket elevator to lift the spent mix and an air-wash separator to split the good, reusable media from the dust, the broken-down fines and the debris, and return only clean media to the wheels — get this wrong and the machine chokes, wears out fast or blasts with junk. Second, dust collection and containment: blasting generates a great deal of fine dust that has to be captured by a cartridge or baghouse collector and vented, for visibility, safety and compliance. Third, material handling and automation: conveyors, monorails, turntables, spinner-hangers or robots that present every surface of the part evenly and repeatably. And fourth, the controls that tie it together. That is what Neometrix builds; the wheels, nozzles and media are bought in. A shot-blasting system is a fabrication, handling and dust-engineering problem far more than a blast-wheel problem.

Q · 03 What surface-preparation standards do you work to?

Surface preparation is specified, and delivered, to a standard — not to “it looks clean”. The most common are the ISO 8501 visual cleanliness grades and the equivalent SSPC / NACE grades, where abrasive blast cleaning is graded from Sa 1 (light) through Sa 2, Sa 2.5 (very thorough) to Sa 3 (blast-clean to bare metal). Most protective coating systems call for Sa 2.5 as a minimum. Alongside cleanliness, the surface profile (the roughness or ‘anchor pattern’ the abrasive cuts) is specified, because the coating mechanically keys into that profile — too smooth and it peels, too coarse and the peaks show through. A well-engineered blast system delivers the required cleanliness and profile repeatably across the whole part, which comes down to the right abrasive, the right energy and even coverage — the handling and the recovery again. We build the system to hit and hold the standard your coating specification demands.

Q · 04 How is shot peening controlled and verified?

Shot peening is a controlled metallurgical process, and it is worthless — even harmful — if it is not controlled, so it is verified against defined standards (typically SAE J442 and J443). Two things are controlled. First, intensity: a standard Almen test strip is peened alongside the part and its arc-height (how much it curves) is measured — that arc-height is the accepted measure of peening intensity, and the process is set so that intensity sits in the specified band, verified by a saturation curve. Second, coverage: the proportion of the surface that has actually been struck, which must reach (usually) 100% or a specified multiple, checked visually or with tracer methods. Behind those, the shot size, shape, hardness, flow rate and velocity, and the part manipulation, are all held constant. This is why a peening cell needs proper Almen fixturing, controlled media and repeatable manipulation — it is the process control, not the blast, that delivers the fatigue-life improvement, and it draws on the same fatigue understanding behind our servo-hydraulic fatigue-testing machine.

Q · 05 What forms does it come in?

The right machine depends on the part, the throughput and the job. An airless wheel-blast machine — a tumblast barrel, a spinner-hanger, or a roller-conveyor / continuous machine — uses motor-driven throw-wheels for high-throughput cleaning of castings, fabrications and stock, and is the workhorse for volume surface prep. An air-blast room is a walk-in enclosure with an abrasive-recovery floor, for large structures, fabrications and vehicles that cannot pass through a machine; an operator (or a robot) blasts inside it. A blast cabinet is the bench-scale version — a sealed box with gloves, a suction or pressure gun, its own reclaim and dust extraction — for small parts and detail work. And an automated or robotic peening cell is a controlled enclosure with robotic or CNC manipulation and Almen control, for fatigue-critical components. We size and configure whichever suits the requirement — and often a plant needs more than one — but in every case the recovery, dust, handling and controls are the substance of what we engineer.

Q · 06 What do you build, and what is bought-in?

We are clear about the split, because it is where the value is. Neometrix engineers and builds the system: the blast room, cabinet or machine enclosure; the abrasive recovery and reclaim (elevator, separator, hoppers, media handling); the dust collection and ventilation; the material handling and automation (conveyors, monorails, turntables, spinner-hangers, robotic / CNC integration); and the controls, safety and installation — which is a fabrication, mechanical-handling and integration problem, squarely our competence. What is bought-in from specialists is the blast wheels or blast nozzles, the abrasive media (steel shot and grit, ceramic, glass bead), the dust-collector cartridges, the robot arm and the Almen gauges — standard, proven components best sourced from their makers and integrated by us. That division plays to strength: the commodity blast parts come from the specialists, and the system that turns them into a working, clean, repeatable and standard-holding installation is our engineering. To be plain about status: this is offered engineered-to-order and quoted against shot-blasting and peening requirements; no specific delivered system is claimed on this page.
