Industrial-grade machining systems, precision line boring equipment, and heavy-duty repair infrastructure — built to deliver exact results on the most demanding engineering projects in Nigeria.
Our Engineering Infrastructure
Our workshop is equipped with precision machining systems, advanced line boring equipment, and heavy-duty repair tools specifically selected to handle complex industrial and automotive engineering projects. Every piece of equipment is maintained to operating specification and calibrated to consistent performance standards.
We combine skilled engineering expertise with reliable, purpose-built machinery. This combination is what allows us to guarantee consistent, high-quality results — whether we are restoring a single excavator bore on a construction site or overhauling an industrial diesel engine in our workshop.
What We Operate
Four integrated equipment categories that collectively enable AutoBore Pro to handle the full range of precision engineering, heavy equipment repair, and mechanical restoration work we undertake.
Our line boring systems are the backbone of AutoBore Pro's industrial capability. Designed to restore worn pivot points, bearing housings, and structural bores on heavy equipment — in the workshop or at a client's site — these systems deliver the precision that heavy industrial applications demand. This is our primary differentiator in the Nigerian market.
Fully portable rigs with self-aligning boring bars that set up directly on the equipment being repaired. Eliminates the need for machinery removal — the boring rig comes to the machine. Bore range: 40mm to 600mm diameter.
Laser and mechanical alignment tools used to verify bore axis alignment before, during, and after boring operations. Ensures completed bores meet OEM centreline specifications to within ±0.01mm.
Tungsten carbide-tipped boring tools with micrometer adjustment for precise cutting diameter control. Multiple bar configurations for different bore diameters, depths, and access constraints.
Hydraulic press tooling for precision-fit bushing installation in restored bores. Ensures interference fits are applied to correct tolerances and bushings are installed square and concentric with the bore axis.
Digital and mechanical bore gauges, vernier calipers, and inside micrometers used to measure bore dimensions to 0.001mm resolution at all stages of the boring process.
MIG and arc welding equipment used for bore build-up where excessive wear has reduced material beyond the boring minimum. Welded surfaces are then machined back to specification in a controlled, single-pass operation.
Workshop-based precision machining for component restoration, shaft repair, and reconditioning. These machines allow us to bring worn or damaged components back to engineering specification — or to machine new components from raw material where replacement is not available or cost-effective.
Heavy-duty engine lathes for shaft turning, journal restoration, facing, and threading operations. Swing capacity to 800mm diameter. Used for crankshaft journal preparation, pin machining, and custom component manufacture.
Precision milling for surface machining, keyway cutting, slot milling, and component profiling. Used for cylinder head surface restoration, bearing cap machining, and housing preparation before line boring.
Dedicated crankshaft grinding machine for main bearing and crankpin journal restoration. Achieves Ra 0.4µm surface finish and journal roundness within 0.005mm. Handles crankshafts from small petrol engines through to large industrial diesel units.
Valve seat cutting machine, valve guide reaming tools, pressure testing equipment, and surface grinder. Allows full cylinder head reconditioning including seat inserts, resurfacing, and pressure integrity verification.
Engine block cylinder boring machines for oversize piston preparation, followed by precision honing to achieve correct bore geometry, roundness, and cross-hatch pattern for piston ring seating.
Precision surface grinder for flat surface restoration on cylinder heads, engine block decks, and mating flanges. Achieves flatness tolerances within 0.02mm across surfaces up to 600mm × 300mm.
The infrastructure required for large-scale mechanical repair, structural welding, and component fabrication. This equipment category supports our heavy equipment repair capability — allowing us to work on mining machinery, marine components, and large commercial vehicles that smaller workshops cannot accommodate.
Industrial hydraulic presses for bushing installation and removal, bearing press-fit operations, straightening of shafts and structural components, and force-fit assembly operations under controlled load.
Heavy-duty MIG welders for structural repair and fabrication, TIG welders for precision work on alloy components and thin sections, and arc welding for high-deposit structural work on steel frames and housings.
Specialized welding equipment and consumables for applying hard-facing overlays to wear surfaces — bucket cutting edges, crusher jaws, and wear plates — significantly extending component service life in abrasive environments.
Workshop overhead crane with 5-tonne capacity for safe handling of heavy engine blocks, transmission assemblies, excavator components, and large fabrication workpieces during all stages of assembly and repair.
Plasma cutting and oxy-acetylene cutting sets for structural steel cutting, plate profiling, and pipe section work. Angle grinders, chop saws, and bench grinders for component preparation and finishing.
Rotating engine stands for safe full-orientation access during engine assembly and disassembly. Transmission repair fixtures and specialized holding devices for component overhaul work.
Every repair completed by AutoBore Pro is verified before it leaves our care. Our inspection and testing equipment allows us to confirm that dimensions are correct, surfaces meet specification, systems hold pressure, and electrical circuits operate within parameters. No work is signed off without documented measurement records.
Bore gauges, inside and outside micrometers, vernier calipers, dial test indicators, and surface roughness testers. All instruments calibrated to NIST-traceable standards for measurement confidence.
Hydraulic pressure test kits for cylinder head and engine block leak-down testing after reconditioning. Identifies porosity, cracks, or seal failures before assembly — preventing premature engine failure on rebuilt units.
Multimeters, insulation testers, battery load testers, and alternator output test equipment for vehicle electrical system inspection, diagnosis, and post-repair verification on all automotive electrical work.
Compression testers, oil pressure gauges, vacuum test equipment, and cylinder leak-down testers for systematic mechanical fault diagnosis on engines and transmission systems prior to and following repair work.
Magnification equipment, bore scopes for internal inspection of cylinders and bores, dye penetrant kits for surface crack detection, and straight-edge sets for flatness verification on machined surfaces.
Portable laser alignment tools for post-repair shaft, bore, and coupling alignment verification. Provides objective measurement data that is recorded and provided to clients as part of the job completion documentation.
Structured Methodology
Precision engineering is not just about the machine — it is about the methodology. Every job we undertake follows the same disciplined process, regardless of scale.
Full mechanical inspection before any work begins. Dimensions recorded, fault root cause identified, and equipment condition documented. No guesswork at this stage.
All machining tolerances defined against OEM specifications. Boring bar alignment verified to centreline before cutting begins. Nothing proceeds until alignment is confirmed within spec.
All cuts made in controlled passes with measured feed rates and depths. Tooling condition checked between passes. Final dimension approached in light finishing cuts to prevent oversize.
Post-machining dimensions measured and recorded. Surface finish verified. Functional testing where applicable. Job is not signed off until measurements confirm the specification has been met.
Equipment returned to service with documented measurement records, specification confirmation, and maintenance recommendations. Client receives full job report with all post-repair data.
Our Workshop
Our workshop is not a roadside garage — it is a structured industrial engineering facility designed to safely handle heavy components, maintain precision standards, and execute complex multi-stage repair operations efficiently. The layout is organised around logical workflow zones to prevent cross-contamination between precision machining and heavy fabrication activities.
Climate-managed zone housing lathes, mills, and grinding machines. Maintained to consistent temperature for dimensional stability during precision work.
High-clearance service area with overhead crane access for heavy component handling. Designed to accommodate large excavator components, truck chassis, and industrial machinery.
Dedicated welding area with proper fume extraction, fire suppression, and segregation from the precision machining zone. Minimises contamination risk to machined surfaces.
Clean, dedicated area with full measurement equipment for post-repair inspection. All completed work is verified and documented before release to the client.
Defined pedestrian walkways, marked load-bearing zones, fire suppression systems, and PPE stations throughout. All work follows documented safe work procedures.
The Business Case
The quality and capability of our machinery directly translates into measurable business outcomes for the companies that work with us. Industrial-grade equipment is not an overhead — it is the foundation that allows us to make guarantees that matter to your operations team.
Industrial-grade tooling restores components to OEM specification — not close to it. When bores and machined surfaces meet exact tolerances, the repaired component performs as designed and does not require re-servicing prematurely.
Mobile on-site equipment deployment eliminates the need to remove heavy machinery from site for workshop repair. What would otherwise take 5–10 days of transport, repair, and return is completed in hours at the machine's location.
Precision restoration brings worn components back to original specification — extending the operational lifespan of the equipment by years rather than months. This directly defers capital expenditure on machine replacement.
Equipment repaired to specification performs predictably within its designed load and wear parameters. Clients experience significantly lower unplanned breakdown frequency after precision restoration compared to approximate repair methods.
Precision repair consistently costs less over a 3–5 year horizon than repeated approximate repairs or component replacement. Our equipment capability allows us to offer restoration options that extend asset life at a fraction of new-equipment cost.
Every job leaves with a documented measurement record. This supports equipment warranties, insurance claims, regulatory compliance, and resale value — providing clients with traceable evidence of the work performed and the standards achieved.
Our Standards
The tolerances in this table represent the standards we apply to every job — not aspirational figures. Our equipment is capable of achieving these results consistently, and our measurement instruments allow us to verify and document that they have been achieved before any work leaves our facility.
These are the same standards applied on small commercial vehicles and on major industrial machinery. Precision does not change with the size of the job.
Measuring instruments maintained in calibration with documented calibration records. Measurements are traceable and reliable.
All machining tolerances referenced against OEM service data where available. Client's equipment is restored to manufacturer-specified parameters.
Pre-repair and post-repair measurements recorded and provided to clients with every completed job. Permanent evidence of the work performed.
We do not estimate dimensions or assume sizes. Every bore is measured before cutting begins and after cutting is complete. This is non-negotiable.
