FAQs
What precision engineering services do you provide for electrical generators in Winchester?
We offer a full suite of precision engineering solutions tailored to electrical generators, including CNC milling and turning, dynamic balancing, shaft and rotor machining, housing re-boring, reverse engineering of obsolete parts, and performance-enhancing upgrades. All services are carried out in our Winchester facility, allowing tight control over quality, turnaround, and logistics.
Can you design and manufacture custom generator components?
Yes. Our in-house design team works with 3-D CAD/CAM software to create bespoke parts such as end shields, slip-ring assemblies, couplings, and cooling fans. After design approval, components are produced on multi-axis CNC machines capable of tolerances down to ±5 µm. We can also source and certify specialised materials (e.g., stainless, Inconel, copper alloys) to match electrical and mechanical requirements.
Do you offer on-site generator repair and maintenance?
Absolutely. Our mobile engineering crews cover Winchester and the surrounding Hampshire area 24/7. Services include vibration analysis, bearing replacement, laser alignment, stator rewinds in partnership with our electrical division, and load testing. Emergency call-outs are usually attended within 2 hours, minimising downtime for critical power systems.
What quality standards and certifications do your generator parts comply with?
Our workshop operates under an ISO 9001:2015 quality management system and follows BS EN 60034 guidelines for rotating electrical machines. All critical components receive full dimensional inspection reports, certificate of conformity, and material traceability (EN 10204 3.1). For clients in regulated sectors, we can also provide PPAP, FAI, or NDT documentation upon request.
What is the typical lead time for a precision-machined generator component?
Standard lead times range from 5 to 10 working days, depending on complexity and material availability. For urgent repairs we offer an expedited 24- to 48-hour service, utilising reserved machine capacity and local material stockholders. Large-scale production runs may require 2 to 4 weeks; however, we can stage-deliver parts to keep your project on schedule.
How can I obtain a quotation or technical consultation?
Email your drawings, sketches, or sample photos to [email protected], or call our engineering desk on 01962 555 240. If you are unsure of specifications, our engineers can visit your site to take measurements and discuss operating conditions. Quotes are typically returned within 24 hours and include price, lead time, material grade, and recommended surface finish or treatments.
