All questions
What does JEP Manufacturing do?
We are a precision CNC machine shop in Houston, Texas. Our core work is 5-axis machining of turbomachinery components: blisks, blings, inducers, impellers and turbine blades. We also offer 9-axis mill-turn machining and large parts up to 82 in long.
Do you work with customers outside Texas?
Yes. We quote and ship to customers across the United States. Most RFQs come in by email or through our website with STEP and PDF files.
How do I get a quote?
Use the Request a Quote page or email your STEP model and PDF drawing to info@jepmfg.com. We reply within one to two business days.
Does every quote include a lead time?
Yes. Every quote states a lead time, based on current shop load and material availability. Ask if you need a faster date, and we'll tell you honestly whether it's possible.
What file formats do you accept?
STEP, IGES, SolidWorks, DXF and PDF. STEP is preferred for 3D work.
What is the largest part you can machine?
82 in long. Turning to Ø26 in, 5-axis milling to Ø31.5 in × 43.5 in, and 3-axis milling with 60.2 in of X travel.
What tolerances can you hold?
±0.005 in standard, ±0.001 in on critical features, and as tight as ±0.0002 in where the feature and material allow it.
Are you ISO 9001 or AS9100 certified?
Our quality system is compliant with ISO 9001:2015 and AS9100D. Third-party certification is planned. We include FAI on new parts, heat-lot material traceability and a certificate of conformance with every shipment.
Do you machine Inconel and titanium?
Yes. Inconel 718 and 625 and titanium Grade 2 and Grade 5 (Ti-6Al-4V) are regular materials in our shop.
Can you use customer-supplied material?
Yes. Customer-supplied material is logged on receipt, tracked by heat lot and kept separate.
Do you do welding?
Yes. We TIG weld in-house and machine welded parts after welding, so welding and machining run as one job. Typical work is carbon steel reducers, elbows, pipeline fittings, fabricated housings, repair and build-up.
Can you handle export-controlled (ITAR) drawings?
Yes. We are ITAR compliant. Tell us before sending, and don't upload controlled data through the web form; we'll arrange a secure transfer.
Are you registered for government work?
Yes. We are a SAM.gov-registered small business, CAGE 9ZYL5, UEI HASJYZLT23C9, primary NAICS 332710.
Have a print or a STEP model?
Send it over. We review every RFQ by hand and include a lead time with every quote.
