Jiri Lee Operations Director

Guan Mei has been our go-to CNC machining partner for over 5 years. Their precision parts and quick turnaround times have consistently exceeded our expectations. They truly understand the automotive industry’s needs.

Ventas Procurement specialist

We've been able to streamline our production process with Guan Mei’s high-quality automotive parts. The consistency and attention to detail they provide are unmatched."

Jane Smith R&D Lead

I’ve been a mechanical engineer in the automotive parts industry for over a decade, and GM-PRE CNC’s machines have truly raised the bar for us. The precision on their CNC routers is unmatched—we’re seeing tolerances consistently under 0.001 inches, which has cut down our rework by 30%. Their technical team is also incredibly responsive, which makes a huge difference when we’re on tight production deadlines. Highly recommend!

John Smith Senior Mechanical Engineer

As a production manager at a mid-sized aerospace subcontractor, reliability is everything. GM-PRE CNC’s machining centers have been workhorses for us, and the software integration with our existing systems was seamless. What stands out, though, is their after-sales support. When we had a minor calibration issue last quarter, their technician was solute within 24 hours, no extra charges. It’s clear they care about their clients’ success

Maria Garcia Production Manager

Running a small custom metal fabrication shop, we need equipment that’s both precise and user-friendly. GM-PRE CNC delivered on both. Their entry-level milling machine was easy to set up, even for our team with limited CNC experience, and the finish on the parts it produces is consistently smooth. They worked with us on a payment plan that fit our budget. Three years in, it’s still our most reliable piece of equipment.

Lisa Wong Operator

In medical device manufacturing, there’s zero room for error. GM-PRE CNC’s turning centers are the backbone of our production line for surgical instrument components. The repeatability is spot-on—we’ve run thousands of identical parts, and the variance is negligible

David Chen Quality Assurance Lead

We specialize in prototyping for industrial machinery, so we need CNC machines that can handle quick changeovers and complex geometries. GM-PRE’s 5-axis machining center has been a game-changer. It cuts setup time in half compared to our old equipment, and the accuracy on intricate parts—like the gear housings we prototype—has impressed even our pickiest clients. Their sales rep also took the time to understand our specific needs, recommending the exact model that fit our workflow, not just the most expensive one
