Frequently Asked Questions

1、What types of parts are suitable for jig boring machines?

Minnuo’s jig boring machines are perfect for precision positioning holes in fixtures, dies, aerospace parts, engine housings, precision mechanical parts, and anywhere micron-level positional accuracy is required.

2、What machining accuracy can your jig boring machines achieve?

Our jig boring machines can achieve hole diameter accuracy within ±2–3 μm, hole position accuracy within ±3–5 μm, and surface roughness up to Ra 0.2–0.4 μm, depending on setup and tooling.

3、What is the difference between a jig boring machine and a fine boring machine?

Jig boring machines emphasize positioning and geometric accuracy (hole locations relative to each other), while fine boring machines focus more on individual hole diameter and surface finish.

4、Can you recommend a model if I provide workpiece drawings?

Yes! Just send us your workpiece drawings with required hole tolerances, sizes, material type, and our engineers will recommend a suitable jig boring machine model within 10 minutes.

5、Can jig boring machines be customized for specific projects?

Absolutely. Customizations include table size, spindle speed, boring stroke, DRO/CNC systems, fixture mounting interfaces, and integration with automated measuring systems.

6、How do you ensure the positioning and machining accuracy?

Minnuo uses high-precision hardened guideways, thermal compensation systems, laser calibration, ball-bar dynamic tests, and real machining trials before delivery.

7、What is the delivery time for jig boring machines?

Standard manual jig borers are delivered in 30–40 working days. CNC or large-sized jig borers are typically delivered within 50–70 working days, depending on complexity.

8、What after-sales support do you provide?

Minnuo provides a one-year warranty, 24/7 technical support, remote video guidance, on-site installation assistance, and long-term spare parts availability for 10+ years.
