Minnuo’s floor boring machines are ideal for large, heavy workpieces such as turbine casings, wind tower bases, marine engine blocks, large gearbox housings, and heavy-duty machine frames.
A typical floor boring machine consists of a moving column (or ram), stationary worktable or floor plates, high-rigidity bed structure, and often multiple milling and boring heads for multi-side machining.
Our floor borers can achieve positioning accuracy within ±0.01–0.02 mm and repeatability within ±0.008 mm, with surface roughness reaching Ra 0.8–1.6 μm, depending on the cutting system and tooling.
Absolutely! Just send us your workpiece size, weight, required machining areas, and material information, and we’ll recommend the appropriate floor boring machine model within 10 minutes.
Yes! We offer customizations like column travel length, spindle diameter and power, worktable size, automatic tool changers (ATC), rotary tables, and integration with automation lines.
Minnuo uses high-grade Meehanite casting, servo drive systems, hydrostatic guideways (optional), laser calibration, and full trial cutting tests to guarantee top machining precision and stability.
Standard models are delivered within 90–120 working days. Fully customized large floor borers may require 120–180 working days depending on specifications.
Minnuo provides a one-year warranty, 24/7 technical support, online setup training, remote troubleshooting, on-site services, and long-term spare parts support (10+ years).
