1. Product Overview

If you are looking for a heavy-duty, long-service-life, ultra-precision gantry surface grinder for large mold bases, steel plates, casting frames, mechanical structural parts, our Fixed Beam Single-Head Gantry Grinding Machine is your ideal manufacturing partner.

This CNC gantry grinder adopts fixed triangular beam closed frame structure, specially designed for heavy load & large-size workpiece flat grinding. Equipped with Yonghong PLC+HMI two-axis servo control system, it realizes stable automatic grinding with micron-level precision, widely adopted in mold manufacturing, automotive parts, heavy machinery, aerospace, steel processing industries worldwide.

2. Core Competitive Advantages (7 Unique Strengths)

1 High-Rigidity Triangular Crossbeam Structure

Triangular integrated beam greatly boosts bending & torsion resistance. The grinding head is tightly locked on beam without vibration during grinding. No wheel jumping or rapid dulling, effectively lift grinding efficiency and long-term precision stability, solving the precision drifting problem of ordinary gantry grinders under heavy cutting.

2 Taiwan Imported PTFE Laminated Guideways + Full Dustproof Cover

All guide rails go through precision grinding + manual scraping process, covered with Taiwan Teflon soft strips. Low friction coefficient, energy saving, smoother running and lower power consumption. Full-enclosed dust shield fully isolates grinding dust & coolant from guide rails, avoid corrosion and abrasion, extend machine service life by 30%+.

3 Precision Ball Screw Transmission with Self-Locking

X/Y/Z three axes use high-precision ball screw + refined gearbox transmission, featuring high transmission efficiency, accurate positioning and self-locking function. Supporting electronic handwheel for manual fine feeding; Z-axis minimum feed reaches 0.005mm, easy for ultra-fine finishing.

4 Ultra-Precision Custom Spindle Assembly

Flange spindle adopts ultra-precision angular contact ball bearings for outstanding grinding rigidity. Spindle & motor are customized by Taiwan professional factory, Japan imported coupling. After strict dynamic balance calibration, vibration level reaches V3 standard, spindle runout controlled within 0.003mm, guarantee mirror-level grinding finish.

5 Intelligent Intermittent Circulating Lubrication System

Independent circulating oil supply for beam & vertical guideways, automatic timed oiling. Realize full-range sufficient lubrication without oil waste or workpiece oil pollution, protect guide rails & screws to maintain consistent long-term accuracy.

6 Simple Humanized CNC Operation Panel

Integrated Yonghong PLC touchscreen control, common grinding functions set as shortcut buttons, no complicated professional programming required. Novice operators can master operation within 1 hour. Matched with electronic handwheel for quick alignment & fine adjustment, lower labor training cost for your factory.

7 Heavy-Duty Heat-Treated Machine Body

Bed base, crossbeam and sliding blocks adopt high-frequency quenching treatment for high hardness and wear resistance. Worktable & cross slide lined with PTFE material, support max 5000kg heavy workpiece loading without deformation.
