Product Introduction

Product Description

Large workpieces need room to move, but they also need a machine that stays steady when the cutting gets heavy. This CNC gantry milling and boring machine is built for exactly that kind of job. With a wide gantry structure, long X/Y-axis travel, adjustable Z and W axes, and a large working table, it is designed for machining oversized metal components that would be difficult to handle on a conventional machining center.

The JGM series includes JGM2560T, JGM3080T, JGM40100L, JGM50120L, JGM50120D, and JGM60160D models. The working range extends from 6,500 × 4,300 mm to 16,500 × 7,800 mm, while optional worktables can support loads of up to 25 t/m². Depending on the configuration, the spindle uses a 500 × 500 mm or 600 × 600 mm ram section, with spindle speeds up to 2,000 rpm and maximum spindle torque reaching 10,000 Nm.

This CNC gantry milling and boring machine is a practical choice for heavy machinery, shipbuilding, energy equipment, mining machinery, large molds, steel structures, and other industries where machining size and cutting stability are key concerns.

Product Features

01/

Large Gantry Structure for Oversized Parts

The biggest advantage is the available machining space. X-axis travel ranges from 6,500 to 16,500 mm, while Y-axis travel reaches up to 7,800 mm. The gantry opening can reach 7,500 mm on the JGM60160D, giving operators plenty of room for large components.

The spindle-to-table distance can also be configured for different workpiece heights, making the machine suitable for a wide range of large-part machining jobs.

02/

Powerful Spindle for Milling and Boring

The spindle speed range is 10–2,000 rpm. JGM2560T, JGM3080T, JGM40100L, JGM50120L, and JGM50120D models use a 58 kW main motor, while the JGM60160D is equipped with an 81 kW motor and up to 10,000 Nm of spindle torque.

This gives the machine enough cutting power for demanding milling and boring operations while still allowing more flexible speed selection for different materials and tools.

03/

Rigid Structure and Guideway Options

The gantry, crossbeam, ram, and other major structural components are designed around a heavy-duty construction to reduce vibration during large-part machining. Precision-machined guide surfaces help maintain stable movement over long travel distances.

The machine can be configured with linear guides, while hardened guideways are available for selected Z-axis configurations. The larger models use hydrostatic guideways to support smooth movement and stable positioning under heavy loads.

Exact material grades for castings, structural components, and guideway parts can be specified according to the final machine configuration and machining requirements.

04/

Flexible Tool Heads and CNC Systems

Different attachment heads can be selected depending on the job, including vertical milling heads, universal milling heads, extended milling heads, flat heads, and other customized heads.

The machine can use FANUC 0i or Siemens 828D CNC systems, with FANUC 31i and Siemens ONE available as optional upgrades. Standard tool capacity is 40 tools, with 60, 80, or 100-tool options available.
