The CNC gantry machining center consists of a workbench, beam, column, ATC, CNC device, and other components. The name “gantry” comes from the fact that the crossbeam and column resemble a gantry when viewed from the front. The tools take over the entire machining process through CNC and perform various operations on the workpiece. Operations include milling, drilling, threading, etc. It can machine a variety of large and complex parts, such as engine blades and wheel frames.
OTURN is a CNC gantry machining center manufacturer in China. Our CNC gantry machining center mainly includes two types: fixed column gantry machining center (gantry fixed, work table moving) and movable column gantry machining center (work table fixed, gantry moving). You are free to choose one of them. After that, we will communicate with you to determine the X, Y, Z axis travel lengths, spindle speed, number of tools, and other parameters.
The CNC gantry machining center applies a stable transmission system, stiff columns and crossbeams with advanced control systems and user user-friendly operation interface. All these ingredients are built with high-quality materials to improve the processing accuracy and efficiency.

High Precision
The highly stable three-axis guideway precisely controls the position of the tool head. A water cooling system prevents the tool head from being deformed by heat. This is why our gantry CNC machining centers offer such high precision.
High Efficiency
Our CNC gantry machining centers are capable of multi-axis machining, which can improve machining efficiency. Even complex geometries can be completely machined in a single setup.
High Rigidity
The columns and beams are equipped with reinforcing ribs, with strong rigidity and bending resistance, and are suitable for processing large-sized and heavy workpieces.
Strong Stability
The machining center’s bed, worktable, columns, beams, and other large components are made of high-density cast iron, which is very heavy and does not vibrate significantly during the processing.
High Degree of Automation
Our CNC gantry machining centers are equipped with automatic tool change, automatic measurement, automatic lubrication, and automatic chip removal. You only have to write a full program for the automatic processing.

Main Structure
The main structures, including the bed, columns, beams, and ram, are made of high-quality cast iron. These components undergo a heat treatment process to relieve residual stress. Their contact surfaces undergo a precise manual scraping process, ensuring that the entire gantry CNC machining center has high rigidity.
Workbench
The worktable utilizes two heavy-duty linear guides with low friction and high positioning accuracy. Driven by servo electrodes, it can move stably. It also has a high load capacity and excellent vibration resistance.
Drivetrain
Three guide rails use large-diameter ground-grade ball screws to form a highly rigid mechanical transmission system that drives the tool in horizontal and vertical directions. It has a compact structure, smooth movement, minimal thermal expansion, and high precision.
Automatic Tool Changing System
Our gantry CNC machining centers are equipped with automatic tool changing systems and vertical chain tool magazines so that the cutter head can be replaced quickly and accurately.
Cooling System
Our spindle adopts constant temperature cooling to improve stability and processing accuracy. Our cutting head adopts a water cooling system to reduce the temperature of the cutting head and extend its service life.
Lubrication System
We use automatic lubrication devices to regularly and quantitatively lubricate the spindle and guide rails to prevent the tool from getting stuck when it moves, which improves the reliability of the CNC machining center.
Protection System
The workbench guide adopts a telescopic protective cover, and the cross beam guide adopts an organ-type protective cover, which can protect the cleaning of precision components such as guide rails and lead screws, and improve the accuracy of the transmission of the machining center.
Operation Box
The operating box adopts an ergonomic adjustment arm. You can adjust its position freely to suit the usage habits of different operators.
Protective Cover
The CNC gantry machining center adopts a fully enclosed protective cover, which is not only beautiful and elegant but also prevents the operating environment from being contaminated by cutting fluid and oil steam, ensuring the safety and health of the operators.
Moving Parts
The moving parts adopt a lightweight design, which can quickly respond to various operating instructions. When processing complex workpieces, the direction and angle of processing can be changed at any time to improve the processing accuracy.
Motor
We use a contactless linear motor with no gaps, no wear, and no energy loss in mechanical form, which can completely convert electrical energy into power. It has a simple structure, convenient maintenance, and a long service life.
Spindle
The spindle has high rotation speed, high accuracy, and high rigidity. The distance between the center of the spindle and the guide rail surface is short, and the flip torque is small. It can provide a variety of cutting characteristics to meet the machining needs of different workpieces.
CNC System
Our CNC gantry machining center is compatible with FANUC, Mitsubishi, Siemens, and GCS CNC systems. It features reliable safety protection and fault diagnosis alarms, allowing for rapid shutdown in the event of a fault.
How to maintain the gantry machining center?
Surface maintenance: You need to regularly clean the internal and external surfaces of the CNC gantry machining center and remove burrs.
Spindle and tool magazine maintenance: Before starting the machine, inspect the tool magazine and clean the tools regularly. The spindle works after low-speed operation for 10 minutes.
Control system maintenance: You need to clean the dust on the surface of the electric control box and clean up the junk files inside the computer to prevent operational jams.
Lubrication system maintenance: You need to check the oil level in the lubricating oil tank regularly to prevent a situation of insufficient lubricating oil.
