Introduction to Axis Motion and Definition

This gantry cnc machine uses a fixed gantry and moving table motion to better meet the requirements of heavy milling on the machine's rigidity. Specifically, the worktable moves forward and backward on the base (this axis is defined as the X-axis); the saddle and the spindle box move left and right on the beam (this axis is defined as the Y-axis), and the spindle box moves up and down on the saddle (Z-axis).

Features of China CNC Gantry Milling Machine for Sale

• The mechanical structure, including the base, table, column, beam, and spindle box, is all made of HT250 cast iron, which provides the machine with super-high mechanical rigidity to handle heavy-load milling tasks.

• On the basis of high rigidity, the motion of the fixed gantry & moving table further optimizes the machine's performance and ability to handle heavy milling processes.

• The work table is designed to be dustproof and is equipped with a spiral chip removal device on each side. 

• The two spiral chip removal units are each powered by a 3-phase asynchronous motor.

• The spiral's action transports the chips to the collection device at the rear of the gantry cnc milling machine.

• To ensure working accuracy, the machine should be securely fixed to the plant's foundation. This will effectively eliminate vibration and resonance during processing, hence, improving the machining accuracy.

• Y and Z are designed to be dust-proof. Safety doors are installed around the machining area to protect operators.

• The milling head comprises three parts: a mechanical spindle, a spindle servo motor, and a spindle box. The spindle is a long-nose mechanical spindle, and the tool taper is BT50. It is powered by a 22KW KND AC servo motor.

• The machine spindle is equipped with several sprayers. Coolant is sprayed out from them during machining.

• The electrical cabinet is sitting on one side of the gantry and is equipped with a door-opening power-off switch.

• The primary electronic components are housed inside this well-sealed electrical cabinet.

• In order to protect the inverter and achieve quick stopping, braking resistors are installed in the cabinet.

• The automatic lubricator is installed outside of the cabinet. You simply need to preset the time, and it will automatically perform the oil-filling action when the time comes.

• All linear guide rails come with pressure blocks to ensure smooth motion and high accuracy.

• XYZ is all driven by TBI ball screws.

• Cast iron work table with T-slots. The workpieces are clamped down to the bed. 

• There is a step ladder located at the rear of the gantry to facilitate maintenance and inspection by operators.

• The cnc gantry drilling machine is equipped with a nitrogen counterbalance cylinder, and the gas cylinder providing the gas source is placed on the platform behind the gantry.

• The CNC system used is KND K2000, a system specially designed for drilling and milling machines. The operating interface is in English, and it also supports several other language options.

• The system comes with a manual pulse generator to facilitate the workpiece origin setup operation.

Application of Gantry CNC Machine

Applicable Field

The gantry mill for sale here is a good fit for performing the process of drilling, milling, facing, chamfering, slotting, tapping, threading, and spotting on long workpieces such as beams, structural steels, profiles, and other complex parts, etc.

Optional Configurations Available for EagleTec CNC Bridge Mill

Please select the following configurations or options according to your actual production needs:

Tool Magazine

Users have the option to add tool magazines based on their needs. The unit allows the machine tool to automatically change the tools required for machining without stopping. Compared to manual tool-change operations, it improves production efficiency by saving the cycle times required for tool change.

Spindle with Center Water Outlet Option

With the center water outlet spindle, we can use a U-drill that allows us to do high speed and Violent drilling. Except for this, here are some other benefits you can expect from a U-drill.

• The operating cost is low.

• High speed & efficiency.

• Smooth and clean finish; the hole wall finish reaches 2.8-3.2μm

Angle Head

Without the angle head, the machine can only process one face of the block, that is, the top surface. With it, we can machine up to 5 faces, all except the bottom surface.

Q & A

Q: What is a Gantry Mill?

A: The CNC gantry mill, also known as a CNC gantry milling machine, is a type of milling machine that features a gantry frame and a long horizontal working table or platform. This machine can use multiple milling cutters to process surfaces simultaneously, resulting in high machining accuracy and production efficiency. It is well-suited for batch and mass production of large workpieces, allowing for the processing of planes, inclined surfaces, spatial curved surfaces, and some complex parts.
