Types of Gantry CNC Milling and Boring Machines

The gantry CNC milling and boring machine is a versatile machine for boring holes, especially for large and heavy workpieces. Several types of gantry machines suit different processing needs.

• Gantry CNC milling machine

  The gantry CNC milling machine has an overhead frame that supports the cutting tool. The tool moves along the horizontal rails to remove material from the workpiece and create the desired shape. This type of CNC machine is ideal for large workpieces too big or heavy for conventional milling machines. It can handle giant materials like metal plates, blocks, and foams. The gantry design gives the milling machine a large work envelope. This means it can process wider and flatter workpieces. The tool's horizontal movement allows for more precise cutting and shaping of workpieces. Gantry CNC machines are suitable for machining tasks that require processing large areas.

• Gantry CNC milling and boring machine

  A gantry CNC milling and boring machine combines a milling and boring machine in one unit. It can perform both machining operations without having to move the workpiece. The machinings are done with the most outstanding accuracy and precision using a computer numeral control system with a human-machine interface control program. The workpiece is first drilled using the boring function. After that, the milling function refines all the workpieces to achieve the final desired shape.

• Gantry CNC plasma cutting machine

  This machine cuts thick steel plates and pipes. It uses an arc formed between the transferred electrode and the workpiece to melt the metals. The gantry design allows for high-speed cutting of large plates and metals.

• Double-row guide gantry unfinished machining

  The Double-row guide is a typical standard design for gantry machines. It has two guide rails and carriages supported by two rows, giving it more stability and accuracy. The machine has a fixed worktable that secures the workpiece while the cutting tool vertically descends to cut through the material.

Specifications and maintenance of gantry CNC milling and boring machine

The specifications of a gantry CNC machine will vary depending on the model. Below are some key specs and their descriptions. Details of the machine’s specifications will usually be available on the datasheet corresponding to the model.

• Maching size: This refers to the worktable length and width. An 800*600 gantry milling machine means the length of the worktable is 800 mm and the width is 600 mm. There are larger configurations like 2400*1200. The ideal size will depend on the dimensions of the material that needs processing.
• Machining thickness: The machining thickness is the maximum height of material that a worktable can accommodate. It will range anywhere from 2000 mm to 8000 mm in gantry machines used for large-scale projects.
• Maximum feed speed: The maximum feed speed indicates the ability of the machine to move the tool or material within the area of milling or cutting. This speed will affect how long it takes to process one piece of material and ultimately the level of production.
• Spindle speed: This refers to how fast the spindle will rotate to cut or mill the material. The common spindle speeds for a gantry machine are between 60,000 and 240,000 rpm. A higher spindle speed will make it easier to cut through hard material.
• Machine weight: The weight of the milling machine is determined by the manufacturer. Heavier machines offer more stability. An unstable machine can result in inaccurate cuts and a poorer quality of the finished product.

Like all CNC machines, the gantry device requires regular maintenance to operate smoothly and efficiently. Some manufacturers provide a detailed maintenance schedule for their machines. Below are some general maintenance tips that can be applied to most maschines a.

• The worktable gantry milling machine and other parts of the device will need to be cleaned daily to prevent the accumulation of debris and dust.
• Weekly inspections can be done to ensure all the belts, bolts, rails, guides, and other parts are in good condition.
• Lubrication of moving parts like chains and belts can be done at least once a month to facilitate smooth movement and reduce friction.
• The spindle and other parts of the machine subject to wear and tear can be replaced every three to six months, depending on frequency of use. These include bearings, belts, seals, and blocks.
