Moving Gantry vs. Moving Table Gantry Mills:

  • Moving Gantry: In moving gantry mills, the crossrail or gantry moves along the X-axis while the worktable remains stationary. This configuration offers stability to the workpiece, making it suitable for machining heavy or large components.
  • Moving Table: In moving table gantry mills, the worktable moves along the X-axis while the gantry remains fixed. This design is advantageous in situations where the workpiece is relatively small, and the table movement provides better accessibility and setup convenience.

3-Axis, 4-Axis, and 5-Axis Gantry Mills:

  • 3-Axis Gantry Mills: 3-axis gantry mills can move the cutting tool in the X, Y, and Z directions. This configuration is suitable for producing components with relatively simple shapes and features that do not require complex machining angles.
  • 4-Axis Gantry Mills: 4-axis gantry mills can perform 3-axis movements (X, Y, and Z) along with an additional rotational movement around one axis (typically referred to as the A-axis or C-axis). This rotational capability allows for machining complex contours and features from multiple angles, making it ideal for producing intricate components.
  • 5-Axis Gantry Mills: 5-axis gantry mills provide the highest level of versatility and precision. They can perform 3-axis movements and two rotational movements around two axes (usually the A-axis and C-axis). This allows for simultaneous machining from multiple angles, enabling the production of highly complex and contoured components.

Bridge-Type vs. Cantilever-Type Gantry Mills:

  • Bridge-Type Gantry Mills: In bridge-type gantry mills, the crossrail is supported by two vertical columns at each end, creating a bridge-like structure. This design offers exceptional rigidity and stability, making bridge-type gantry mills ideal for heavy-duty machining and precise milling operations.

Hybrid gantry mills combine the benefits of both moving gantry and moving table designs. These machines can have a stationary crossrail while the worktable moves along both the X and Y axes. The hybrid configuration offers a balanced approach, providing stability for heavy workpieces while offering better accessibility for setup and tool changes.

Portal Gantry Mills:

Portal gantry mills, also known as double column gantry mills, are characterized by their wide, portal-like structure. The crossrail is supported by two columns, and the worktable moves along the length of the gantry. Portal gantry mills are suitable for machining large and heavy workpieces, such as those used in the aerospace and marine industries.

Travelling Gantry Mills:

Travelling gantry mills are mobile gantry mills that can be moved along their X-axis. These machines are often used for large-scale machining tasks in industries like shipbuilding and construction, where the workpiece is too large to be moved to a stationary gantry mill.

Each type of gantry mill offers specific advantages and capabilities, and the selection of the appropriate type depends on the machining requirements, workpiece size, complexity, and the industry in which it will be used.

Working Principles of Gantry Mills


The working principles of gantry mills involve the integration of computer numerical control (CNC) technology, precise movements of linear axes, and the proper selection and operation of cutting tools. These principles govern the machining process and ensure the accurate and efficient production of complex components. Let’s explore the working principles of gantry mills in detail:

CAD/CAM Integration:

The machining process with a gantry mill begins with the creation of a Computer-Aided Design (CAD) model of the component or part to be manufactured. Engineers and designers use CAD software to design the geometry and specifications of the desired component.

Once the CAD model is ready, it is converted into a Computer-Aided Manufacturing (CAM) program using specialized software. The CAM program translates the CAD model into machine-readable code that contains instructions for the gantry mill’s movements, tool paths, cutting speeds, feed rates, and other critical parameters.

Tool Selection and Setup:

Before starting the machining process, the appropriate cutting tools are selected based on the component’s material and the desired machining operations. The cutting tools are installed in the gantry mill’s spindle, and the tool changer allows for automatic tool changes when required.

Additionally, the workpiece is set up on the worktable, and proper clamping is essential to ensure stability during machining. Workholding fixtures like vises, clamps, and pallet systems are used to secure the workpiece in place.

CNC Machining Process:

With the CAD/CAM program loaded into the CNC control, the large cnc machining process commences. The gantry mill’s spindle, which holds the cutting tool, moves along the X-axis, while the bridge or gantry moves along the Y-axis, following the programmed tool paths. The simultaneous movement of the X and Y axes enables the cutting tool to perform 2D and 2.5D milling operations.

For 3D machining, where multiple angles and contours are required, the A-axis and C-axis (in the case of 4- and 5-axis gantry mills) come into play. These rotational axes allow the cutting tool to approach the workpiece from different angles, enabling complex machining operations.

During the machining process, the CNC control continuously monitors and adjusts various parameters, such as cutting speed, feed rate, and coolant flow, to ensure optimal performance and precision.

Real-Time Monitoring and Feedback:

Modern gantry mills are equipped with advanced sensor systems that continuously collect data on various parameters, such as temperature, vibration, and tool wear. This real-time monitoring allows operators and the CNC control system to make adjustments if necessary to maintain the desired quality and accuracy of the machined components.

The data collected from the sensors can also be used for predictive maintenance, helping to identify potential issues before they cause a breakdown or affect the quality of the components being produced.

The working principles of gantry mills revolve around precision, automation, and the seamless integration of CAD/CAM technology with CNC controls. These principles enable gantry mills to produce complex components with high accuracy, efficiency, and repeatability. As a result, gantry mills have become indispensable tools in various industries, including aerospace, automotive, energy, defense, and more.

3. Okuma Gantry Mill

Okuma Corporation (オークマ株式会社, Ōkuma Kabushiki-gaisha) is a machine tool builder based in Ōguchi, Aichi Prefecture, Japan. It has global market share in CNC machine tools such as CNC lathes, machining centers, and turn-mill machining centers.

The company also offers FA (factory automation) products and servomotors.[2]It is listed on the Tokyo Stock Exchange and is a component of the Nikkei 225 stock index.The company was founded in 1898, as the Okuma Noodle Machine Co., to manufacture and sell noodle-making machines.

3. Okuma Gantry Mill

Eiichi Okuma, the founder of the original company, was working on how to make udon more effectively. He was using lathe to make “sticks”, that has an important role in cutting the udon noodle. But the lathes used in those days in Japan were of poor precision. This was one of big reasons which convinced Okuma to start making machine tools.[4] In 1918 Eiichi established Okuma Machinery Works Ltd. and started selling the OS lathe.

Okuma is a machine tool builder with a history of more than 100 years. Lathes were the main product category in the early days of company. The line now includes many CNC machine tools, including lathes, machining centers (mills), multitasking (turn-mill) machines, and grinding machines. Okuma’s Double-Column Machining Center has a large market share in Japan.

Most machine tool builders source their CNC controls from partners such as Fanuc, Mitsubishi Electric, Siemens, and Heidenhain. Several builders have developed their own CNC controls over the years (including Mazak, Okuma, Haas, Dalian Kede and others), but Okuma is unusual among machine tool builders for the degree to which it designs and builds all of its own hardware, software, and machine components. This is the company’s “Single Source” philosophy.

Okuma’s CNC control is called the “OSP” series. It offers closed-loop positioning via its absolute position feedback system. The “OSP” name began as an abbreviation for “Okuma Sampling Pathcontrol”.

In an industry that pushes hard for continual technological innovation, Okuma has often been an innovative leader.[5] For example, it has been among the leaders of development for thermal compensation and collision avoidance.[6] Thermal compensation is designing the machine elements and control to minimize the dimensional distortion that results from the heat generated by machining. This is done both by preventing heat buildup (for example, flowing coolant through machine elements formerly not cooled) and by detecting and compensating for temperature rises when they occur (for example, monitoring temperature with a sensor and using the sensor’s output signal as input to the control logic). Collision avoidance is designing the machine to predict and prevent interference, for example, having the machine “know” the form and location of all fixturing so that it can foresee a crash and stop its own movement before crashing. Recent innovation includes technology to avoid chatter, both by predicting and preventing it and by early automatic detection and correction (via dynamic changes of speeds and feeds) when it does occur.
