The GM-2-5AX is a 5-axis gantry mill designed for complex, large-part machining, such as airframe components, layup molds, and composite structures. The machine’s rigid steel construction provides a very stable cutting platform, and a 1" thick aluminum table is standard. A traveling guard protects the operator from chips and coolant, and keeps the workspace clean.

  • Dual-axis spindle head provides ±245 degrees of C-axis rotation and ±120 degrees of B-axis tilt 
  • 20,000-rpm HSK 63F spindle    
  • Rigid-steel construction
  • Traveling guard for chip and coolant containment
  • 1" thick aluminum table
  • Made in the USA

LARGE TRAVELS, 5-AXIS VERSATILITY

Whether you’re machining large airframe components, trimming complex composite structures, or shaping massive layup molds, the GM-2-5AX has the capacity and capability to handle even your largest parts. The 20,000-rpm HSK 63F spindle provides the speed and rigidity you need for long tools and high surface feeds, and the dual-axis spindle head allows you to reach nearly an surface for machining complex contours and difficult features.

GM-2-5AX Test Cut

The GM-2-5AX articulating head is able to machine all 5 sides of your part, allowing you to do all your operations in a single setup. Watch the GM-2-5AX in action in this short demo.

Overview

There are a number of technical details that make the GM-2-5AX gantry mill very different from all other Haas 5-axis machines currently available. These differences are explained in the following blocks. Keep scrolling to get a better understanding of the capabilities of this unique 5-axis machine.

Spindle
 

The GM-2-5AX features a 20,000-rpm HSK spindle perfect for trimming composite structures, finish-profiling 3D surfaces, and hole making.  

The high-speed spindle is best suited for composites, aluminum, plastics, Ren-Board, and other non-ferrous materials. The 20,000-rpm speed allows for very high surface footage, for great finishes and small tools.  

The integral spindle design allows for fast acceleration rates to get the spindle speed up and down quickly. Consult the torque chart for your application.

Gimbal Head
 

The GM-2-5AX is a full 5-axis “gimbal head” machine, where both rotary axes are mounted on the Z-axis ram, and the spindle/cutting tool assembly rotates, while the workpiece is stationary on the machine table. This allows the cutting tool to point at any angle within the rotary-axis travel limits.

G268 Feature Coordinate System

Feature Coordinate System (G268) is a new feature in the Haas control unique to this “gimbal head” style machine. By definition, the work plane is perpendicular to the spindle centerline. On all other Haas 5-axis milling machines, the spindle centerline is parallel to the Z-axis, so no matter the orientation of a workpiece mounted on a rotary table, the work plane is perpendicular to the Z-axis. This assumes fixed angle heads are not used . . . more on that later.

G268 Feature Coordinate System (continued)

Now that the spindle centerline (cutting tool) can tilt to virtually any angle, we created G268 Feature Coordinate System to simplify programming of planar toolpaths in tilted work planes, including canned cycles, circular interpolation, and cutter compensation.

Command G268 with X-, Y-, and Z-axis coordinates in the Workpiece Coordinate System to establish the zero point of a new Feature Coordinate System. The tilted work plane angle will be perpendicular to the current tool axis direction using the actual tool axis angles (B & C axes on GM-2-5AX). The tool axis direction may also be defined using optional address codes I, J, K with G268. This alternative method of defining the angles allows the use of G268 Feature Coordinate System with fixed-angle heads on 3-axis milling machines, as well as 2- and 3-axis lathes.

G253 Orient Spindle Normal to Feature Coordinate System

G253 Orient Spindle Normal to Feature Coordinate System simplifies programming tilted work planes when using multiple tools in the same tilted plane.

When G268 (Tilted Work Plane) is active, the tool axis direction and Feature Coordinate System are stored in the control. When work is finished with a particular cutting tool in the tilted plane, you can retract to a safe position and command a tool change. Once the tool is changed and repositioned to a safe location, command G253 (Orient Spindle Normal to Feature Coordinate System) to return the tool axis to the tilted work plane. There is no need to cancel the tilted work plane and define it again for the next tool, just because you performed a tool change. 

Vector Jogging

Machines with gimbal heads need a way to jog along the tool axis vector. Activate Vector Jogging mode by pressing the letter keys [V], then [J] followed by the [HANDLE JOG] key. Jogging can only occur by rotating the handle jog wheel. Exit Vector Jog mode by pressing one of the single-axis jog keys. Machines without a gimbal head but fitted with fixed-angle head toolholders allow the user to enter the fixed angle after entering Vector Jog mode.

The Vector Jogging feature aids in recovery from a power outage while drilling a hole at an angle. When power is restored, the control knows that the rotary axes were not zero, so it activates RECOVERY mode. Vector Jogging is used to remove the cutting tool from the workpiece before running the Power Up/Restart function to home the machine axes. This even works for tap recovery, if the machine was in a tapping cycle when the power failed.

Safe Zone Calibration for Crash Protection

 

The design of gimbal head machines makes them very useful for many applications, but the same features that make them useful, also make them more susceptible to a crash. The fact that the rotary axes can point cutting tools at virtually any angle, means the safe travel limits of this machine are dynamic, and change with machine position. Multiple axes are both involved in, and limited by, the definition of these limits.

The GM-2-5AX has permanent elements (see above left and right) that can potentially be involved in a crash, like the machine table, machine column, spindle head, tool changer, and machine bridge. It also has NON-permanent elements to consider, like tool length and part dimensions on the table.

The goal is to eliminate the possibility of a crash between permanent elements of the machine.

 

The GM-2-5AX software defines these potential crash zones, and stores their positions, based on data gathered during the probe calibration and Safe Zone calibration cycles.

Once established, the control prevents motion into the restricted zones, based on the current and upcoming position commands of all axes.

The simplest example is shown below. The Z-axis travel is maximized, so machining with the B-axis rotated to 90-degrees (image below, left) can be done as close to the machine table as safely possible. The problem is that the spindle nose could be commanded to run into the table if the B-axis is at zero degrees (image below, right). The Safe Zone feature limits Z-axis travel when the B-axis is at zero, and removes the Safe Zone travel limit when the B-axis is a 90-degrees (or minus 90-degrees).
