Overview

The Haas VR Series machines combine an upgraded version of the integrated gimbal spindle used on our GM-2-5AX, with our extremely popular VF Series VMCs. The result is a very versatile full 5-axis machine tool.

This is a very different machine tool compared to our previous versions of the VR Series machines. The main technical difference is the rotary axis configuration. The previous generation VR Series machines used an A-axis mounted on a B-axis to support the spindle, whereas this new version is a B-axis mounted on a C-axis. This means that G-code programs developed for the discontinued VR machines are not compatible with the new versions, and post-processors will have to be modified to reflect the different axis configuration.

There are a number of technical details that make the VR Series mills very different from many 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 these unique 5-axis machines.

Spindle

The VR Series mills features a 20,000-rpm HSK-A63 integral-motor spindle. This upgraded spindle features 50% more power and 40% more torque than the HSK-F63 spindle in our GM-2-5AX. More power means more aggressive material removal is possible. This is not just a finishing machine!

While the high-speed spindle is best suited for aluminum, composites, and other non-ferrous materials, the increased power allows cutting a variety of steels. Balanced material removal rates can be achieved with modern high-efficiency milling techniques.

The 20,000-rpm speed allows for very high surface footage, for great finishes and small tools.  

The integral-motor 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 VR Series mills are full 5-axis “gimbal head” machines, where both rotary axes are mounted on the Z-axis, 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.

The dual-axis spindle head provides ±245 degrees of C-axis rotation and ±120 degrees of B-axis tilt, and has powerful pneumatic brakes on both axes for rigid 3+2 machining.

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 most 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 that fixed angle heads are not being 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 and C axes on VR Series machines). 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.

Refer to the Operator’s Manual for more details on G268.

G253 Orient Spindle Normal to Feature Coordinate System

G253 Orient Spindle Normal to Feature Coordinate System simplifies the programming of 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 VR machines have 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 VR Series 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).

*Haas machines are designed to operate on 220 VAC (200-240 VAC) power. An optional internal high-voltage transformer (380 - 480 VAC) is available for all models, except the Desktop Machines, CL-1, CM-1, and SR Series routers. This optional high-voltage internal transformer is not field installable; it must be ordered with the machine.

Haas machines destined for Europe and the UK are configured with an internal high-voltage non-isolated transformer to operate on 400 VAC, except the Desktop Machines, CL-1, CM-1, and SR Series routers. 

ATTENTION! Optional high-performance spindles may have a higher power requirement than the standard spindle. However, if the spindle horsepower (kW) does not change, the power requirement remains the same. Verify the power requirement before running power for your machine.

† Air consumption on 40-taper DC Series machines may be higher, when Through-Tool Air Blast (TAB) is activated.
