Introduction

The HSK-A63 option has been integrated into our previous 40T 15k inline spindle design, and this will be built on our production floor.  The HSK-A63 utilizes clamping unit style B by OTT-JAKOB. The HSK-63A spindle option is currently available on the EC-400, EC-500, VC-400/SS, UMC-1000/SS, the VM-2, VM-3, and VM-6 with optional max speeds of 12,000 or 15,000 RPM

The HSK-F63 option  is only available on the GR-712 5ax and the GM-2-5ax. This model will have a max speed of 25,000 RPM.

The HSK-A63 option is available on the VR Series and the GM-2-5ax. This model will have a max speed of 20,000 RPM. 

     The HSK type toolholders are unlike other tool-holding solutions we use in that they are hollow, shorter, and have a steeper shank.  The acronym HSK is translated from German as hollow taper shank.  Since they are hollow and shorter, they are lighter and have the ability to perform faster tool changes. They clamp the toolholder radially and axially, contacting the toolholder with the spindle face.  HSK toolholders are in general more rigid and thus reduce any noise from resonant frequencies generated within the system.  This leads to reduced chatter and an overall exemplary toolholding system.

Refer to the Tool Holder and Pull Stud - Specification reference document for the HSK63A tool holder specifications.

How it Works

        The HSK unit clamps the tool holder from the inside using gripper segments [6] that hook onto a ramp within the toolholder [10].  They press outward and thus clamp force increases from centripetal force as the spindle increases in speed. 

WARNING: Never run an HSK spindle without a toolholder.  Centripetal force will damage the gripper segments.

The TRP (tool release piston) now has an additional switch that will sense if a tool is installed to the spindle or not.  It should not allow the spindle to run without a tool. It senses an extra groove that is installed to the guide release of the spindle.

      The clamping cone [4] screws onto the drawbar.  When the drawbar unclamps the gripper segments [6] will slide back along the ramp of the clamping cone and allow a tool to be removed or inserted.  They will then slide forward and expand when the drawbar clamps. The spacer unit [8] applies a pre-load to the segments that keeps them securely installed to the spindle shaft bore they sit in.  Push-out is set by tightening or loosening the clamping cone; the locking screw [5] then locks the clamping cone into place once push-out is set. The bronze bushing [2] secures in the clamping cone via a snap ring [1]. The bushing and lip seal [3] mate with a coolant tube, if there is one, inside of the tool holder. The other seals consist of two O-rings [7] and [9]. All of these components must be sufficiently greased or clamp force could be lost and the system will wear prematurely.

 

Symptom Table

Symptom Possible Cause  Corrective Action
Coolant has filled up inside the clamping unit. TSC was run. The tool holder had a coolant tube installed.  The tool was not a TSC tool. The lip seal in the clamping cone has failed.  Replace the lip seal.  Clean and lubricate the entire clamping unit.  Inspect the small o-ring near the drawbar threads as it may also need to be replaced.
TSC was run. A coolant tube was not installed in the tool holder. Clean and lubricate the entire clamping unit.
TSC was run. A correct tool holder and tool were used. The lip seal is damaged. Replace the lip seal.  Clean and lubricate the entire clamping unit.
 The coolant tube is loose in the tool holder, or the o-ring in the coolant tube had failed. Tighten the coolant tube, replace the o-ring as needed.  Clean and lubricate the entire clamping unit.
The clamping cone locking screw is difficult to tighten or loosen while setting pushout. The locking screw is installed backwards. Remove the clamping cone.  Remove the locking screw.  Turn the locking screw around and install it onto the clamping cone.  Install the clamping cone and set pushout.
The hex in the locking screw is damaged. Remove the clamping cone.  Remove the locking screw and replace it.  Install the clamping cone and set pushout.
Clamp force is low. Clamp force gauge is not set up properly or is malfunctioning. Measure clamp force with a second gauge to rule this out.
Pushout is incorrect. Adjust clamping cone positon to obtain the correct pushout distance.
Lubrication is failing. Lubricate the clamping unit gripper fingers and clamping cone.
Clamping unit components are worn. If pushout and lubrication are correct, inspect the clamping cone and gripper fingers for wear.  Replace as needed.
Drawbar springs have failed. This is very unlikely.  Do not assume this is the cause unless all other solutions have failed.
Tool holders are hard to remove from the taper. Pushout is set too low.  (When pushout is set too low clamp force may measure very high). Adjust clamping cone position to obtain correct pushout distance.
Gripper finger are loose in pushout condition.  This will only be noticed when the drawbar is actuated without a toolholder in the taper. Clamping unit space is bound up or its spring has failed. Disassemble the clamping unit, replace the spacer.  Inspect the backup ring and large o-ring, replace as needed.
Z-axis position accuracy is inconsistent after using a probing system. The tool probe was not seated correctly. Refer to the HSK - Spindle Probe Seating section below.

Clamping Unit Replacement and Pushout Adjustment

Required Maintenance

WEEKLY:

  • Check the packing ring (lip seal) for wear
  • Check the gripper for damage, dirt, and for sufficient grease
  • Re-grease all edges of the clamping cone and gripper segments that contact each other
  •   Note: Do not mix grease (the spindle was assembled using METAFLUX grease: Metaflux paste 70-8508 or Metaflux spray 70.82 are acceptable). METAFLUX  product is not available from Haas Automation and can be purchased off-the-shelf
    •  If the unit is very dirty remove the clamping unit and clean thoroughly
    • Do not spray compressed air into the spindle clamping unit - it will blow out all the grease
    • Always leave a protective HSK-63A toolholder in the spindle that does not have through-holes to prevent contamination of the clamping unit

6 MONTHS OR 200,000 TOOL CHANGES:

  • Measure the push-out in the unclamped position (10.5 mm +/- 0.1 mm; 0.41 in +/- .004 in)
    • Re-torque the locking screw through a clamped tool if you needed to adjust the push-out
  • Test clamp force (pull force):
    • HSK-A63: 2,835 - 4,050 lbs 
    • HSK-F63: 1,730 -  2,472  lbs
    • If clamp force is not met you may need to re-grease the clamping unit, replace broken gripper segments, or replace a worn drawbar. Troubleshoot accordingly.

YEARLY OR  500,000 TOOL CHANGES:

  • Replace the packing ring (lip seal)
    • It's not necessary to remove the bronze bushing to replace the seal, use pliers to grip the seal

HSK - Spindle Probe Seating

When the probe is inserted into the spindle, it is possible that the probe may not be seated correctly. This will cause z-axis positioning errors for the cutting tools and may result in a scrapped part.

To avoid this problem, do the following:

  • Perform a tool change so that the probe is inserted by the double arm, not by hand.
  • After the probe has been loaded into the spindle check with a piece of paper that there is no gap between the probe and the spindle taper (see image to the right).
  • For Haas HSK A63 Spindle: If there is a small gap, refer to Set TRP Clamp Switch section in the HSK-A63 - Spindle Drawbar - Push Out procedure and adjust the clamp switch as described.

HSK tool loading

Push tool release.

Insert the tool holder into the spindle and if the face of the tool holder does not mate flush with spindle face the tool is not oriented properly. 

Remove the tool holder and rotate it 180 degrees.

Reinsert the tool holder and confirm the faces mate.

 WARNING: If a tool is inserted 180 degrees out the spindle will not rotate, however a tool change can be commanded which could cause a tool change failure or the tool to be dropped.

Special Tools Required

        All of the following tools need to be purchased in order to properly maintain and service our new HSK spindles.  These tools can be purchased off-the-shelf.  You can aquire these tools from anywhere you like, links are provided to give an example of the less common tools.  TAC Rockford and Advanced Machine Engineering Co. have good options for HSK tooling, and they also sell sturdy cases with different kit options to keep all of the tools together and protected. All tools need to be purchased in 63A and F versions or with adapters for each.  Keep tools calibrated and clean.

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).
