HBF - 12 - Control Screen

Revision A - 09/2025

Introduction

The Haas Bar Feeder 12 is equipped with a dedicated control screen that provides access to the following features:

  • User Parameters
  • Alarms
  • Factory Settings (view-only reference)

Note : This screen also has its own dedicated software available for download on HBC

User Parameters

Parameter 1 Push Length

This setting controls the push length of the commanded parts.

Ensure this parameter is the total length [1] of the finish parts + cutting off tool width + material removed during facing operation = X.XX in   

Important : The HBF-12 is a push to stop system and requires a stopper for consistant bar pushes.

Note : Slow down distance [2] needs to be set to reduce impact on the bar stopper. 

Factory Settings:

1.0 inch

0.50 inch

 

Parameter 2 Push Force

Chuck Open Force : Reccomended setting is 45 kg (This value varies depending on material weight)

Chuck Close Force : Reccomended setting is 15 kg.

Factory Settings:

30lb 

15lb

Parameter 3 Push Length Error Detection (Fix type)

This is a safety parameter that can be set by the operator as a secondary safety function in the event that the bar stop (turret) is miss positioned.

If the bar travel is :

  • Too short (Alarm 9)
  • Too long (Alarm 10)

Factory Settings:

OFF

0 inch

0 inch

Parameter 4 Push Length Error Detection (Swiss type)

This is a safety parameter that can be set by the operator as a secondary safety function in the event the collect is closed too early or too late.

If the bar travel is :

  • Too short (Alarm 22)
  • Too long (Alarm 23)

Note : This parameter does not apply to Haas machines.

Factory Settings:

OFF

0 inch

0 inch

Parameter 5 Initial Push Position

[ON] Parameter allows the use of multiple different bar lengths without the need of changing initial push position [1].

[OFF] Parameter push distance is the distance to the bar stop (turret).

Factory Settings:

ON

63.50 inch

Parameter 6 1st Feed Position

This parameter controls the position of the where the trolley pushes the bar before the pushrod is engaged.

Ensure that the trolley push distance [1] is in between the collect of the pushrod and the clamping jaws to ensure correct engagement.

Slow down distance [2] is set to reduce the chance of bar overshoot. 4 in is the reccomended distance to alow the trolley to decelerate.

Push force [3] is reccomended to be set at 45 kg but varies according to raw material weight.

Factory Settings:

74.50 inch

5.0 inch

40.0 lb

Parameter 7 Bar end position

This parameter [1] is set by jogging the pushrod to the back of the collet and leaving a gap of 0.25 in (5 mm).

Factory Settings:

149.0 inch

 

Parameter 8 Oil Pump Shutoff

When the push rod position is greater than position setting [1], the hydraulic oil pump is shut off.

Note : The oil pump lubricates the jaws of the anti-vibration device when the work piece is spinning within it. The oil pump is not needed to lubricate the pushrod once it reaches the anti-vibration device.

Factory Settings:

 28.0 inch

Parameter 9 Anti Vibration Device Pusher Clearance

This parameter ensures the AVD jaws are not preventing the pushrod from advancing past it and adds additional support to the push rod as the material is being machined.

The AVD should open [1] when the pushrod collet is near AVD the jaws.

The AVD should clamp [2] when the pushrod collet is past the AVD jaws.

When this parameter is on the AVD behaves the same as the machine chuck. The AVD opens allowing the push rod to advance then clamps to support it during machining.

Factory Settings:

ON

90.39 inch

121 inch

Parameter 10 Spindle Anti Vibration Device (Not applicable to Haas machines)

This parameter ensures the SAVD wheels are not preventing the pushrod from advancing past it and adds additional support to the push rod as the material is being machined.

The SAVD should open [1] when the pushrod collect is near the it

The SAVD should clamp [2] when the pushrod collect is past the wheels.

When this parameter is on the SAVD behaves the same as the machine chuck. The SAVD opens allowing the push rod to advance then clamps to support it during machining.

5.3 HBF - 12 - Material Loading

HBF - 12 - Material Loading

Revision B - 04/2026

Material loading

1

The adjustable material support holds the bar stock at the correct height during bar feeder operation. This support helps stabilize the material and ensures proper alignment as the bar is fed into the machine. [1]

During the loading cycle, the material support lowers to allow a new bar to enter the feeder. At the same time, it prevents the remaining bars in the holding zone from feeding forward. Once the bar is loaded, the support returns to the set height to properly support the material during operation.

2

Use an Allen wrench to adjust the material support height. Turn the adjustment screw [1] while observing the indicator dial until it aligns with the desired bar stock diameter.

This is a mechanical system, the adjustment directly raises or lowers the support height. Once the correct position is set, no additional locking action is required.

5.4 HBF - 12 - AVD SETUP

HBF - 12 - AVD Setup

Revision A - 04/2026

Introduction

1

The Anti-Vibration Device (AVD) on the bar feeder is used to stabilize the bar during operation and reduce vibration while feeding material into the machine. The AVD can be adjusted to accommodate bars of different diameters, helping maintain proper bar support and improving feeding accuracy.

Proper installation and adjustment of the AVD are important to ensure smooth bar movement and to minimize vibration during operation. This procedure outlines the installation and setup of the AVD components on the bar feeder.

2

In order to adjust the AVD you must remove the AVD extension tube assembly.

3

To adjust the AVD, use the two screws located on the top of the device. Refer to the plaques on the AVD that indicate the directions for larger and smaller adjustments.

Closed Position Adjustment (Material Diameter): Actuate the AVD to the closed position. Slide the bar through the AVD and adjust the Material Dimension screw until the bar can no longer be rotated by hand. Then gradually relieve the adjustment by turning the screw counterclockwise in ¼-turn increments until the bar can rotate and slide freely. [1]

Open Position Adjustment (Limit): The open position is set by the pusher OD. Ensure the AVD is not actuated. Slide the pusher forward until its largest diameter is positioned within the AVD jaws. Adjust the Limit screw using the same method as above—tighten until rotation is restricted, then back off in ¼-turn increments until the pusher can move freely.

Note: Providing too much clearance will increase vibration. Setting the clearance too tight may cause the bar feeder to jam.

5.5 HBF - 12 - Enable Code

HBF - 12 - Enable Code

Revision A - 03/2026

Enable HBF12

NOTE: The Macros option must be enabled to run this procedure. This is a paid option and may not be installed on all machines. To verify if Macros is enabled, go to Parameters > Features and confirm that Macros is selected. If Macros is not enabled, refer to How to Enter Option Codes – AD0932 for instructions on loading option codes.

The HBF‑12 bar feeder uses G105 as its command interface. On Haas machines, G105 is aliased to a macro program stored in the control. Download the G105 Macro program and follow the procedure below to load it into the Haas Control.

O09010_G105_Barfeeder_12_Code

G105 Aliased Program Setup

1.     Load Program O9010 onto Haas Control and Press [F2] to copy it to Memory > 09000 folder.

2.      Navigate to Settings > Alias Codes

3.      Set G Macro Call O9010 to “105”

Part Counter Setup

1.      Navigate to Current Commands > Timers

2.      Set Macro Label #1 to “Part Count”

3.      Set Macro Assign #1 to “10200”

Barfeeder Operation Macro Var Setup

1.      Navigate to Current Commands > Macro Vars

2.      Set #10201 to your desired Max Part Count.

3.      Set #10203 to your Part+Cutoff Length. Using the terms of the current HBF, this would be your “D” value.

4.      Set #10206 to your desired Push Wait time. This value will vary and depends on the length of your push. If desired we can put together a table of recommended waits based on push length. 

Chuck Open Spindle Rotation Setting

1.      Navigate to Settings

2.      Type “283” then press [F1]

3.      Set Setting 283 to “500”. This setting must be set above 30 (what the g105 program currently uses) to allow the spindle to rotate when feeding a new bar in after a bar change, otherwise it will alarm. 

G105 Aliased Program

G105 [I n.nnn] [J n.nnn] [R nnnnn] [Q13]

This program accepts the address codes I, J, Q13, and R.

The I value sets the initial bar push length. The J value specifies the length of additional pushes that occur during the same part cycle. Both addresses assume the turret has been pre-positioned to act as a hard stop. When the program is executed, G105 moves the turret to the defined I or J position.

Warning: Because the turret is used as a hard stop, it is important that the I, J, and parameter #10203 values are set correctly. Any program using I and J addresses should be tested at 5% rapid before running at normal speeds.

The R address calls subprograms, similar to the P address used on the Haas Bar Feeder V2. For example, program 00005 would be called using: G105 R5

The Q13 syntax functions the same as on the Haas Bar Feeder V2. To conditionally call program 00005 at a new bar, use: G105 Q13 R5

This program is written for bar feeding into a hard stop to define the push length. When using a hard stop, the operator must change to the correct tool and position the turret before calling G105. The program runs until the maximum part count is reached or the bar feeder runs out of material.
