The manual is available in multiple languages, with a Declaration of Conformity for European customers.

Bar Feeder Setup and Operation

1. Introduction

The manual provides guidance on setting up and operating a bar feeder with Haas lathes, covering installation and adjustment of spindle liners, loading bars, and configuring the bar feeder for various bar sizes and shapes.

2. Spindle Liners

Spindle liners adapt the spindle bore size to fit the bar stock, ensuring smooth feeding and reducing vibration. Proper fitting is crucial for minimizing vibration and improving surface finish.

3. Bar Setup

• Loading Bars: Ensure bars fit closely in the spindle liner and are straight. Bars should be chamfered at the leading end and cut square at the end contacting the bar pusher.
• Transfer Tray Adjustment: Adjust the tray height to align with the spindle liner for smooth bar feeding.
• Push Rod Installation: Use appropriate push rods based on bar diameter to prevent bending.

4. Bar Feeder Setup Pages - NGC

Configure the bar feeder using the NGC setup pages by entering bar length, push lengths, and clamping lengths. Ensure the bar is loaded correctly and the chuck is clamped securely.

5. Classic Haas Control (CHC) Setup

Define push lengths using variables and ensure proper clearance between the push rod and collet. Set the reference position at the collet face for accurate bar feeding.

6. Loading Short Bars

Ensure short bars are long enough for at least two pick arms to handle them. Adjust the bar feeder settings accordingly to prevent crashes.

7. Programming Examples

Four programming examples illustrate different methods for cutting off parts and handling bar stock, demonstrating the use of subprograms and specific commands for efficient machining.

Overview: This document provides detailed programming instructions for operating a bar feeder with a CNC machine, focusing on various subprograms and commands used to manage bar feeding, cutting, and facing operations.

1. Specifications and Procedures:

• The document outlines the use of a cutoff tool with a width of 0.125" and a facing allowance of 0.025".
• Initial push length and part length, including allowances, are specified using macro variables (#3100, #3101, #3102).
• Programs start with a cutoff subprogram, which behaves differently based on whether it's a new bar or a repeated loop on the same bar.
• For new bars, the subprogram faces and cleans the bar end, while for repeated loops, it cuts off finished parts and prepares the bar for the next operation.

2. Programming Examples:

• Example 1: Demonstrates a basic program with a cutoff subprogram and bar feed command.
• Example 2: Shows a preferred method when the cutoff does not need to reach the centerline, using separate facing and cutoff operations.
• Example 3: Illustrates a double push method for increased rigidity, using two G105 commands with variable overrides.
• Example 4: Describes a conditional two-pass facing operation using the Q13 command for new bars.

3. Bar Feeder Counter and Macro Variables:

• The bar feeder can count parts, bars, or material length, with counters incrementing at each G105 command.
• Macro variables are used to set and track part length, initial push length, clamping length, and maximum counts for parts, bars, and lengths.

4. G-Code Reference:

• G105 Command: Used for bar feeding, with optional overrides for initial push length, part length, and clamping length.
• Q Modes: Special commands for setup and troubleshooting, including setting bar length, reference position, and unloading/loading operations.

5. Additional Information:

• For further details, maintenance procedures, and updates, users are directed to the Haas Service page online.

Overview: This document provides detailed instructions and guidelines for operating and maintaining the Haas Bar Feeder, focusing on G105 commands and maintenance procedures.

G105 Commands:

• G105 Q2: Pushes the bar a specified distance and clamps the workholding. Requires G105 Q4 command prior to use.
• G105 Q3: Sets the reference position from the bar face by subtracting the Part Length + Cutoff variable. Does not move the bar.
• G105 Q4: Loads and measures a bar, pushing it through the spindle to just before the chuck face.
• G105 Q5: Sets the end-of-bar position, stored in variable #3111.
• G105 Q6-Q9: Commands for unloading/loading the push rod and bar.
• G105 Q10: Loads and measures a bar to check the end-of-bar switch position.
• G105 Q11-Q12: Used for assembly access, bumping the bar transfer mechanism.
• G105 Q13: Used for multiple facing passes on a newly loaded bar, works with Next Generation Control machines.

Maintenance:

• Regular maintenance includes applying grease to the push rod and bushing monthly, aligning the grease fitting, and cleaning the transfer tray.
• Check for obstructions or wear in the bar path if feed problems occur.
