Overview

Haas rotary tables and indexers are fully automatic programmable positioning devices that can be moved to several different machines allowing versatile shop configurations.

Rotary/indexers are made up of two interfaced parts: the mechanical head that holds the workpiece and the control that can be the Haas Brushless Rotary Control (Servo Control) and/or the CNC machine.

The interface method can be:

  • True 4th and 5th axes simultaneous control of the rotary/indexer as described in the Haas Mill Operator’s Manual. No Servo Control unit is used.
  • Semi 4th and 5th axes control using the CNC Interface Cable and the Servo Control described in this manual.
  • Semi 4th and 5th axes control using the RS-232 port and the Servo Control described in this manual. 

Semi 4th and 5th Axes Control

The system of rotary/indexer and Servo Control unit is defined as a semi-fourth axis. This means that the table cannot do simultaneous interpolation with other axes. Linear moves or spirals are generated by having an axis of the mill move at the same time the rotary table moves. Refer to “Simultaneous Rotation and Milling” on page 31 for details. This method requires a host machine capable of closing a relay (or switch). Most CNC machine tools are equipped with spare M codes, which can be used to close a relay. Indexing commands are stored only in the Servo Control program memory. Each pulse of the host machine relay triggers the Servo Control to index to its next programmed position. After finishing the index, the Servo Control signals that it has finished and is ready for the next pulse.This method can be used with machine tools that have no controls.

4th and 5th Axes Control Using the RS-232 Port

This method requires use of a Haas Servo Control unit and a host machine capable of sending data via an RS-232 cable. It also requires macro function capability, an external M-code controlled relay, and an M-FIN connection. Programming is still done at the CNC control.

Servo Control

Servo Control

The Servo Control unit is specifically designed for rapid positioning of parts in secondary operations, such as milling, drilling, and tapping. The Servo Control unit interfaces well with automatic machines, such as NC mills and automatic production machines. Your equipment can remotely activate the Servo Control for fully automatic operation. Workpiece positioning is accomplished by programming angular movement and storing these positions in the Servo Control. Up to seven programs can be stored and the battery-powered memory retains the program when the Servo Control is turned off. The Servo Control is programmed in step (angle) sizes from .001 to 999.999°. There can be 99 steps for each program, and each step can be repeated (looped) 999 times. The optional RS-232 interface is used to upload, download, enter data, read position, start, and stop operation.

How to Use This Manual

To get the maximum benefit of your new Haas machine, read this manual thoroughly and refer to it often.  

IMPORTANT:  Before you operate the machine, read and understand the Operator’s Manual Safety chapter.

DECLARATION OF WARNINGS

Throughout this manual, important statements are set off from the main text with an icon and an associated signal word: “Danger,” “Warning,” “Caution,” or “Note.” The icon and signal word indicate the severity of the condition or situation. Be sure to read these statements and take special care to follow the instructions.

 

Description Example
Danger means that there is a condition or situation that will cause death or severe injury if you do not follow the instructions given.  DANGER: No step. Risk of electrocution, bodily injury, or machine damage. Do not climb or stand on this area.
Warning means that there is a condition or situation that will cause moderate injury if you do not follow the instructions given.  WARNING:  Never put your hands between the tool changer and the spindle head.
Caution means that minor injury or machine damage could occur if you do not follow the instructions given. You may also have to start a procedure over if you do not follow the instructions in a caution statement. CAUTION: Power down the machine before you do maintenance tasks.
Note means that the text gives additional information, clarification, or helpful hints. NOTE:  Follow these guidelines if the machine is equipped with the optional extended Z-clearance table.
