Haas haas sb ROTARY TABLES INDEXERS

ROTARY TABLES & INDEXERS

HAAS AUTOMATION INC.

In the beginning...
In 1983, Haas Automation, Inc., developed the first fully programmable 5C collet indexer. Built with quality materials, and engineered to be dependabte and highly accurate, the unit was a tremendous success. By closing the gap between cumbersome, manually operated indexers and very expensive true 4th-axis machining centers, Haas established itself as an industry leader in automated 4th-axis parts positioning. By assisting industry leader in the quest to increase productivity through automation, Haas has become one of America´s leading builders of machine tools and rotary tables. After more than a decade of ongoing refinement and development, Haas rotary products continue to dominate the industry with quality craftsmanship, dependable operation and affordable prices. Today, Haas has a line of more than 32 models of rotary tables and indexers that deliver the same high quality and extremely accurate performance that is the Haas made-in-America trademark.The full line of Haas rotary products includes many
specialized units designed for maximum productivity. From the multi-head HA5Cs to the tilting T5Cs and TRT 160 and 210 models, Haas continues to lead the way to higher productivity through automation. Haas rotary products are built from top-quality materials and undergo constant re-engineering and refinement to offer only state-of-the-art technology. Constructed of heavy-duty materials, and designed for dependable day-in, day-out operation, Haas rotary products are the benchmark by which all others are measured.
Take a close look at the components that go into our rotary tables. Haas manufactures all critical components in-house at our
modern California machining facility. By controlling the machining process, we re able to deliver the kind of quality and accuracy
our customers demand.

One example of this is the indexing accuracy of our rotary tables. At the core of every Haas rotary table is a large-diameter, aluminum-bronze worm gear meshing with a ground steel-alloy worm (hardened to 60 Rc) submerged in a synthetic oil bath. The secret to Haas´ indexing accuracy is cutting the worm gear while it's attached to the spindle, rather than assembling the finished worm gear to the spindle as other rotary table manufacturers do. Each assembled spindle is individually trammed-in on a CNC gear hobber to a maximum 5-micron runout; then the worm gear is precision cut. This process provides the utmost in concentricity between the large-diameter ball bearings and the worm gear, ensuring many years of smooth, extremely accurate and bind-free operation. This is just one of the many quality designs that go into each and every Haas product.

1)Fast Alignment - All Haas tables and tailstocks have 0.625" alignment keys. These keys are parallel to and centered on the spindle. When used on Haas VMCs with their precision T-slots, you can bolt on a rotary product without the need to indicate
the table in. 

2)Maіn Body - Class-30 iron is used for superior damping qualities. Extremely rigid, it damps vibration and deflects machining forces. Machined by Haas in only two operations on FMS machinery. 

3)Turntable Platter - Haas uses only 4140 heat-treated steel alloy for our platters. Machined in-house, they deliver superior strength and durability. Made by Haas.

4)Servo Control - The original, and still the best control available. More than a decade of ongoing refinement has produced near perfection, yielding absolute control with the most user-friendly programming available. It's still the benchmark other manufacturers have unsuccessfully tried to copy. Designed and built by Haas.

5)Bearings - Deep-groove radial bearings withstand loads up to 31,000 lb. By supporting the worm gear on both sides with these massive bearings, Haas is able to deliver superior performance and dependablLe operation. Precision-made in the USA.

6)Worm Gear - Haas´ large-diameter aluminum-bronze worm gear is hobbed on a CNC gear hobber and inspected on a
Klingelnberg gear analyzer. Made by Haas.

7)Worm Drive Shaft - Our drive shafts are made of 8620 steel hardened to Rc 60, then CNC precision-ground, and ínspected to a 2-micron runout on a Klingelnberg gear analyzer. Made by Haas. 

The Haas Servo Control

At the heart of all Haas rotary products is the Haas Servo Control. Refined to near perfection by more than a decade of development, it offers the utmost in versatility, coupled with fast, easy, flexible programming. The Haas control always incorporates the latest in high-speed microprocessor and drive technology.

Haas´ exclusive software replaces failure-prone mechanical components, and it includes a self-diagnostic subroutine which maximizes uptime. A single circuit board controls all main functions.

When used with any CNC machining center, the control functions as a semi-4th axis, activated by a single M function. Easy interfacing, fast setup and low cost make Haas the perfect alternative to cumbersome, high-priced, offshore 4th-axis machines.

Using the controls standard features, odd number bolt circles and uneven hole spacing are easily achieved with simple programming. 

You can program the control to rotate the spindle in either direction, in step sizes from 0.001 to 999.999 degrees. There can be up to ninety-nine different steps in memory, and each step can be repeated (or looped) up to 999 times. The memory is non-volatile, so programs are fully retained, even when the power is turned off. You may store up to seven separate programs. (The SCO-TRT210 stores up to four programs.)

You can easily achieve three times the performance of a manual device with a Haas control operating the rotary table of your choice. Add to this built-in-the USA Haas quality and reliability, and your decision becomes very simple. Haas has the solutions you need.

Haas rotary products can be interfaced to virtually any type of machíne. There are three distinct methods of interfacing listed below, each with different capabilities and limitations. Thousands of Haas rotary products have been successfully interfaced to a very wide variety of machines over the years. Haas Automation's Service Department can provide expert advice on the best interface for any application.

True 4th-Axis Direct Control Via Host Machine
This method does not use the Haas Servo Control unit; instead, an amplifier built into the host machine provides power and true multi-axis simultaneous motion control. Almost all Haas CNC machine tools can be fitted with additional amplifiers that work with off-the-shelf Haas rotary products. With this method, the rotary axis is programmed and controlled directly by the host control - just like the X, Y and Z axes. For direct control on machines other than Haas, some Haas rotary products can be refitted with compatible servo motors (Fanuc, Yasnac, Allen Bradley, etc.).

4th-Axis Control Via R5-232 Port
This method requires use of a Haas Servo Control unit and a host machine capable of sending data via an RS-232 line. All Haas CNC machine tools can send such data to control up to three daisy-chained Servo Controls. 0n Haas CNC machines, the rotary axis is programmed directly on the CNC control - just like the X, Y and Z axes - and no M codes are required. All other CNC machines
require macro function capability, an external Mcode controlled relay, and an M-FIN connection. Programming is still done at the CNC control; however, it is in the form of macros, and M codes are required for synchronization.

Semi 4th-Axis Control Via CNC lnterface Cable
This method requires use of a Haas Servo Control unit and 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's program memory. Each pulse of the host machine´s 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. Fully-synchronized multi-axis motions cannot be performed with this method. This method can be used with machine tools that have no controls.
NOTES
Servo Controller can also be interfaced to PLC units and computers for general-purpose use. Please contact Haas Automation for details.
*The term "4TH AXIS" is used as a genera/ description. Unit may operate as any axis depending on host machine.

4th-axis ordering information
When ordering any Haas rotary table or indexer for use on a Haas machining center, you do not need a servo control unit. We do, however, suggest you get the control unit so you can use your rotary table on other machines. Please discuss with your dealer the make and model of the CNC machine you intend to use your new rotary tabLe with before placing an order.

Now available — true 4th-axis custom motor configurations
Haas rotary products can now be ordered with various motor configurations. This option allows a Haas rotary table to be used as a true 4th axis on many CNC machining centers other than Haas VMCs. In order to properly set up a Haas rotary table with an optional motor, you will have to supply detailed information about the interfacing machine. Please call your dealer for details,
or contact Haas directly at 800-331-6746.

Brushless Motor Technology

Most Haas rotary tables are now available with brushless servo motor technology. These highly reliable, high-performance servo drives provide greater torque for heavy operatíons, and yield higher acceleration/deceleration rates to reduce cycle times. With no brushes to wear and generate dust, motor maintenance is reduced and reliability is substantially increased. And, since the heat-producing windings are attached to the outer shell, these motors run cooler, are more compact and have a longer life than brush-type motors. Haas brushless rotary tables are currently available in most models. Contact Haas or an authorized Haas distributor for further information. Keep ín mind, brushless rotary tables will work seamlessly with any new Haas CNC machining center that also utilizes brushless servo motor technology. For Haas machines furnished with standard brush motors, or other manufacturers CNC equipment, you can utilize Haas brushless rotary technology by using a Haas brushless servo control unit with your new brushless rotary table.
