homemade rotary table brands

That is the route I went. I found a new, old-stock Bridgeport 15" on ebay listed as "pickup only". Had an acquaintance in the area that was willing to pick it up for me. I won it for $200 give or take. I built a swing-arm on the side of my mill column that the ro-tab bolts to using the t-slots of table top (so the bottom is smooth). I just swing the arm out over the mill table, crank the knee up to take the pressure off the bolts so I can remove then, slide the rotab where I need it and bolt it down. The only time I ever "lift" it is if I"m attaching it to the 90 degree mount (got that from the same seller for $60 on ebay). I will say that if you do a lot of work with the table on 90 you may want to just go for one built for either orientation, and you may want to go smaller. I don"t do much 90 degree work and I"ve always been able to "make it work" when it was an issue. IE, I was once milling some key-ways spaced precisely around a small circular element (1.5" diameter) so I used my rotab (this was before I had a proper collet indexer). I had to extend the part out further from the table so the table (about 18" high when on the 90 degree mount) could stand up beside the head while the quill did the machining. You wouldn"t have that problem with an 8" rotab.

Whether your CNC control has AC or DC drives, uses Fanuc, Mitsubishi, Yaskawa, Glentek, Siemens, Baldor, etc. we can build your rotary table with a compatible motor for just about any 4th axis-ready machine on the market! If you need help getting a machine 4th axis ready, we also supply the parts you need; such as amplifiers, drives, cables and connectors. If your application does not require simultaneous 4th axis cutting, we offer an easy-to-program, single-axis control box that can be M-function interfaced to your CNC machine. The control box can either be programmed directly or fed data via RS-232 for fast, accurate indexing to any angle.

Are you looking for an accessory to boost the precision of your modern machining centers? CNC rotary tables provide a versatile tool in expanding the capabilities of your machines. They allow for precision positioning during 4 and even 5 axis cutting operations, thereby transforming 3-axis machinery into CNC machines with heightened accuracy. CNC rotary tables are a cost-effective solution to perform complicated machining tasks, with additional benefits such as increased productivity, efficient use of labor and materials, and better quality control.

Additionally, CNC rotary tables can be used independently to mount other components on a table, including trim attachments and chucks for drilling applications. CNC rotary tables offer considerable advantages that promote their usefulness in a variety of industrial settings.

Everyday items such as smartphone cases and shells for tablet PCs, alongside other metal bodies for consumer electronics, are processed with these advanced machine tools. As multi-axis machine tool technology matures, demand for rotary tables with enhanced accuracy and rotational speed is rising. Taiwan"s Industrial Technology Research Institute (ITRI) has addressed this market trend by developing an advanced dual-axis rotary table with integrated Renishaw RESOLUTE absolute rotary encoders and Panasonic serial communication protocols for direct interfacing with Panasonic drives and controllers.

The rotary table is a key part of the machine tool, particularly for complex machine tool operations such as drilling, milling and turning. Machine tool manufacturers have adapted their product offering to suit the processing requirements of customers. Rotary tables allow scalable processing by adding a fourth or fifth axis to the traditional three axes of a CNC machining centre. Modern 3-axis machining centres require multiple setups each with its own fixturing requirements, as the workpiece is static, whereas 5-axis machines enable the user to effectively machine on five sides of a workpiece (top, front, rear, left and right) in one clamping, which significantly reduces total cycle and setup times. On-machine probing may also be applied to reduce set-up time, enhance automation and maintain the accuracy of critical components.

ITRI"s senior engineer on the project, Mr. Kuan-wen Chen, outlines their motivation: “Rotary tables on the market are either uniaxial or biaxial (dual-axis) and comprise a workpiece table, external housing, main bearing, servo motor and drive components, an encoder and braking system. In order to reduce costs, all of the components except the servo motor and encoder were either developed in-house or locally procured. After several years" development, the overall build cost of the current ITRI design, when compared with competing international brands, is over 50% lower and our ultimate goal now is to transfer these technologies and solutions to local manufacturers to help them develop competitive rotary tables with high cost-performance (CPI).”

ITRI"s rotary table features a 360° full rotation axis and a 170° tilt axis, both with their own direct-drive (DDR) motor which provides high-torque, high-rigidity, low wear and zero mechanical backlash. A RESOLUTE readhead and RESA rotary ring is installed on each axis providing 20-bit resolution and compatibility with Panasonic servo drives and an ITRI-developed controller. The resulting overall positioning accuracy is ±10 arc seconds and repeatability is ±5 arc seconds with a maximum system angular resolution of 0.001° (3.6 arc seconds). The rotary table (Ø250 mm) generates torque values from 170 Nm to 300 Nm, about the rotation axis, and 245 Nm to 440 Nm about the tilt axis.

For ITRI"s application, the encoder readhead and scales needed to be compact enough to fit inside the motor housing as an integral part of the servo / mechanism. Mr. Chen continues: “In selecting the encoder system, volume was an important consideration which necessitated an ‘open" type encoder as enclosed variants have external housing, increasing bulk, and are generally not suitable for installation in a DDR mechanism. Although machine tool environments are generally contaminated with metal swarf, oil and coolant, enclosing an open encoder within the motor eliminates any related problems. Moreover, RESOLUTE"s high level of ingress protection (IP64) provides further assurance.”

The adage: ‘time is money" is especially true with today"s shorter product-life cycles, product diversification and fierce competition. Manufacturers are in the pursuit of quality products to meet customers" needs while continuing to enhance productivity and efficiency with a view to minimizing the time-to-market (TTM) for new product launches. As Mr. Chen explains: “Rotary table speed can significantly influence production costs; for example: on a large-scale production line, with a daily throughput of tens of thousands of units, any delays would clearly result in increased overall costs. Absolute encoders, in contrast to incremental types, capture position information on demand and can restart after machine stoppages without first homing to a datum, which allows the machine tool axes to simply resume from the same position after tool changes and setups - greatly reducing the overall production time.”

ITRI is committed to the development of new technologies for industry but, as is the case for all leading innovators, the development process inevitably encounters some challenges. Mr. Chen concludes: “We had decided to build a competitive rotary table and in view of the friendly relations, over many years, between ITRI and Panasonic and experience of their products - we opted to use a Panasonic servo-drive but could not find an open absolute encoder on the market that met our specifications while being compatible with Panasonic serial protocols. We contacted Renishaw and they were willing for us to jointly, with Panasonic, develop Panasonic serial protocols for RESOLUTE, which allowed the creation of Panasonic Taiwan"s first direct-drive rotary table. We have a long-standing relationship with Renishaw and find their after-sales support to be excellent; we have also purchased their SiGNUM™ incremental encoder and XL-80 laser interferometer.”
