hydrostatic rotary table quotation
This is an example of a hydrostatic spindle designed for high speed grinding with CBN grinding wheels. The small bearing diameter in combination with high surface speed allows the use of CBN wheels even for undercuts in a camshaft application.
Rotary transmission leadthroughs serve as a rear inter face for fluid transmission into the spindle. A hydromechanic clamping unit or integrated clamping cylinder can be actuated with the media oil, air and coolant. The transmission of oil and coolant is possible at rotational speed.
• Gleason-Pfauter of Ludwigsburg, Germany built the world’s largest machine for gear grinding. One of the engineering highlights of this machine is the use of a hydrostatic bearing system for the rotating table. This table design makes it possible to very
The high table load and machining forces are not a problem for the hydrostatic bearings. Dampening of the hydrostatic system is 10 to 100 times better than with roller bearings, resulting in better surface quality of the gear. The round table floats – independent of speed – on a number of 20 micron hydrostatic bearing pockets. The end result is a totally wear-resistant system with very high stiffness. The accuracy of the machine can be expected to be unchanged over many years of operation since no wear takes place. With the use of a HYPROSTATIK PM controller system for the oil fl ow, the
hydrostatic pockets are so stiff that a 40 ton gear load will change the bearing gap by only a few microns. The mechanical PM fl ow controller employs a unique and patented design and is manufactured by HYPROSTATIK of Goeppingen, Germany.
The achievable roundness accuracy of the rotating table is much better than that of tables with comparable roller type bearings. At low RPM, friction is virtually nonexistent. In fact, friction is so low that one person can easily move the table with a 40 ton workpiece on it by hand. This low friction allows the table to be positioned second angle movements without backlash or high initial friction. Such slow and accurate positioning is only possible because of the hydrostatic bearing.
The typical oscillating motions used during gear grinding cause wear when using ballscrews. This results in loss of accuracy and can lead to failures over time. When using hydrostatic guide ways and hydrostatic lead screws, oscillating machine motion does not cause wear or loss of accuracy.
In addition, to further reduce friction and wear, hydrostatic bearings from HYPROSTATIK are installed on the table drive worm gear spindle and on the ways for the machine column.
The engineering calculations required for implementing the hydrostatic system were made by HYPROSTATIK. Since the hydrostatic pockets are machined directly into the frame of the machine and the table sits directly on the frame, there is no need for
Hydrostatic systems that improve machine accuracy can also be used on machining centers, grinding machines, lathes, and spindles for rotating tables, guide ways, bearings, and threaded spindles. For more information, contact Transatlantic Connection, Inc. – US Representative for Hyprostatik.
With proper selection and integration of high-performance brushless DC servo motors ABTech’s air bearing rotary tables provide ultra-smooth and precise rotary motion. With high torque, high performance motor drives, our motion experts will gather your specific requirements and work closely with our motor suppliers to create/select a motor drive that suits your specific application. Whether you need sub-micron position accuracy with minimal settle time and stringent following error specifications, high-speed constant motion, or a combination of both there is an ABTech rotary table that will meet your needs.
ABTech’s modular design approach facilitates multiple system configurations to optimize the price-for-performance required in your application. This approach allows the user to define the level of control desired for the most cost-effective solution. Our complete engineering services allow us to respond quickly to provide a solution to your O.E.M. requirements for ultra-precision rotary motion.
ABTech’s standard line of high precision, air-bearing rotary tables (AT Series) and heavy-duty rotary tables (HDRT Series) are ideal for low-speed TIR measurements, optical inspection, precision assembly, or light machining and grinding where radial and axial accuracies down to 2.0 µ” are required. These are available with tilt and center worktables, precision fixtures, 3-jaw chucks, vacuum feed through the center, and motor drives. They are manufactured with 440CSS and hardened to 58 – 60 RC, making these rotary tables the most robust available.
The hydrostatic rotary tables from ZOLLERN impress with their durability and a high concentricity and axial runout accuracy. Thanks to the ZOLLERN bearing clearance compensator, the optimal pocket pressure is set automatically and independently of production tolerances. The freedom from friction at low speeds prevents slip stick and therefore allows maximum positioning accuracy.
American Block offers a complete line of drilling rotary tables that range from 17 ½ to 60 ½ . These tables are designed to withstand the harshest drilling conditions. All rotary tables feature a fabricated frame, heavy duty main thrust bearing and precision machined spiral bevel gear that results in superior strength, toughness and durability.
American Block can also provide unitized rotary table assemblies (IRD). Our unitized skid packages are ideal for new builds or can be retrofitted to existing rigs. Featuring a heavy-duty oilfield skid and an extend life transmission. The rugged design ensures that when the equipment is mounted it remains rigid during operation and rig moves. Other rotary table options include hydraulically operated tables and high torque tables (25% more torque), which are ideally suited for top drive operation.
