servo rotary table made in china

Rotary table in market mainly includes 4 kinds of mechanism that is worm gear, roller cam, DD driver and harmonic structure. The following is the introduction:

1. worm gear: it’s one of  the most popular structrue in NC rotary table  because of its irreversibility and costs.The worm is generally made of bronze, but the wear resistance is poor. In order to improve the service life, some manufacturers use the alloy steel.

3.DD motor: it’s the most efficient rotary table with the highest precision. It has the highest precision because it has no mechanical structure, which is directly driven by motor , no reducer. It has high technical difficulty and high price. It is generally used for five axis machine tools.

The rotary table is an accessory for the CNC floor type boring and milling machine. It can be working together with the floor type boring milling machine for milling angle, reverse boring, polyhedral machining, and other complex machining processes. It could do five sides machining if the main machine equipped the angle milling head.

CNC rotary table is a common part of CNC milling machine, often used as a servo axis of CNC milling machine, namely C axis of vertical CNC milling machine and B axis of horizontal CNC milling machine. The CNC rotary table includes the foot of the turntable, a round turntable surface, four rolling bearing parts arranged on the upper surface of the foot of the turntable, and a center with a self-aligning bearing installed at the center of the upper surface of the foot of the turntable. Support, each rolling bearing component includes a rolling bearing and a support that supports the rolling bearing through the axle. The center of the lower surface of the turntable is provided with a vertical downward axle. The turntable is installed on the foot of the turntable. The inner ring of the self-aligning bearing is fixed, and the rotating surface of the rolling bearing is in rolling contact with the lower surface of the turntable surface.

The CNC rotary table has an inclinometer with two orthogonal test axes as the test tool. The inclinometer is set at the center of the turntable surface to be leveled, so that the two orthogonal test axes of the inclinometer are parallel to the turntable surface, by adjusting the milling machine turntable. The leveling mechanism under the base makes the tilt angle value output by the two test shafts of the inclinometer turntable in the leveling state.

CNC rotary table and swing head are the key components of multi-coordinate CNC machine tools. Traditional rotary tables and swing heads using high-precision worm gears and other transmissions are not only difficult to manufacture, costly, but also difficult to achieve the speed and accuracy required for high-speed machining. Therefore, it is necessary to develop a new electromagnetic drive system for the CNC milling machine turntable and swing head in a different way to realize the zero-drive drive of the rotational motion coordinates of the CNC machine tool.

1. The CNC turntable uses modular design technology. The PAN turntable and TILT turntable are independent components, which are easy to disassemble and can be controlled by linkage or individually.

2. The use of AC servo motor drives the harmonic wave reducer transmission system to ensure that the equipment not only runs stably at low speeds, but also has fast dynamic response performance.

A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical) axis. Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates that enable regular work positioning at divisions for which indexing plates are not available. A rotary fixture used in this fashion is more appropriately called a dividing head (indexing head).

The table shown is a manually operated type. Powered tables under the control of CNC machines are now available, and provide a fourth axis to CNC milling machines. Rotary tables are made with a solid base, which has provision for clamping onto another table or fixture. The actual table is a precision-machined disc to which the work piece is clamped (T slots are generally provided for this purpose). This disc can rotate freely, for indexing, or under the control of a worm (handwheel), with the worm wheel portion being made part of the actual table. High precision tables are driven by backlash compensating duplex worms.

The ratio between worm and table is generally 40:1, 72:1 or 90:1 but may be any ratio that can be easily divided exactly into 360°. This is for ease of use when indexing plates are available. A graduated dial and, often, a vernier scale enable the operator to position the table, and thus the work affixed to it with great accuracy.

Rotary tables are most commonly mounted "flat", with the table rotating around a vertical axis, in the same plane as the cutter of a vertical milling machine. An alternate setup is to mount the rotary table on its end (or mount it "flat" on a 90° angle plate), so that it rotates about a horizontal axis. In this configuration a tailstock can also be used, thus holding the workpiece "between centers."

With the table mounted on a secondary table, the workpiece is accurately centered on the rotary table"s axis, which in turn is centered on the cutting tool"s axis. All three axes are thus coaxial. From this point, the secondary table can be offset in either the X or Y direction to set the cutter the desired distance from the workpiece"s center. This allows concentric machining operations on the workpiece. Placing the workpiece eccentrically a set distance from the center permits more complex curves to be cut. As with other setups on a vertical mill, the milling operation can be either drilling a series of concentric, and possibly equidistant holes, or face or end milling either circular or semicircular shapes and contours.

* With the addition of a compound table on top of the rotary table, the user can move the center of rotation to anywhere on the part being cut. This enables an arc to be cut at any place on the part.

Additionally, if converted to stepper motor operation, with a CNC milling machine and a tailstock, a rotary table allows many parts to be made on a mill that otherwise would require a lathe.

The stage includes an optical rotary encoder with a digital TTL output signal. After 400x interpolation, the resolution of one encoder count = 0.07 arc-sec (0.33 µrad). Very fine encoder resolution is necessary to enable smooth velocity control by the servo system.

Of utmost importance to this application was the very low error motion of the air bearing. Measurements were taken using a master ball and a capacitance probe. The master ball was mounted 50mm above the air bearing tabletop. Total radial runout error motion measured was less than +/-25 nanometers.
