Once that"s achieved, I believe the worm-and-eccentric assembly can be slid into the table base casting. My guess is that the worm and wormwheel teeth will interfere with each other unless the eccentric is clocked within the table base so that the worm is as far away from the wormwheel as the eccentric will allow.
When the eccentric is seated within its bore, and clocked so that the worm clears the wormwheel, the table top can be rotated by hand, but not by the worn.
At that point, you"ll want to rotate the eccentric to move the worm toward the wormwheel. The worm and wormwheel teeth can engage only when one gear"s teeth can fit between the other gear"s teeth. This means that you"ll need to rotate either the worm or tabletop (and thus the wormwheel) while rotating the eccentric. Once the teeth start to engage. Continue rotating the eccentric until the teeth bottom, and then back off a touch.
At this point, you"ll want to put the wormshaft graduated collar and crank handle back on. Then turn the crank until you either find a tightening of the gears (at which point, use the eccentric to gain a bit of clearance between the worm and wormwheel, OR the table top rotates a full turn without perceptible binding.
Worm and wormwheel lubrication? I"ve worked with rotary tables that are oil lubricated, and ones that are grease lubricated. I don"t know if your Phase II table is supposed to be oiled or greased, but in either case, it"s a good idea to lubricate the bearings and gears with an appropriate lubricant before assembly.
In addition, since rotary motion is often performed for the purpose of processing, measurement, or some other subsequent operation, the use of rotary tables by themselves is rare.
Rotation mechanisms used in chairs and other equipment are also classified as rotary stages in the broad sense of the term, so they are used not only in manufacturing but also in home applications.
A crossed roller bearing is a bearing structure in which rollers are arranged between the inner and outer rings. The rollers are arranged in a straight row with a 45° contact angle, enabling the back bearing structure of a ball bearing to be realized with a single row, and the structure is capable of receiving loads from multiple directions simultaneously. The rotary table and cross roller bearings can be directly connected, which reduces the number of structural parts.
Since the rotational accuracy of the rotary table is directly related to the accuracy of the rollers, high rotational accuracy can be obtained depending on the accuracy grade of the rollers. In addition, since cross roller bearings have low frictional force and can be operated with light force, micrometer heads can be used in the fine-tuning rotation mechanism to obtain high positioning accuracy.
Many rotary table manufacturers outsource gear fabrication to lower costs. While that strategy may offer short term cost savings, Index Design’s American made rotary tables are built with gears cut in house. This is the only way to closely monitor and control tolerances, consistency and performance.
Our rotary tables incorporate large diameter high tensile bronze worm gears mated against hardened steel drive shafts. The combination of metal gives superior wear properties for long lasting operation. As the rotary table is run, the properties of a tin bronze gear develops a low friction deposit on the mating steel drive shaft. These deposits fill in microscopic pores of the mating surface. Over time, as these deposits are embedded on the surface, wear decreases followed by a reduction in frictional forces within the gear assembly.
In addition, the data gathered from our automated calibration procedure allow our engineers to assess, monitor and improve the static and dynamic performance of prototype rotary tables during the design phase.
Our engineers have a long and rich history in the machine tool business, they combine decades of both CNC machine tool and rotary table manufacturing experience with the latest design tools to produce rotary tables with superior performance and dependability.
Our CAD/CAM software is used to analyze displacement and stress for each component, sub-assembly and total assembly. However, the best software and technology is worth next to nothing if no one understands the craftsmanship. This is particularly true when manufacturing precision rotary tables which involves many steps. Despite all the modernization and automation available, a large part of the manufacturing process is still completed by hand. At Index Designs, we understand and appreciate craftsmanship, It is designed and built into our products.
I have a similar PhaseII, although it"s a vertical-horizontal model. The "black thingy" does indeed rotate about a half turn to engage or disengage the worm. It should work very smoothly if your table is in good shape, although sometimes a slight turn of the wheel (front part of the black thingy) is needed to engage the gear. However, it appears to be part of the PhaseII experience that the engagement, which is very finely fitted, is easily damaged if the table is dropped or the "black thingy" bangs into something. The manual specifically warns of this.
Unfortunately I banged my table, and it promptly locked up much as you describe. I managed to disassemble it --- there is a link in this forum to an old post of mine detailing exactly how to do this --- and found that a very small bump --- so small I was able to work it out with an extra fine jeweler"s file and some 800 grit emery paper --- was enough to lock the rotating eccentric which effects the worm engagement.
If you are not able to easily and smoothly engage the worm, it is very possible that the eccentric is damaged in the manner I described. Search this forum for my name and phaseII and you will find a post with an exploded-parts diagram, and a later post with disassembly info. Sorry I don"t have it at hand to attach to this post.

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.
2.roller cam: This is the most popular deceleration mode in the Chinese market. Compared with worm gear, it has many advantages, such as wear resistance, high transmission efficiency , good price and basically no maintenance. Chinese consumers like it very much.
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.

CNC rotary tables play a vital role in the performance of multi-axis machining centres. As table accuracy and reliability are of paramount concern throughout the product"s lifetime, Matsumoto Machine Corporation (MMK) has taken a pragmatic two-pronged approach to reducing indexing errors and improving performance. By enhancing both product calibration and encoder technologies the company has set new standards for rotary table accuracy.
Founded in Japan in 1948, Matsumoto Machine Corporation is a technology-leading provider of innovative, high quality jaw chucks and numerically controlled rotary tables used by industrial machine tool makers throughout the world. A key feature of MMK"s CNC rotary tables is a patented worm and wheel gear assembly developed by OTT GmbH, Germany. Unlike double lead worm gears, the OTT worm and wheel gear is able to minimise backlash, ensuring outstanding accuracy and long life, efficiency and durability.
Shaped in order to maximise gear surface contact area, thereby reducing adverse surface pressure effects, the OTT worm gear teeth are split into separate right and left parts (shank worm and hollow worm) connected by a span ring. This unique structure enables backlash adjustment simply by reducing the distance between the two parts. This design also ensures that only one side of a worm gear tooth is in contact with the wheel gear, leaving a clearance on the other side. As a result, the 2-piece split gear design will not seize up, even with zero backlash.
A further advantageous characteristic of the MMK CNC rotary table is a large diameter through-hole in the table spindle. This greatly increases machine versatility and rigidity, supporting a wider variety of chucks and jigs and the machining of longer workpieces.
By enabling most metal-machining operations to be undertaken on a single machine, the benefits of MMK CNC rotary table are far-reaching. These include the time and cost saving of single machine set-up and single fixturing setup, reduced parts handling and the elimination of tolerance errors as workpieces pass from machine to machine.
Of critical importance in this one-hit machining centre scenario is ensuring the high accuracy of CNC rotary table indexing and control throughout its working lifetime.
As with a machine tool"s linear XYZ axes, the rotary axis is just as susceptible to uncontrollable events that may introduce angular positioning or axis alignment errors. Risking the production of defects in finished parts, these errors can be due to a number of reasons including, mistakes made in the initial machine installation, impact damage caused by collision or general wear-and-tear in use.
With its global reputation for product quality and design innovation, MMK therefore sought to equip its CNC rotary tables with a highly accurate and reliable means of tracking and controlling the indexing of its product throughout its lifetime, irrespective of the type of machine tool, workpiece complexity and duty cycle.
At the same time, in an increasingly competitive global market for CNC rotary tables, MMK also wanted to further enhance its product quality inspection processes. Specifically, the company set itself the task of augmenting index angle measurement as a key component of pre-shipment quality assurance procedures.
To provide machine tool makers and users with the ability to accurately track and control CNC rotary table indexing, MMK elected to integrate Renishaw"s super-compact TONiC™ non-contact optical incremental encoder system. Simple to install and with a compact readhead measuring just 35 mm x 13.5 mm x 10 mm, the TONiC encoder presented MMK with a minimal footprint solution capable of supporting machine speeds up to 10 m/s and resolutions down to 1 nm.
The rotary table readhead was designed to be used in conjunction with Renishaw"s RESM, a one-piece stainless steel ring marked on its periphery with 20 µm pitch graduations and featuring the IN-TRAC™ optical reference mark. With its low profile, large internal diameter and wide choice of diameters from 52 mm to 550 mm, the high stability RESM ring provided MMK with a versatile and easy to integrate scale that is well-suited to the company"s wide range of CNC rotary tables.
MMK selected Renishaw"s compact and lightweight XR20-W rotary axis calibrator to verify the accuracy of its rotary tables during manufacturing and immediately prior to shipment. The XR20-W was used in conjunction with Renishaw"s XL-80 laser interferometer to provide a non-contact reference measurement, independent of the axis under test, with an accuracy of ±1 arc second.
Motorised by a servo-controlled drive and with data capture synchronised to axis movement, the XR20-W requires no operator intervention during measurement. Being lithium battery powered and Bluetooth enabled, it ensures quick and easy setup, and the avoidance of trailing cable hazards. The calibrator"s modular design and flexible mounting systems allow far easier setup than alternative solutions and can be readily configured for a wide variety of rotary tables, chucks and spindles.
By integrating Renishaw"s TONiC non-contact optical encoder system into its CNC rotary tables, MMK has further assured the accuracy and reliability of its products in the field, along with an overall superior motion control performance. For a wide range of different machine tools and end uses, the rotary tables" combination of compact readhead and one-piece stainless steel ring scale has delivered a higher level of tolerance to dust, scratches, grease and oil, and a reduction in indexing errors. The encoder system"s ability to output highly stable position signals of unrivalled purity and ultra-low sub-divisional error have provided smoother velocity control, improved scanning performance and increased positional stability.
MMK"s introduction of Renishaw"s XR20-W rotary axis calibrator and XL-80 laser interferometer has reduced product measurement times by a half compared to conventional autocollimator techniques. Measurement procedures have been simplified and automated. Capable of taking accurate measurements at any indexing angle pitch, the calibrator enables evaluation of the accuracy of the worm and wheel gear-driven table for ultra-fine pitch measurement movements as small as 0.001°. This has allowed any loss of motion control or worm and wheel gear efficiency to be evaluated in detail and addressed. Product performance is now backed by a thorough analysis meeting ISO quality standards.
