cheap rotary table factory

The reverse rotary table is perfect for using on the tilting angle table. The reverse mount allows access to the handwheel from the front of the machine (see photo below). If you used a standard rotary table in the previously described set-up, the handwheel would be mounted facing the backside of the X-axis.

NOTE: When the worm housing is reversed to the opposite side, a clockwise rotation of the handwheel or stepper motor will result in a counter-clockwise rotation of the rotary table.

The rotary tables can hold more weight when they are not under a continual load. Click on the Video tab above to see examples of different weights and uses for our rotary tables.

A rotary table is a really nice accessory to have for your mill, but one that you can delay purchasing for a while until you master the basic milling operations. The rotary table is driven by a worm-gear and is accurately calibrated in degrees and fractions of a degree.

Finding a rotary table of the right size for the mini-mill has been a lille problematic. 8-inch tables are really much too big. Even a 6-inch is pushing the limits. I have one from Grizzly. It is well made and works well, but mounting it to the table was a little bit of a challenge.

The first rotary table I purchased was made in India and was of really poor quality. I returned it to the vendor for a refund. Unfortunately, the return shipping on a heavy object like this is not cheap, so be careful what you buy!

Sherline makes a beautifully finished 4″ rotary table which I got to see first hand at Cabin Fever 2001. I was very impressed by the high quality of this item, but It was a little small for my needs.

The table I currently use is a Grizzly G1049 6-inch model. As of 03/02 it sells for $199 plus shipping. It is well-made, and I have been very satisfied with it, although it is a little large for the mini-lathe as you will see in the photos below.

After cleaning off the packing grease with kerosene, a painbrush and a rag, I mounted it on the mini-mill table using 3/8″ carriage bolts that I also use for my 3 1/2″ Grizzly milling vise. The center hole is a #2 Morse taper.

The RT is really a little oversize for the mini-mill, but still provides enough clearance to be practical. I did not feel that the weight was beyond the capabilities of the mini-mill table.

Here’s a picture showing the table with a 12″ rule and a 1/2″ mill in an end mill adaptor. Mounting the mill in a collet would provide another 2″ or so of working room. The head is at the top of the column. Also shown is the 3″ chuck from the 7×10 mini lathe. As you can see, there is adequate clearance for most operations.

The casting has mounting lugs for both horizontal or vertical mounting. This makes it potentially much more flexlible, but the table of the mini mill is small compared to the RT which makes mounting the rotary table in the vertical orientation a little tricky.

One problem is that the lower edge of the handwheel for the RT is lower than the base of the RT, so it must be positioned off the edge of the table. If the RT is positioned perpendicular to the X-axis, the mounting holes in the RT are outside the limits of the T-slots in the mill table.

For the price, I was pretty impressed by the quality of the table. I would rate it somewhat lower in quality than the Sherline 4″, but much better than the Victor 6″.

The handwheel is satin-finish steel with cleanly etched divisions. Each full rotation of the handwheel rotates the table by 4 degrees. A brochure included with the RT illustrates an indexing plate accessory which can apparently be attached to the RT, but I’m not sure whether or not Grizzly sells this accessory.

An eccentric cam between the handwheel and the table permits you adjust the meshing of the worm-screw to minimize backlash. A screw with a T-handle locks the cam in place once it is set.

Here’s a nice little 4″ imported rotary table offered by LMS for $134.95. They offer several other models, including the Sherline 4″. I don’t have any first-hand experience with this one, so I can’t really comment on quality or capabilities.

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.

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.

The 200RT Series Rotary Tables are designed for precise motor-driven rotary positioning and indexing. These tables are designed to function independently or in conjunction with linear tables used for precision automation applications. Their low profile design minimizes stack height in multi-axis configurations and enables them to fit in many places where other motorized rotary devices cannot. Models are available in 5, 6, 8, 10, or 12 inch diameters and are offered with four gear ratios making it convenient to match size, speed, and load requirements. They can be selected in either English or metric mounting. They are found in virtually all industries where intermittent part indexing, part scanning, skew adjustment, or precise angular alignment is required. At the heart of these tables is a rugged main support bearing which is comprised of two preloaded angular contact bearing races. It is designed for high load capacity and smooth, flat rotary motion. The drive is a precision worm gear assembly which is preloaded to remove backlash. The top and base are constructed of high quality aluminum with an attractive black anodized finish. The top and bottom mounting surfaces are precision ground to assure flatness.

CNC Indexing & Feeding Technologies offers a wide range of TJR rotary tables. However, many are unclear about what rotary tables can do for their business, as well as how they work in CNC machining. First, let’s consider the basics about a rotary table and how it works in the machining and manufacturing processes.

A rotary table can tilt and rotate. The table makes use of the indexing head in order to cut according to a specific technique. This makes it possible for the machine to create a workpiece with complete flexibility in rotation and angling.

A rotary table can help to create arcs and circles, an important process in part or tool fabrication. Tools can be specially made, such as car parts, machine parts, and many other objects.

The CNC process lets companies make straight cuts even with multiple angles and to cut small objects into even smaller parts. CNC rotary tables can also help in the processes of cutting gears, drilling or cutting holes.

The table can also be used along with a dividing head and index plate, to further concentrate the shaping. Tables are also used to hold certain parts for superior milling techniques.

Adding rotary tables will improve your capacity to produce the parts you want and increase profits. This brings us to the primary advantage of CNC rotary tables: less time and greater accuracy in cutting.

The benefits of using cnc rotary tables include consistency, faster production and increased capacity. Products and work pieces assembled through CNC systems are more reliable than products created manually or through other methods. The process is identical each and every time, so consistency can be guaranteed. This is critical for a company trying to ensure safety protocol.

The capacity of complexity of product is another benefit. Complex motions are made simpler by CNC rotary tables, making them more affordable to produce.

Naturally, such an intricate process cannot be unsupervised, since efficiency depends on optimal performance. A supervisor must oversee a rotary table operating with CNC controls to ensure the machine and software are configured correctly.
