TMX160 Heavy Duty Rotary Table with increased rigidity for demanding applications. The internal air hydraulic booster gives extremely high clamping forces.

TUX200 Rotary Table with top mounted motor suitable for horizontal machines. Integrated air booster provides high clamping torque from a standard air supply.

In 2019 the Japanese manufacturer Kitagawa introduced the first in a new range of compact, general purpose rotary tables, the MK-series (www.1mta.com/product/mk-series/), for adding a rigid fourth CNC axis to a 3-axis vertical machining centre. One year later the MK200 has been joined by a second model, the MK250, with significantly uprated performance. Availability in Britain and Ireland is through sole sales agent 1st Machine Tool Accessories, Salisbury.

Most notable improvement on the MK250 is the 1,000 Nm, pneumatically actuated clamping torque, making it more than four-fifths stronger than the first model. As with all Kitagawa tables, this torque is determined by the point at which the force on the worm wheel causes it to displace by 30 microns. In contrast, some manufacturers quote the slipping torque as a maximum, which can cause inaccuracy or even failure.

If a Kitagawa TSR181A tail spindle with integral clamp, also available through 1st MTA, is added for securing a component or tooling column horizontally between centres, clamping torque increases to 1,600 Nm. The result is even faster, heavier duty, more productive machining. As the table has a small footprint, loss of bed area and working volume in a machining centre is minimised.

Kitagawa has both stronger and more compact rotary tables of similar capacity in its product ranges, for example the GT250 and CK250 respectively, but Kitagawa asserts that the MK250 meets 90 per cent of all customer requirements. The unit on its own can support a load of 250 kg horizontally, while it may alternatively be used to hold a component or column weighing up to 125 kg in the vertical orientation. Maximum positioning speed is 33.3 rpm.

The type of the faceplate is specified by the customer, either with T-slots or pre-drilled holes. The advantage is that a chuck, trunnion or other workholding device can be mounted directly onto the rotary table, reducing the distance from the spindle bearing. Such compact assembly lessens the load on the bearing, increasing rigidity and longevity. Cutting torque is 480 Nm and the spindle through-hole diameter is 70 mm.

The table design minimises accumulation of chips around the base, reducing cleaning time and ensuring the absence of interference to the workholding arrangement – an important consideration in automated production cells.

Compact, built-in, 7 MPa rotary joints may be selected from 4-, 5- and (6+1)-port types, the latter having a 12.5 mm diameter, multi-purpose hole through the centre for additional hydraulic or pneumatic services to actuate workholding. The hole can also be used as a duct for cables feeding signals back from fixture sensors confirming correct workpiece seating, enabling the design of the workholding configuration to be improved and its capabilities enhanced.

1st MTA will alternatively provide a high pressure 25 MPa, 4-port or 6-port rotary joint instead of the standard 7 MPa variety, allowing a further reduction in fixtures sizes as well as improved clamping speeds.

Compact built-in rotary joints can be selected from 4-, 5- and (6+1)-port types. The centre port of (6+1)-port type has a φ12.5mm multi-purpose hole for high-pressure coolant, work seating detection sensor, etc.

After adding four-axis or five axis rotary table on the machine tool, multi axis machining can be realized, which can improve the machining efficiency and yield. With the improvement of manufacturing automation in China, the demand for rotary table increases significantly.

China is the world’s processing plant with a large number of CNC. For example, Foxconn has more than 200000 CNC, BYD, Lens, Luxshare and Some companies more than 100000sts, and there are no less than 1000 companies with more than 1000 CNC. All major brands want to occupy their own market in China.

Now, I will introduce the situation of several rotary table brands in China. We will divide them into four categories: Europe andAmerica, Japan, Taiwan and Chinese brands.

Japan: Fanuc, Nikken, Tsudakoma, Kitagawa and Sankyo are major brands. They are mainly configured on machine tools of some Japanese brands. Some factories will also be equipped with them  when machining precision parts. Fanuc has the largest market share with, because robodrill is most widely used in 3C industry in china, so many factories are equipped with its DDR

Taiwan: TJR, Detron and GSA are the main brands, as well as DEX, Autocam and HW. These rotary tables are not only configured on Chinese brand machine tools, but also sold to end customers. Their precision is not high and their service life is not long, but they can meet the requirements when machining parts with low precision. Some users will consider these brands when their budget is limited. Among these brands, TJR has the best sales volume, with an annual sales volume of more than 10000 sets, because they have the most complete distribution network, complete models and cheap prices.Most importantl

China: there are many locally four-axis brands in China, such as Gutia,Silvercnc, Blue tech, CP and Deshu. The product quality of these brands is comparable to that of Taiwan. Due to more favorable prices and fast delivery, they have occupied the market of most Taiwan brands. The four axis of Chinese brands mainly adopt roller cam structure or harmonic structure. The wear resistance of roller cam is better than that of worm gear, with long service life and good accuracy retention. The price of harmonic reducer rotary table is low, which is suitable for 3C industry. These two structures meet the needs of the market and have been recognized by customers.

I have an Cincinnati Arrow. Years ago I bought a Kitagawa rotary off EBay, rotary model TB160 as I recall. The rotary has its own control box. However the machine is pre-wired for another drive.

Kitagawa Europe are putting all their technical teams from the United Kingdom, Germany, and India together under one banner called the Application Research Group or ARG for short.

Currently, the Application Research Group consists of individuals who have extensive experience in using all our work holding products before focusing on certain products, be it rotary tables, steady rests, power chucks, etc.
