Rotary tables are an essential component in many manufacturing applications. They provide a precise means of rotating a workpiece allowing for multi-surface machining operations. Among the many rotary tables available on the market today, the MK Series Rotary Tables stand out for their precision, durability, and versatility.
The MK Series is an intelligent design to meet the future requirements that the industry demands from a 4th axis rotary table. Kitagawa’s focus has been to improve the standard of their rotary tables in three areas:
By incorporating friction-welding procedures into the manufacturing techniques and combining this skill with the design capabilities of Kitagawa. We are able to deliver a performance-balanced new standard of rotary table for the future market. Of course, it must be mentioned that Kitagawa India has other stronger (GT Series) and more compact (CK Series) rotary tables in their product range, but the MK Series is designed to meet 90% of customer’s needs. In the majority of cases will be suitably strong enough to withstand various machine cutting conditions demanded of it.
The clamping torque of the MK200 has improved by 40% to 570N.m from the older standard of 350N.m of the MR200 rotary table. Up to 1000N.m for the MK250 compared to 600N.m for the MR250 Rotary Table. To complete the series the MK350 has a massive static clamping torque of 6000N.m and a high cutting torque of 1400Nm which is over double of any of our previous rotary tables and without increasing the center height or the footprint of the rotary table!
After rigorous testing, the MK Series adheres to the same standard of clamping torque test required of all Kitagawa India rotary tables. For example, the MK200 with a 570N.m of clamping torque is determined as the force at which 30 microns displacement of the worm wheel diameter occurs.
Kitagawa determines displacement above this to be a failure as the accuracy you demand from Kitagawa India cannot be maintained. This is markedly different from many of our competitors who use the ‘pull-out torque’ or the slipping torque figure to determine their maximum torque.
Kitagawa views slipping torque as a catastrophic and dangerous failure if you have pushed a rotary table to this extreme. So, you can rest assured that even if you push your Kitagawa rotary table to its limitations of the clamping torque indicated in the instruction manual, your Kitagawa table will maintain its accuracy where others fail. This increase to the standard clamp torque significantly increases the allowable cutting torque your machine is able to deliver to the workpiece, reducing takt time to increase your productivity. The MK Series also maintains the highest rotating/drive torque capability in its size and class of rotary tables. Its large worm wheel diameter design enables you to produce complex workpieces with speed and accuracy.
You will notice that the MK Series Kitagawa rotary tables are supplied without a standard faceplate which will allow you to specify exactly what type of face plate you require – with t-slots or standard pre-drilled holes like the current MR Series rotary tables. The major advantage of this is that a chuck, trunnion bed or any workholding device can be mounted directly onto the rotary table’s spindle, reducing the distance from the spindle bearing. This compact assembly reduces the loading to the spindle bearing, therefore increasing the rigidity and longevity of the rotary table.
The recessed bolt mounting design is a considerable improvement to reduce the overall footprint of the MK Series compared to its predecessor, the MR Series. We all know that space on a machine tool bed can be extremely competitive and adding a rotary table is a big consideration. Anything that can make a rotary table take up less space to allow for more or larger workpieces to be included in the overall workholding design is an important factor when selecting your rotary table.
The recessed bolt mounting allows you to mount any riser block from the top instead of from underneath maintaining the reduced footprint. The MK Series overall thinner design and recessed mounting gives up to a 40% reduction in footprint size. This design also reduces chip build-up around the base of the rotary table, reducing time for any cleaning cycles and ensuring no workholding system interference caused by the build-up of chips. This is a very important consideration for fully automated production cells.
With selectable reduction ratios and servo motors available for the MK series, this allows for more workholding on a trunnion bed arrangement to be actuated via a rotary joint housed within the spindle bore of the rotary table. A rotary joint avoids interference issues you can encounter with tubing and wear if you have to bring the workholding actuation forward of the rotary table face.
There are now multiple options of rotary joint available to the MK series. All the standard rotary joints feature a central multi-purpose through hole for additional air or hydraulic services. It can also be used as a wiring duct for seating confirmation sensors, enabling you to enhance any workholding designs and further increasing your workholding capabilities. The MK200 & MK250 can be provided with a 6-port pneumatic/hydraulic rotary joint however the MK350 rotary joint has up to 16 pneumatic/hydraulic ports. Kitagawa India can also provide high-pressure 25 MPa rotary joints upon request, this will enable you to further reduce fixtures sizes and improve clamp speeds if your design requires it.
One of the key features of the MK Series Rotary Tables is their precision. They are designed with high-precision bearings that ensure smooth and accurate rotation, with minimal backlash or runout. This precision is critical in applications where tight tolerances are required, such as in the aerospace, automotive, and medical industries. The tables are also designed with features that enhance their durability and longevity. For example, they are equipped with a sealed bearing system that prevents dust and debris from entering the mechanism, reducing wear and prolonging the life of the table.
The tables also offer a range of customization options, such as different motor and drive configurations, to suit the specific needs of different applications. This flexibility makes the MK Series Rotary Tables a popular choice for manufacturers.
In summary, the MK Series Rotary Tables are a reliable and versatile choice for precision machining operations. With their high-precision bearings, durable construction, and versatile configurations, they can handle even the most demanding machining applications with ease. Whether you are in the aerospace, automotive, medical, or any other industry that requires precise and reliable machining, the MK Series Kitagawa rotary Tables are an excellent choice.
