YMT Technologies have been working with RMA Precision to install two Detron GFA series of 5-axis rotary tables. Read on to hear what we had to say about the upgrades and what is now achievable!
The Detron GFA series of 5-axis rotary tables from YMT Technologies set new standards in build quality, accuracy and flexibility. Critical faces within the rotary tables are ground rather than just turned for indexing accuracy and concentrically. Engineers can also increase productivity with larger cuts and benefit from smooth braking without deformation of the table surface during braking. Detron?s patented dual piston clamping technology and a fully enclosed brake drum ring operating at high pressure makes this possible.
Jason Short, Tooling & Workholding Manager at YMT Technologies says, ?The GFA series of tables delivers a small footprint allowing more and larger parts to be manufactured and, the large centre bore and height of the centre line add to the flexibility of the unit. We are finding that the most popular model is the Detron GFA-210S which is perfect for most applications. Repeatability and accuracy are important to the customer and the GFA 210S has a resolution of .001 degrees and repeatability of 6-8 seconds, thanks to its high precision cross roller bearings and, tested with 5 continuous clockwise and counter clockwise rotations, it meets ISO 230-2 standards.?
Integrated radial and axial bearings, where the spindle and bearing is one unit, add to the rigidity of the rotary table. Additionally, the dual lead worm itself uses large tooth depth resulting in a contact surface 1/3 greater than conventional worms. To ensure long service life, reliability and thermal stability, the worm is positioned at the bottom, so that it is totally immersed in oil. Jason Short adds, ?All these design features add to the quality and reliability of the Detron GFA series rotary tables and make them ideal for heavy 5-axis
YMT?s experience with rotary tables and machine controls enables it to ensure that the Detron unit is properly interfaced to the customer?s machine tool. Its engineers have the skills to set parameters and install the necessary connections and cards. The motors on the Detron GFA series are control specific, so YMT tests the installation in house before delivering it to the customer for maximum reliability and straightforward commissioning.
As well as the rotary table itself, YMT is able to supply full turnkey systems with technical advice, a range of vices and fixtures as well as automation. In fact all the Detron GFA series rotary tables have ports in the table so that they are automation ready, giving a clear upgrade path for engineers.
