fanuc ddr rotary table made in china

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.

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.

DD technology for linear motors and rotary tables has matured in recent years. It has significantly improved the overall performance of machine tools, which has enabled corresponding improvements in the quality, speed and efficiency of production machining. These benefits help manufacturers to reduce machining times and to drive down costs.

Haozhi builds direct-drive rotary (DDR) tables and linear motors with integrated high-performance optical encoder systems from Renishaw, which give Haozhi products a substantial competitive advantage. Qun Lei, Vice President of Haozhi, explains his company’s role in the machine tool industry: “Haozhi initially focused on producing machine tool motor spindles and, after many years of hard work, we are now the global market leaders. We have launched a wide range of spindle products aimed at different industries –  including the world’s fastest motor spindle that operates at up to 400 krpm with a rotational accuracy of 6 µm. We also manufacture machine tool rotary tables and linear motors, and are developing gear reducers and robotic joint products to cater for the rapidly growing robotics market. We export primarily to Southeast Asia and a number of European countries.”

General market trends for DDR motors include higher position accuracy, increased reliability, and lower maintenance costs. In recent years, the use of direct-drive rotary (DDR) table technology has expanded into automated manufacturing and light-machining applications.

Rotary tables are usually deployed as either a fourth or fifth axis on CNC machining centres for precision light manufacturing, such as the machining of mobile phone and tablet cases. Alternatively, rotary tables are used in indexing table modules for automated production lines.

Many everyday consumer products require parts that have been precision machined on rotary tables with excellent accuracy and motion control performance in order to produce the smooth surfaces required. The error budget of a motion control system, such as a rotary table, is affected by factors related to the machine structure, individual mechanical components, transmission mechanisms and position encoders.

Mechanical resonance is one of the most common problems designers face when trying to maximize either the command response or dynamic stiffness of traditional rotary tables driven by worm gears. One particular concern is the inertia mismatch between the load and the motor.

DDR tables eliminate many of the mechanical resonances associated with traditional rotary tables and enable the design of high-performance systems which are optimised for the speed and torque requirements of the application.

For Haozhi, encoders are one of the most critical components in their motion control products. Important encoder errors for rotary motors include sub-divisional error (SDE), jitter, installation error (which includes scale eccentricity), scale graduation error and the compliance of the coupling between the motor and the encoder rotary scale.

Renishaw has a significant presence in the machine tool sector and has cultivated a successful relationship with Haozhi over many years. Haozhi has selected the RESOLUTE™ absolute optical encoder series with RESA rings for its new family of rotary tables. “We first came across Renishaw’s advanced metrology products more than a decade ago and have enjoyed working with them ever since. When we decided to begin developing rotary tables, we chose their optical encoders without any hesitation as we have the utmost confidence in Renishaw’s products. Our experience has shown that their optical encoders are easy to install and that our engineers are able to assemble them quickly. Renishaw’s expert team also provides outstanding aftersales service, and they helped with any issues that we encountered during the early development stages of this project.” Mr Lei explains.

Mr Lei continues:“In terms of compatibility and the diversity of the product range – there are definite advantages to Renishaw encoders. Many controller manufacturers out there offer a huge variety of available communications protocols: RESOLUTE absolute optical encoders support most mainstream industrial comms protocols including FANUC, Mitsubishi, Siemens DRIVE-CLiQ and BiSS.Furthermore, the encoder readhead and ring dimensions are always the same irrespective of the serial protocol output option which eliminates the need to modify our structural designs.”

Mr Lei highlights the role of Renishaw laser calibration products in the quality control testing of Haozhi’s linear and rotary stages: “In order to make a good job of quality control, we use Renishaw XL-80 laser interferometers with XR20-W rotary axis calibrators to test all our linear motors and rotary tables. The accuracy, ease of use and reliability of the testing equipment were decisive factors.”

By integrating Renishaw’s RESOLUTE absolute optical encoder system into its CNC rotary tables, Haozhi has further assured the accuracy, reliability and superior motion control performance of its products.

Haozhi rotary tables offer positioning accuracy of ±10 arc seconds, repeatable precision of ±2 arc seconds and a wide range of torques and speeds. While Haozhi linear motors offer a bidirectional positioning accuracy of ±2 µm, a continuous thrust range of 0.2–4.0 kN, and a peak thrust range of 1–12 kN.

Guangzhou Haozhi Industrial Co. Ltd. is a technology company that specializes in the R&D, design, production, manufacturing, sale and maintenance of high-precision mechanical and electrical components. The core of Haozhi’s main business is advanced machine tool spindles, rotary tables and DD linear motors which are integrated into OEM manufacturing equipment and robotics applications. It became a listed company on the Shenzhen Stock Exchange’s Growth Enterprise Market (GEM) in 2016.

Second, my 4th axis is an A-axis. There"s a few parameters to define the direction, which is explained in moderate detail in the attached G54.2 instruction sheet from Fanuc. Cross reference your machine manual to make sure the parameter numbers are the same for you.

A few final notes: I turned look-ahead off and on, as well as added delays, to account for timing issues on my hardware. I use the Fanuc DDR, and the manual warns about requiring this. It needs time to reach the target angle before you can apply the brake. Your hardware may not require all this timing stuff, so you"ll see some noticeable delays with this code.
