detron rotary table brands

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.

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.

In its production facility, complex parts are machined to high accuracy on a Mazak VCN 530C vertical machining centre and through the addition of a 2-axis CNC rotary table from Switzerland-based Peter Lehmann AG, the company can machine parts on five sides using five axes.

The company has enjoyed a close business relationship with Mazak since 1979 so not surprisingly Loesch"s ground floor houses six Mazak CNC machines – the latest being a 3-axis VCN 530C VMC. Following the purchase, a CNC rotary table combination from Peter Lehmann was added to the set-up to enable 5-axis machining.

However, a true 5-axis machine wasn’t an option for Michael Loesch: “Rocker-mounted rotary tables are usually pretty small – but the alternative was to spend a lot more money on a larger machining centre,” he reveals.

A 3+2-axis approach is less expensive while offering a greater flexibility: “For us the Mazak VCN extended by the Lehmann rotary/tilting table is the perfect solution,” Mr Loesch enthuses. “It even leaves enough room to accommodate two more vices on the machine table, thus providing further clamping options for simpler workpieces.”

To the Loesch team, the 1,300 x 550mm table was of particular importance as it can accommodate the Lehmann CNC rotary table and still provide enough space for two (125mm) vices.

Supported by the Swiss rotary table specialist and German sales and service partner IVO Oesterle, the team selected the T1-510520.RR TOP2 2-axis model. “The Swiss quality won us over from the start,” Mr Loesch recalls. “With regard to performance and suitability for digitalisation and Industry 4.0, we simply didn’t need to consider any alternatives.”

3D CAD data of the CNC rotary table was submitted to the team beforehand, so a matching workspace concept could be established via the in-house CAD system.

The 2-axis Lehmann T1-510520.RR TOP2 rotary table is 711mm long, 301mm wide and 250mm high. It clamps workpieces of up to 340mm in diameter which is more than enough for Loesch which mainly processes small to medium-sized workpieces up to cube edge dimensions of around 150mm.

In practice the high positioning speed of the rotary/tilting table is another significant benefit: “If possible we use one single tool, e.g. a chamfer milling cutter, to execute all operations in sequence, turning and tilting the workpiece than repeatedly changing the tool.”

“This required up-front collaboration between Lehmann and the Mazak control system developers but the result was well worth the effort. I can now program our VCN 530C with its 2-axis rotary table just like a 5-axis Mazak Variaxis which reduces programming to a fraction of the time. The productivity gains are significant – particularly for single and small-series parts. Typical batch sizes for us about between 20 and 200 pieces.”

Michael Loesch is very satisfied with his investment: “Thanks to the Mazak VCN 530C, the Lehmann rotary table and the other options we specified, we have made considerable time savings and reduced the effort required for re-clamping, thereby freeing up our machine operators to take care of other tasks,” he states.

Next on the agenda is an automated system to feed the VCN, but the Lehmann rotary table is already ahead of the game because it offers media channels to facilitate the remote control of automatic clamping systems.

“The force clamp on the rotary table is already pneumatically controlled and the two vices on the machine table will then be converted from manual to hydro-pneumatic operation,” Mr Loesch concludes. “This will allow us to fully machine all six sides without any manual intervention. This is definitely the way forward for us.”

Are you looking for an accessory to boost the precision of your modern machining centers? CNC rotary tables provide a versatile tool in expanding the capabilities of your machines. They allow for precision positioning during 4 and even 5 axis cutting operations, thereby transforming 3-axis machinery into CNC machines with heightened accuracy. CNC rotary tables are a cost-effective solution to perform complicated machining tasks, with additional benefits such as increased productivity, efficient use of labor and materials, and better quality control.

Additionally, CNC rotary tables can be used independently to mount other components on a table, including trim attachments and chucks for drilling applications. CNC rotary tables offer considerable advantages that promote their usefulness in a variety of industrial settings.

The 3 1/2 axis machines will require a PLC on the rotary table. The index command is done with an M code that tells the output to do something. The PLC then moves the rotary. Great for hole drilling or milling slots, but not much else.

2. We"ve got about every brand of rotary table. The only one that I can say to stay away from is MECA. We have Fadals, Haas, and Troyke in production. The Troykes are tilting tables with manual tilt and NC rotate.

3. If your machine is 4th axis ready, you will have to get a motor that is compatable to the machine. These can be AC or DC and equipted with encoders or resolvers. I just had to switch a Troyke over to another machine. The motor and cable were $1,500. They want $12,000 for a new table!

The Detron GFA series of five-axis rotary tables from UK-based YMT Technologies is said to set new standards in build quality, flexibility and accuracy.

According to YMT Technologies, the critical faces within the rotary tables are ground rather than turned for indexing accuracy and concentricity. Users can increase productivity with larger cuts and benefit from smooth braking without deforming the table surface during braking thanks to its patented dual-piston clamping technology and a fully enclosed brake drum ring operating at high pressure.

The company notes that the GFA series of tables delivers a small footprint, allowing more and larger parts to be manufactured, while the large centre bore and height of the centre line add to the flexibility of the unit. The most popular model is the GFA210S, which is good for most applications. With repeatability and accuracy being important, GFA 210S has a resolution of 0.001° and repeatability of 6-8 seconds thanks to its high-precision cross roller bearings. It has been tested with five continuous clockwise and counter-clockwise rotations to meet ISO 230-2 standards as well.

Moreover, the dual lead worm uses large tooth depth, resulting in 33% greater contact surface 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. These design features make the Detron GFA series ideal for heavy five-axis, cutting operations. Backed by the company"s experience with rotary tables and machine controls, the Detron unit is properly interfaced to the customer’s machine tool. Here, parameters are set and the necessary connections and cards are installed. The motors are control-specific, so YMT tests the installation in-house before delivery to ensure maximum reliability and straightforward commissioning.

YMT also supplies full turnkey systems with technical advice, a range of vices and fixtures as well as automation. The Detron GFA series rotary tables have ports in the table so they are automation-ready.

A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical) axis. Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates that enable regular work positioning at divisions for which indexing plates are not available. A rotary fixture used in this fashion is more appropriately called a dividing head (indexing head).

The table shown is a manually operated type. Powered tables under the control of CNC machines are now available, and provide a fourth axis to CNC milling machines. Rotary tables are made with a solid base, which has provision for clamping onto another table or fixture. The actual table is a precision-machined disc to which the work piece is clamped (T slots are generally provided for this purpose). This disc can rotate freely, for indexing, or under the control of a worm (handwheel), with the worm wheel portion being made part of the actual table. High precision tables are driven by backlash compensating duplex worms.

The ratio between worm and table is generally 40:1, 72:1 or 90:1 but may be any ratio that can be easily divided exactly into 360°. This is for ease of use when indexing plates are available. A graduated dial and, often, a vernier scale enable the operator to position the table, and thus the work affixed to it with great accuracy.

Rotary tables are most commonly mounted "flat", with the table rotating around a vertical axis, in the same plane as the cutter of a vertical milling machine. An alternate setup is to mount the rotary table on its end (or mount it "flat" on a 90° angle plate), so that it rotates about a horizontal axis. In this configuration a tailstock can also be used, thus holding the workpiece "between centers."

With the table mounted on a secondary table, the workpiece is accurately centered on the rotary table"s axis, which in turn is centered on the cutting tool"s axis. All three axes are thus coaxial. From this point, the secondary table can be offset in either the X or Y direction to set the cutter the desired distance from the workpiece"s center. This allows concentric machining operations on the workpiece. Placing the workpiece eccentrically a set distance from the center permits more complex curves to be cut. As with other setups on a vertical mill, the milling operation can be either drilling a series of concentric, and possibly equidistant holes, or face or end milling either circular or semicircular shapes and contours.

* With the addition of a compound table on top of the rotary table, the user can move the center of rotation to anywhere on the part being cut. This enables an arc to be cut at any place on the part.

Additionally, if converted to stepper motor operation, with a CNC milling machine and a tailstock, a rotary table allows many parts to be made on a mill that otherwise would require a lathe.
