Products > Ruckle > MRT Milling Tables-1250

The MRT milling table series up to size 1250 is designed for horizontal and vertical machining centers and used in milling, boring and drilling in positioning and continuous operation. The table design can be customized to the respective machine concept, for example, a variable mounting configuration, and allows different load capacities within one size. Ruckle also offers customized pallet changer systems and swiveling tables for a wide range of applications.

Ruckle milling tables: engineering solutions

At Ruckle, Customizing starts with a capital C. Because it is only when all the elements of a rotary table system have the best possible performance parameters that specific requirements can be optimally fulfilled. The MRT milling table series gives customers the option to select any pallet changer system in compliance with DIN 55201 or customer specifications. Customers are free to choose the servomotor manufacturer, and the milling table housings can be adapted specifically to the machine concept. On request, we provide hydraulic aggregates and cooling systems and interfaces customized for the machine.

Our standard milling tables come with roller contact bearings or, as an option, Ruckle also offers hydrostatic bearings in this series. Customers then choose between different drive system variants: worm gears, bevel gears, spur gears as well as torque motors.

For all sizes, the measuring systems are mounted directly onto the table axis. The milling tables can also be equipped with a Hirth serration as an option. This configuration allows for compensatation of extremely high machining forces. And, almost all of our milling tables can also be delivered as horizontal axis systems.

Products > Ruckle > MRT Milling Tables-1000

The MRT milling tables series 1000 is designed for millers and boring machines in gantry or traveling column design and is used in milling, boring and drilling in positioning and continuous operation. Because bearing arrangements vary, different load capacities are possible within the same size. Customized linear axes adapted to a specific application are also available.

Milling table by Rueckle: original and tailor-made

At Ruckle, Customizing starts with a capital C. The MRT milling table series size 1000 comes in a wide range of table tops. The tables are offered with worm drive, spur gear with twin pinion drive or electronically pre-loaded. All clamping systems are hydraulic. The measuring systems are mounted directly on the table axis on all frame sizes.

The MRT milling table also features high tilt resistance and excellent operating smoothness. Mounted hydrostatically or on an anti-friction bearing, the bearing arrangement guarantees excellent workpiece machining quality in positioning and continuous operation. The ambient temperature is also no probelm: the milling tables are also available with temperature control. Ruckle also equips the tables with an optional Hirth serration on request. The advantage: this option can compensate for extremely high machining forces. Almost all milling tables can also be manufactured with a horizontal axis.

Milling tables: we make it work

The MRT milling table series 1000 not only comes with different table tops, it also features bearing arrangements for component weights up to 200t and tilting moments up to 300 kNm. The drive of our milling tables is reliable and backlash-free to guarantee excellent control quality for optimum positioning and continuous operation. High accelerations are also guaranteed, even during changes of direction, as is perfect machining quality for heavy component weights.

The clamping system withstands machining moments up to 200 kNm; the positioning accuracy is less than +/-2 arcsec, and repeatability is less than +/-1 arcsec. The axial runout of the milling tables is 20m at a φ 2,500 mm and the radial runout is 5 μm at φ 100 mm. A central bore for oil distributors also delivers media to the fixtures. Due to the flexible design of the housing, the milling table can also be integrated directly in the machine.

Products > Ruckle > TRT Rotary Tables

The TRT rotary table series from Rückle was designed for use in vertical lathes and in millers. Depending on the intended application, the rotary tables can be designed with an integrated axis, as a stand-alone variant or as a sliding unit. Excellent control quality for positioning and milling operations is guaranteed by carefully selected torque motors in the TRT 400 to TRT 1000 rotary table series as well as by the the master-slave configuration in the TRT 1000 to TRT 4000 rotary table series. Customized linear axes are also available.

Rotary tables: Rueckle is adding a new twist:

It is only when all of the elements in a rotary table have the best possible performance parameters that the system can meet the customer's unique requirements. The rotary tables of our TRT series are all based on the same design principles, but are easily modified. An intermediate table top means that different table top sizes and chucks as well as variable bearing arrangements for different load capacities can be used. The drive train has a wide range of speeds and torques.

The bearing arrangement of the rotary tables with axial pre-load ensures high rigidity and uses anti-friction bearings or hydrostatic bearings, depending on the current application and the size. The oil distributer for the hydraulic chuck is seated in a large center boring. The measuring system can be mounted directly on the rotary table axis or indirectly using a gear mechanism. Another advantage: a labyrinth seal between table top and housing reliably prevents the ingress of chips or coolant emulsion.

Products > Ruckle > Griniding Tools

The GRT grinding table series is intended for use in vertical cylindrical grinding machines in single-column or gantry design. The table is fully integrated in the machine. The anti-friction performance of the direct drive guarantees uniform rotary motion. The hydrostatic bearing arrangement is designed as a separate bearing in both an axial and radial direction. The advantage: outstanding damping properties as well as a long service life for the grinding tables.

Grinding tables at the head of technology:

Customized down with attention to details: In the GRT grinding table series, an intermediate table top means that different table top sizes and chuck systems can be used. The measuring system on all machine sizes is mounted directly on the grinding table axis.

The drive consists of a torque motor available in two different performance classes. Both guarantee high speeds and acceleration as well as excellent control quality. An optional clamping system compensates for tangential moments that occur during special machining situations. Magnetic clamping chucks can be used to accommodate the use of slip rings which also allow the use of measuring systems with a large center bore. Another advantage: a labyrinth seal between table top and housing reliably prevents the ingress of chips or coolant emulsion. The grinding table housing can be adapted to the customer's machine design.

It's knowing how that matters:

Customer requirements decisively determine a product's characteristics - this is something the Ruckle Group gives top priority to. A wide range of table tops and magnetic clamping chucks are generally requested for the GRT grinding table series. Another important feature: a rigid mounting with excellent damping properties to bear component weights up to 15t. A back-lash free drive ensures optimum positioning and continuous operation and its running properties reach speeds of up to 200 rpm and sustain uniform rotary motion. The optional clamping system withstands machining moments up to 40 kNm and the positioning accurancy is less than +/-5 arcsec. The axial runout is 1 μm at Φ 1,600 mm and the radial runout is 1 μm at Φ 200 mm.

Products > Ruckle > Pallet Changing System

Our aim is to be able to offer customers a complete package from a single source. This is why we are constantly expanding our product range-for example, by including pallet changers and linear axes in our offerings. This was made possible by the acquisition of Maschinenfabrik Eimeldingen and the expertise of Fordertechnik Mayer.

Pallet changers from Rueckle: unlimited flexibility

Thanks to their modular design, the pallet changers from Ruckle come in a variety of configurations. Individual components, such as e.g. storage, straightening and feed stations can be equipped with different pallet clamping systems. The standard version is available for pallet sizes up to 2,500*2,500 mm and larger on request.

The pallet changers are rugged in design and also constructed for high load capacities. At the same time, users also profit from minimal pallet changing times.

Products > Ruckle > Steady Rest

If you're not moving forward, you're moving backward. This is whywe added a hydrostatic steady rest to our product range in 2012. The standard version is designed for shafts between 5 tons to 100 tons. The modular design also means the steady rest can be configured to meet customer requirements. The greatest advantage: the steady rest carrier can also be designed as an NC axis.

Steady rest: high accuracy despite heavy weights:

Whether for turning, milling or grinding operations, heavy shafts like those used in generators or turbines require additional support during machining. A nything else results in geometric errors. The solution: the Rueckle steady rest. It was a conscious decision to design the support as a hydrostatic steady rest. Compared to an anti-friction bearing-mounted steady rest, the hydrostatic steady rest prevents tracks on the shaft surface, eliminating costly reworking operations.

Sagging and bending of the shafts is prevented by a compensator. The steady rest case can also be designed with an infeed function in a manual and NC version.This greatly simplifies handling. The steady rest is also extremely flexible. The case and the supporting case are adjustable up to a radius of 300 mm. In addition to a complete steady rest, individual cases and supports are also available. The issue of safety was also given top priority. The case's infeed mechanism is self-locking, i.e. in the event of a power outage, the shaft does not change position.
