RST B 20 HEX - RST B 60 HEX Ball coupling
Hydraulic elevating rotary indexing table with Electrical cushioning, eXternal control and Ball coupling
The appliance is usually assigned where hydraulic is already being used with tool, rotary pulsatory or special machines.
However heavy loads, extremely powerful machining and a considerable amount of switching require the assignment of the hydraulic rotary indexing tables.
This appliance type distinguishes itself with its low energy consumption and high frequency of switching.
This appliance type distinguishes itself from the „PEX“ design with its economical consumption of power when frequently switching.
Likewise here the piston limit of travel is assessed by the built-in electrical control. These limit switches are connected with the magnet valves or the hydraulic unit via an electrical control.
The respective program controls offer manifold possibilities such as oscillating motion, differing fractional pitches and other functions.
The switching time of the division is dependant on the amount of material conveyed by the hydraulic. This can be calculated with the already existing calculation.
These valve combinations or the entire hydraulic unit can be supplied with an electrical control base. The mechanical construction of these appliances is very resistant to machining power from any direction. Whereby the fixed ServoPress ball coupling is a guarantee for superlative and consistent precision. This interlocking kind is free from wear and tear, is insensitive to dirt and offers a rigid coupling even under rough assignment conditions. The number of balls is the basic division (GT) in the appliance from which the subsequent number of appliance divisions is taken. Division adjustment with the F-design is done by changing division pins. An adjustable „V“ division design can be supplied on request. Using this the 10 most important divisions can be easily done with a hand wheel. Automatic lubrication dosage is built into the appliance facilitating a maintenance free operation. Standard appliances are protected against splashed water. The appliances can be fitted with an additional sealing when being used under flood of coolants. An abundant selection of accessories and special designs round of this programme that hardly leaves any wishes unfulfilled. Here is a brief selection:
T-slots in the table plate, 90° degree angle plate, stationary limit switches instead of the electrical limit switches, pneumatic weight compensation, double drive cylinders, differing fractional pitches on to integrated NC control.
The larger RST HEX types of design with their enormous interlocking power against distortion or tilting are to be used with big loads.
