Floor Type Boring Machine

The floortype boring machine is developed by RIFA independently. The key parts ofthe machine are designed corporately by special institution. It featuresperfect configuration, excellent performance, high accuracy and rigidity, etc.

Features
1. Thefunctional units of the floor type boring machine are ofserration and modularization, and various optional functions are offered tosatisfy the customers’ unique requirement.
2. The floor type boring machine is designedwith X Y, Z and W axes. It could beexpanded with B and U axis and it is controlled with SIEMENS full digital 840Dcontrol system which makes any four axis linkagepossible and enables automatic tool changing and automatic milling headchanging.
3. The machine is ideally used for the multi operationcutting, such as milling, boring, drilling, and tappingof the big tank type multi surfacework pieces.
4. The floor type boring machine is used in theindustries of petrochemicals, refrigeration, metallurgical, steam turbines,military, etc. It is especially used forthe machining of the work pieces withcomplicated surfaces or with complex operations.

Structural Features of the Floor TypeBoring Machine
1. The gap eliminatedgear box engaged with Germany racks is used for X axis, ensuring highertransmission accuracy, stronger load capacity and accuracy stability.
2. The Y axisis equipped with double motor and double screw.
3. Variousaccessory heads are optional for customers, providing high efficiencyhead changing and leading to the expansion of the machining capacity of the floor type boring machine.
4. The X, Y and W axes are provided with sentinel hydraulicclamping functions, ensuring high rigidity and high machining accuracy.
5. Constant flow hydrostatic guide waysare used for the X, Y and W axes,providing increased rigidity, loadcapacity and lower attrition.
6. A rotary table with V axisand B axis is optional, providing six axiscontrol and any four axis linkage for complexcurved surface machining.
7. Varietiesof the compensation balance systems maintain the accuracy of the square ram dueto the spindle head force system changing.
