Fast and reliable automatic tool change (ATC)
Hydraulic tool change, stable tool change, big grasping force, the maximum tool weight of 18kg.
The knife house can hold 24 knives
Adopt push type tool storehouse, clamp type hydraulic manipulator, the tool storehouse capacity is large, the occupation area is small
High rigidity structure excellent manufacturing
- The optimum structure of the machine tool was designed by using the CAD software Solid Works and the finite analysis/dynamic analysis system.
- All large parts are made of closed box structure, thick wall and multi-bar, high quality gray cast iron resin sand mold, through multiple stress relief procedures, extremely rigid (casting suppliers are export OEM factories).
- The machine tool adopts horizontal bed moving column, T – shaped layout, thermal symmetry, thermal compensation design.
- 3-point positioning and balancing installation
- The three-way guide rail of the machine adopts the precision linear roller guide rail made by the German technology of Taiwan SIYIN Co., Ltd., which can move fast and realize high speed, high precision and heavy cutting.
- High micro feed precision, good accuracy retention (can maintain the accuracy of 8-10 years.
- Machine high stiffness guide rail is installed on the datum surface, and is grinded by imported guide rail grinder with high precision.
- Spindle taper hole quenching, worktable quenching has a proprietary technology, to ensure the stability of hardness and precision.
- The three axis adopts high precision ball screw and AC servo motor to drive directly, prestretching, eliminating clearance and good precision.
- This machine tool design technology – refering to the foreign advanced vertical/horizontal machining center manufacturing technology, to achieve stable machining accuracy reliability, thus further improving the production efficiency.
