Structure
High-Rigidity Design For Column & Bed
The stable design of column assembly surface on bed top enables securing the fundamental rigidity of the structure.
Guideway
The KF5700-B II Series are equipped with box guideways to enable
distributing its feeding force evenly to each slideway. It boasts excellent rigidity, a stable feed structure, and an increased box guide slideway, thus providing an excellent heavy-duty cutting performance.
Double Anchored Ball Screw
The pretensioned ball screw minimizes the expansion and contraction according to the heat and further reinforces the rigidity by the double anchor support method. In addition, the coupling of the ballscrews and the highly reliable digital servo motors are connected by metal plate
couplings, to reduce coupling breakage and backlash
Spindle
Arbore cuplaj direct
The directly coupled spindle at a maximum revolution of 12,000rpm, allows highspeed processing. Additionally, the large diameter and the thickness of the spindle add to the stability of the machine
BBT40 coupling
The Big Plus shaft system (BBT40) ensures double contact between the shaft and the tool holder.
Spindle Cooling
The spindle cooling system minimizes thermal displacement which can happen during lengthy machining operations, and offers continued accuracy based on the thermal stability.
Through Spindle Coolant (20/30/70 bar)
Through Spindle Coolant is exceedingly useful when drilling deep holes. It helps increase the lifetime of the tool, while decreasing cycle time. The improved quality of rotary joint prevents oil leakage.
Tool Magazine
High Speed ATC
Position control through twin arm ATC on servo motors has been
improved drastically. In addition, tool exchanging has become
easier, reducing specific cutting time tremendously.
Position control on the Twin Arm ATC has improved drastically.
The twin arm ATC enables faster tool change and increased
productivity
Magazine
A magazine that can attach various tools between 24~40 EA was adopted to increase the range of selection for machining tools, and the overall size of the magazine was reduced to reduce vibration during magazine rotation to improve surface finishing
Interior Screw Chip Conveyor
Dual screw type chip conveyors are located at each side of the bed which makes it convenient to remove chips. The interior screw and the chip conveyor operate at the same time and can be controlled separately at the time of prior consultation.
(Three screws for rear-type conveyor: 2 sides + 1 front)
Furthermore, chip disposal capability significantly has been improved due to optional bed-flushing coolant.
