- High-speed roller type LM guide in all axes
- Hyundai WIA mold package for optimal processing of mold parts
- Improved user convenience by applying the latest controller of FANUC
Wall Type Structure
The strucutre of KF7300/5A is a wall type for high-precision machining.
In particular, the feed is separated from the table to maintain high-precision machining even in heavy work.
Optimization of Installation Area
Installation is convenient even in small spaces with compact size of 10.1m2 and it improves space efficiency for the factory of customers.
Work table
5-axis Tilting Rotary Table Standard Application
The rotary table allows users to produce a wide range of complicated work pieces. It is possible to clamp each axis for extra rigidity and accuracy when machining.
Spindle
Direct Driven Spindle
The directly coupled spindle at a maximum revolution of 12,000 rpm [Opt.20,000 rpm], allows high-speed processing. Additionally, the large diameter and the thickness of the spindle add to the stability of the machine.
Built-in Spindle
The built-in spindle minimizes spindle vibration, enabling outstanding performance in a high-precision cutting environment such as complex shaped work-piece.
Ram Type Spindle
The main shaft of KF7300/5A is a ram-type application, which minimizes the weight of the transported body and greatly improves the dynamic performance.
Through Spindle Coolant [Option]
Through Spindle Coolant is exceedingly useful when drilling deep holes. It helps increase the lifetime of the tool, while decreasing cycle time.
High-Speed Roller LM Guideway
For processing the highest quality mold products, the KF7300/5A is designed with roller LM guideways for high rigidity and enhanced acc/ deceleration.
Grease Lubrication Method
Significant cost savings is achieved by incorporating the grease lubrication system versus the oil lubrication method.
ATC & 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
The tool magazine holds 30 tools as standard and 60 tools as an option. Due to the wider selection of tools and the random tool selection method, tool change time has improved.
(KF4600 II : Opt. 40 tools)
Direct Chip Discharge Structure
The structure was designed for the chip to fall directly to the lower part of the bed to improve chip discharge capability, and the high-temperature chips and coolant are discharged immediately without accumulating on the bed, minimizing thermal deformation of the structure.
