Double-column machine construction provides high-speed and high-accuracy performance

1: |The double-column construction delivers high-accuracy machining over extended periods of operation
2: |High-accuracy positioning with direct-mounted ball screw and servo motor
3: |Spindle temperature control prevents changes in machining accuracy
4: |Linear roller guides for high rigidity are used on all axes

Ball screw core cooling

Temperature controlled cooling oil circulates through the ball screw cores. It ensures stable machining accuracy over extended periods of high-speed operation.

Ai Thermal Shield

Based on spindle speed and temperature of the machine, Ai Thermal Shield suppresses changes in the cutting edge position. It stabilizes continuous machining accuracy through meticulous machine control that takes into account temperature changes, machine position, coolant ON/OFF, and other factors.

High-accuracy built-in motor spindle for high-efficiency machining

Equipped with a built-in spindle, it eliminates the need for driving gear. It can reduce power loss and minimize vibration during high-speed operation to ensure exceptional surface finishes and maximum tool life.

Spindle specifications available to meet a wide variety of production requirements

The FJV (BT50) series is equipped as standard with a high-output, high-torque No.50 taper spindle. A 10000 min^-1 standard spindle that can handle the machining of various materials such as cast iron, steel, and nonferrous metal, a 7000 min^-1 high-torque spindle (optional) that is effective for rough machining of steel and cast iron, and a BT40 18000 min^-1 high-speed spindle (optional) that enables highly efficient machining of nonferrous metal such as aluminum and copper through high-speed machining are available. The optimum balance between exceptional spindle rigidity and a highly rigid machine structure ensures high productivity.

* Option

The compact spindle cartridge is designed for minimum interference.

This provides a wider machining area as well as the ability to use shorter tools for improved machining performance and accuracy.

Symmetrical spindle unit design

The symmetrical spindle unit design minimizes spindle displacement due to heat generated during machine operation.

More options to integrate process and achieve high productivity

Multi-face machining attachment (Option)

By utilizing the spindle indexing function and the hydraulic clamping unit mounted on the spindle-head face, continuous machining on all four sides can be performed with a single angle tool. It achieves process integration and improves productivity.

Angle holder for multi-face machining attachment (Option)

Five dedicated angle holders are available for a wide range of machining applications. Each angle holder can be exchanged automatically. The heavy-duty angle holder can be stored by adding a dedicated tool magazine.

1: Standard angle holder 2: High-speed angle holder 3: Angle tool holder (center through type) 4: Heavy-duty angle holder A-type (long) 5: Heavy-duty angle holder B-type (short)

Additional axis (Option)

Adding an additional axis that can be directly commanded and controlled by the machining program enables advanced multi-axis machining with the rotary table.

Automation solutions supporting labor saving and high productivity

2-pallet changer(Option)

The next workpiece can be loaded during the machining of the current workpiece for increased productivity.

Equipped with touch screen CNC system MAZATROL SmoothG

MAZATROL SmoothG is a CNC system with a graphical user interface and touch screen for easy operation. Various functions are provided to help reduce programming time and improve machining efficiency.

QUICK MAZATROL

Reduces program creation time
Programs can be created while checking the machining shape and process, which helps prevent mistakes and shorten creation time. By touching the 3D model, you are instantly moved to the corresponding processing unit, making it easy to modify the program.

3D ASSIST

Create programs directly from 3D CAD data
Workpiece and coordinates data can be imported from 3D CAD data to a MAZATROL program. No coordinate value inputs are required. It can reduce input errors and time for program checking.

QUICK EIA

Visualization of G code(EIA) programs
By visualizing the G code(EIA) program, it supports checking and editing of small program increments. Visible search on touch screen can reduce the time for program checking.
