- Rigidity secured through box guideways
- Increased contact area between the saddle and cross-slide
- Increased swing for machining large workpieces
- Applying an AC Servo Motor to enhance machining reliability
High Precision & Rigidity, One-Piece Structure
The L4000L Series features a 45° slant bed design which is developed through finite element analysis (FEA) to absorb vibration and minimize thermal displacement so as to maintain high stability.
Guideway
Box Guideway
With the mounting of box guideways on all axes, the machine offers excellent vibration absorption even against during heavy-duty cutting, enabling high-quality machining.
Improved saddle rigidity
The contact area between the saddle and the cross-slide has been increased for high rigidity.
Ball Screw
Large diameter ball screws with preloading prevent deformation due to heat. Also double-anchor suppport method improves rigidity.
Main Spindle
Spindle Ideal for Heavy Cutting
High-precision double-row cylindrical roller bearings and angular contact bearings offer increasement in rigidity of the spindle. In addition, the two- step gearbox guarantees strong torque at low speed and stable machining capability at high speed.
Spindle Gear Box
Gear shift of spindle provide stability and high torque during low speed.
C-Axis Control (‘M’ Type)
The C-axis is capable of 0.001° control when milling turret is applied. Machining capability is strengthened with turning and milling operations.
Turret
Standard Turret
The turret of L4000L series is applied with high performance AC servo motor, improving machining reliability. 3-piece coupling shows excellent performance in indexing. Powerful hydraulic tool clamping minimizes tool tip deviation caused by load.
70 bar High Pressure Coolant [option]
Turret is designed to utilize 70 bar high pressure coolant and it shows optimum performance in machining difficult-to-cut material.
BMT75 Mill Turret (‘M’ Type)
The BMT turret secures the tool with four bolts and key on the tool mounting surface of the turret, making it possible to powerfully fix the tool, ensuring high reliability in rigidity and precision.
Mill Tool Holder
Machining capability has increased with the addition of straight milling head tool holder.
Various Devices for User Friendly / Options
High-performance Tail Stock
The large tailstock of Ø120mm is applied for high rigidity. The tailstock provides extra support with 120mm (4.7′′)travel. (MT#5 Built-in Tail Stock : Option)
Steady Rest [option]
For long parts, such as shafts, the steady rest increases rigidity and minimizes vibration.
Automatic Q-Setter
Cutting tools are calibrated quickly and accurately with the addition of a q-setter. Each tool tip is touched off manually using a sensor that inputs the position automatically.
Linear Scale
Linear scales increase positioning accuracy and reduce distortion caused by thermal growth, thus ensuring a more accurate finished part.
Long Boring Tool holder
When using long boring tool holder, deeper inner diameter machining is possible, enabling faster and more precise machining.
