TOP-TURN CNC Lathe

Taiwan Largest Mill-Drill Turning Machine

• Handling turning, milling, engraving and drilling on curved
• Surfaces of large and long cylindrical workpieces, this machine is designed for the precision turning and milling of large-size printing rollers, straight-tooth shaft couplings, main shafts, main shaft bearing caps, main-shaft lubricating sleeves, yokes, scrolls, and cambered parts for shafts
• High PDI 0.001'

High Rigidity, High Precision Spindle

• Encased in well ribbed headstock for maximum heat dissipation. Thick cast iron casting to dampen vibrations
• Angular thrust bearings to absorb axial cutting foreces. Roler bearings with large bearing areas facilitate heavy cutting

Direct coupled ballscrews

• High precision preloaded ballscrews for reduced backlash
• Direct coupling eliminates motor backlash and improves torque transmission characteristics
• Absence of belt or gear drives remove transmission vibration

Slant Bed Design

• Torque tube cast into incline to prevent bed twisting
• 45° incline gives adds rigidity to bed structure
• Erogonomic design offers easy access to turret for tool changing Improves chip disposal

CS Main Spindle

C axis 0.001 high precision. It is the most stable electric control and the most complete design

Hydraulic Brake

Two-step brake system, offers the best working choice for users

Programmable Tailstock

• Mounted on slideways for maximum clamping stability
• Smooth tow along action by turret
• Hydraulic clamping to bed with variable hydraulic pressure to tailstock quill. All tailstock movements programmable by M-code

Separation System for Oil & Coolant

• A drip tray cast into bed is used to catch waste lubrication oil from Z axis slideway and ballscrew
• The drip tray is sloped so that the oil can flow to an outlet at the rear of the machine
• This system reduces contamination or dilution of the cutting fluid

Ball Screw Structure

• Using C3 degree ballscrew and making better precision in position accuracy
• Using strong lubrication system, confirming the precision of ballscrew and raising the life

Hardened Box Slideways

• Cast-iron slideways for maximum rigidity. Modular grey cast iron offers ideal friction properties without sacrificing toughness
• Heat treated using high frequency inductio heating to produce a wrap around structure with hard wearresistance surface & tough internal core
• A depth of 5mm for maximum wear resistance, ensuring accuracies are held throughout machine life
