HTC Large Flat Bed CNC Lathe
Applications:
CNC lathe of this series is designed for machining various shafts and plates parts. It is also used for turning threading, arc, cone and inside and outside curved surface of rotary parts, meeting the speed requirements of cutting ferrous metal and non-ferrous metals.
This kind of machine tool is primarily used to efficiently and accurately machine large-batch rotary parts in many industries, such as shipping, locomotive, aerospace, military, metallurgy etc.

Introduction of HTC Large Flat Bed CNC Lathe:
This CNC lathe comes in several models, including light, middle, heavy and super heavy models. The max. swing diameter is 1000mm-3150mm and the max. load between two centers is 5ton-160ton.
Different guideway is adopted by different model. "V" type guideway is adopted by the light model, double rectangular guideway is adopted by the middle model, integral quadri guideway is utilized by the heavy model, and separated quadri guideway is used by the super heavy model.
Thanks to the reasonable stiffness arrangements of bed, spindle and tailstock, the stiffness of the whole machine tool is greatly enhanced, assuring the stability at heavy cutting status.

Structure Features of HTC Large Flat Bed CNC Lathe:
Headstock
The headstock adopts imported high precision bearing and quenching grinding gear. Hydraulic steps changing is available.
Chuck
The chuck uses domestic famous brand product for large clamping force and high reliability. 3-jaw and 4-jaw chucks are optional for your choice.
Turret
Reliable horizontal, vertical and frame turrets with high positioning accuracy and good stiffness are optional to meet your specific needs.
Operation Panel
Adopt FANUC or SIEMENS CNC system, which can achieve the servo control with high speed and precision.
Servo Motor
FANUC or SIEMENS AC servo motor, providing fast response speed and high reliability
Tailstock
Mechanical tailstock, hydraulic tailstock and electrical tailstock are available for your choice. The tailstock can be divided into upper and lower structure and whole boxing one. The high-precision spindle bearing is imported from other countries.
Bed
The bed is casting part with reasonable ribbed layout. It is of high stiffness due to the assistant guideway.
Carriage & Slide
The carriage and slide are casting parts with reasonable inner ribbed layout.
Thanks to the adoption of the imported ballscrew or pinion and precise rack, high precision and accurate transmission are guaranteed.
