Structure and Feature:


Column

CNC Single Column Vertical Lathes717.png1. The column adopts the optimization design of box-type structure and reasonable layout stiffener, so as to realize the good thermal stability, high strength and high rigidity.

2. The column guideway adopts grinding after quenching, to improve wear resistance and prolong service life. The guideways adopt stainless steel sealing cover for protection and reduce the corrosion rate.







Worktable

CNC Single Column Vertical Lathes1345.png1. The worktable base adopts high strength and high rigid cast iron material, to improve stability and absorb vibration. Unique thermal symmetric structure, overcome the spindle temperature rise effect on machining accuracy.
2. The spindle is equipped with spindle encoder, to realize constant linear speed cutting.
3. Worktable and worktable base and motor separation, relying on the V-type belt drive, max. limit reduces the vibration of the motor heat directly affect the machining accuracy.




Beam

1. The beam guideway has very high wear resistance after quenching and grinding, so as to guarantee long-term stability and high processing accuracy.
 2. Horizontal guideway width large with wide guide structure, ball screw in the middle of the guide rail thoroughly solve the problem of drive torque, the guideway adopts the plaster guide rail, good seismic performance, large loading capacity, decrease friction coefficient.
3. Beam lifting adopts two clamping points, to ensure the accuracy of the lifting beam.


Spindle Unit

Worktable uses integrated, high-rigidity, high precision and short fixed-type spindle structure, the spindle is equipped with a set high precision thrust ball bearing and a set double row short cylindrical roller bearing. Compact structure, at the same time bear radial load, the axial load and tilting moment, and under the overloading elastic deformation is small, improved the precision of the rotation of the worktable and carrying capacity for CNC single column vertical lathes.

Main Drive

1. Main transmission adopts gear drive, gears adopt high strength material and quenching and grinding process, so it can realize high speed cutting force, high transmission accuracy and rate, and reduce the vibration and noise of the transmission.
CNC Single Column Vertical Lathes3211.png2. Main transmission is controlled by horizontal spindle servo motor, can realize four shifts stepless speed, it is suitable for processing all material workpiece, to realize spindle wide speed changing and large torque heavy cutting, meet low-speed and heavy cutting for big diameter workpiece, and high-speed cutting for smaller diameter workpiece.
3. Large gear adopt high grade alloy steel, through quenching treatment and being ground by high precision gear grinding machine, to reduce noise of spindle running.


Four Station Electrical Tool-Post

CNC Single Column Vertical Lathes3730.png1. High Positioning accuracy, large clamping force, large loading capacity, stable and reliable.

2. The unique dovetail cutter holder, more accurate positioning, greater clamping force.







Electrical Cabinet

1. Electrical cabinet placed directly within the column, so the structure is more compact, save space. Beautiful appearance, wire marking clear and complete, wiring and tidy; The connection of the electrical cabinet to bed adopt the special cable connection.
2. Electrical cabinet is equipped with air condition, safety and standard, to ensure controller constant temperature, the stability of the controller.


Precise Oil Cooler

Precise oil cooler can prevent the machine tool thermal deformation, stable oil pressure, prevent oil shock, improve the processing precision, reduce the error of the mechanical action, reduce maintenance costs of machine tool through cooling hydraulic oil of machine tool.


Automatic Lubrication

Guideway and screw adopt centralized lubrication, use a set automatic lubrication station, through the control of the electric system can all lubricating points for quantitative regularly, lubrication operation is more simple, CNC single column vertical lathes have a long service time.
