Rigidity and high stability in machine structure
Design of the main structural castings uses FEA to conduct analysis Quality castings are used with resin sand molding special box-type structure and advantageous reinforcement thus the machine offers high rigidity and perfect vibration-absorbing abilities

Three-axis feeding system
VDL series machining centers adopt linear guideway for three-axis feed
Its features include fast response good rigidity high precision and low noise as well as less friction Accuracy of rapid traverse and interpolation compensation are greatly improved Z-axis feeding of VDL-1000 VDL-1200 VDL-1400A vertical machining centers adopts sliding guideway thus greatly improves loading capacity of spindle heavy cutting provides resistance damp and high anti-vibration features
VDF series machining centers three-axis feed adopts sliding guideway which is hardened with high-frequency treatment together with low friction TURCITE-B plastic board that offers low noise and better resistance thus improves the static and dynamic rigidity of the feeding system
Machining accuracy is getting much better through a good balancing system with a supplementary central guiding device in Z-axis or through cylinder balancing device to guarantee stable fast dual-direction traverse and improve machining accuracy
Y-axis guideway is designed with reasonable structure to support heavy load and thus to guarantee better machining accuracy
03 grade high precision ball screws are used in all three axes which provide precise preload better transmission rigidity and reduce heat deformation
High precision laser interferometer is used to compensate ball screw pitch error and clearance

Spindle is designed with high rigidity and good accuracy using precise angular ball bearings P4 Floating type tool pulling system is adopted to avoid load on spindle bearings when the tool is released and offers longer bearing life Synchronical tooth belt with large torque is introduced in spindle transmission to avoid slipping and guarantee free friction and low noise

Fast and reliable tool changing mechanism
Different drum or swing arm type or rotary type ATC of 16/20/24 tools are available The required tool can be selected in either direction whichever the nearest and the turret rotates fast stably and reliably Tool changing system is fully tested and can satisfy long period continuous working

ATC with swing arm Drum type ATC

Temperature control device is adopted to dynamically monitor the spindle temperature and avoid spindle deformation due to temperature increase thus guaranteeing the working accuracy and longer life of the spindle

The working table is designed with coolant grooves The machine is supplied with a spray gun for table and a large coolant tank

Electric control system
Different brands of high-performance CNC controls and AC digital driving device are available to meet customer requests The electric is designed in compliance with CE standard and supplied heat exchanger to guarantee the control unit working stably The machine is supplied with portable manual pulse generator with spring cable and rotary table as well as 9 CRT Chinese and English display unit
