VC3016B Hi-speed CNC Gantry Milling Machine
1.The crossbeam moves, and table does not move. The machine still can be smooth and fast moving when carrying overweight workpieces; processing range, widely used in aerospace, automotive and other large precision tooling and parts processing industry;
2.The crossbeam used 2-axis ultra-precision synchronous driving, in providing a steady super power, while ensuring high-speed synchronous movement without deviation.
3.Crossbeam and 2-way bracket adopt advanced high-motion rigid design. Double linear guideways on the crossbeam use vertical distribution and provide a lasting and stable high dynamic accuracy and heavy duty cutting rigidity.
4.Z- with advanced hydraulic weight support, to ensure the micro-feed accuracy and precision perseverance.
5.High-quality resin sand cast iron, annealing and advanced aging and removal stress.
6.Using imported high precision heavy duty linear guideway and ball screws, high-speed and stable movement strong and easy cutting.
7.Imported high-speed precision spindle, strong cutting rigidity, can be used in pneumatic knife and rigid tapping, together with growth spindle speed can be 24000rpm, finished processing from milling to engraving.
8.Choosing special tool, processing big size complex workpiece, together with 90 degree or universal angle milling head can finish 5 faces processing.
9.Elaborate design the lubrication system, and supply oil for movement parts for ensuring machine stable and long time working.
10.Choose tool auto-checking instrument to ensure testing tools damage regularly and guarantee processing precision.
11.The machine precision adopts Britain Renishaw company laser interferometer and ballbar for testing and make perfect machine working.
12.Advanced Spain FAGOR system, high speed and high precision, complete function and stability.
13.We are make sure the machine precision perfect without flaw through the machine parts processing and assembly.
Comparison for Gantry Milling machine with moveable table and immovable table
With moveable table | With immovable table | |
Carrying workpieces | The machine with 3M*2.2M size ,the bearing capacity is about 10 tons, and should not be overload. | The workpieces have no influence on the machine, the bearing capacity is about 20 tons as long as the workpice can be placed. |
Moving speed and processing speed | The speed should not be too fast when carrying big size worpiece, the bigger size of the workpiece, the slower speed. | The speed has no reference to carrying workpiece, the moving speed can get the machine designing speed, especially with high efficiency when processing big and heavy workpiece. |
Precision retaining | Uncertain damage of guide and lead screw for uncertain heavy of the worpiece. The stability is not very good. | The moving parts are considered when designing, with high precision and good stability. |
Guideline damage | Speed up worktable guide damage if long time processing heavy workpiece. | The moving parts with good stability and littledamage. |
Servo movement | Different workpiece with different weight, so it can not be taken account when adjustment. Only can choose one weight reference to adjust servo motor and system. The servo motor and system can not retain stability for workpiece difference. | Payload weight is very important to servo motor and system, so stable and close payload is a important factor in servo motor and system stable using. |
