VMC1100 4 axis cnc machining center FANUC

VMC1100 CNC machining center

Vertical CNC machining center is mainly used for machining spare parts with high precision,multi-procedure,complicated shape,such as plate,disc,shell,mould etc.It can complete milling,drilling,reaming,boring,tapping continuously as well as precise machining of slant face,two-dimensional and three-dimensional surface in one single clamping, the process is programmed and batch,  production cycle is shortened, thus , the users will obtain good economic benefits.

Functions and characteristics

1.General layout of machine

VMC1100 vertical machining center adopts vertical frame layout, the column is fixed on the bed,spindle box moves up and down along the column(Z axis), the saddle moves longitudinally along the bed(Y axis), the table moves crossly along the saddle(X axis).The large parts all adopt high strength cast iron material,including bed,table,saddle,

column,spindle box etc.. They are optimized by 3D computer software, reasonable arrangement of stiffened plates and complete heat treatment process to eliminate residual stress, ensuring the machine with sufficient strength, rigidity and high stability.

2.Cnc System

The machine is equipped with FANUC system or Siemens 808D advance sytem, it's with complete function and simple operation; stable and durable CNC system platform provides great flexibility for the assembly arrangement of machine by distributed operation component,driving component and I/O component;net interface and USB are standard, and it's also with DNC on-line processing function.

3.Drive system

X/Y/Z guide ways adopt Taiwan PMI 45mm roller linear guide ways,which has small friction  and wear, high positioning accuracy and sensitivity,small vibration on high speed,long service life, interchangeability, as well as excellent servo drive performance, improving machine accuracy and stability.The Z axis headstock is a six-load sliding block structure to ensure the rigidity of the whole machine.

X,Y,Z axis servo motors connect with Taiwan PMI directly by elastic coupling, realizing gap-free drive, flexible feed, accurate positioning and high transmission accuracy.

Z axis servo motor is with self braking function,in the case of power failure, it can brake automatically and hold the motor shaft tightly, offering safety protection.

4.Spindle

Spindle adopts Taiwan 10000rpm spindle unit with high precision and rigidity,highest speed can get 8000rpm. P4 grade NSK bearing is used for spindle specially. The spindle is assembled under constant temperature and then pass through dynamic balance calibration and running test, improving the whole spindle's service life and reliability.The spindle can realize infinite speed variation in its speed range, and it's controlled by motor built-in encoder and can realize spindle orientation and rigid tapping function.

5.Tool magazine

Taiwan 24pcs arm type tool magazine is installed on the side of column,when tool changing, the magazine will be driven and positioned by roller cam mechanism, when the spindle arrives at the tool changing position,ATC will return and grasp the tool, ATC is hobbing cam mechanism,after prepressing, it can run at high speed and no noise, so that the tool changing process is quick and accurate.

6.Cooling system

Large flow cooling pump and large volume water tank are equipped to ensure circulation cooling,power of cooling pump:840W,66.7 L/min large flow cooling pump supplies the cooling fully.Spindle end is equipped with cooling nozzle, it can be either water cooling or air cooling, and can be switched at will.Air gun is equipped for cleaning the machine.

7.Pneumatic system

Pneumatic triplex can filter the impurity and moisture in the air source and prevent the damage and corrosion of machine parts caused by impure gas.Electromagnetic valve is controller by PLC program which can make sure the actions can be finished quickly and correctly, such as spindle umclamping the tool,spindle blowing,spindle clamping the tool,spindle air cooling etc.

8.Machine guard

The machine guards conform to safety standard,not only prevents coolant splash, but also ensures safe operation,and the appearance is beautiful. Every guide way is equipped with protection cover which can prevent chips,coolant from damaging guide ways and ball screws.

9.Lubrication system

Guide ways and ball screws are all centralized auto lubrication,each node is equipped with a quantitative oil separator which will inject the oil to lubricating parts quantitatively and regularly, ensuring uniform lubrication and effectively reducing friction resistance, improving movement accuracy,ensuring the service life of ball screws and guide ways.

10.Chip removal system

The iron chips produced in the processing fall directly into the protective compartment. The internal slant structure of the protection allows the iron chips to slide smoothly into the drawer of water tank.
