Workpiece OD range: Φ 15~Φ70mm

 Machine type:

Single spindle

Double spindle

Four spindle

Working mode :

Both workpiece and cutting tool

rotate in opposite directions, cutting tool feed.

 

 

CNC system :

GSK

FANUC

SIEMENS

 

 

Machine bed:

Material : Casting iron HT300

Casting technology : Resin sand wood mold casting

Undergo twice aging treatment to eliminate the internal express, make the machine bed more stable,won't

deform

The triangular reinforcing ribs inside,make the bed with high precision, long life, strong rigidity and good precision retention

The inclined oil return slot cast around the bed,

so that cutting oil can return to oil tank soonest for cycle use

All the machine bed will be inspected strictly .

Machine bed inspection report:

 

Microstructure inspection

Drill box :

Cast by super casting iron HT300

Drive the cutting tool to rotate ;

The spindle is driven in front, which is beneficial to protect the main motor and easy to exchange the gun drill .

Adopts HIWIN brand rolling linear guide rail, which ensures the stability and precision of the machine .

The spindle bearings of the drill box adopts NSK brand high-precision angular contact ball bearings:

 

Spindle bearing:

High rotation accuracy,ensure the stability during high-speed running;

High bearing capacity,can withstand both radial and axial loads at same time;

Good high-speed performance,low frication to reduce heating,suitable for high-speed spindle;

Rigidity is adjustable ,can reduce virbration, improve system rigidity;

Long service life and reliable ; Low temperature+Low noise ;

The rear end of the spindle is equipped with American Deublin rotary joint to provide stable cooling supply for deep hole machining and ensure stable cutting of the machine .

Headstock:

Cast by super casting HT300

Drive the workpiece to rotate, speed fixed;

Adopt high-precision angular contact ball bearings;

The spindle is driven in front,which is convenient to load/unload the workpiece and protect the main motor ;

Headstock is installed on the linear guide rail,easy to adjust its longitudinal position

The extension and contraction of spindle is controlled by hydraulic system, which can reduce the

auxiliary length of cutting tool . If machine has multi spindles, it can ensure the inlets of all holes are same , good to realize the automatic optation .

the space between drill bar support rest keep same when drill box at any position

Coolant system :

Including oil tank, Auto chips converyor, Paper filter , Oil chiller, High pressure pump groups, etc. ;

Adopt vertical structure , save space ;

The pressure,level,temperature and flow of cutting oil is displayed on the CNC operation station.

Lubrication System :

The linear guide rail sliders, screw nut, and spindle are uniformly

lubricated by the auto lubricating pump station timely and quantitatively ;

Has low-level alarm function .

 

Electric cabinet :

Adopt America Rittal structure, won't deform;

Main low-volatage electric componets use SCHNEIDER brand ;

With air-conditioner , ensure the electric componets inside can work under a reasonable temperature, prolong the service life;

With sealing strips to prevent the dust from going inside the electric cabinet ;

Electric cabinet is integral with the machine main body,save space.
