Machine tool processing scope Drilling range: Φ 25 ~ Φ130mm

Boring range: Φ40 ~ Φ250mm

Workpiece outer diameter range: Φ60 ~ Φ400mm

Machine tool functions

Drilling, boring functions.

Drilling: BTA drilling method, chips are removed backward through the tool bar.

Boring: Push boring method, which discharges chips forward through the bottom hole of the workpiece.

Main components of machine tools

Bed body, bedside box, oil feeder, tool bar bracket, drill pipe box, sliding guide rail, gear

rack and pinion, cooling system, control system, electric box, workpiece bracket, etc.

Workpiece clamping

The manual three-jaw chuck on the bedside box clamps one end of the workpiece, and

the oil feeder cone plate automatically tightens the other end of the workpiece.

Machine tool control system

Control system: PLC/FANUC

Z-axis: the longitudinal feed motion of the drilling box, and the servo motor drives the

rack and pinion mechanism through the reduction mechanism.

X axis: The oil pressure head servo tightens the workpiece, and the servo motor drives

the rack and pinion mechanism through the reduction mechanism

The basic parts such as box, bed, and pallet are precision cast of high-quality cast iron.

After the casting is completed, they undergo two aging treatments to eliminate internal stress, stabilize the structure and size, and improve mechanical properties.

Machine Bed

The bed body is cast with resin sand, and after casting, it is normalized. The bed adopts

a split structure, which is assembled together by high-strength bolts and positioned by

taper pins.

Adopt double rectangular sliding guide rail, precision grinding, guide rail surface

quenching hardness is high.

The bed is equipped with a helical rack for cutter feed transmission, and the rack is

precisely machined and quenched. The machine tool has large load capacity, sufficient

rigidity and stable transmission.

V-shaped inclined bars are arranged inside the bed body, which has high support

strength and is not easy to deform; The outer wall of the bed directly supports the guide rail,

which can bear large cutting force. The rigidity of the guide rail is good, and it is not easy to

deform and shake during processing, which is conducive to improving the machining quality

and efficiency of the machine tool.

An oil return groove is cast around the bed body, an oil retaining cover is installed on

the oil return groove, and the cutting oil on the bed body is automatically returned to the

cooling oil tank.

Headstock

Is used to drive the workpiece to rotate and is fixed at the left end of the bed body.

Manual 3rd gear, stepless speed regulation in gear, servo spindle motor drives the

spindle to rotate through belt and gearbox, and a manual chuck is assembled at the front

end of the bedside box for clamping workpieces.

Gears are precision grinded; The tooth surface of the gear is quenched by high

frequency, so that the gear can obtain high strength, high hardness, high wear resistance

and high fatigue limit, and can bear relatively large alternating load and impact load.

The external lubricating oil tank is used for cyclic lubrication of gears and bearings, and

a low liquid level alarm device is installed in the oil tank.

A button plate is installed on the bedside box, which has the functions of spindle

inching, feeding forward, feeding backward and emergency stop.

Oil Pressure head

Used for tool guidance, tool oil supply, tool bar support.

The servo motor is used to drive its axial movement, which can adapt to the processing

of workpieces of different lengths, and tighten and loosen the workpieces. The servo motor

can be operated in torque mode or position mode.

The oil pressure head slewing bearing is installed inside the oil Pressure head body,

which has good rigidity and high slewing accuracy

The rotary seal is installed on the outside of the right end of the oil dispenser body,

which is convenient for maintenance.

Install the tool bar support sleeve at the right end of the oil feeder, which is used to

support the tool bar.

The left end of the oil pressure head is equipped with a guide sleeve, a conical disc and

an oil retaining device, the conical disc is used for positioning the workpiece, and the guide

sleeve is used for guiding the tool.

The oil retaining device is a push-pull structure, and an oil receiving box is installed at

the lower part of the oil retaining device, so that the cutting oil flows back to the oil tank

Drilling box

Used to drive the cutter rotating, mounted on the feed pallet.

Manual 3rd gear, stepless speed regulation in gear, servo spindle motor drives the

spindle to rotate through belt, pulley and gear train.

The left end of the spindle is equipped with a toolholder connecting sleeve for holding

the tool.

A chip discharge bucket is installed at the right end of the spindle for discharging chips.

Gears are precision grinded; The tooth surface of the gear is quenched by high

frequency, so that the gear can obtain high strength, high hardness, high wear resistance

and high fatigue limit, and can bear relatively large alternating load and impact load.

The external lubricating oil tank is used for cyclic lubrication of gears and bearings, and

a low liquid level alarm device is installed in the oil tank.

Tool Bar Support

For supporting the tooling bar;

It adopts a high-rigidity integral structure, and is equipped with a support sleeve, which

can absorb the impact, jitter, etc. generated during processing.

The automatic hanging and pulling mechanism is installed. When the tool is withdrawn,the feed pallet can automatically pull the tool bar bracket back to the initial position

Cooling system:

It is mainly composed of cooling pump, chip receiving box, oil tank, etc. to provide

enough cutting oil for deep hole machining.

On-ground fuel tank, the fuel tank is fully welded with high-quality steel plate.

Install a telescopic protective cover between the chip boxes on the fuel tank to cover

the fuel tank and prevent sundries from falling into the fuel tank.

The pressure, liquid level, oil temperature and flow rate of cutting oil can be digitally

displayed on the control station.

Feed pallets

Used to drive the tool to move axially.

The automatic lubrication station is used to lubricate the sliding guide rail surface

regularly and quantitatively.

A button plate is installed on the pallet, which has the functions of inching, feeding

forward, feeding backward and emergency stop of the spindle of the drill pipe box

Lubrication System

The sliding guide rail surface of the feed pallet is lubricated regularly and quantitatively

by the automatic lubrication station, and has the function of low liquid level alarm.

The bearings and gears of the bedside box are lubricated by independent external oil

tank circulation and have low liquid level alarm function.

The bearings and gears of the drill pipe box are lubricated by independent external oil

tank circulation and have low liquid level alarm function.

The oil pressure head support plate and the tool bar support support plate are

lubricated by manual lubrication pump.

Workpiece carrier

Used for workpiece prepositioning.

The operator first places the workpiece on the workpiece bracket, and after the

workpiece is clamped and positioned, the workpiece leaves the bracket.

The V-shaped frame on the workpiece carrier is manually raised and lowered by using

the T-shaped screw.

Center frame

For supporting workpieces; Three-point closed central frame structure with two rollers

below and one roller above; The two rollers below adjust the lateral position by the lead

screw
