Industrial Drilling And Boring Machine

1. Industrial drilling and boring machine appearance :

2.  Industrial drilling and boring machine brief :

2.1 Machine processing capacity :

Drilling diameter range : Φ25~Φ100mm

Boring diameter range: Φ40~Φ200mm

Workpiece OD range : Φ60~Φ400mm

 

2.2 Industrial drilling and boring machine functions :

Drilling hole : BTA drilling method,remove the cutting chips backward through the drill bar .

Boring hole : Push boring method , remove the cutting chips forward through the basic hole of workpiece .

 

2.3 Industrial drilling and boring machine main structure:

2.3.1 Main parts of machine

Machine bed, headstock , oil pressure head, drill bar support rest , drill box , sliding guide rail , Rack and pinion, coolant system , control system , electric cabinet, workpiece carrier etc. .

 

2.3.2 Workpiece clamping of Industrial drilling and boring machine

The manual three-jaw chuck on the headstock clamps one end of the workpiece, and the cone disc on oil pressure head automatically tightens the other end of the workpiece. .

 

 

2.3.3 Industrial drilling and boring machine control system

DELTA PLC /FANUC / SIEMENS /KND optional

 

2.3.5 Machine bed :

The machine bed is made of resin sand and normalised after casting. The bed adopts split structure, assembled with high strength bolts and positioned by cone pin.

Adopt double rectangular sliding guide rail, precision grinding, the guide rail surface is with high quenching hardness .

The helical rack which is treated by precision processing and quenching is mounted inside of machine bed ,used for cutting tool feeding transmission . The machine has large bearing capacity, good rigidity and stable transmission.

The V-shaped slant reinforced ribs are distributed inside of the machine bed , supporting strength is high, and it is not easy to deform; The outer wall of machine bed support the guide rail directly, so the guide rail could bear large cutting force, with good rigidity, not easy to deform and vibrate during machining, it is good for improving the processing quality and working efficiency of machine .

 

 

2.3.6 Headstock of Industrial drilling and boring machine :

Used to drive the workpiece to rotate, fixed on the left end of machine bed .

The gears are machined by precision grinding , gear surface is quenched by high frequency quenching, so that the gears can obtain high strength, high hardness, high wear resistance and high fatigue limit, and can withstand relatively large alternating load and shock load.

The external lubrication oil tank is used for circulating lubrication of gears and bearings, and a low liquid level alarm device is installed inside the oil tank.

Install a button board on the headstock box, which has functions such as spindle jog, feed forward, feed backward, and emergency stop.

 

 

2.3.7 Oil pressure head of Industrial drilling and boring machine

• Used for guiding the cutting tool, supplying cutting oil and supporting the drill bar .
• The rotary bearings of oil pressure head are installed inside of the oil pressure head box, with good rigidity and high rotation accuracy .
• The rotary seal is installed on the outside of the right end of the oil pressure head body for easy maintenance.
• The oil shield is push-pull structure,the oil retention is mounted under the oil shield ,so that the cutting oil can return the oil tank .

 

2.3.8 Drill box

• Used to drive the cutting tool to rotate, installed on the feeding carriage .
• The tool shank connection sleeve at left end of spindle for clamping the cutting tool.
• The chips removal bucket is installed at the right end of spindle for discharging the cutting chips .
• The gears are machined by precision grinding , gear surface is quenched by high frequency quenching, so that the gears can obtain high strength, high hardness, high wear resistance and high fatigue limit, and can withstand relatively large alternating load and shock load.
• The external lubrication oil tank is used for circulating lubrication of gears and bearings, and a low liquid level alarm device is installed inside the oil tank.

 

 

2.3.9 Drill bar support rest

• Used to support the drill bar ;
• Adopt a integrate structure with high rigidity , the support sleeve is mounted on it , which can absorb the impact, vibration, etc. generated during the processing.
• Install an automatic hanging mechanism. When returning the tool, the feeding carriage can automatically pull the drill bar support rest back to its initial position.

 

2.3.10 Coolant system of Industrial drilling and boring machine:

Mainly composed of Cooling pump,chips box,oil tank etc. ,to supply enough cutting oil for deep hole processing .

 

2.3.11 Feeding carriage

• Used for driving the cutting tool to move axially .
• Lubricate the sliding guide surface timely and quantitatively with an auto lubrication station .
• The button board is mounted on the carriage ,which has functions of drill box spindle jog,feeding forward, feeding backward, emergency stop.

 

2.3.12 Workpiece carrier

Used for workpiece pre-positioning .

The V-shaped frame on the workpiece carrier is manually lifted and lowered using a T-shaped screw.
