For reference only

 

1. Machine Brief:

 

1.1 Machine processing range:

Solid drilling diameter range ：25-100mm

Boring diameter range ：40-200mm

Workpiece OD range ：60-300mm

 

1.2 Machine function:drilling and boring.

Drilling：BTA drilling method, chip is discharged backward through the drilling bar.

Boring：Push boring method, chip is dispatched forward through the bottom hole of the workpiece.

 

1.3 Machine main structure:

 

1.3.1 Machine main components:

Machine bed, headstock, workpiece support rest , oil pressure head, boring bar support rest, drill box, slide rail, rack and pinion,coolant system, control system, electric box, center rest.

 

1.3.2 Workpiece clamping method:

The manual three-jaw chuck on the headstock clamps one end of the work piece, the cone on the oil pressure head automatically pushes the chamfer at the other end of the work piece.

 

 

 

 

 

 

 

 

1.3.3 Machine system: PLC controller

Z-axis: the drill pipe box is fed longitudinally, and the servo motor drives the rack and pinion mechanism through the reduction mechanism.

X axis: the oil feeder servo jacking the workpiece, the servo motor drives the rack and pinion mechanism through the reduction mechanism.

 

1.3.4 The machine bed, box body, pallet and other basic parts are made of high-quality cast iron precision casting. After the casting is completed, they undergo two aging treatments to eliminate internal stress, stabilize structure and size, and improve mechanical properties.

 

1.3.5 Machine bed:

The bed body was cast with resin sand and normalized treatment was carried out after casting. The bed body adopts a split structure, which is assembled together by high-strength bolts and positioned by conical pins.

Adopt double rectangular sliding guide, precision grinding, high hardness of guide surface quenching.

The bed is equipped with a bevel rack for the tool feed drive. The rack is precision machined and quenched. The machine tool has large bearing capacity, rigid foot and stable transmission.

V-shaped inclined bar is arranged inside the bed body, which has large support strength and is not easy to deform. The outer wall of the bed directly supports the guide rail, the guide rail can withstand large cutting force, the rigidity of the guide rail is good, and the processing process is not easy to deform and shake, which is conducive to improving the processing quality and efficiency of the machine tool.

The oil return tank is cast around the bed body, and the oil baffle is installed on the return oil tank, and the cutting oil on the bed body automatically returns to the cooling tank.

 

1.3.6 Headstock:

Used to drive the rotation of the workpiece, fixed on the left end of the bed body.

Manual 3 gear, stepless speed adjustment in the gear, with the servo spindle motor through the belt, gear box to drive the spindle rotation, headstock front assembly manual three-jaw chuck for clamping workpiece.

Gear precision grinding processing; The gear tooth surface is treated by high-frequency quenching, so that the gear can obtain high strength, high hardness, high wear resistance and high fatigue limit, and can withstand relatively large alternating load and impact load.

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

A button plate is installed on the headboard box, which has the functions of spindle point, feed forward, feed backward and emergency stop.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1.3.7 Center rest:

The center rest is used to support the workpiece; the three-point closed center rest structure has two rollers on the bottom and one roller on the top; the two rollers on the bottom are used to adjust the lateral position through a screw.
