T2125 Deep Hole Drilling and Boring Machine

Adopting internal chip-discharging strategy, which handles diameter from Φ30mm to Φ100mm (drilling), our T2125 Series Deep Hole Boring Machine's drilling, boring and rolling functions are applicable to propeller, landing gear and ejection seat; various barrels in military use; heat exchanger pad in power plant; roller in metallic, all rotating parts for gas cylinder, fluid cylinder and spindle; pipes in casting and forging with accuracy of T17, roughness(drilling) of Ra12.5 and roughness(boring) of Ra6.3 as well as roughness(after rolling) of more than Ra 0.4. These Products' Boring Diameter ranges from Ф40mm to Ф250mm, with maximum length -10m. Our maximum Boring Machine can handle Boring Diameter – 1000mm(T21100).

Features of T2125 Deep Hole Drilling and Boring Machine

Accuracy of deep hole drilling and boring machine:

Drill hole: hole accuracy IT9-IT11, hole roughness: Ra6.3~Ra12.5um.

Rough bore: hole accuracy IT8-IT9, hole roughness: Ra3.2~Ra6.3um.

Fine bore: hole accuracy IT7-IT9, hole roughness: Ra1.6~Ra3.2um.

Rolling and pressing: hole accuracy IT6-IT7, hole roughness: Ra0.4~Ra0.8um.

Hole straightness: every meter less than 0.5mm.

Drill hole range: 30mm~120mm

Bore hole range: 40mm-1200mm (different model)

Drill max depth: 18meters

The body of T2125 deep hole drilling and boring machine is good in regidity, high accuracy. The spindle speed range is wide, infeed system is driven by AC servo motor, which can meet all kinds of deep hole process, the oil supply fasten device and workpiece clampling device adopts hydralic system, and show the pressure value, safety and reliable.

We can also make similar machines basing on the above machine, different length. We can make this kind of deep hole drillingand boring machines according to customers' requirement.

The machine is special equipment for machining deep cylindrical hole of work pieces. It can be perfectly suited for boring, through holes, blind and step holes in workpieces; Such as, apindle of various kinds of machines, many kinds of hydraulic oil cylinders and cylinders and drill collars in the gas and oil field.

It adopts BTA processing method, it can not only drill the deep holes, but also bore the deep holes. When drilling the workpiece, it adopts BTA chip remove method, that is: the coolant liquid arrive the drilling parts through oil supply device, the iron chips and coolant oil return to the drain back tank and chips removal device through the drilling bar hole. Through the above method to realize the drilling purpose.

When boring the workpiece, we adopts pull boring front chip removal method (pull the boring head go ahead, and remove the front chips by that way), the headstock spindle front equips chips removal device, used for boring and chips remove. When boring the workpiece, the workpiece rotary, so as to enhance the boring accuracy. The workpiece adopts double taper plate fasten position, workpiece fasten easily. Position liable.

Machine Main Frame

The machine consist of the following parts: Machine bed, heads stock, chuck bed, oil supply device, carriage, carriage infeeding system, support frame, boring bar support frame, boring bar fixing frame, cooling system, electric system, hydraulic pressure system, chips removal device.

The main parts, such as machine bed, carriage, tank body, oil supply device and support frames are all casted by super iron.

The machine bed rail width is 650mm, which consists of flat V rail. The guide rail is made of high-frequency quenching, which can ensure the high-strength, high-accuracy and high-rigidity of machine.

The machine's operation button station is in the front of the oil supply device, easy to operate. The oil supply fasten and workpiece fasten adopts hydraulic device, pressure is adjustable, the meter will show the pressure, safety and reliable. The oil supply spindle and machine spindle are in high condentricity, easy to change the guide sleeves.
