When processing large-diameter shaft hole, the traditional craft method for processing drilling and boring will make a lot of raw materials into chips wasted. To meet market demand, we develop T2180 deep hole boring machin (trepanning machine).
T2180 deep hole boring machine (trepanning machine) is mainly used for drilling and boring deep hole for heavy duty parts with large diameters. In order for adapting to various technical demands, T2180 deep hole trepaning machine is equipped with drilling and boring box. The workpieces and cutting tools can be rotated. It adopts BTA method for drilling and push-boring method for boring. The oil is supplied by oil carriage or from the bottom of the boring bar. The manufacturing methods can be chosen with reference to specific requirements in different industries.
Accuracy of the T2180 Deep Hole Trepaning Machine
Drilling: aperture precision IT9-10. Surface roughness: Ra6.3-12.5.
Rough boring: aperture precision IT9-10. Surface roughness: Ra6.3.
Sleeve material: aperture precision IT9-10. Surface roughness: Ra6.3-12.5.
Fine boring: aperture precision IT8-9. Surface roughness: Ra3.2.
Roll: aperture precision IT8-9. Surface roughness: Ra0.2.
The processing hole straightness: less than 0.15/ 1000mm.
Processing of exit holes deviation: less than 0.5/ 1000mm.
The body of T2180 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.
