This our T2120 CNC deep hole drilling and boring machine is specially designed for processing cylindrical workpiece ， it can achieve inner hole drilling , boring , expanding , roller and burnishing , its not only processing through holes, but also can process stepped hole, blind hole. Cutting tool (rotating) for feeding when the workpiece drilling hole , the cutting fluid through oil feeder or boring bar end into the cutting area for cooling and lubrication cutting and And take away the cutting chips . Oil feeder supply the cutting fluid when drill hole , adopt BTA inner chip removal processing form . Oil feeder and boring bar inside supply the cutting fluid, use the forward ( machine head ) take away the cutting fluid and chip removal processing .
This deep hole drilling and borning mafchine can optional for the drilling box to achieve the workpiece, tool rotation double, single action can also meet the needs of different situations processing technology, the processing efficiency can fully guarantee the processing quality with under the condition to reduced speed of the workpiece (not suitable for high-speed rotation of the workpiece),
According to the actual needs of the main gear can be flexible choice of processing technology and with widely range of application..
This machine mainly component is the machine base , headstock , drilling bar box , (optional) cartridge body, feeding plate, oil feeder , cooling parts, chip removal device, workpiece center frame, hydraulic system, drilling and boring bar bracket , motor gear and electrical system
