T2120GThe usage of the machine: the machine is a special equipment
for drilling and boring deep hole of cylindrical workpieces. While
boring, the oil supplied from the oil pressure head take the metal
chips from the cutting area to the lantern and chip converyer in
the front of the headstock, and drilling adopt internal metal chips
remving method (BTA method), the oil supplied from oil pressure
head remove the chips from the cutting area to the chips receiver
in the back of the machine through the innner hole of the drilling
tube. The machine is controled by PLC, and the feed of the oil
pressure head and carriage is controled by the servo motor, The
feeding rack installed in the middle of the bed guideway guarantee
the requirement of feed accuracy and rigidity for the long travel.
The protection guard installed on both sides of the bed and
overground oil tank improve the working environment. The machine
can be mated with automatic or manual telescopic tool so as to
improve the machining efficiency greatly.This is a easy operating,
high efficiency and environment protective deep hole drilling and
boring machine.Main Specifications and

mated with N=37kw frequency converting spindle motor, then the
spindle speed will change to 60-1200rpm with 3 gears stepless
speeds.2. T2120G/1 is mated with a travel headstock with rotating
drilling bar and a 15kw motor so that the workpiece and drilling
head can be rotate oppositely, and the spindle speed of the travel
headstock is 40-500rpm.3.the machine can be mated with drilling
small holes device which can drilling 20-40mm holes.4. the machine
can be mated with CNC system, e.g. SIEMENS 828D or FANUC oi mate or
GSK or KND system. /* March 10, 2023 17:59:20
