The usage of the machine: the machine is a special equipment for 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. 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 Features specifications technical parameter T2225G/1 The range of boring diameter Φ40mm-250mm The height of center 400mm The range of Max. boring depth 1000-10000mm The diameter of chuck Φ400mm Workpiece clamed dia. of steady rest Φ50mm-400mm Spindle speed range and steps 70-1200r/min, three gears, 12 grades Feeding speed range 5-2000mm/min,3 gears, stepless Main motor N=30kW Feeding motor N=4.5kW servo motor Motor of oil pressure head N=4.5kW servo motor Cooling pump motor N=5.5kW n=1440r/min 4 groups 2 groups The rated pressure of cooling system 2.5Mpa Flow of coolant 100 200 300 400L/min
Optional scheme 1. The machine can be mated with N=37kw frequency converting spindle motor, then the spindle speed will change to 40-800rpm with 3 gears stepless speeds. 2. Both T2225G/1 are mated with a travel headstock with rotating boring bar and a 15kw motor so that the workpiece and boring head can be rotate oppositely, and the spindle speed of the travel headstock is 40-500rpm. 3. the machine can be mated with CNC system, e.g. SIEMENS 828D or FANUC oi mate or GSK or KND system or other system chosen by user..
