1 CK-2900K MACHINE NAME AND MODEL: train axle CNC double turret lathe 2 .Application: used for turning journal surface,shoulder surface and arc surface of locomotive axle except the clamping section. 3 QTY:.1set 4 :,.Delivery way: completed machine( with fixture and processing program) and acceptance, tools and fixture selection. 5work-piece introduction 5.1 .Name: all kinds of locomotive axle 5.2Axle description:
two end finished in two end milling machine, the endface milling, center hole, thread hole and endface round milling.
Work-piece length:1750-3000mm
Max.work-piece diameter:320mm
Work-piece check clamping diameter;130-200mm
The steady rest clamping diameter: 130-320mm 5.4Installation, positioning, and clamping position: 45-degree inclined bed, double spindles, double drives, with directional position mechanism, self-centering chuck clamps the shaft end that has been milled at both ends, and the flat head in the right end chuck pushes The rod supports the shaft body to the left so that the left end surface is close to the axial positioning end surface of the left chuck. Each chuck has two V-shaped pre-positioning blocks, and the axle shaft can slide axially on the pre-positioning blocks. The machine is equipped with a hydraulic self-centering steady rest with servo-controlled axial movement. Auxiliary support is provided in the middle of the axle to ensure cutting rigidity during machining, and is suitable for rough turning with large allowance. 6 application environment 6.1 power supply: 3phase,voltage 220V/380/415/440V/575V±10%;frequency 50/60HZ±2% 6.2 humidity: relative humidity≤95%;emperature0-45ºC 6.3 work area:Not more than 8000mm×3000mm×2800mm(LXWXH) 6.4 Penumatic supply:0.4-0.5MPa 7.processing procedure
After the machining is completed, the protective door is automatically opened, and the axle is taken out manually with a special spreader and moved outside. The door is closed, and the flat-headed push rod in the right end chuck pushes the shaft body to the left to make it move left on the V-shaped pre-positioning block, and the left end face is close to the axial positioning end face of the left chuck. The fixture is automatically centered and clamped, and double turret cooperates with the center frame to perform processing work. After processing, the main shaft is oriented to stop, the clamp is released, the protective door is opened, the axle is manually taken out, and then the axle to be processed is put into the chuck, and then left, the protective door is automatically closed, and a new processing cyclestart. The feeding method can also be automatically put in and take out the work-piece from above the center of spindle through a gantry crane or a manipulator. The machine has a work-piece loading and unloading guiding mechanism to ensure that the work-piece is accurately placed in the chuck.
