1 Main structural features of the machine tool: (frame drawing of machine tool)
1. The table is fixed along the X axis.
X-axis drive: AC servo motor drive ball screw drive, drive the table movement, achieve X-axis linear motion.
Guideway form: Taiwan Shangyin two strip five Type 5 roller linear guide , per installation four Sliders 。
2. Y axis: the milling head slide plate moves reciprocally along the beam guide rail.
Y-axis drive: AC servo motor drive, ball screw drive.
Guideway form: Taiwan Shangyin 2 Type 55 roller linear guide.
3. Z axis: milling head ram moves vertically and reciprocally along the slide guide rail.
Z-axis drive: AC frequency conversion motor is used to drive the spindle box to move up and down through the ball screw, and a parallel screw counterweight is added
Guide rail form: T-type RAM 。
four 、 Milling head: the main milling head adopts eighteen point five KW fanaco original motor, the highest speed up to 6000 rpm.
5. Large pieces: The large parts of the machine tool include bed, worktable Column 、 , beam Milling head slide plate, milling head RAM Milling head 。
CNC gantry milling machine large-sized object Resin sand molding, high strength and high quality iron castings are used. The large blank is heat aged Secondary tempering of rough machining In order to eliminate the internal stress; after rough machining, carry out sufficient aging treatment to eliminate the processing residual stress; finish machining on the CNC gantry boring and milling machine adopts the way of free clamping for high-speed light cutting, so that the machine tool has good rigidity and accuracy retention. |
