Features of Small 4 Axis CNC Vertical Milling Machine
1. The bed base and the Y-direction guide rail are designed as one piece, and they are used for rear drainage. Four shock-absorbing pads are used for the overall leveling of the machine tool, and they are locked with nuts after adjustment.
2. The X-direction is designed as a large worktable and a small slider structure, that is, the X-axis motor moves with the worktable. The T-slot of the worktable is a through-slot.
3. The movement speed in the Z direction is slow, there is no counterweight, and the Z direction adopts a large torque motor (or a matching mode with a small counterweight).
4. One end of the X, Y, Z three-axis motor seat is equipped with a special bearing for the lead screw (back-to-back), and is locked with a precision round nut for axial positioning. The other end of the lead screw is a floating structure without support. Bearing size is 20 × 47 × 14.
5, X, Y, Z three-axis screw with 2506 specifications.
6. The spindle unit is purchased from BT30-100 (self-made spindle unit can be used). 1:1 transmission.
7. It is recommended to use a 5Nm 110-frame motor for X, a 6Nm 110-frame motor for Y, and a 7.7Nm 130-frame motor for Z.
8. There is a tool magazine installation joint surface on the side of the column, and the machine tool can be installed with BT30-12 bucket hat type tool magazines.
