BCK6640 Slant Bed CNC Lathe Machine Product Highlights
- The BCK6640 CNC lathe has an inclined bed. It can do four-axis linkage (C, Y, X, Z) and has a precise indexing function in its servo spindle. It can easily process complex parts on the same machine tool. It can side mill, drill, and tap, and interpolate curves. This reduces time spent on secondary processing, improving accuracy and saving on secondary processing costs.
- The Y-axis has a turret. It can greatly improve the accuracy and efficiency of drilling, milling, and tapping side parts.
- The Y-axis and the spindle are kept at 90°.
- The turret’s weight is shared by the X and Y axes. Its center of gravity is always at the central bearing of the machine tool. This reduces wear on the X and Y axis screws and the guide rail. It also makes the turret move evenly.
- It can process complex workpieces like linear and oblique cylinders, arcs, and various threads, grooves, and worms. It has compensation functions for linear and circular interpolation. This has greatly benefited the mass production of complex parts.
