Sharp Industries Vertical Bed Mills
- Heavy duty vertical bed mill equipped with geared head spindle and massive hardened and ground bed ways for heavy milling
- The vertical column is made out of box shape high tensile strength casting reinforced with honeycombed ribbings. It offers excellent vibration dampening features and great mechanical and thermal stability.
- The saddle and vertical head travels on hardened and ground box ways that offer maximum rigidity. All top, front, rear reference surfaces and T slots are precision ground to exact tolerance.
- The vertical head is equipped with a #50 fixed quill spindle for heavy duty milling.
- Besides a manual coarse and fine feed on the vertical head, it is also equipped with power feed for easy positioning. A tri-lever handle mounted in the front for easy operation performs manual rapid movement of the head.
- A separate pendant control performs all the spindle operations, coolant and power drawbar operations .
- The unique sliding saddle base design allows easy movement of the entire 23” of the cross travel, manually or by power.
- The table is equipped with a double nut backlash eliminator, which adjusts the backlash on the table travel when the screw and nut start to wear out.
- The automatic lubrication system lubes the table and saddle ways.
- The extensive vertical head travel along with various feed rates offer capability for precise boring operations.
- A horizontal milling head (5 HP, #50 taper) is installed on the side of the vertical column on Model KMA-3H. It travels on precision ball screw with AC servo drive.
