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.
