Manual Bridgeport-Style Knee Mill
DMV 250 VS • 305 VS • DMVH 305 VS
Manual Bridgeport-Style Knee Mill for prototyping, repairs, and low-volume production with drilling and milling head. DMVH model also offers horizontal and vertical spindle in a heavy-duty knee mill. The infinitely variable speed control is paired with quiet V-belt drive operation. The head swivels left/right/back/forward ± 45° and rotates the upper arm around the column 360°. The automatic spindle sleeve feed has 3 steps and micrometer depth stop. The automatic spindle switchover and spindle braking via hand lever combine to make this a great V-belt manual Bridgeport-style knee mill.
All models of these Manual Bridgeport-Style Knee Mills include 3-axis digital readout (DRO) and the spindle material is SCM415 full hardened through carbonizing heat treatment. The NST#30/R8 spindle features 3HP variable speed motor (250 VS) and the NST#40 spindle with 5HP variable speed motor (305 VS) (inverter motor is an available option). The spindle quill drive box is transmitted by ballscrew for better precision. Essential castings are made of high grade of Meehanite cast iron, which has been stressed and relieved to provide a rigid machine structure. The standard table is 10”x54” table, hardened and ground with the T-slot precision ground to exact tolerance. Precision ballscrews on X &Y axes.X&Y slideways and gibs are coated with Turcite-B to provide smooth and wear resistant surface. The 1:2 ratio timing belt pulleys on the XY axes increase drive torque. Box way design on Y & Z (knee) axes leads to better rigidity. (305 VS) Lifting screw diameter 38mm assures the stability of the knee while milling. (305 VS)
