KNUTH VDM 800S VERTICAL MACHINING CENTER

Technical Description

The KNUTH VDM 800S is a heavy-duty vertical lathe engineered for precision machining of large-diameter workpieces and components requiring substantial weight capacity. This machine features a single main spindle with a maximum turning diameter and length of 31 inches, accommodating workpieces up to 2,640 pounds. The 28-inch chuck diameter provides robust clamping capability for demanding applications. Operating at a speed range of 10-315 RPM, the machine delivers maximum spindle torque of 7,376 foot-pounds, ideal for heavy machining operations. The five-axis configuration provides versatility with X1, Z1, and W-axis travels of 22, 24, and 23 inches respectively on the upper support, plus X2 and Z2 axes on the independent side support for outer contour machining. Dual tool carriers accommodate up to nine tools total, enabling simultaneous use of two cutting tools for enhanced productivity. The machine incorporates a high-torque servo motor for infinitely variable feed control, with X and Z-axis feeds ranging from 0.0315 to 3.3858 inches per minute. Rapid feed rates reach 71 inches per minute on both upper and side supports. The 29.5 HP main drive motor combines with auxiliary motors rated at 4.3 and 4.29 HP for X and Z-axis operations. A fully enclosed housing, automatic central lubrication system, and standard 3-axis position indicator ensure precision and reliability. The machine weighs 14,300 pounds with overall dimensions of 193 x 138 x 164 inches, requiring proper facility infrastructure and handling equipment.
