2-axis CNC milling machine Servomill® UWF 900

universalcolumn typeSK40

Product overview
The versatile Servomill UWF with servo-conventional feed technology and a two-level swiveling cutter head is the top model of the Universal Milling Machine series. The series offers an extra-large work area and powerful main spindle drives. Electronic stops, electronic hand-wheels and additional milling functions provide many advantages of CNC production technology even without programming. Typical applications include toolmaking, manufacturing and training.

Highlights

• Large work area
• Servo-conventional feed technology
• Preloaded ball screws on all axes
• Electronic hand-wheels
• Universal cutter head with 2 swivel axes
• Infinitely variable spindle speed

Product details

• Integrated electronics simplify conventional milling while increasing precision and efficiency.
• New generation of conventional mills with electronics developed and made in Germany.
• User-friendly layout, higher precision and improved productivity versus traditional machines.
• Robust, torsion-resistant knee-and-column frame with a large working area despite compact overall dimensions.
• Console supported by an additional guide system for increased table load capacity.
• Work table runs in an oversized dovetail guide on X axis for excellent damping and fine adjustment.
• Box ways with wide support bases for maximum dimensional stability guiding console and top beam.
• All guides are hardened, ground and lubricated via a central lubrication system.
• The complete drive is integrated in the heavy top beam for efficient power transmission and low vibration.
• Universal cutter head swivels on two axes to position the cutter spindle at virtually any spatial angle and quickly to the horizontal plane.
• Robust 2-step gears, hardened and ground, provide a wide, continuously variable speed range and quiet, high-load operation.
• Powerful servo motors enable infinitely variable feed speeds and rapid feeds on all axes.
• Preloaded ball screws on all axes ensure precise, backlash-free positioning with minimal wear.
• Electronic spindle load indicator supports efficient use of machine and tool capacities and helps avoid overload.
• Electronic hand-wheels on all axes and joystick control allow smooth micro-control and operator comfort.
• Positioning control for traveling pre-selected paths on all axes; electronic fixed stops (3 positions per axis) with push-button convenience.
• Integrated position indicator with precision glass scale; X.Pos 3.2 display generation available.
• Standard equipment includes coolant system, LED work lamps and a selection of operating tools.
