Machine Details

Knuth Servomill ufm8v

Conventional milling, now easier, more precise and more efficient due to integrated electronics

  • The Servomill represents a new generation of advanced milling machines that are operated like a conventional machine
  • This machine features a user-friendly design, significantly higher precision and increased machining capacity
  • Very high reliability and long service life of all components ensure drastically reduced maintenance and increased availability
  • Rigid frame design with wide guideways and travels
  • Servo-conventional drives on all axes, infinitely variable with fast rapid feeds, synchronized with spindle speed
  • Preloaded ball screws on X, Y and Z ensure high precision, low maintenance and low wear
  • All gears and guideways are hardened and ground
  • Swivelling vertical cutter head, pneumatic tool clamping and powerful 5.5 kW motor
  • 2 gear steps for a wide speed range, infinitely variable up to 5000 rpm, and high torque at the spindle
  • Horizontal spindle motor with 7.5 kW

Servomill - Highlights

  • Control developed and built in Germany
  • Positioning control for traveling pre-selected paths on all axes
  • Constant cutting speed with feed speed based on spindle rpm
  • Zero backlash preloaded ball screws
  • Servo-motors on all axes, infinitely variable feed, rapid feed, and speed control
  • Electronic spindle load indicator
  • Electronic hand-wheels on all axes
  • X, Y and Z axis movement via joystick technology
  • Integrated position indicator with precision glass scale

Your Advantages:

  • Easy to use: intuitive operation - practical layout of control elements and streamlined function
  • Automatic feed on all axes and infinitely variable rapid feed
  • With speeds up to 5000 mm/min
  • Set limit stops on any axis with the push of a button - 3 stop positions per axis can be stored
  • More precise: operated via electronic hand-wheels - axes are powered by high-quality servo drives that translate your hand movements with the precision and dynamics of modern CNC machines
  • More reliable: drives, spindles, and measuring systems are totally enclosed or mounted in protective enclosures and virtually maintenance-free
  • Electronics - made in Germany
  • More capacity: this machine only uses premium drive components that are designed for continuous operation
  • Maintenance-free: no regular maintenance needed for the entire feed drive
  • Advanced Feed Technology:
  • Axes are powered by high-quality servo drives that translate your hand movements with the precision and dynamics of modern CNC machines
  • Reliable, maintenance-free mass production technology
  • High rapid feed rate for reduced machine down-times
  • Ball screw drive on all axes:
  • Considerably less errors due to loseness (backlash), resulting in significantly higher precision
  • Significantly reduced friction, no stick-slip effect, reduced heat buildup, minimal wear
  • Electronic hand-wheels:
  • Micro-control via electronic hand-wheels offering the same handling and postioning as with a conventional machine, just smoother and more precise
  • Joystick control:
  • Maximum operator comfort for axis movements
  • Easy handling during sequential processing
  • Electronically controlled fixed stops:
  • Set 2 limit stops at 3 positions on each axis by the push of a button - these buttons are grouped around the feed switch for intuitive control
  • This ensures high repeatability during coordinate drilling or pocket cutting, and siginificantly more positions can be set up than on conventional machines
  • Constant cutting speed:
  • The feed rate is infinitely variable and can be coupled with the spindle speed in a selectable feed-per-spindle revolution ratio in the range of 0.01 to 1 mm/R
  • This ensures a constant feed-per-tooth value and simplifies the operator’s task of optimizing the machining operation
  • Electronic spindle load indicator:
  • Assists the operator in the most efficient utilization of machine and tool capacities
  • Reliable indicator helps avoid damages caused by overloads

  • Calculator function
  • High-resolution display with excellent legibility
  • State-of-the art electronics and a very robust, completely sealed enclosure ensure maximum safety and optimum production conditions
  • A major focus during the development and selection of electronic components was the achievement of maximum resistance against external interference's and maintaining low temperature levels
  • Background colours of the display can be changed as required or desired
  • The keyboard membrane is highly resistant and yet very comfortable to touch
  • The display also provides a key to toggle between radius and diameter
  • The axis position is maintained when the display is turned off
  • Graphical support with residual path display and sketch drawing
