New 13” x 63” Knuth Servo-Universal Milling Machine with a Swivel Head

Knuth's rigid knee and column universal milling machine makes convention milling easier, more precise and efficient due to integrated electronics.  Offering a host of advantages and features listed below:

• 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 reliability
• Extremely rigid machine bed made of high-strength HT-200 cast-iron with heavy ribbing
• Precision-ground guideways with hardened surfaces for long term accuracy and wear resistance
• Precision spindle gears feature hardened and ground gears, and quiet operation
• Powerful 10 HP horizontal spindle, heavy top beam, and outer arbor ensure excellent machining results when using long cutter arbors
• Servo-conventional drives on all axes, infinitely variable with fast rapid feeds
• Preloaded ball screws on all axes ensure increased precision and lasting wear-resistance

Servomill - Highlights

• Control developed and built in Germany
• Positioning control for traveling pre-selected paths on all axes
• 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 axes can be controlled via joystick
• Integrated position indicator with glass scale

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 197 in/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 looseness (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 positioning 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 significantly more positions can be set up than on conventional machines
• 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

X.pos Plus - You will gain productivity, quality and comfort

• Default coordinates
• Hole circle pattern calculation
• Vibration filter feature
• Mm/inch conversion
• 8 display languages
• 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 interferences and maintaining low temperature levels.
• Background colors 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 linear and non-linear length correction is possible.
• Easy mounting, easy electric connection, and maintenance-free operation
