Knuth Servomill 700

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 machine base in a proven design, and meticulous workmanship
• Variability via swiveling and moving top beam
• Perfectly adjustable dovetail guide on the X axis, and wide square guides in Y and Z direction
• High-precision preloaded ball screws on all 3 axes
• All guides are hardened and ground, and are supplied with oil by the central lubrication unit
• Cutter head swivels with pneumatic tool clamping and powerful 3.7 kW motor
• Infinitely variable spindle speed with back gearing and LED speed indicator
• Manual quill feed with micrometer depth stop allows for precise angular bores
• Large, swiveling control panel with integrated position indicator

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

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 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
• Linear and non-linear length correction is possible
• Easy mounting, easy electric connection, and maintenance-free operation
