SERVO MILLING MACHINE

Servomill® KB 1500

Integrated electronics allow for easier, more precise and more efficient conventional milling

• The Servomill machines represent a new generation of conventional milling machines
• All Servomill series are characterised by ease of operation, significantly increased precision and enhanced cutting performance
• The high reliability of all components used and their long service life significantly reduce maintenance costs and thus ensure increased availability

Design and Construction

• The Servomill® KB 1500 is characterised by its solid machine bed, on which the large machining table moves in the X and Y axes
• The heavily ribbed fixed machine column, guides the compact universal milling head with drive unit in the Z axis
• The entire construction is characterised by its rigid and generous dimensions, high-quality casting and careful workmanship
• The very wide flat guides of the Y-axis guarantee stability under high table loads
• X-axis with large dimensioned dovetail guide ensures high rigidity, load capacity, and tilt resistance
• In addition, this design offers excellent damping properties and the option of finely adjustable wear compensation, making it particularly suitable for heavy-duty machining tasks with high stability requirements
• The large table travel and the large table clamping surface enable the machining of large individual workpieces or several workpieces in alternation
• The milling head unit runs on long flat guides and is additionally supported by a counterbalance
• A stable counter support is included in the scope of delivery for horizontal milling work with long milling arbours

Main spindle and drives

• For high torques, the spindle speeds can be regulated in two gear stages via an inverter
• The universal milling head is characterised in particular by its stability and smooth running
• The angle adjustment is infinitely variable manually in the 90° and 45° planes
• This enables precise adjustment of the main spindle in freely definable spatial angles and simple swivelling into the horizontal
• The counter-holder guide is mounted for the use of long milling arbors, enabling high removal rates or simultaneous machining with several tools

Feed

• Powerful servomotors enable infinitely variable feed speeds and rapid traverse in all axes
• Preloaded recirculating ball screws in all axes guarantee precise, smooth and low-wear positioning without backlash and a long service life
• In the Z-axis, weight compensation ensures smooth traverse

Equipment

• The machines are equipped with a comprehensive range of accessories as standard, such as LED work lighting and an extensive tool set with milling arbours and collets
• The coolant system is integrated in a large, separate and mobile tank and is easy to maintain
• The control panel is mounted on a long boom and can always be optimally positioned by the operator
• The centralised lubrication system reliably supplies all lubrication points with lubricant, making daily maintenance easier

Your Advantages

• Easy to use: intuitive operation - practical layout of control elements and streamlined function
• Automatic feed on all axes infinitely variable
• 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
• 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 drive technologie

• The axes are moved by high-quality servo drives that implement your handwheel movements with the precision and dynamics of modern CNC machines
• Reliable, maintenance-free high-volume technology
• High rapid traverse speed reduces non-productive times

Ballscrews in all Axis

• 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 Operation

• Maximum operator comfort for axis movements
• Easy handling during sequential processing

Electronic Bedstops

• 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

Electronic Spindle Load Display

• Assists the operator in the most efficient utilization of machine and tool capacities
• Reliable indicator helps avoid damages caused by overloads
