Servo-conventional milling machine

Transcription

1 Universal Milling Machine Servo-conventional milling machine Control developed and built in Germany Positioning control for traveling pre-selected paths on all axes Constant cutting speed, whereby the feed speed is based on spindle speed 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 Travel X-axis up to 55 inch Y-axis up to 27 inch Z-axis up to 20 inch

2 Servo-Conventional: Intuitive operation, extensive functionality, and proven machine design combined with the precision of advanced CNC technology Servo-Conventional Drive Technology - rigidity, flexibility and large workspace Sturdy and torsionally rigid construction with dovetail guide on X and Y axis, wide block guides on Z axis Large work table and large travel ranges on all axes All guides are hardened and ground, and lubricated via a central lubrication system Universal swivel head can easily be turned into the horizontal plane Infinitely variable feed speeds and rapid feeds, can be synchronized with the spindle speed by the push of a button Preloaded ball screw with zero backlash for smooth and precise feeds 2-step gearbox with hardened DESCRIPTION and ground gears ensures a wide infinitely variable speed range Integrated position indicator with glass scale 10 shown

3 Joystick with visible stops 3-axis position indicator DESCRIPTION Advantages of this machine design Simple: Intuitive operation - practical layout of control elements and streamlined functions Automatic feed on all axes, infinitely variable Rapid feed up to 197 inch/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 Feed control with infinitely variable setting in 3 ranges Spindle speed control for 2 speed ranges 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

4 Control cabinet and control modules - MADE IN GERMANY Servo-motor and preloaded ball screw DESCRIPTION Advanced Feed Technology Axes are powered by high-quality servo drives that translate your hand-wheel 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 to 0.04 inch/rev 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 Position indicator with glass scales The perfect indicator for a servo-conventional machine: Easy to operate and advanced function
