EUMA-Spinner Corporation

• High speed high precision linear guideways.
• High speed directly driven spindle (ISO 40/12,000 rpm).
• 13KW powerful motor drive.
• Rapid traverse (X/Y/Z) 40/40/40 M/min.
• Speedy tool change (T-to-T) in only 2.5 seconds (1.3 seconds optional).

High Rigidity

• Maximum structural rigidity is achieved through ruggedly constructed cast iron, extra wide slideways and oversized column.
• Ram type spindle stock combined with shortened distance from spindle to column surface, assure powerful cutting and high machining accuracy.

High Speed, Powerful, Direct Drive Spindle

• The direct drive spindle features minimum vibration, minimum noise and minimum heat generation. This assures hight accuracy for machining and rigid tapping.
• The spindle is driven by a powerful 13 KW motor. It provides 12,000 rpm (optional 15,000 rpm) high speed running. The spindle is 3-point supported by 3 pairs of angular contact ball bearings, assuring high rigidity, high precision and high cutting load resistance. The spindle is ideal for both high speed precision machining and heavy duty machining.
• The spindle stock features a labyrinth structure combined with air blast device to fully prevent cutting fluid and dust from entering. This also ensures the spindle accuracy and its long service life.

High Efficiency

• The arm type ATC is driven by a cam mechanism for fast tool chanaing whick is accomplished in only 2.5 seconds (tool to tool). 1.3 seconds tool change time is optional.
• Rapid traverses on X/Y/Z axes are 4U M/min to shorten non-cutting fime and upgrade efficiency.

• The chip flushing device (standard equipment) has coolant nozzles mounted at both sides of the base. The powerful coolant flushes chips to the chip auger and then the chips are delivered to the back side of machine. It saves cleaning work for added efficency.

High Precision

• High precision linear motion guides feature minimum friction and zero backlash in each direction, and they are full load resistance. Lifetime rigidity, dynamic stability and positioning accuracy are guaranteed.
• The precision class C3 ball screws are pre-tensioned for upgrading the rigidity of the servo system. THis avoids positioning displacement caused by thermal expansion of the ball screws while also ensuring machining accuracy.
• 3 axes ball screws are directly driven by AC servomotors and coupled through high performace, high torque and high precision couplings. They fully avoid flexible deformation while upgrading positioning and repeatability accuracy under a heavy load condition.
• The Z-axis has no counter-balance system but is directly driven by a powerful motor. If provides extremely smooth high speed motion and high response on the Z-axis -also ensuring high machining accuracy and high speed drilling and tapping operation.
