hapfo® CHALLENGE-7000

For the production of large series with the highest demands on accuracy, as well as for highly complex parts, the hapfo CHALLENGE-7000 offers all the technical advantages that characterize a powerful CNC fully automatic wood turning machine. The CHALLENGE-5000 can turn, mill, flute, drill and sand. Ideally suited for large series and parts ready for painting.

Center width: 1,750 mm
Copying length: 1,450 mm (calculated with long hexagonal driver, long travelling center punch and four-jaw steady rest. When using the ring steady rest, a further 120 mm must be deducted)
Copying diameter: max. 400 mm (without magazine operation)

Special features of the hapfo CHALLENGE-7000:

• Headstock and machine bed made of high-quality gray cast iron
• Backlash-free bearing of the hollow spindle (suitable for vacuum connection) with thread M 45 and inner cone MK 4.
• Bearing of the support on linear guides with servo motor drive
• Tailstock in heavy cast iron design with eccentric quick clamping and cone MK3
• thin parts possible due to leading steady rest, when using the ring steady rest with pre-cutting steel, planing of the raw material is not necessary
• optional turning steel swiveling device for continuous cutting even with balls and grooves
• optional belt grinding unit with PC control for point and flat grinding on round profiles. Turning and grinding in one operation
• Simple and practice-oriented operation with special turning functions
• Low training effort due to the use of simple 2D CAD software
• Production of several parts in "bar mode" possible
• Fluting can be produced in any pitches and inclinations with the milling unit, which can be swivelled and adjusted in height in several directions.

Drive:
7.5 kW three-phase motor with frequency converter regulated and controllable via the program.
Spindle speed range from 0 to 3200 rpm.

Magazine:
The newly developed magazine combines the experience gained from previous generations with some interesting and extremely useful innovations. It is self-centering and can clamp both rectangular and round raw material. By using the rollers in the gripper, the system can also be used as a program-controlled support steady rest, which significantly reduces production time, especially for slim parts. The internal grippers also allow warped raw material to be utilized more efficiently. Operation can be carried out completely from the front. The finished parts are ejected from the front. The minimum dimension of the cross sections is 20 mm. Automatic operation is possible up to 100 mm. The grippers can also be used as insertion aids up to a cross-section of 130 mm. The workpiece length can be adjusted between 140 mm and 1300 mm can be infinitely adjusted.

Software and programming
Standard software MegaCAD LT to create the contour
Data import and export in all common formats
All additional parameters are entered and saved in the machine software.
All menus are graphically supported and marked with symbols. All important information such as speed, feed rate, positions of the axes or the current program progress is displayed at all times. It is also easy to operate the magazine manually.

Handwheel for manual/automatic operating mode
A handwheel with display is optionally available to indicate the selected operating mode. In manual mode, this allows all axes to be positioned quickly and precisely. In automatic mode, START/PAUSE/STOP as well as speed and feed can be controlled continuously at any time.

Dimensions (standard): L= 3550 mm (4600 mm with sliding door open),  W=2400 mm, H= 2200 mm
Weight (standard): approx. 1600 kg depending on version
