Krüsi CM40

KRÜSI chalet building machine / log house production line type CM 40
Manufacturer Krüsi Maschinenbau AG CH-9105 Schönengrund AR
Year of manufacture 1996
S/N 431

Condition: good, technically checked and cleaned / ready for operation

Functional principle
Machining of timber for chalet construction / log house production
The beams can be processed in one pass

- cutting to length
- horizontal- and vertical milling of the necks / grooves in one clamping
- drilling
- milling the face grooves

workpiece:

- Cutting height max. 200nn
- Cutting width max. 250mm

Robust construction in welded design.
Machine (horizontal and vertical milling unit) with 4 special milling motors,
with hardened and ground guides for highest machining accuracy.
Carriage guided by dust-protected and preloaded ball-bearing rollers.

Working range up to 200 x 250 mm. Completely ready for operation, with contactor control,
motors protected by thermal relays.
Electrical equipment for voltage 380 V, 50 Hz, with protective bonnets,
central connection for on-site chip extraction, with 2 eccentric clamps,
without milling tool (folder).
With hydropneumatic horizontal and vertical feed electrically controlled,
together with the start-up of the milling motors.
Rapid traverse and feed infinitely adjustable. Completely wired and installed, including air maintenance unit.
Stains with a thickness of more than 14 cm must be processed in two tensions.
Such patches have to be re-milled by the amount of the extra thickness.
Machine protection bonnets over the moving parts with gas spring weight compensation
