KRÜSI log house production line type CM 40

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
