Krüsi CM40

KRÜSI Chalet Construction Machine / Log House Production Plant Type CM 40

Manufacturer: Krüsi Maschinenbau AG, CH-9105 Schönengrund AR
Year of manufacture: 1996

Condition: Good, technically inspected and cleaned / ready for operation

Functional Principle:
Processing of construction timber for chalet or log house manufacturing.
Beams can be processed in one pass:
- Cross-cutting
- Horizontal and vertical milling of tenons/grooves in one clamping
- Drilling
- End-groove milling

Workpiece:
- Max. cutting height: 200 mm
- Max. cutting width: 250 mm

Robust welded steel frame construction. The machine (horizontal and vertical milling unit) features 4 special milling motors, with hardened and ground guides for maximum machining accuracy. The carriage is guided by dust-protected and preloaded ball bearing rollers.

Working range up to 200 x 250 mm. Fully operational, with contactor control, motors protected by thermal relays. Electrical equipment for 380 V, 50 Hz, with protective covers, central connection for onsite chip extraction, with 2 eccentric clamps, without milling tools (rebate cutters).

With hydropneumatic horizontal and vertical feed electronically controlled together with the start of the milling motors. Rapid traverse and feed continuously adjustable. Fully wired and installed, including air maintenance unit.

Workpieces thicker than 14 cm must be machined in two passes. Such pieces must be repositioned after the first cut by the amount of excess thickness for re-machining. Machine guarding covers with gas spring counterbalancing over moving parts.
