Cross Joint Milling Machine
make Stegherr
type KSF-2/E

built 2007

Special milling machine for the efficient manufacture of cross joints with electronic positioning unit (standard fence length for work pieces up to 2200 mm).

Cut-outs are made by an upper and lower, milling by a third unit in one work process.

The feed speed of the milling group is infinitely variable. The total milling group runs in the clamped static work piece.

The upper and lower tool kit is individually height adjustable. This enables a fast changeover of the machine to another wood thickness.

The tools are driven by two 3-phase motors with each 1,1 kW.

Distance data of the requested cut-outs and their quantities are entered and stored in the positioning control we well as the total number of the work pieces to be processed. Programming of the positioning control is possible without any special skills.

Foot control
1 m fence extension
4. milling unit

This special grooving unit enables to process vertical and horizontal cross joints without turning them by 180° and guarantees that the visible side can be milled absolutely tear-free.
Quick adjustment for upper milling unit.

For single-sided milling into frame profiles (milling from bottom). This means for the frame (milling from inside) that the upper milling unit, which is required for milling of the cross joints, has to be pivoted off.
This pivoting of the upper milling unit is done automatically by the programme when frame parts are processed.

Additional saw unit with horizontal stroke for +45707-45° cross cutting of the frame parts (mitre cut).

Counter system with 2 counter-rotating spindles incl. servo axis.

- 2 milling bearings, stacked on top of each other, for holding a right and a left counter milling cutter – drive of each bearing: approx. 1 kW, approx. 5000 rpm

Adjusting slide for the adaptation of different tool diameter at various counter profiles.
Both cutter bearings are positioned on a linear slide moving horizontally.

The milling units can be moved forward and backwards by a pneumatic cylinder
This enables the adjustment of the cutter to the requested profile depth without further problems. When having 2 profile depths with the same cutter, they both can be controlled by the programme.

Length detection of the inserted work pieces in the machine with optimised execution.
In order to detect different work piece lengths without data input the machine has an integrated length detection that finds out
- how long the inserted work piece is
- if a work piece processing can be made or which processing is carried out

Incl. tool kit for 3 milling units, consisting of:

2 two-part adjustable profile cutters and 1 adjustable groove cutter in FIM cutting tip design (incl. 1 setting gauge with dial gauge), adjustment range 4,2 - 7,5 mm

1 set spare tools with adjustable cutting tip, consisting of:
each 6 pcs. for upper and lower profile cutter and 8 or 12 pcs. for groove cutter for adjusting range 4,2 - 7,5 mm (= 24 pcs.)
spare grooves for 4. milling unit (consisting of HM saw blades)
1 set counter tools, consisting of 2 pcs. HM cutter

400 V / 3 phases / 50 cycles

The machine is still in operation.
