Condition: like new (used), Year of construction: 1993, functionality: fully functional, Dowel and slot mortising machine GANNOMAT JUNIOR 320 LBM Very good condition, like new; the machine comes from a very small joinery and was used only very little. The machine is in its original state and has only been cleaned, with no touch-ups to the paint. You can mill slots and drill dowel holes on two levels without having to reclamp the workpiece. 380V, 1500W Ncsdpfxoynv E Rj Aaaor Speed: 2800 rpm Year of manufacture: 1993 With this machine, you can mill slots, for example for lock cases and similar applications, or make all types of frame dowel joints, at right angles, butt joints, or mitred joints. Ideal for producing dowel joints in timber frame construction, furniture, door, window, and staircase manufacturing, as well as similar applications. By drilling on two levels, using the stops and indexing rails, and due to the machine’s design, dowel joints can be produced in a very short time, which makes the machine highly efficient. The machine requires a compressed air connection of 6 bar (air consumption is very low). Right-hand rotation. Mills and drills very efficiently and cleanly. Supplied with 2 angle stops (one center stop and one side stop, which can be used on either side), plus a mitre stop. On the front of the machine table, there is a 2000mm long stop rail with 2 flip stops; the stop rail can be shortened or extended if required. Workpiece clamping is done with 2 pneumatic clamping cylinders. Height adjustment between drilling levels is also pneumatic; the pneumatic switch is located at the front of the machine, ensuring rapid adjustment of the index positions and drilling levels. Equipped with a precision 12mm indexing rail, featuring a center index and 12 indices left and right. Can be quickly converted for slot milling; in this mode, the machine can be used without indexing, with 2 adjustable stops left and right, allowing for a maximum working width of 420mm. Maximum drilling hole height: 100mm Maximum drilling depth: 150mm with stop and scale Maximum workpiece height: 160mm Everything functions perfectly. The machine is personally delivered and demonstrated by us anywhere in Germany for €220.00, so you have no risk when purchasing. Delivery to Austria and the EU is also possible on request. The machine table is 870mm wide, 140mm deep at the sides, and 350mm deep in the center. Professional equipment, not DIY store scrap. Ready for immediate operation. With 2-jaw drill chucks up to 20mm. Very stable and durable construction. The precision guides with play-free ball bearing bushings are in excellent condition and move smoothly.
