The Gemini 100-3 automatic saw is the latest evolution of the famous Gemini 80-2, sold in hundreds of specimens around the world. The Gemini EVO 2018, the Gemini 100-3, maintains intact the strengths of the traditional machine and further improves the features of speed, strength and precision which have always been peculiar to this model.
The cutting line can be integrated with full automatic deburring/chamfering units, marking units, washing machines and any kind of control, such as lenght control, Eddy Current control, demagnetising process as well as full automatic stacking units.
The saw can cut in single (max diameter/side 100mm), double cut (vertical, max diameter 50mm) and triple cut (vertical, max. diameter 30mm) tubes and/or bars both with HM blades and HSS blades.
The Gemini 100-3 is available with cutting heads for steel, brass, ecobrass, ALU and copper and it is conceived in order to grant the highest productivity.
The frame consists in a single block, machined on the machine tools; the weight of the machine has been increased by 650kg, and now reaches the weight of 3.500kg, thus contributing to the stability of the machine, which means precision of the cut, longer tool and machine life and reduced tool change times.
Cutting head for STEEL:
Cutting head transmission with hardened and grinded helical gears, including blacklash recovery through electromagnetic powder brake; a card manages the braking system, which is not affected by the microlubrication dust;
New design sawblade guide with hard metal covered plates, further improved in order to make the sawblade change easier and quicker;
The saw can work with both HSS and HM one way sawblades; range of Ø275÷370mm (according to the diameters available on the market) with the following options:
32-40 (40 with ring; 4x10x50-4x11x63)
40-50 (50 with ring; 4x11x63- 4x14x80).
The following motors are available for STEEL:
Motor 11 kW – Sizing 132 (47-297 rpm/). Continuous speed variation through inverter.
Siemens motorspindle – air cooling - 15 kW (32-275 rpm/).
Cutting head for BRASS/ECOBRASS/ALU:
Spindle with preloaded bearings.
Sawblade guide with air bearings, including two jaws in order to avoid the set-up of the machine when changing the sawblade diameter.
Sawblade Ø250÷360mm with the following fixing options:
32-40 (40 with ring; 4x10x50-4x11x63)
The following motors are available for BRASS, ECOBRASS/ALU:
Motor 9,25 kW – sizing 132
Motor 11-15 kW – sizing 160
Continuous speed variation through inverter (830-2.600 rpm/).
Transmission between motor and gear by means of toothed belt and pulleys;
The high precision ball screw driven on linear bearings and the SIEMENS brushless motor grant the absolute precision in the movement of the cutting head;
Mist spray lubrication of the cutting head and quick blade change;
High-speed and high-precision feeding carriage with 1.200mm-feed and multi feed facilities. Suspended travel on recirculating ball profiled linear guides. Movement by ball screw Ø 40mm, step 40mm, driven by SIEMENS Brushless motor.
Feeding speed increased until max. 100m/; automatic regulation of the feeding speed according to the weight of the piece and of the piece length;
As alternative, high-speed and high-precision feeding carriage with 500mm-feed and multi feed facilities. Movement by ball screw Ø 25mm, step 25mm, driven by SIEMENS Brushless motor;
Integrated lifting system of the whole feeding group (only with 1.200mm travel; option for the 500mm) during the forward motion, in order to avoid frictions and consequent damages on the tube;
Roller plane with bearings, in order to allow the perfect roller rotation also for light tubes.
Hydraulic closing main vice;
Hydraulic closing feeding vice (carriage);
Easy access to the hydraulic valves to adjust the vices clamping force and for general maintenance.
The machine is managed with a PLC Siemens 1500 TIA.
ASEM 10 control panel: a graphic, colour, operator friendly control allows quick and simple changeovers with the machine controlling all production related parameters such as cutting and feeding speeds. The operator just needs to write on the panel the diameter, cut length and quantity or recall a regular job from the extensive memory facility and the machine is ready to work.
2,2 kW oil hydraulic gearbox with variable capacity pump;
Automatic part selector (good part / trim cut / final scrap);
Safety covers according to current laws.
