In a conventional Friction Screw Press, energy is transmitted from the transmission wheels to the flywheel by friction through a leather band. On the return stroke, energy stored in the moving parts is dissipated as heat by applying brake. In our machines, the two transmission wheels on the conventional Friction Screw Press are dispensed with. The flywheel is driven by an AC servo/ spindle motor through a timer belt/ gear. The motor can be made to run the flywheel at a preset speed very precisely till the dies come very close. The motor is now disabled and the entire energy in the moving masses gets transferred to the job. When the moving die comes to rest, the motor is reversed and the ram returns to its home position very precisely. Since there is no mechanical braking, no energy is wasted during return stroke. The motor brakes on line – regeneration principle where the kinetic energy in the moving mass is converted to electrical energy and sent back to the mains. Since the drive motor does not run when the ram is stationary no energy is consumed during idling of press

We offer linear friction welding technology. The machine shown has 10 tonne capacity and can weld cross sectional area of 1000 sqmm. In medium carbon steel. Oscillation is imparted mechanically through a crank driven by spindle motor and drive.

Linear Friction Welding is a solid-state welding process in which heat is generated by friction due to the lateral motion of one of the parts to be joined. Once the surfaces get hot enough to become plastic, a forge force is applied to join them together. This is widely in Aerospace for manufacturing integrated bladed disks (blisks) for aero-engines. Linear Friction welding is seeing increasing adoption in other areas too, like Automobile, Medical Shipbuilding etc.

We are offering friction welding machine. Eta offers friction welding machines in various configurations specially tooled for specific applications. For jobs like axle housings and propeller shafts, double head machines are available. Choice of automatic material handling, flash removal by turning, milling or shearing.

We offer friction surfacing machines. Machines can be built to cater to various axial loads and job sizes. Machines can be supplied in single or double column configuration. To maintain tool angle in linear welding the head can be tilted manually. For contour welding the tool can be tilted automatically to follow the required path. Rotary table can be incorporated for pipe welding.

We are offering electrical upsetting machines. A high density of electric current at very low voltage is made to pass through a portion of the end of the bar stock, which is held against an anvil and clamped between two jaws, to generate sufficient heat to make the portion red hot and plastic. An upsetting force is applied axially on the rod against the anvil making the portion, which is in plastic stage to deform into a bulb shape and to gather the required volume. This process is usually followed with a forging operation to get the required shape. Eta supplies production cell with single or twin upsetters and a servo forging press integrated with work handling system for automated production of ic engine valve forgings.

We offer electrical dc upsetting machines. • heating transformer works on 3 phase 400vac. • dc heating. • no skin effect as in ac heating, thereby providing uniform heating across the cross section of the job. • heating power infinitely variable by thyristor. • auto indexing of anvil after every upsetting cycle. • bulb temperature measured by optical infrared pyrometer and controlled by hydraulic servo valve. • bulb shape is controlled without wrinkles by anvil speed control using another servo valve. • maximum upsetting force – 7000kgf.

We offer deflash machines for engine valves. The weld flash on the friction welded job is turned off in this machine by either single point turning or by plunge cut. Subsequently the job while in rotation, is bent by a set of rollers in all the planes by a definite angle and then straightened automatically. This ensures the quality of the weld joint. The cycle time of this machine matches with that of the friction welding machine so a single operator can handle both machines.

This machine is used for slot cutting of commutator risers. The job is rotated for one turn and the angular position of every copper segment is recorded by means of a laser sensor. Now the job is precisely positioned such that the slotting cutter can cut the first slot in the middle of the segment. After every slot the job is indexed by the precise angular displacement and all slots are cut. Jobs are loaded and unloaded automatically. Average cycle time (floor to floor) for a 23 segment commutator is 16 seconds. In twin head machines up to 6 slots can be cut in a second.
