• ETA offers high speed production cell with auto loading of Upsetters unloading transfer to Press and unloading from Press
• This is a combination of two Twin Head Uptsetters and a Positive Drive Screw Press with a Component Handling Robo which is capable of producing a Valve forging every 5 seconds

The cell is designed for continuous production of engine valve head forgings. This consists of a Servo controlled Screw Press and two double head Upsetters and a Robot. The Upsetters are placed on either sides of the press, while the Robot is placed in between the Upsetters and in front of the Press. Individual Automatic component loading mechanism are provided on the Upsetters The bar components loaded manually into the bins of the Upsetters are picked and placed into the clamping vices of Upsetters. On Upsetting operation, the job is picked by the Robot and it places into the bottom die in the Press. The ram of the Press gets actuated to do forging operation, after which the unloader mechanism in the press take away the forged piece and puts in to a collection bin. All the machines are so precisely synchronized and programmed for continuous production run for making valve head forgings. The machine has a PLC based control system.

This apparatus enables to test Geological rock samples for stress/strain characteristics under compression, tension and torsion, subjecting pressure up to 5000 bar and temperature up to 1300oC.

It consists of a Torsion actuator, Pressure vessel, Furnace, Multi range load cell, Bubbler, Intensifier, Pore fluid Volumometer and an Axial actuator and is designed to simulate the conditions of earths inner core.
The test specimen can be subjected to an extreme torsional displacement from 5x10-8radians / second to 5x10-3radians / second. The internal electrically heated furnace produces the extreme temperature condition. A hydraulically driven intensifier builds up and holds the confining pressure.The specimen can be subjected to an axial loading of 100kN, with displacement rating from 0.005 m/ second to 500m/second. A specially designed multi range load cell with LVDTs helps in measuring axial displacement, torsional load, and axial load on the specimen.

Pore fluid volumometer enables for a deeper study regarding the effect of pores in the rock samples. The bubbler unit provided helps in detecting any leakage of inert gas from test chamber.

The apparatus has a central Mitsubishi PLC based control system with servo motors for applying and controlling different types of forces. A Eurothem module is used to control temperature. ETAs own developed software interface makes the machine more user friendly.

This machine is designed for duplex milling of Aluminium housings with component loading and unloading done manually. The machine has twin spindle assemblies and they are mounted on individual spindle housings, which move in opposing directions on LM guide ways fitted on the machine frame. The spindle slides are driven by servo motors through set of ball screw and timer pulleys. The spindles are run by induction motors through inline couplings. The aluminium component is carried in a fixture mounted on a central slide unit. The fixture slide is fed in between the cutters for milling operation on both the faces of the component simultaneously. The parallelity achieved is less than 8 microns

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.

• Available in 140-250 Tons
• Flywheel Driven

This press is used for making forged parts like Engine valve head. It consists of a vertical rectangular frame on top of which a servo controlled motor is mounted, which drives a Screw mounted with a fly wheel to move the ram of the press up and down. The ram bottom is fitted with top die, while the bottom die is mounted on the bolster plate of the press. The servo motor is 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 moving mass gets transferred to the job kept in the bottom die. When the moving die comes to rest, the motor is reversed and the ram returns to its home position. Since there is no mechanical braking, no energy is wasted during return stroke. The motor brakes by online-generation principle, where the kinetic energy in the moving mass is converted to electrical energy and sends back to the mains. Since the drive motor does not run when the ram is stationary, no energy is consumed during idling of Press.

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.

This is an intelligent machine, which automatically calculates the extent of bend and its location on a shaft and straightens it by using a built-in hydraulic press. This fully computerized machine is available for straightening of shafts with various diameter and lengths.
