‘C’ Frame, Open Back, Geared, Fixed /Adjustable stroke, 4-Gib Guided Box type slide, left to right Crank Shaft, Steel Plate, Fabricated Power Press with Automatic Lubrication Device, Motorized Slide adjustment along with Hydraulic Overload Safety device.

  • Frame
    All Frames are steel fabricated frames made from rolled steel plates of IS2062 Gr-‘B’. The main frame plates are in one piece re-enforced by ribbing wherever necessary to provide rigidity to the frame and assuring least defection on full load. The frames are stress relieved before machining.
  • Slide
    The slide is steel plate fabricated/casted box type slide. This accurately machined steel fabricated box type slide runs in extra long gibs fitted with PB liners, eliminating any possibility of tilting and maintains the parallelism of face even at off center loading.
  • Crank Shaft
    The Crank shaft would be of forged and normalized medium carbon steel to ensure toughness and shock resistance. It would be accurately machined and ground finished and so designed to ensure optimum factor of safety.
  • Hydraulic Overload Protection
    The machine is equipped with a standard pneumatically operated hydraulic overload safety device. At the time of overload, by exceeding the rating capacity tonnage, the sensitive Hydraulic Overload Protection device senses the overload with a millisecond and immediately stops the machine. This prevents any damage to the tool and to the press. The machine is made operational by pushing the reset button.
  • Motorised Slide Adjustment
    All ‘ESR’ machine comes with a standard motorized slide adjustment mechanism and is fitted with a brake motor. Brake motor drives the worn shaft and wheel made of P.B. material providing accurate positioning and quick adjustments.
  • Clutch & Brake
    All presses are provided with a combination pneumatic friction clutch & brake unit. The clutch is engaged through air pressure. Brake is automatically applied when the clutch is released. The machine would have provisions for selection of OFF / INCH / CONTINUOUS operation. Emergency stopwatch would be provided in the control panel.
