Product Description

Product Description

Machine Base

The machine base is manufactured of one piece close grained graded cast iron.  Box type design, heavily reinforced with ribs, provides high rigidity and stability.

 

Machine Guideways

  • V & Flat guide ways precisely hand scrapped for Cross (X-Axis) & Table slides (Z-Axis) with turcite coating which gives stick slip free movement
  • Excellent vibrations damping and high positioning accuracy, which insures better lubrications and longer life of guide ways.
  • The X-Axis can be equipped with linear measuring system, depending upon requirements (Optional).

 

Work Head

  • Dead Centres as standard, live cum dead centres as optional
  • Easy belt tensioning arrangement.
  • Special arrangements provided in front to avoid entry of coolant inside work head.

 

Wheel Head

  • Cartridge type grinding wheel spindle operating at 33 m/s or  45 m/s cutting speed & with precision anti friction bearings. Constant Cutting Speed of grinding wheel though variable speed drive (Optional)
  • Robust wheel head with anti friction bearings is maintenance free has good thermal stability.

 

Tail Stock

  • Rigid design and facility for adjusting Tail stock quill clearance.
  • Hydraulic actuation (Optional)
  • Micro correction attachment for taper setting  + 0.030 (Optional)

Optional Accesories

Automatic In-Process Guage

IPG automatically and continuously measures the diameter being ground and compares the actual size to preset values. Confirming the diameter to the accurate dimension.

 

Flagging

Detects the end face position on work piece,  reduces idle time and ensure safety.

 

Dynamic Balancing System

Dynamically compensates the imbalance of grinding wheel. Balancing system improve the surface finish and geometry of the work piece.

 

Gap Eliminator / Crash Control

This device will automatically detect the setting up or machining condition occurs, the grinding wheel will rapidly retract for safety.

 

Lineal Scale for X and Z axis

Gives actual slide movement feedback to CNC system up to submicron level

  • Robust design of machine elements with high reliability and easy maintainability.
  • The   ECG  Series is developed for grinding of mass and batch production of medium and heavy size components.  This machine offers a cost effective solution for external cylindrical grinding application with straight or angular wheel head option
