EDS 200, EDS 400, EDS 600 & EDS 1000
After extensive R & D for the past 30 years in the field of Electric Discharge Machining, now Electronica is introducing High-Speed Sawing Machines using the Electric Discharge principle for cutting all metals, including exotic ones.
Ideal for Aeronautical Engineering, Metallurgical and Research laboratories, Defence workshops.
How it works
An endless Mild Steel belt is used as an electrode to cut the workpiece. This Mild Steel belt rotates continuously over the two pulleys under tension. The thickness of this Mild Steel belt ranges between 0.5 and 0.9 mm and has the width between 19 and 40 mm and the length approximately 7500 mm.This electrode is fed to the workpiece with the help of Servo system. Water-based diluted Silicic acid soda (Sodium Silicate) solution or distilled water is used as dielectric.
Performance
Maximum cutting speed : 10 to 30 cm The cutting speed is calculated considering the cross section the workpiece that is to be cut. For example, to cut a slice out of square bar of 10 cm x 10 cm it will require roughly 10
Depth of the heat-affected zone on the sawing surface : < 0.5 mm
Applications
Sawing of hard metals & exotic metals such as Titanium, Stainless Steel, Super Alloy, Inconel, Cast Steel etc.
Sawing of fragile or soft materials, honeycomb, thin pipes etc.
Works on all types of metals used in Aeronautical Engineering
Most suitable for sawing materials such as, Tool Steel, Super Heat-resistant Alloy, Stainless Steel, Cast Iron and Cast Steel
Advantages
It can cut any electrically conductive material irrespective of its hardness.
Sawing of spherical or slanting surface.
Faster than band saw in case of hard materials.
Minimum loss of material, as the cutting width is less than 1.5 mm.
No deformation of the workpiece.
Good sawing efficiency irrespective of the hardness and resistance strength.
Only a small zone gets affected due to heat generation.
Easy clamping due to very small sawing resistance which is 300 to 500 gm per sawing width of 10 mm.
Very low running expenses.
Operational Features
Automatic belt tension adjusting system with a sensor in case of belt elongation. It is interlocked with the process to ensure cutting with higher efficiency.
Pneumatic job-clamping system (optional) This clamping system is separate from the worktable. Hence, a continuous cutting and feeding is ensured without loss of time in clamping the workpiece.
Motorised trolley / roller conveyor (optional) for continuous feeding of the workpiece for cutting
Motorised Y axis movement (optional) with position feedback, allows precise positioning of the workpiece Y axis movement is disabled during the cutting operation, ensuring trouble-free cutting
Separate strip butt welding system with built-in grinder, allows instant welding of electrodes
Water cycle exclusively for aluminium cutting
Safety Features
Enclosed work area with interlocked doors ensures higher operator safety
Enclosed belt wheels with interlocked covers to ensure safe replacement of the belt
Built-in fume extractor with coolant separating facility for fume-free work environment, without loss of the coolant
Easy maintenance
Separate automatic wash cycle for cleaning the work area automatically with a single-key operation
Easily replaceable ceramic guides and carbon brushes allow easy maintenance
