EDM machining the smart Solution for machining Hardened Materials
EDM machining the smart Solution for machining of hardened Materials
Higher levels of Quality combined with outstanding service is key to
succeeding in the manufacturing engineering industries in Australia
The team at ALNO Product Services offers a complete EDM Machining service, EDM - Electronic Discharge Machining opens
doors to a range of machining solutions across industries. EDM machining allows metals to be cut with high accuracy, especially those
with extreme hardness and complicated geometry, or those components
where general machine tools make it impossible to machine using traditional methods.
EDM provides a single and
accurate solution for very small components that are usually difficult
to machine in general practices/machines. Die sinking reproduces, in a metallic workpiece, the shape of a tool
called electrode. Injection molds for plastic parts are very frequently
machined by die sinking.
The shape given to the electrode is that of the object that is going to be molded. In the machining area, each discharge creates a crater in the workpiece - material removal and an impact on the tool - wear of the tool/electrode.
There is never any mechanical contact between the electrode and workpiece. The team at Alno Product Services manufacture electrodes from copper or graphite.

EDM Machining Process
The team at ALNO Product Services offer a EDM Machining process for Complex Geometric Forms.
The EDM Machining Process has a number of benifits which include
The EDM Machining Process has a number of benifits which include
- Complex contoured shapes can be produced in one piece rather than several, in the exact configuration that is specified.
- The EDM process offers a Rapid, Economic Production of Prototypes and Low Run production Parts
- Offers additional capabilities to accurately machine complex designs, can eliminate or
reduce fixture and tooling costs for precision production
parts.
- Precise Machining of Pre-hardened Materials
- Hardened materials can be EDM eroded, the need for the heat
treatment of machined parts is eliminated, avoiding potential
distortion.
- Machining to Tight Tolerances, Avoiding Distortion and Stress
- Very low machining forces allow tight tolerances of up to 2 microns
to be achieved. With little or no stress imparted into the work only
light clamping is necessary. Thin materials can also be machined without
distortion.
- The Accurate and Economic Machining of Exotic Materials
- Exotic materials including A-286 Superalloys, medical grade
stainless, titanium, Hastelloy, tungsten carbide, molybdenum, aluminium
alloys and copper can all be machined. Better utilisation of valuable
materials is provided through chipless machining.
- Absolute Consistency Between Machined Parts.
- Because with wire EDM there is no contact between the cutting wire and the surface, there is no tooling wear and absolute consistency can be achieved on every machined part.
EDM Machining is just one service amounst many that the team at Alno Product Services offer other services include:
- Precision Engineering
- Wire EDM, Sink EDM
- Press Tools
- CNC Milling & Turning

Electric Discharge Machines (EDM)
EDM
can be used to machine conductive materials of any hardness with the
exception of steel or titanium to an accuracy of up to one-thousandth
of a millimeter with no mechanical action. By virtue of these
properties, EDM is one of the key technologies in mold and tool making.

EDM - Injection Mould - Sink Marks
Sink marks are a common potential pitfall of designing for the
process of injection molding in many cases without the correct design tools sink marks are unavoidable.
Melting plastic pellets and molding them into a part seems like a rather simple endeavor although, sometimes can be anything but. A sink mark is a local surface depression or void that typically occurs in moldings with thicker sections. They are also common in locations above ribs, bosses, or internal fillets. As the plastic cools at different rates in the mold, the surface hardens but leaves the thicker areas in the center still molten. As the thicker areas cool, they contract and leave depressions in the surface of the part; sometimes the part may even warp completely
Sink marks can be avoided by:

As the thicker areas cool, they contract and leave depressions in the surface of the part; sometimes the part may even warp completely
Sink marks can be avoided by:
- Core out the solid sections of your part to reduce thick areas.
- As a rule of thumb, make sure that all bosses and locating & support ribs are no more than 60% of the thickness of your nominal wall.
- Modeling your part in Soildworks through the design process.
If you have any questions with regard to the injection moulding process and creating injection mould through the EDM machining Process please feel free to contact ALNO product Services for more information.

EDM the Process
EDM is a high precision metal removal process that uses thermal
energy from a fine, accurately controlled electrical discharge -spark
to erode - vaporize metals.
The scope of the EDM process ranges from the
drilling of micro-holes that are smaller than a human hair to machining
100,000 pound automotive dies. In EDM, the workpiece must be
electrically conductive and the machining gap submerged in a dielectric
fluid. In the EDM sinking process, the inverted image of the tool
electrode is gradually impressed in the workpiece.
Although each
machine type is significantly different in design and application, they
all use thermal energy produced by pulsed spark discharges for metal
removal. The two primary types of EDM systems are "Die-Sinking" and
"Wire" EDM. Die-Sinking machines are also called Sinker, Ram-Type,
Conventional, Plunge or Vertical EDM.

EDM Production
EDM Production
The EDM (Electronic Discharge Machine) process is most widely used to produce prototypes, components tools, product parts, dies and molds. Across a range of industries such as aerospace, automobile, manufacturing and electronics particularity where production quantities are relatively low. Through Sinker EDM, a graphite, copper tungsten or pure copper electrode is machined into the desired (negative) shape and fed into the workpiece on the end of a vertical ram.For more information on EDM Production contact ALNO Product Services
EDM - Sinker
EDM - Sinker or EDM - Cavity, in general terms it consists of an
electrode and workpiece that are submerged in an insulating liquid or dielectric fluids. The electrode and
workpiece are connected to a suitable power supply. The power supply
generates an electrical potential between the two parts. As the
electrode approaches the workpiece, dielectric breakdown occurs in the
fluid, forming a plasma channel, and a small spark jumps.
These sparks usually strike one at a time because it is very unlikely that different locations in the inter-electrode space have the identical local electrical characteristics which would enable a spark to occur simultaneously in all such locations. These sparks happen in huge numbers at seemingly random locations between the electrode and the workpiece. As the base metal is eroded, and the spark gap subsequently increased, the electrode is lowered automatically by the machine so that the process can continue uninterrupted. Several hundred thousand sparks occur per second, with the actual duty cycle carefully controlled by the setup parameters. These controlling cycles are sometimes known as "on time" and "off time", which are more formally defined in the literature.
The on time setting determines the length or duration of the spark. Hence, a longer on time produces a deeper cavity for that spark and all subsequent sparks for that cycle, creating a rougher finish on the workpiece. The reverse is true for a shorter on time. Off time is the period of time that one spark is replaced by another. A longer off time, for example, allows the flushing of dielectric fluid through a nozzle to clean out the eroded debris, thereby avoiding a short circuit. These settings can be maintained in micro seconds. The part geometry is a complex 3D shape, often with small or odd shaped angles. Vertical, orbital, vectorial, directional, helical, conical, rotational, spin and indexing machining cycles are also used.
