Hole drilling EDM

Our Novidrill EDM Rapid hole drilling machines use low cost electrode tube (normally brass or copper material) to drill holes on a electrically conductive material at a very high speed, the hole depth diameter ratio can reach up to 300. The hole diameter is normally from 0.3mm to 3.0mm, the machine can drill holes on a inclined surface workpiece. This technology is widely used for hole machinig in aerospace, energy, cutting tools, automotive, medical, mold and die industries.

High-speed EDM hole drilling was designed especially for fast, accurate small- and deep-hole drilling applications. Small holes that were once almost impossible to drill by conventional machine tools are now being performed with ease. With the capability of drilling through virtually any conductive material, the use of this technology is continually expanding.

Considered a last resort for drilling holes, Fast Hole EDM Drilling (Electrical Discharge Machining) is quickly becoming the standard method for producing small, tight tolerance holes. It is an extremely cost effective method for producing fast and accurate holes into all sorts of whether hard or soft conductive materials. 

CAN USE NORMAL TAP-WATER

More economical is not possible.

Designed to meet the needs of any job shop and the most demanding Toolmaking workshop, the Novidrill PRO-plus is simply the most unique EDM Drill on the market today. This feature packed machine combines affordability, precision and versatility with a host of standard features.

Compare the features with others and we are sure you’ll agree: The Novidrill PRO-plus offers more than competitive machines that sell for twice the price!

Novidrill‘s ability to use ordinary tap water as dielectric, coupled with a unique super high pressure pump system which provides excellent flush and stability at the electrode during the burn.

An EDM drilling system simply must get the job done – and must not distract from important tasks. The Novidrill PRO+ is therefore designed to bring the user quickly and simply to his goal. Speed and simplicity are also all-important as far as maintenance and organization are concerned – everything is readily accessible and accommodated immediately in the machine.

The perfect complement to the wire-cutting machines. The start-EDM drilling systems not only master small dimensions on start holes with 0,3–3,0 mm electrodes, but also functional bores.

High Speed drilling with reduced bullet nosing

High pressure pump 120 Bar max

  • Novidrill-II uses a unique pneumatic activated high pressure (70 – 120 bar) coolant/dielectric/water pump. The combination of the super high-pressure dielectric fluid, the rotation of the tubular electrode and the high electrode feed rate (controlled by a fast response servo) make it possible to produce holes at a very fast rate and of very small dimensions (till 0,2mm diameter)
  • High pressure dielectric fluid is one of the most important factors, which is usually supplied to the gap through the bore of tubular electrodes.
  • The use of our pneumatic intensifier pump results in drilling parts up to 50% faster and with lower operating costs as much as 40%! Our high-pressure pump produces 30% more pressure than a standard water jet pressure pump, resulting in a 40-50% increase in productivity for many materials. Compared to a water jet pump, typical operating pressures uses 30% less water, 30% less power, and up to 50% less electrode consumption, resulting in a 40% reduction in operating costs. Being green with energy does not only spare the nature but also your wallet.
  • Auxiliary Flush provides continuous cleaning of die guide and work piece and aids electrode entry and breakthrough.
  • peed and simplicity
  • Drilling rates up to 1mm/second can be achieved and obtainable hole sizes are between 0.2 and 3mm, with a length-to-diameter ratio of over 300:1. The process can be applied in the production of a variety of parts including fuel injectors, cutting tools, medical equipment, start holes for wire cut and more.
  • Factors including the generator (electrical parameters), electrode geometry and most important, the dielectric flushing are very important for the correct EDM process. Drilling time and electrode wear can be reduced by 85 % and 45% respectively, depending on the type of electrode geometry used and pressure of coolant applied.

Today’s most economical solution for producing high precision and high-speed holes.

Electrical Discharge Hole Drilling (EDHD) - EDM-drilling

Considered a last resort for drilling holes, Fast Hole Electrical Discharge Machining (EDM) Drilling is quickly becoming the standard method for producing small, tight tolerance holes. It is an extremely cost-effective method for producing fast and accurate holes into all sorts of whether hard or soft conductive materials. EDM drilling operates on the principal of eroding material via the use of electric energy.

There are many advantages of using fast EDM drilling versus conventional drilling:

  • Some materials are too hard to drill using conventional methods. The EDM machine drills through almost any conductive material including carbide and hardened steel.
  • Drills tend to bend in contact with the surfaces. To prevent this, additional fixtures and guide bushings must be used.  With EDM drilling, the electrode never contacts the material being cut, thus eliminating the tool pressure normally experienced when drilling on curved or angled surfaces.
  • Deburring holes drilled by conventional methods can take longer than the drilling. EDM drilling creates no burrs. This burr-free drilling saves time and labor and is especially crucial when difficult holes are being drilled. In addition, surface finishes are better. The smaller the hole, the more important a smooth surface is.
  • Drilling holes with conventional methods is often extremely difficult if not impossible. EDM drilling is often the only practical method for producing such holes.
  • As conventional drills enter or exit, they can break if torque is not carefully controlled.  Small broken drills are often difficult to remove from the work piece, and time is wasted replacing broken drills and parts may have to be scrapped. With EDM drilling, torque conditions do not exist since the electrode never contacts the workpiece.

If required close tolerance, small holes EDM drilling is "the" technology to utilize. By reducing the discharge energy, holes can be polished.

This machine can be used not only to drill precise holes in medical and dental instruments, but its applications has such a wide variety and even includes drilling holes in rocket turbine blades, fuel injectors, cutting tool coolant holes, hardened punch ejector holes, plastic mold ventholes, and starter holes for wire EDM.

Drilling times samples

Drilling times depend on the hole size and type of material. A few examples.

Material Electrode Dia. Drill Depth Machining Time
Alloy Tool Steel 0,5mm 12,5mm 25 ~ 35 seconds
0,5mm 25mm 50 ~ 60 seconds
1,0mm 25mm 55 ~ 65 seconds
Tungsten Carbide 0,5mm 12,5mm 4 ~ 5 minutes
0,5mm 25mm 8 ~ 9 minutes
Aluminum 0,5mm 12,5mm 40 ~ 50 seconds
0,5mm 25mm 90 ~ 100 seconds
1mm 70mm 3 minutes

High Precision drilling guides

Easy changing of drilling diameterdiameter

The new developed High Performance generator of the Novidrill allows machining of all steel and Tungsten Carbide materials.

The Electrode wear is virtually all on the bottom of the electrode (not on the side like on machines with conventional generator), which avoids conic wear. As a result, the breach has a perfect shape and will be reached much faster!

The use of our pneumatic intensifier pump results in drilling parts up to 50% faster and with lower operating costs as much as 40%!

Our high-pressure pump produces 30% more pressure than a standard water jet pressure pump, resulting in a 40-50% increase in productivity for many materials.

Compared to a water jet pump, typical operating pressures uses 30% less water, 30% less power, and up to 50% less electrode consumption, resulting in a 40% reduction in operating costs.

Our digital generator keeps the consumption of enrgy under control and not using special oils or dielectrcal fluids keep the enviroment clean.

Being green with energy and enviroment does not only spare the nature but also your wallet.
