  • Solid design of the machine base.  The meehanite cast iron components and high-grade guides are an assurance of durability and long-term accuracy.
  • Good accessibility permits convenient and swift set-up. The tidy work area is designed and optimized for easy workpiece clamping. Furthermore, the work table from granite makes the machine compact and permits loading with heavier workpieces.
  • 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 150:1. 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.
  • This makes set up and operation more user friendly and keeps work free of oils or other contaminates. The user-friendly control allows simple input of cutting variables. Included is an audible edge find, voltmeter to monitor stableness of burn and Programmable Digital Readout for ease of positioning. A standard feature is a Power Back Slide (300mm W Axis) for additional travel to accommodate increased part thickness.
  • Novidrill 400/500-II not only manages small dimensions on start holes with 0,2– 3,0 mm electrodes, but also functional bores. It offers comfortable operation during manual positioning, while the NC can calculate automatic many hole coordinates.

Granite Table : SOO MUCH BETTER !!!

Granite Table Standard

Big advantages:

 

Can not drill in the table

Table resist to corrosion of the dielectricum (drilling liquid)

Don't get rusty

Keeps the super precision in time and guarantees a better flatness

Parts can not be welded to the table due to electrical current through the contact surface with table

High speed drilling with reduced bullet nosing

  • Novidrill 400/500-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 150:1. 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.

Most economical high speed drilling machines

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.
