Examples of machining medical parts

Machining Samples

FP power supply, FP-V power supply

• The FP power supply equipped in the EA/VA/MA Series, and the

FP-V power supply equipped in the EA-V Advance Series can

be used for machining molds, and for electrical-discharge

machining in various applications and fields

•

Extremely hard materials, which are difficult to mill or grind, as well

as special materials and ultrafine areas can also be machined

Full of useful options

• The EDM is used in a variety of applications and fields 

Optimum machining can be realized with various special

specifications such as the indexing unit (A, B and C axes),

spindle unit, special working tank and column up (Options may

be limited according to the model. Refer to the product

information section for details)

Example of fine-hole machining

Examples of tungsten carbide fine-surface machining

NS powder

NS powder specifications

• The NS powder added to the dielectric fluid is dispersed by stirring the fluid in the working tank and dielectric fluid reservoir,

thus improving machining stability

• Effective for finish machining of large electrode areas

Realizing high-grade finished surfaces

Highly efficient finishing with large electrode areas

* Affected by workpiece's heat treatment.

Special stirring equipped unit.

When finishing with NS powder, a uniform and high-grade

finished surface can be attained compared to surfaces machined

with normal dielectric fluid.

Pinholes and stains, are suppressed, and the time required for

the mold finishing process is greatly reduced.

An easy-to-polish matte surface finish, and polish-less glossy

surface finish can be realized.

High-speed, High-grade Finish

Powder ability based on material

Non-glossy Glossy*

• An uniform matte surface and polish-

less glossy surface can be machined

simply by adding NS powder to the

dielectric fluid

• Pinholes, stains and surface flatness

are suppressed

Contours can be machined using a rod-

shaped electrode based on data drafted

with the CAD. A glossy surface can be

machined even without using the NS

powder specifications.

Workpiece material HAP40

Electrode material Copper

Using the NP2 circuit, machining of Rz: 1μm

(≒ Ra: 0.15μm) or less is possible even in

tungsten carbide machining. This is especially

useful when machining complicated patterns

where orbiting is not possible.

Electrode material Copper tungsten

Titanium and cobalt alloys used in medical

parts can also be machined with electrical-

discharge machining. The high-performance of

EDMs with the FP-V power supply is also

suitable for machining various special

materials used in aircraft.

Fine holes approx. φ0.2 to 1.0mm 

in size can be machined with the

Fine-hole jig option. This function

can also be used as a start hole

for wire EDM processing.
