• Natural diamond wire drawing dies

Natural diamonds, abbreviated as ND, are naturally formed within the earth at high-pressure and high-temperature conditions. Because of its extremely rigid lattice, it can be contaminated by a few types of impurities such as boron and nitrogen.

MN Dies strictly control diamond selection, <111> crystal orientation,diamond grinding,mount,laser drilling,lathe case,ultrasonic polishing,wire polishing, geometry inspect

This laser drilling machine is a computer control programmable and can make the hole according to different request of hole profile and reduction angle.The advantage is stable laser beam, less burn and consistent profile.

MN Dies supply semifinished and finished nature diamond dies.

Hole size range

Semifinished:From 0.004mm to 1.600mm,bigger by request.
Finished:From 0.075mm to 1.600mm,bigger by request.

Advantages

Precise die orientation
Accurate die profile
Highly polished finish from bell to back relief
Accurately size
Straight & consistent reduction angle
Maximum wear resistance
Minimum die pull and friction
Excellent wire surface quality

Applications

Used in fine and ultrafine wire sizes, or for drawing wire of critical surface quality.

Features

·  Natural diamond wire drawing dies, abbreviated as ND, are naturally formed within the earth at high-pressure and high-temperature conditions. Because of its extremely rigid lattice, it can be contaminated by a few types of impurities such as boron and nitrogen.

·  ND dies are similar to SSCD and are an excellent option for manufacturing fine and ultra-fine wires. Natural diamond dies provide superior quality, hardness, accuracy and a long service life for each die. They yield precision wire with an excellent surface finish, enabling high drawing performance and low power usage due to low friction.

ND dies are frequently used for drawing

· Tungsten filament wire

· Bonding wire (gold, copper, aluminum)

· Medical wire

· Stainless steel wire

· Copper wire

· EDM wire

· Special alloy and high-performance alloy wire

· Precious metal wire

· Various other ferrous and non-ferrous metal wire types
