In modern times where high-tech conversion advances, various machines are moving in every scene including OA equipment. You can not miss having an active part of expendable parts that needs "wear resistance" there. "Diamond record needle" Nagaoka "makes various consumable parts, making full use of the world-recognized technology. Specialty machining such as joining and polishing of hard hard-to-cut materials indispensable for general-purpose machinery and general technology is specialized field, and we have won a lot of trust in its advanced technical strength.
Main processing technology
The precision processing technology of diamond that Nagaoka accumulated blossomed to not only the record needle but also hard-to-cut materials such as cemented carbide and magnet parts, ultra fine processing.
Keep moving, keeping memories memorable, telling the splendor of music to the next generation.
A person listening to the record says Nagaoka as "a record needle ..." We take pride in this fact and believe there is a responsibility that has continued to produce record needles for more than half a century.
Nagaoka is the only manufacturer that can consistently produce products ranging from the sound groove of the record to the amplifier.
We perform all inspections in every work of drawing from plate material, molding of aluminum pipe, welding diamond needle, polishing work one by one and handmade one by one.
The assembled finished product continues to provide products of stable quality by inspecting characteristics using an inspection machine such as an oscilloscope.
Replacement needle for cartridge maker
Manufacturers have already produced and supplied replacement needles for products whose production has been completed.
Original MP cartridge
In addition to supplying record needles, we are manufacturing moving permalloy type cartridges that can exchange needles developed by Nagaoka.
Diamond and various metals are bonded in a vacuum welding furnace, then the diamond is polished into a cone or a square pyramid.
This processing technology is also applied to styluses (precision measurement equipment terminals) and special tools for diamonds.
Particularly in welding, we are proud of bonding technology capable of weighting about 500 grams with 0.1 mm 2 joining surface.
In addition to this, precision polishing and microfabrication of gems such as sapphire and ruby are also carried out.
Precision measuring equipment terminal
The high-level technical strength that Nagaoka has cultivated is also used for special parts such as terminals for measuring shape and surface roughness.
Diamond special tool
The polishing of diamonds is performed precisely and delicately by skilled workers.
Precision grinding and microfabrication of precious stones such as sapphire ruby
Diamond precision processing technology accumulated by Nagaoka is utilized for difficult-to-cut materials such as sapphire, rubies and other jewelry, ultra-fine processing.
Compared to diamonds, wear resistance is somewhat inferior, but it is hard to be chipped, cheap and economical also attracts attention is cemented carbide.
In the precision machining of cemented carbide materials, we produce replacement blades for cutting plotters that are interlocked with computers.
This product machines the tip of a cemented carbide into a knife shape, and the cutting edge part is a fine work with a microscope.
The jewelry polishing technique is also made use of greatly here, boasting world-class quality and the industry's largest share.
We also offer terminals for various precision measuring instruments using cemented carbide materials.
Precision measuring equipment terminal
We have hundreds kinds of production experience according to various measuring objects. We will manufacture from 1 order.
In the precision machining of cemented carbide materials, we produce replacement blades for cutting plotters that are interlocked with computers. This product is made by processing the tip of a cemented carbide into a knife shape, born from a fine polishing work using a microscope. The jewelry polishing technique is also made much use here.
Processing of magnets indispensable as motor parts is a field where demand grows year by year.
In Nagaoka, the technology of special shape processing, precision processing, micro / fine processing is reflected in the product according to the customer's order.
Magnet parts produced by our company are also active in mobile communication equipment, computers, automobiles, cameras, various household appliances, and other places close to their lives.
We mainly deal with samarium-cobalt and neodymium-iron based parts of rare earth magnets.
Production method by original processing machine
Magnet processing essential as a motor part. In Nagaoka, the technology of special shape processing, precision processing, micro / fine processing is reflected in the product according to the customer's order. Magnet parts produced by Nagaoka are playing an active part in living situations such as mobile communication equipment, computers, and cars.
Special processing of various kinds of ceramics is also expected in the future where demand growth is expected.
In Nagaoka, we manufacture machining machines in-house according to orders where specialized technical staff diversify each time.
Such an integrated system enables the production of many kinds of parts with higher precision and lower cost and short delivery time.
Probe pins used for LSI inspection are machined into a conical shape that is thinner towards the tip because of high density mounting on inspection equipment. Compared with traditional electropolishing process, it is possible to process pins with excellent taper angle and linearity.
Special processing of various ceramics is also a field where demand grows in the future. In Nagaoka, we design and manufacture special machining machines in-house according to orders that specialized technical staff diversify. Such an integrated system enables the production of more sophisticated components in a variety of products, as well as lower costs and shorter delivery times.
