Moving magnet type (MM type) cartridge
This model uses a boron cantilever and a solid elliptical needle, and is characterised by its delicacy in the high frequencies and good sound balance up to the low frequencies.
Technological capabilities of Nagaoka
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.In response to the evolution of equipment, the needs have been improved every year, initially promoting technology development based on experience. We constantly strive to respond to customers' demands in various ways and finely.
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.
Processing of "hard, brittle" material
Advantages of working with the highest degree of diamonds on earth
Diamond · sapphire · ruby etc. Starting with jewels, cemented carbide, various ceramics .... Although these hard hard materials are superior in abrasion resistance, they have a property that they are brittle and easily chipped, and advanced processing techniques are required for processing. Thirty years after working on micro-processing of the hardest diamond on the earth, Nagaoka applied multidisciplinary technology that is proud of the world. We are steadily responding to requests that are highly accurate and high quality with the times, from 1 / 100th of a millimeter to 1 / 1000th of a millimeter, and even finer.
Multi-product small volume production
Experience is the source of production
Flexible compatibility with in-house manufacturing machinesNagaoka's high level of technical capability has also been utilized for special parts such as styluses (terminals for precision measuring instruments). In general cases where orders of 1 to 2 orders are ordered, these parts are to be produced after receiving design drawings from all customers. The engineering department manufactures machining machines in-house according to need, and accurately responds to minute changes in the shape of the tip of the needle. The accumulated experience, the refined technology, and the flexible organizational structure are in harmony, and we have established our own multi-product small-volume production system.
Delivery first principle
Maximize customer's position, full operation towards the shortest possible delivery date
As a factor that gains trust, let's also say "fast delivery". Since founding Nagaoka boasts that there has never been any trouble with customers concerning the delivery date. For example, there may not be a single needle at a factory, so the whole thing may not move. First of all, rather than profitability and settlement, our company gives top priority to the position of customers that we need. As a special processing expert, we fully utilize full lineup of diamond special tools and in-house machinery, and always follow the shortest delivery term first principle.
Talent
Veteran and mid-sized, young powers gathered, and furthermore hard-working
What supports the reputation of Nagaoka that can be heard in the world, it is nothing but a "human resources capability". Veteran who got special skills and mid-sized, this is a gathering of the power of young employees who back up this and carry on to the next generation. Skilled workers who acquired long experience and skills are the center of human resources. For example, diamond crystals have invisible directionality, and if it is misplaced, it can not be polished at all. They feel with hand vibration and sound, grab and gain polish. Nagaoka's human resources that these professionals are born and raised are just unknown numbers.
Analog technology to support digital
As a key player of analog technology indispensable for the future
The era is high-tech & digital mainstream. However, analog technology is indispensable in any advanced industry, for example, as parts of the space shuttle are also made by the hands of one artisan. Without changing the viewpoint, without digitization to the future, there will be no extension unless there is more sophisticated and specialized professional analog technology. Nagaoka is committed to analog technology where human resources live for the future and will support advanced industrial society.
