FAQ [Nissin Sangyo]

I tried to summarize the words confusing.
We hope you are able to refer to when you purchased the product.

	Term	Meaning
A	Alumina oxide ceramic	This is used in the various forms by sintering those in powder by oxidizing aluminum. It is a material having a thermal expansion is low even at high temperature high hardness. I wrote a AL2O3 chemical formula, hardness will also be used to search material in Morse 9. You colored pink in .0.5% will be in red ruby and 1% the whole country (Chrome) Cr. I will color in green and chrome vanadium is added to the aluminum oxide. This is called Emerald. It is not used for jewelry it is possible to make both industrially. [Break] It is specifications to dental materials in white individuals and sintering (ZrO2) 2 zirconium oxide in the ceramic. Toughness high industrial value greater than alumina. Stabilized zirconia was added 4-15% approximately yttrium, calcium, magnesium, hafnium and zirconia It is used in jewelry has the same refractive index as the diamond is transparent. Popular and cheap as 100 yen less than 1 carat price. It is zirconia repelling oil To try the authenticity, If you give an oily pen. Softer than diamond 8.5 and hardness, are you the judgment of authenticity jeweler examined with a magnifying glass it is you're investigating the corner is not turned round.
B	Black alkali treatment	It is called a black oxide generally. Method for producing a layer of iron oxide black on the surface by immersing the steel parts in the alkaline solution was warmed. Those black shiny such as gun is obtained by this process.
	BT shank	Generic name of the shank to be used in machining centers. Called bottle grip tapered, and is described in JIS6339. In order to grasp the tapered surface of the shank in the Japanese standard, it becomes impossible to take the main shaft is pulled to the rear by the centrifugal force when rotating at high speed, and is employed in machines 10,000 rpm or less. I play an effective role in heavy cutting.
	BBT shank	Shank to constrain the tapered end surface of the BT shank. There is no bite in the high-speed rotation as BT shank, but unsuitable because there is too much inertia in the high-speed rotation.
C	Chattering phenomenon	When the stylus touches the work, voltage and current amount is rapidly changing due to electrical resistance, and a phenomenon to disappear (LED) or with lamp apparently.
	Ceramic bearings	Steel bearing faces in heavy cutting, but can not be used at 10,000 rpm or more so would be burned out when you high-speed rotation. It is used for the higher toughness than aluminum oxide without seizure even at high speed rotation is made of silicon nitride material, is divided by the low-impact.
	Chrome-plated	Plating of iron, which was a chrome treatment after nickel-plated. It is a luxury plating tinged with pale yellow.
E	External contact type	Measuring instrument that can be used to work with a electric conductivity. Point Finder (Waterproof also OK), NS Tool Setter, centering gauge swing type this is the case. If you want to measure the work without electrical conductivity measurement instrument (point finder i, tool setter i) internal contact type.
G	Gold plate	After applying the nickel-plated copper metal, to apply gold plating. I can control the thickness of 0.1μm.
H	HSK shank	Shank standard of machining center of Germany. It is prescribed in DIN69893-1 ~ 6. It is advantageous for high-speed rotation is fixed at the end face and the tapered surface, but is not suitable for heavy cutting.
I	Internal contact type	Instrument which can be used when the measurement object is measured the non-metallic wood, or plastic.
M	Measuring pressure	Load applied when measuring objects. There is a mechanical or internal contact system and (energizing type) external contact system, Energizing formula is sensitive is capable of detecting edge and workpiece at the touch. Detection function is provided in the sensor main body, the internal contact system can be detected as it not energized. 0.3N position is often the measuring pressure. There is a possibility that the blade of a small diameter bends depth of 1.5 ~ 1.0N it takes to turn while push the dial internal mechanical.
	Milling Chuck	Equipment for cutting by attaching a blade machining centers and milling machines. Being used (DIN standard, Germany) and HSK (bottle grip taper) BT is the shank.
	Mold base	Ready-made material for making molds. Yes processed six-sided advance, and those that were able to use the reference plane and finish clean roughness of the surface and the perpendicularity of the surface Y and X.
N	Non-magnetic	Those which do not stick to the magnet is not affected by the magnetic force. NISSIN so we have patented, there are times when hitting patent infringement sale and use of non-magnetic stylus Nissin Sangyo Co., Ltd. other than the non-magnetic stylus. Please note that it is not a non-magnetic return, even wrote "carbide" and "SUS440 (stainless steel)" in the specification notation of third-party products.
	Non-magnetic cemented carbide	Cemented carbide is a metal chemist Shurotta of Germany (Schroeter) has developed the process in 1923. There is also a 9 hardness of an alloy was sintered as a binder cobalt (Co) tungsten carbide in (WC), but it is brittle materials to shock. It will be attached to the magnet in this state, but it will change to a non-magnetic and chemical treatment in place of the Ni Co.
	Non-electric plating solution	And it is also called the Electroless nickel plated. It is a non-electric nickel plating solution formally Kanigen is a trade name. Nickel plating normal deposit iron and nickel ions by applying an electric charge, but there is a drawback to focus on the corners and edges of the electrical properties. There is no plated plaque-free solution power nickel-plated, so processing method is immersed in the nickel-containing solution, the plating is also capable of controlling the thickness of 1μm to be able to apply to the back side that has never occurred in the nickel plating.
	Nickel-plated	On standing in the air as the iron oxide and lead to (Fe2O3). Process to issue gloss by coating a nickel film on the surface in order to avoid oxidation.
P	Probe	Equipment that is attached to the spindle of the machining tools, measuring the size and position of the workpiece by applying the workpiece measuring element of the tip. Generic point finder, centering gauge swing type, such as centering gauge.
R	Repeat accuracy	Position is also changed measurement part of the measuring instrument touches the measurement object, is represented returns to its original position after being released from the object to "degree". It can be said, for example, if the point finder, even if tilted standard stylus is touching the work, the degree to which returns to its original position after also released from the work is so ± 0.5μm, and has returned to its original position almost.
S	Shank	Part that is attached to the spindle of the machining tools. BT shank and HSK shank (there is a tapered, conical ones), there MT shank and (Morse taper) in addition to the straight shank.
	Scroll chuck	Device to grasp the work attached to the spindle, such as CNC lathe.
	Stylus	At the contact portion of the tip three-dimensional measuring device for machining tools of the (probe), those of the thin rod-like. Both the feeler call, measurement is performed by exposed to the workpiece this part.
	Sub-zero treatment	When the quenching alloy high carbon content, may austenitic structure remains in the martensitic structure, the dimensional change of the product occurs in aging. To avoid this, products using high carbon steel, precision parts hate aging of the dimensions, in particular, By performing a sub-zero treatment to a cooled (-70℃) 0 degrees over liquid nitrogen immediately after quenching, to martensite and residual austenite.
