How to give your home a safe door lock?

Some friends often think of whether to match the door when purchasing the door lock, and ignore the safety and convenience of the door lock. Here, the editor of the door network suggests that you should consider the following principles when buying a door lock:

First, choose a brand-name lock produced by a manufacturer with quality assurance.

Second, pay attention to the lock that is the same direction as your door.

Third, pay attention to the width of your home's door frame, the ball lock and handle lock can not be less than 90cm door.

Fourth, special attention should be paid when installing the door lock: only the end with the insurance can be removed to install it. Never remove the end with the key. It is best to read the manual carefully.

5. Don't drop the oil into the lock. If the key is not flexible, you can put some pencil core scraps into the keyhole.

6. If the in-home insurance is inadvertently rotated 90 degrees in time to become permanent insurance, this can only be opened with a key. Simply turn the insurance 90 degrees counterclockwise to recover.

7. Do not wipe the lock body and handle with a damp cloth to avoid rust.

Eight, it is best to hold the handle when closing the door, screw the lock tongue into the lock body, then close the door and then let go, do not force the door, otherwise it will reduce the service life of the lock.

Superabrasives are tools used in precision grinding,precision cutting,precision polishing and precision drilling,like flexible diamond abrasive.Superabrasive materials attach to a wheel,blade and drill to make Superabrasive grinding wheels,cutting balde and drilling bit.The reason some abrasives are Superabrasives is due to their extraordinary hardness,unparalleled performance,and longevity.
What are Superabrasives?
Abrasives that belong to the Superabrasive family includes,Industrial diamonds: an industrial diamond is a non-gem quality small diamond that is for abrasives,cutting,and drilling tools.
Cubic boron nitride (CBN): Usually called CBN it is the second hardest cutting tool material after a diamond.
Polycrystalline: Is an abrasive material that has a multiple collection of crystal grain structures with individual orientations
CVD Diamond: These are synthetic diamonds made by a process known as chemical vapor deposition.CVD diamonds grow from a hydrocarbon gas mixture. They are extremely hard,have a high thermal conductivity that is five times that of copper. They also have broadband optical transparency,are chemically inert,and only reach graphitization at very high temperatures.
Nanodiamonds: These tiny diamonds are the product of a controlled explosion. Sometimes called a detonation nanodiamond (DND) or an ultradispersed diamond,as this is how they form.
Industries That Use Superabrasives
A great number of industries use Superabrasive grinding wheels and the coated abrasives subsection of the abrasives industry continues to grow. Industries that are prime buyers of Superabrasive grinding wheels are,

Aerospace

Advantages of Superabrasives
The advantages of Superabrasive grinding wheels are more than extraordinary hardness,unparalleled performance,and longevity. These three features of Superabrasives are the core of many advantages manufacturers gain by an aggregation of services that normal abrasives simply cannot deliver.
These include:
Less expensive tooling and fixturing costs
More wheels on the spindle,smaller wheels,multiple operations
Less floor space needed for manufacturing
Virtual elimination of wheel wear
Automated CNC machines,less labor intensive operations requiring less training
Consistent surface speed from part to part
Better overall throughput with fewer machines needed
Improved Material Removal Rates,Lower Per Part Abrasive Costs and higher speeds
With Superabrasives,production increased by automated CNC equipment,industries have found one way to compensate for the lack of availability of skilled labor. With fewer machines needed,so is fewer workers. With Superabrasives CNC,automation is more concerned with defining a manufacturing process using machine capabilities and mechanization. There is less concern on operator technique. A properly defined process,combined with automatic loaders make for equipment that is almost running itself.
Industry Outlook
Future growth of the abrasives industries will primarily be in Superabrasives. Currently,research and development of Superabrasives are taking place in the following areas.
Custom designed [hard to grind" materials in an increasing number of industries
Creep or deep feed grinding
High-speed,high-performance grinding of hardened steel
Form grinding,sometimes with electroplating,in high precision,high-removal,and high-surface quality applications
CNC-control of line grinding machines
Other abrasive technology developments with Superabrasives are likely to occur in using CVD for the best bonding of coatings to diamond wheels
