1. Boron carbide sand blasting nozzles
they have a service life 4-7times of sintered tungsten carbide
nozzles, but their shock resistance is not as that of sintered
carbide nozzles, so are suitable to serve under wear, stable
atmospheric pressure and medium shock.
Specification:
Grind resistant, do not active with acid, low & high
temperature resistance,
The density> =2.46g/cm3;
Hardness> =3500kgf/sqm, bending resistance: ≥ 400Mpa
Melting point: 2450degree
And now boron carbide nozzle is instead of hardness alloy, Tungsten
carbide nozzle, silicon carbide sandblasting nozzle.
The working life of boron carbide nozzle is 500-1000H
The size can be customized as per drawing
2. Sintered tungsten carbide
products including various sand blasting nozzle, high-pressure
water spray nozzle, high-pressure water cutting nozzle, bars,
sheets, sealing rings, punching die blocks, glass cutters, etc.
We are able to produce tubes with diameter of 200mm and length of
300mm, for rings, size can be diameter up to 320mm and length to be
200mm.
advantages on Tungsten carbide sand blasting nozzles :
1. very high hardness.
2. stable working effort during blasting.
3. long sizes are accetable.
4. very good prices with quite fast delivery.
5. special sizes with drawing are acceptable.

3. Silicon carbide sand blasting nozzles
have middle wear resistance and anti-shock ability compared with
boron carbide and tungsten carbide, and much lighter than tungsten
carbides.

Alumina | 20-40 | 10-30 | 1-4 |
Tungsten Carbide | 500-800 | 300-400 | 20-40 |
Silicon Carbide | 600-1000 | 400-600 | 50-100 |
Boron Carbide | 1500-2500 | 750-1500 | 200-1000 |

01 Properly reducing the cutting speed and feed rate can prolong
the trial life of the milling cutter.
02 When working, it is necessary to add cutting fluid to protect
the cutting edge, which makes the cutting smoother.
03 When there is an oxide film or other hardened layer remaining on
the surface of the workpiece, it can be removed by reversible
milling.
INST RUCTIONS FOR USE
What buyers need to know about end mill selection and operating
instructions
01.
Before using the tool, please measure the tool deflection. If the
tool deflection accuracy exceeds 0.01mm, please correct it before
cutting.
02.
The shorter the length of the end mill sticking out of the chuck,
the better.
If the end mill sticks out for a long time, it is necessary to
reduce the rotational speed, feed rate or cutting amount.
03.
During cutting, if abnormal vibration or sound occurs, please
reduce the cutting speed and the cutting feedrate until the
situation improves.
04.
The steel cooling is preferably spray and air jet, which can
effectively improve the use effect of the milling cutter.
