Titanium grinding wheel choice

Titanium relatively sticky, easy to stick on the cutting wheels, it is not suitable for stiffer wheel.
Wheel hardness is not abrasive wheel hardness, but a combination of abrasive hardness between. Divided into soft, soft, hard, hard few. Each is divided into several levels. Hard not falling abrasive grinding wheels, grinding swarf under easy to stick on the wheel, causing the surface burns; soft abrasive grinding wheel easy to fall off, do not burn the workpiece, but the wheel consumed faster.
In addition to the hardness of the wheel, the organizational structure was divided tight, in a total of 12 loose, tight structure difficult to heat.

Cutting wheel use of safety

cutting wheel use of safety:
(1) not near flammable materials.
(2) use to maintain good ventilation.
(3) the use of eye protection and safety of the face.
(4) Use safety gloves to protect you.
(5) sparks generated by friction away from your body and around.
(6) Do not wear a shirt, should wear long-sleeved clothes.
(7) Do not wear polyester clothing, polyester is a petroleum byproduct, is flammable.
(8) If necessary, you need a mask, when a large amount of dust.
(9) When the noise exposure level exceeds a predetermined threshold value should be carried to protect hearing.
(10) If the produce substantial vibrations, immediately stop the tool. Determine the cause and correct it before you can continue to use.
(11) Do not cut soft metal, soft metal film can accumulate in the wheel, it may cause damage or other hazards.
Safe use of grinding wheel speed
Strength grinding wheels grinding wheel quality index is the most important one. Safety should be the first place the wheel, and never careless. For the safe use of the wheel, it is printed with safety line speed indicator on the wheel. Especially the high-speed wheel, and more importantly eye-catching signs, must follow the signs on the wheel speed may not speeding when used. If the mark on the wheel is unclear or no flag, the box re-testing to determine the safe use of the speed of rotation.

Grinding wheel dressing required Reason

In the grinding process, the abrasive cutting disc in friction, compression, its rounded edges gradually become blunt, or when grinding ductile materials, debris impaction often in the pores in the surface of the grinding wheels, the grinding wheel piece surface blockage, and finally the loss of grinding wheel cutting ability. At this time, will produce between the grinding wheel and workpiece slippage, and may cause vibration and noise occur, the grinding efficiency decreases, the surface roughness is deteriorated. At the same time due to the increased grinding force and grinding heat, causing deformation and impact grinding precision work, serious cases will make the ground surface burns and small cracks appear. In addition, due to the different grinding wheel and abrasive hardness uneven working conditions, so that the working surface of grinding wheel wear is uneven, ranging from various parts of the grain shed much, resulting in the loss of grinding wheel shape accuracy and surface appearance Viscosity surface roughness degree.
