Titanium alloys used in aerospace, medical implants, high performance automotive parts etc., are selected for their outstanding strength to weight ratio and corrosion resistance. However after heat treatment, hardened titanium alloys are notorious for being extremely difficult to grind. Conventional aluminum oxide or silicon carbide wheels wear very fast, generate a lot of heat, often resulting in surface burning or micro chipping. Now, the new metal matrix CBN (cubic boron nitride) wheels are changing this. Zhengzhou Ruizuan Diamond Tool Co., Ltd. has developed an array of metal bonded CBN wheels specially designed to grind hardened Titanium Alloys quickly, accurately, and economically.
Superior Thermal Conductivity Prevents Surface Burning
The primary problem encountered when grinding hardened Titanium alloy is heat. Titanium poor thermal conductivity, leading to heat build up at the grinding zone. Vitrified or Resinoid conventional wheels just can’t handle it effectively and the result is burn marks, metallurgical damage, micro cracks.
The metal matrix CBN wheels from Ruizuan solve this problem with its superb thermal conductivity. The metal bond actually
acts as a heat sink, rapidly transferring heat away from the grinding interface, keeping the workpiece temperature within a safe range to avoid surface burning and metallurgical damage. As a result, the operator can achieve higher material removal rate without sacrificing part quality.
Excellent Retention of CBN Grits for Longer Wheel Life
CBN is the second hardest known material after Diamond, ideal material for grinding hard ferrous metals and alloys. However the effectiveness of a CBN wheel is determined by how well it can hold its grains. Conventional wheels tend to lose CBN grits too early, shortening their lifespan and increasing tooling costs.New metal matrix bond from Ruizuan holds the abrasive grits much longer. The controlled wear rate of the metal bond can expose fresh, sharp CBN grains but does not allow easy pull out. The result is significantly longer wheel life-often 3 to 5 times longer than the conventional ones. The advantage is enormous in high volume manufacturing; fewer wheel changes means less downtime and lower grinding cost per part.
Consistent Form Holding for Precision Grinding
Components made of hardened titanium alloy require tight tolerance and superior surface finish. Wheels that don't hold their forms over time will generate parts out of tolerance and result in scrap.
Zhengzhou Ruizuan Diamond Tool Co., Ltd. produces metal - matrix CBN wheels with excellent form - holding capability. The robust metal bond actually supports the CBN grains strongly, maintaining the wheel profile through long grinding cycles. This actually results in high repeatable accuracy and reliability across large production batches. No matter the work piece-a turbine blade, orthopedic implant or a structural aerospace component-a constant geometry can be achieved consistently.
Engineered Porosity for Chip Clearance and Coolant Flow
The introduction of engineered porosity in the metal matrix CBN wheel is another novelty by Ruizuan. Although metal bond is very strong, its density could limit the ability to clear chips and flow coolant in some instances, causing wheel loading and force build-up.
Ruizuan utilizes its proprietary manufacturing process to create a well-defined pore structure within the metal matrix. The pores effectively allow grinding chips to exit and ensure better coolant delivery. This greatly reduces loading, wheel force, heat build-up, and results in an outstanding surface finish. It is particularly useful when grinding Hardened Titanium alloys, which have a tendency to produce stringy, adhesive chips.
Summary
Hardened titanium alloys need no longer be a grinding bottleneck. Zhengzhou Ruizuan Diamond Tool Co., Ltd. has developed the new metal matrix CBN wheels which offer superior thermal conductivity to prevent burning, excellent grit retention for long life, outstanding form holding for precise grinding, and engineered porosity for efficient chip clearance.
