In high speed cutting, PCD tools can get high machining accuracy and machining efficiency. At present, PCD tools are widely used in automotive, aerospace, electronics and other processing fields.
However due to the characteristics of PCD materials and processing limitations，traditional PCD tools are generally straight flute with welded blades, and the straight flute is far inferior to spiral flute both in cutting performance and chip removal, so that it seems powerless in some special processing occasions.
For this situation, Shanghai Nagoya has successfully developed the integral-type spiral PCD drills (reamer) through the self-developed equipment and processing technology, It can ensure that the integral-type spiral PCD tools hasμ-grade dimensional accuracy; moreover, the tool has a unique edge shape, part surface quality (RA≤0.2), good tool surface roughness and material wear-resistance, it can improves the processing efficiency several times and the cost of tools have decreased significantly.
The newly developed integral-type spiral PCD drills (reamer) can achieve the effects of high precision, high life and high efficiency in various advanced processing applications, and help customers achieve modern manufacturing mode of energy saving and environmental protection, high efficiency and high precision.
Application 1
Parts: turbocharger housing
work material: ADC12
Machine: BT40 Vertical machining center
Coolant supply: external cooling
Diameter of hole: ?2.5
Customer requirement: hole tolerance±0.05 hole roughness Ra3.2 or less, life: more than 30000 pieces.
Difficulties: tool life is required to be high, and it is difficult to meet the requirements of roughness and life due to sticking chips of solid carbide drill . The diameter is small, the traditional brazed PCD tip tools cannot be made.
Through customer’s test and comparison, the roughing is far better than the solid carbide spiral drill of A company without sticking of the tool when our integral-type spiral PCD drills processing D2.5 hole. Also the processing efficiency is increased by 2.5 times, tool life is increased by 10 times, and the tool cost of single hole processing is reduced by 50%, comprehensive advantages are very obvious!
Application 2
Parts: Air conditioning compressor housing
work material: ADC12
Machine: BT40 Vertical machining center
Coolant supply: external cooling
Diameter of hole: ?3.48
Customer requirement : hole tolerance±0.0075 hole roughness Ra0.8 or less, Greatly improve the processing efficiency on the premise of ensuring the processing quality.
Difficulties: The solid carbide reamer only meet the customer’s basic machining accuracy requirement, can not meet the requirements of increasing efficiency and improving speed. The diameter is small, the traditional brazed PCD tip tools cannot be made.
Through customer’s test, our integral-type spiral PCD reamer has been used for more than 3 months. At present, the tool edge is still perfect, the processing efficiency is increased by 3 times, tool life is increased by 7 times at least, and the tool cost of single hole processing is reduced by 50%, which not only completely meet customer’s the requirements of increasing efficiency and improving speed but also reduces the tool cost significantly ! ! One tool can be achieved all purposes.
