Although cast iron is a very common and widely used material, there are also many problems in hole machining: the casting process is unstable; the quality of hole machining is difficult to guarantee; the thermal conductivity of vermicular graphite cast iron is low, and the heat in the cutting area during machining It cannot be discharged, and the excessive temperature causes the tool life to be greatly reduced. Do you also have headaches because of these problems? This issue will take you to break through! ISO9001 Approved Manufacturer of zinc flake coating
The problems of cast iron hole machining can be summarized into three aspects:
First, the inclusions and pores on the casting surface will cause instability in the machining process, abnormal tool damage, and unpredictable life, which is a major hidden danger in batch processing.
Second, the quality of hole processing is difficult to guarantee, mainly because the orientation of the drill bit is unstable, resulting in the hole’s geometric tolerance not meeting the requirements.
Third, the thermal conductivity of vermicular graphite cast iron itself is relatively low, and the heat in the cutting area cannot be discharged during processing. Excessive temperature will greatly reduce the life of the tool and increase the production cost. ISO9001 Approved Manufacturer of zinc flake coating
In response to these problems, the editor checked a lot of information and found a HPR solid carbide drill from Kennametal, which was born to solve these problems. After reading the following analysis, you can also score together.
First of all, it has excellent wear resistance, and the unique multi-layer AlTiN/AlTiSiN coating can withstand the extreme friction and high heat conditions encountered when machining cast iron, and it is not a problem to deal with inclusions and pores.
Secondly, its drill tip is specially designed with low thrust, even if the clamping conditions are not ideal, or thin walls are processed, or the spindle power is limited, the straightness of the hole can be maximized and the processing quality can be guaranteed.
Finally, its chip flutes are double-enhanced with ultra-high polishing and widening cross-sections, which can basically achieve worry-free chip evacuation, which can help to remove heat from the cutting area. Coupled with the patented design of the fillet radius, the tool life is further extended and the drilling quality is improved. ISO9001 Approved Manufacturer of zinc flake coating
Maybe some friends want to ask, it sounds pretty good, won’t it be just on paper? Of course not, the editor also did a comprehensive investigation.
Let’s first look at a difficult vermicular graphite cast iron machining. The product that needs to be processed is the diesel engine cylinder head. The original product life is unstable, which affects the efficiency. After using the HPR solid carbide drill bit, the efficiency is significantly improved, the material removal rate is increased by 31%, and the tool life is increased by 32%, and it is stable sex is better.
In the processing of ductile iron materials in the automotive industry, HPR drills perform very well. Compared with the original products, the tool life is increased by 100% and the efficiency is increased by 80%!
Today, inflation and rising raw material prices have made the manufacturing industry more and more urgent to reduce costs and increase efficiency. Although the tool cost only accounts for a small part of the production cost, the improvement in efficiency is very obvious.
This HPR drill from Kennametal can be said to be stable and accurate in processing cast iron. How much do you give it? Welcome to leave a message for discussion. ISO9001 Approved Manufacturer of zinc flake coating。
