Recently, a friend of gold powder made a difficult time when machining cast iron holes. 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? China Wholesale Manufacturer of plastic accessories
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, it is difficult to guarantee the quality of hole processing, which is mainly because the orientation of the drill bit is unstable, resulting in the hole’s shape and position tolerance not meeting the requirements. China Wholesale Manufacturer of plastic accessories
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. Too high temperature will greatly reduce the tool life and increase the production cost.
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 when machining thin walls, or the spindle power is limited, it can maximize the straightness of the hole and ensure the processing quality.
Finally, its chip flute is double-blessed by ultra-high polishing and widening of the cross-section, which can basically achieve worry-free chip evacuation, which can help to take away the heat in the cutting area. Coupled with the patented design of the fillet radius, the tool life is further extended and the drilling quality is improved.
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 processing. 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. China Wholesale Manufacturer of plastic accessories
