What precision tools are used for processing titanium alloys with high efficiency

It occurs relatively frequently in nature but rarely in pure form, and titanium is obtained through the use of complex production methods. This makes titanium an expensive and unique product.

　　 Despite this, its characteristics make this element a coveted commodity in today's industry. The purity is very good with good ductility and high durability at low density (60% compared to steel). Titanium has both corrosion resistance and temperature resistance. It also has good compatibility when in contact with the human body.

　　 The two main categories are different: titanium alloys, titanium alloys with other metals, and pure titanium with only a small amount of impurities.

　　 Challenge

　　 Poor thermal conductivity is one of the key challenges for all materials made of titanium (pure or alloy). The heat generated during the machining process is left on the tool, the cutting edge is heated, and the risk of cutting edge damage is high. As a result, precision tool life and process reliability are compromised. Difficult to cut materials processing

　　 Nevertheless, those who wish to obtain a good processing speed cannot avoid the cooling problem. Cooling is also important because titanium starts to burn at high pressures or temperatures above 300° (reacting with carbon, oxygen and nitrogen). This risk is even higher when cooling is interrupted. High elasticity is a problem, especially in pure titanium (1-4 degrees). It requires high shear forces and causes high cutting wear. The chip splits and flows only in a viscous and viscous manner. Sharp edges are suitable here, but they mean high wear and high risk of cutting edge breakage.

　　Solution

　　 Cooling System

　　 Just like in stainless steel, cooling is a key factor in determining the success of titanium processing. A better guarantee is that the cutting edge will not overheat. In Mikron Tool's 'crazy' product, whenever possible, it can be connected to the drill tip via a cooling channel, or it can be integrated into the shaft via a coolant outlet on the cone.

　　 Tungsten Carbide

　　The Mikron used in the processing of titanium carbide is resistant to heat shock through tools, and has high bending strength and fracture toughness at the same time.

　　 Geometry

　　 The geometry is designed in such a way that there is no need for high cutting forces. Despite the extreme toughness of the material, the tool has a high degree of stability and cutting edge to ensure good chip removal and good chip breaking from the processing area.

　　 coating

　　 Most products are equipped with high temperature resistant and oxidation resistant coatings, which are characterized by high wear resistance and low adhesion to metals. An exception is the micro-drill for deep hole CrazyDrill Flex. Since its geometry is particularly suitable for titanium, coatings can be avoided.

　　Processing

　　 In Mikron Tools, the recommended machining process is always based on the results obtained in actual tests. Our goal is always to obtain the best ratio of machining time, reliability and tool life. Specifically, this means relatively high cutting speeds and feed rates, while allowing proper cooling of the cutting edge and promoting continuous chip flow.
