Sandvik to launch the new PrimeTurning ™ turning method and the CoroTurn® Prime A (left) and B (right) turning tools, a significant innovation in turning technology that leads to greater process flexibility And broader space for efficiency. PrimeTurning ™ machining methods and accompanying tools for the first time enable turning in all directions with a single turning tool. Manufacturers, particularly aerospace and automotive manufacturers Will therefore benefit.
CoroTurn® Prime Type A (left) and Type B (right) turning tools
Unlike traditional turning methods that have remained largely unchanged for decades, PrimeTurning ™ allows the machine to complete both the outer (forward and reverse), end face and profile turning operations with just one tool. The principle of this machining method is that the tool Cutting in close to the part grips and then removing the material as it moves toward the end of the part allows us to apply smaller declination angles, higher penetration angles and higher cutting parameters during machining. Of course, We can also do the same turning from the end of the part to the grip.
In some applications, production efficiencies can be increased by 50% or more by using a PrimeTurning ™ method that is completely different from conventional turning. Smaller declination angles and higher entry angles make chips thinner and wider , So that the heat and load away from the tip, thereby increasing the cutting parameters, to extend tool life.Because the cutting direction is gradually away from the shoulder, which avoids the problem of squeezing debris, and the crumb is common in the traditional turning and Headaches The PrimeTurning ™ approach reduces setup time and reduces machine downtime resulting in higher machine utilization and overall productivity, helping to make the aerospace and automotive industries more visible, In these industries, people need high-volume cylindrical turning, but also require frequent clamping and tool change.
Håkan Ericksson, Application Technology Manager at Sandvik Coromant, said: "Experienced operators know that using a smaller primary declination increases feed speed, however, with traditional methods of shoulder machining, they can only use about 90 ° of primary declination to avoid long and curved chips caused by small primary declination PrimeTurning's unique shoulder plunging and 25-30 ° primary declination provide excellent chip control and tolerance To make this a good solution to this conflict.This innovation provides an infinite possibility for efficient turning.It is not only a new tool, it is a new way of turning.
The PrimeTurning concept was first introduced with two dedicated CoroTurn® Prime turning tools and a PrimeTurning ™ code generator that provides optimized programming code and tips.The CoroTurn Prime inserts have three effective cutting edges / fillets per tip, one for Cylindrical turning, one for face turning and one for profiling, allows us to use each cutting edge more effectively and achieve longer tool life.
Currently we have two special inserts available: CoroTurn Prime A inserts with three 35 ° fillets for light roughing, finishing and profiling; CoroTurn Prime B inserts with a solid fillet specifically for In roughing.
Nine CoroTurn Prime Type A inserts and six CoroTurn Prime B inserts are available for ISO P, S (Heat Resistant Super Alloy and Titanium) and M (Stainless Steel), respectively. In the future, we will continue to expand our range of materials. We also introduced 52 tool shanks for these two inserts, including the Coromant Capto®, CoroTurn QS, and plain square shank.
The PrimeTurning ™ Code Generator not only ensures the best results, but also gives you the best feed rates and plunging angles to ensure machining safety.The ISO code it creates is compatible with a wide range of CNC systems.
