The application concept of new low-cost tools is particularly important in the processing of demanding or complex workpieces. Choosing the right tool, such as in the machining of the cylinder head valve seat and its conduit, can significantly reduce the cost of cylinder head processing. High-precision insert slots and a stable HFS connection are the unique features of MAPAL for valve seats and their conduits. Approximately 50% of the tool cost in cylinder head processing is spent on the valve seat of the powder metallurgy material and its conduit processing. As the requirements of the workpiece increase, it will inevitably lead to an increase in the application of high hardness powder metallurgy materials. In most cases, cemented carbide will no longer be suitable as a cutting material, but instead a more expensive PCBN. High precision requires further requirements for the tool: the seat ring must have a so-called sealing band with a very high angular accuracy in order to achieve a high compression-to-fuel ratio for the engine; the concentricity of the seat and the tube is also very important. To meet these requirements, there are a variety of tool designs to choose from. In the past, cylinder heads were usually machined on the assembly line. The conduit is machined by a reamer connected to the feed unit through a guide sleeve; the race is machined in the same process with an unfolding tool. However, the increasing use of smaller and smaller races, conduits and machining centers has made this tool design that has been stable in the past but takes up a lot of space. At present, the typical machining center tool design includes two knives: 1. Process the catheter guide hole and pre-process the seat. 2. Finish the seat and conduit. Originally used as a one-piece tool, the welded PCBN inserts used to machine the races were axially adjusted for continued use after grinding. With proper placement, HX inserts can be used 18 times to machine different chamfers MAPAL high precision and high stability HFS interface First, the MAPAL HFS interface is used to connect large race machining tools with elongated conduit reamer. This change makes the reamer more flexible with respect to the diameter and reamer form. The reamer is available in adjustable single-edged reamer and multi-blade reamer. Moreover, the HFS interface greatly reduces the difficulty of tool repair. Like the HSK interface, the HFS interface achieves extremely high stiffness and interchangeability through the tapered and end faces. Under the right conditions, it made it possible for a tool to be processed in one step for the first time. More cutting edges, longer tool life Then the optimization starts with the inserts of the machining of the machining knives, and the rims need to be machined inside and outside chamfers and sealing strips. We replaced the previously mentioned axial adjustment insert with a hexagonal HX PCBN insert with a total of six cutting edges. The race ring roughing insert is fixed, while the seal ring processing insert is mostly adjustable. These HX blades are all finely ground and clamped by high-precision insert slots and special pressure plates for maximum reliability. With the right choice of cutting material and cutting edge form, in some applications they can increase tool life from 2000 to 10,000 holes per blade. A blade can be used up to 18 times if the blade is arranged to use different positions when machining different chamfers. Significant savings Significantly reduced processing costs are the result of continuous development of the tool Due to continuous advances in machining and tooling technology, it has become possible to halve the cost per unit of cylinder head processing in the last decade. The processing of the valve seat and its conduit is a decisive factor. A recent example of using MAPAL's new technology to process such parts as a whole has reduced tool and machining costs by 70%.
