Adjust the cutting edge device to ensure the implementation of safe and energy-saving solutions

Reduce machine stoppages As already mentioned, the adjustment work in the machine tool is a particularly troublesome process, and the cost is very high, because the lathe must be stopped during the adjustment, resulting in production stoppage. The linear boring bar for machining the crankshaft bearing hole in the cylinder block is a very typical example. Most of the boring bars used in special machine tools are equipped with up to 27 cutting edges, which are precisely adjusted in the machine tool. And fixation, ready for the replacement of the cutting edge. At the same time, a gauge should be used in order to be able to make millimeter-level precision adjustments.

The time consumed by this process varies with the number of cutting edges, and each cutting edge consumes about 2 to 3 minutes. If the cutting edge is replaced in the fixture with HFS replacement device, it is simple and quick. On a simple auxiliary adjustment table outside the machine tool, adjust the height of the cutting edge device when the plug-in is replaced, so as to facilitate the replacement. When the use time is over, only the plug-in needs to be replaced, and the replacement time required for each position is about 30 seconds.

With the help of new devices and the additional performance obtained by continuing to develop processing techniques, special tools can get many new ideas on the test bench. A typical example is the machining of valve seats in cylinder heads, most of which are combined with valve guides. The valve seat is sometimes punched and sometimes turned. The punching method is usually used. Most of the tools used can process the three corners of the valve ring at the same time. The critical tolerance of the edges and corners must ensure tightness.

So far, the precision adjustment has not been omitted not only on the base plate but also on the turntable, and the cost of adjustment cannot be replaced. The high-precision tool with the hexagonal HX precision cutting edge brings a breakthrough. With the help of the shape of the turntable and the specially configured clamping device, in the case of simple rotation and replacement, the position of the tool does not need to be adjusted, which can ensure that the processing results required by the ordinary method can be accurately achieved again. The compact structure of this new device also brings other advantages. With a small number of structural components and quick insertion of the rotary table, the higher stability can be obtained, which increases the durability time compared with the adjustable tool.

In addition, little space is also very important, and structural components can be considered in the case of smaller sizes. If this valve seat machining tool is used in combination with a single-edge or multi-cutting edge structure type valve guide machining tool with an HFS replacement device, a high-precision machining tool will be produced, which can be used as a safe and low-cost alternative A solution was put into use. It is often difficult to find the easiest solution. The new simple tool concept shows that it is possible to reduce most of the consumption and simplify part of the complex process.
