Vision to achieve precision reaming tool machining
In the design of industrial instrumentation, in order to enable components to accurately reach the desired location, the application adjustment device is commonly used method. However, the possibility of whether to adjust, but also on the corresponding parts in the production of precision can be achieved when.
When the use of sophisticated tools, their adjustment is mainly concentrated in the cutting and clamping time. In the cutting period, the floor of the processing error and error replacement of cutting elements can be adjusted to compensate. In the clamping time through the cycle of adjustment to compensate for the machine tool spindle and tool system, the radial runout and angular error. In R & D work, such as cutting part of the design must meet the HSK spindle carrying out a simple tool replacement can meet the general requirements of the function, just stretch out the length and tolerance have special requirements needed to make some adaptive purpose. In doing all of the consumption of such adjustments should be kept within a certain range, because normally only installed when the system will be similar to the adjustments.
In the adjustable cutting, you can observe different phenomena. When the work is often with the machine to adjust the corresponding associated measurement process occurs, and the parking and the resulting interruption in production, the adjustment will become a special kind of interference. The concept of modern tools and tool replacement devices must be designed to achieve the purpose of the use of simple, so that the machine eventually be able to improve economic efficiency and increase productivity.
Precision Reaming processing new ideas
Reaming is a widely used traditional craft methods, the metal material in order to achieve precision reaming purposes. Already processed to achieve a relatively small hole in the cutting depth and a certain degree of accuracy, this is the cutting tool of the two main tasks. Multi-cutting edge reamer for a long time was the only method of using this technology tool. Reaming tool in the development process, Mapal company’s use of cut-reamer is considered a landmark reform. In the chip separation and orientation, as well as for the range and accuracy can be achieved significantly higher cutting speed is concerned, has brought even greater advantage. In addition, the tool cutting edge may also be user-replaced, and make precise adjustments, eliminating the need for logistics services required for the grinding process of consumption.
In addition to higher accuracy than the components, and meet the requirements of this new configuration of the entire system is necessary. In order to have a common task of two kinds of adjustments to reduce to 1 species, on the basis of need in all accurately placed turret. The use of rotary and Taiwan, the re-adjustment of a few millimeters, you can adjust the required absolute precision hinge hole diameter. The time required for this purpose are still consuming far less than the use of two kinds of adjustment of the time required, because eliminating the need for multiple between the before and after the adjustment screws to adjust step by step. Under the multi-channel processing operations, and even no longer need to adjust this new type of tool in the turret, you can achieve the requirements of the established tolerances allowed. If this is a few millimeters precision machining, by means of tilt insert clamping gap, can make reliable tool clamping.
Replacement of an alternative re-grinding
To solve such a dilemma the other cutting-edge design is a multi-reamer. At this point, the first target can be easy and accurate replacement of the part cutting edge, Blade assembly unit (HFS) related to accuracy, stability, and multiple use, be given priority. In order to further improve the tolerance in a very narrow range of cutting edge within the processing of multi-reamer economy, developed for the replacement of the telescopic device Segment reamer. Especially in applications such as PKD, or a class of PKB expensive cutting material, diameter and then the possibility of adjustments to improve the use of this new tool when the cutting process safety and economy. For example, in the use of cutting-edge foundry PKD, or PKB hardened cutting edge for processing dealing with such a situation, be able to meet the kinds of cutting edge of best utilization effect. Furthermore, also according to the material and other conditions, adaptive products in diameter.
Reduce the parking machine
As already mentioned, make adjustments in the machine tool is particularly troublesome process, but also costly, because the adjustment lathe must stop, resulting in the production standstill. Machining crankshaft bearing bore cylinder block in a straight line boring bar is a very typical example, in the special machines used in the majority of the boring bar equipped with as many as 2 × 7 Ge cutting edge, the cutting edge in the machine was accurate adjusted and fixed, in order to prepare for the replacement of the cutting edge. At the same time to use the gauge in order to adjust for mm-level accuracy. This process consumes time as a number of different cutting edge and different, each cutting edge is about consumption of 2 ~ 3 minutes. If HFS replacement unit with the replacement of cutting-edge fixture becomes a simple and fast. In the machine out of a simple auxiliary adjustment stage, adjusting the cutting edge device in the replacement plug-in just the right height in order to facilitate replacement. When the end use of time, just replace the plug-in, each location required for the replacement time is about 30 seconds.
Security and savings solutions
With the new device and continue to develop processing techniques and access to additional performance, special tool you can test stand to be many new ideas. A typical example is the cylinder head valve seat in the processing of the majority of this seat be combined with the valve guide sleeve processing. Seat from time to time for punching processing, turning from time to time for processing applications is usually punching processing methods. Tool used by most of the valve ring can be processed at the same time, the three edges and corners. The edges of the critical tolerances to ensure tightness. So far, not only in the bottom seat, or in the rotary stage production, have failed to omit the precision of adjustment, adjustment of consumption can not be replaced. The new idea is simple tool that has the potential to reduce consumption, as well as most parts of the complex process is simplified.
