The advantage that 5 axes machine

45kg) , the means that it can obtain treatment of 5 axes motivation to offer a kind of economy for 3 axes CNCCNC Milling is special machining center is in 5 axes at present in the machine tool that the United States sells, the 5 axes that have 15 above about machining center is primitive equipment manufactory. They belong to large facility for the most part, its power precision of powerful, treatment tall, price is high, be in commonly 10 thousand dollars of 5~15, taller even. Nowadays the cheapest machining center on the market, its start valence is in about 2.

50 thousand dollar is controlled. Special the main drawback of machine tool of 5 axes treatment is: Their athletic range is very narrow, general a 30 of ± of be confined to; The workpiece of cutting treatment must use need brow angle to handiwork locates 2 times and be started again. And, the tigidity of this kind of machine tool is inferior to be the same as dimension and the 3 axes machine tool that are the same as a type. In recent years, a lot of companies begin to use special 5 axes machining center, the workbench combination of its bend inclined workbench and milling machine is installed together. Although this kind of spare parts dimension that the machine tool can machine and weight are very finite, but this kind mixes model the price of the machine tool also is quite costly. Bend inclined rotates the bend inclined that workbench has manufacturer of much home machine tool to produce installation to go up in machine tool of numerical control of 3 axes CNC rotates workbench. Simple whirl workbench already was sold in the market old, apply at widely worldwide inside small-sized with job shops of large scale computer, use at the graduation of the spare parts, undertake all sorts of machine process an operation. Bend inclined rotates workbench can make the spare parts rotates, can tilt by all sorts of angle, the cutting tool that is helpful for a machine tool nears the many treatment surface of the spare parts, achieve true the purpose that 5 axes machine. Bend inclined rotates the working face of workbench is relatively lesser, the type that can install clip to hold work is very finite, have certain restriction to the length of workpiece, width and weight. In addition, bend inclined rotates the volume of workbench itself is larger, held the working range with very old lead plane. The biggest bend inclined rotates workbench can hold lead plane even the working limits of 75% above. When undertaking heavy-duty cutting is operated, bend inclined rotates workbench does not agree with clip holds treatment part, because length exceeds 12in(1in=25.

The spare parts of 4mm) may collide the surface all round. Although, bend inclined rotates workbench is a very appropriate solution for small-sized to treatment spare parts, but today's client demand machine tool has bigger flexibility and broad process capability. If this is the method that only of 5 axes treatment can choose only, so job shops cannot process the work that exceeds their dimension and weight limitation. Graph this 2 large 3 axes CNCCNC Milling can change into a complete programmable inside 30min main shaft of accessory of head of treatment of machining center main shaft processes 5 rods the main good point of head accessory is: It can approach all points of limits of machining center work. The work measure that head of main shaft treatment machines to need does not have limitation. Today, the company of a few United States, Italy and Germany is made and sell programmable main shaft to machine head accessory rarely only, they are used at large 3 axes milling machine. If install reasonable word, heads of these main shaft treatment are quite reliable still, machine precision will very tall, just the price is more expensive. As a result of their dimension and weight problem, its do not agree with installation arrives on medium, small-sized machining center, agree with only milling machine of type of large dragon door. And installation is permanent, the production with technical requirement and assemble. The price of accessory of head of treatment of this kind of main shaft is 17.

10 thousand dollars of 5~30, plus be debugged technically and install charge. Of only exception is, at present one kind can write annex of head of form main shaft completely, use it to be able to transform machine tools of any numerical control of 3 axes CNC machining center of genuine 5 axes linkage. If add to be able to tilt,90 ° of ± are mixed rotate the function of 360 ° , its cutting tool can be close to the any inside limits of machining center work to machine a dot. Because this is planted,distinctive treatment head shift goes to the lavatory, can go up to the machine tool in the installation inside 30min, make the client can achieve precision of 3 axes milling machine already thereby tall, tigidity is good with the good point with cutting sharp speed, and after can making accessory arrives in installation on the machine tool, finish the job that 5 axes machine, for example the treatment of outline appearance, bore and model antrum recess treatment. Its charge rotates with inclined of large do all one can roughly the cost of workbench matchs. The applied domain with the specific to some kind advantage that 5 axes machine after with 5 axes process capability undertakes an analysis, discovery uses 5 axes treatment to be able to think die manufacturer brings huge benefit. Use a flat bottom to carry milling cutter, hold perpendicular position to complex treatment surface, can reduce handling time substantially. The diameter throws step cutting and this positive result is achieved, because this is planted,treatment means can decrease in workpiece apparently frequency taking a knife. This treatment principle applies to the flank milling treatment that takes angle appearance as much. This kind of craft also can eliminate the costal state lines that establishs milling cutter to machine place to cause by ball end, achieve relatively good surface quality, because clear,cut down the surface and addition artificial milling and manual work quantity. Processing technique solves 5 axes to be in what mixed point of view locates place needs again to move trial assembly to get stuck for many times besides workpiece. This not only managing time, and still reduced an error greatly, and managing the requires high cost such as the tool clamping apparatus that place of installation work take one's place needs. It makes the machine tool can machine complex part, this uses other method to do impossibly, include complex the bore that needs normally apparently, model antrum recess and taper treatment. 5 axes treatment is passed use shorter cutting tool, but one-time the treatment that completes whole part, do not need to hold card again or use congener what what need in 3 axes treatment is longer cutting tool, and can be inside shorter time hand over a completed project, the exterior quality of the spare parts is better also. Because cutting tool passes pivot fulcrum outspread installation, because this is fundamental accessory with main shaft, should machine a mould inside model when antrum, undertake milling is machined outside the route that still can provide in lead plane actually.
