The boring of alveolus is machined

The installation of cutting tool is when boring alveolus, the most important is cutting tool of correct on machining center installation. In alveolus boring, the center of cutting tool is high it is the main factor that brings about cutting tool invalidation. If cutting tool is installed under the center tall, machine those who affect cutting tool function. Main show is in: Cutting blade is opposite at workpiece advocate hind horn is reduced, those who bring about cutting tool hind knife face and workpiece contact, make clash produces between bit and workpiece, when bit rotates, this kind of attrition can make point of a knife produces deviate further, bring about cutting tool to cut work greatly. After cutting tool horn decreases Xiaoshi, bit is opposite at workpiece before horn also increases, cause work of cutting tool scrape thereby, cause cutting tool vibration and attaint cutting tool. This kind of case is more severe when boring alveolus. Answer for installation of this proposal cutting tool center of summary prep above is high (but should be close to central tall) as far as possible. Can make cutting tool opposite so the law at workpiece backward horn increases, cutting condition gets ameliorative, if add man-hour to produce vibration, point of a knife can is down and to the center deflective, the center that approachs ideal thereby is high. Cutting tool also can be exited slightly, reduce the possibility of the workpiece that cut an injury. In addition, the horn before cutting tool also will be reduced, can stabilize actuating pressure so. If before horn reduces 0 ° , can generate too great actuating pressure, bring about cutting tool invalidation. It is so when boring alveolus, should choose before horny boring cutter, when the alveolus of boring 1mm, the diameter of boring lever has 0 only.

76mm, make force of cutting of cutting tool susceptive is reduced. 2.

Cutting speed and feed speed maintain appropriate cutting rate and feed speed to be able to reduce cutting force, cutting speed of the standard and feed speed are unwell be less than the alveolus under 6mm at boring diameter. If boring diameter is the alveolus of 1mm, circumferential cutting speed is 450sfm, this should achieve 43000rpm with respect to rotate speed of main shaft of requirement machine tool, because this has the machine tool of high rotate speed to just can use this speed to undertake machining only, when treatment not be patient of is oscillatory, otherwise cutting tool Yi She is broken. More practical method is to use the 6000 main shaft rotate speed that turn, circumferential cutting speed has 63sfm only. To reduce cutting force, feed speed must not exceed 0.

0005ipr. Below the circumstance that reduces in feed speed, the exterior quality of attainable ideal. When boring aperture is the alveolus of 1mm, chosen boring cutter diameter is less than slightly 0.

76mm, hole depth of the biggest treatment is 8mm, grow diameter comparing to be more than 1: 10, because the speed of the biggest cutting of this boring cutter is 60sfm, feed speed is 3ipm, so normally grow diameter comparing not to suffer 4:1With 6:1limitation. When making a diameter be the boring cutter of 1mm, because its end blade is mixed,bore hole the reason of clearance, diameter of its cutting tool should is less than slightly 0.

76mm, boring deepness can amount to 7mm, its grow diameter comparing to be more than 10. 3.

The eduction that cuts bits is when boring alveolus, the effective eduction that cuts bits is crucial. When treatment, because cutting tool is inside aperture, cutting fluid arrives at cutting blade very hard, cause difficulty of the eduction that cut bits, affect cutting tool life. To solve this one difficult problem, the bit that development of manufacturer of a few tool gives slot of refrigeration of first flank of cutting of a kind of edge, make cutting fluid flows to cutting blade directly, prevent to cut bits to jam damage with cutting tool. 4.

The clamp of cutting tool is implementation fast, go to the lavatory and can repeat installation, a few manufacturer designed specific knife mix, become loose in order to avoid bit, basically include locking pressing plate and head of water guttate small boring cutter. Compare with photograph of common round razor blade, head of water guttate boring cutter has a lot of advantages. With grooving treatment is exemple, when workpiece of cutting tool bring into contact with, can rotate with as same as workpiece rate, if use round bit, the locking bolt on arbor is the spare parts that prevents bit roll exclusively, and the appearance of head of water state boring cutter can make bit tightens solid to be on arbor, and head of water state boring cutter can make bit automatic centering. If be a diameter 0.

The boring cutter outfit of 76mm searchs on knife clip in the middle of the heart is high, if locking collet, cutting tool will be rotational, make its under the center tall, to prevent this kind of situation, install what when placing boring cutter, should make to be located in central tall above, can make boring cutter returns central position when locking collet. The following should notice when boring alveolus: Install boring cutter correctly, center of made summary prep above is high; Use before horny razor blade; Use minor cutting rate and feed; Eduction of use cooling fluid cuts bits; Cutting tool installs clip to answer reliable.
