As the flying development of machining center market, its are correct operation method also jumps over forthcoming month to pay close attention to for people place. High speed machining center is used in the problem that should note uses an environment to be the service life that improves numerical control facility, general requirement should avoid the direct illuminate of sunshine and other heat radiation, should avoid too damp, dust overmuch or have the place that corrodes gas. Equipment should be far from the facility with large vibration, wait like equipment of punching machine, v. High speed machining center is unfavorable and long-term seal up for keeping, when machining the task, machine tool also answer fixed electrify, had better be weekly electrify 2 ～ 3, move for nothing every time 1 when the left and right sides, will in order to use the calorific amount of machine tool itself reduce the humidity inside machine, make electronic component does not send be affected with damp be affected with damp, also can discover in time at the same time without batteries n inadequacy calls the police, in order to prevent systematic set parameter missing. The filter of each lubricant, hydraulic pressure, baric to high speed machining center system or cent mesh undertake cleaning or change regularly; Undertake to hydraulic pressure system oleaginous assay is checked regularly, add and change hydraulic pressure is oily; Divide water filter to enrage to baric system regularly implement turn on the water. Undertake machine tool level and mechanical precision are checked regularly corrective. The method of correction of mechanical precision has soft hard two kinds. Its are soft the method basically is to pass systematic parameter to compensate, like guide screw backlash compensation, machine tool answers reference point position corrective etc; Good method wants to undertake when the machine tool heavies repair commonly, if have guide,repair blow, nut of ball guide screw deputy tighten beforehand adjust backlash to wait. Good power supply assures to fluctuate to avoid power source range is big (be more than ± 5% ) disturb the influence such as signal with likely instant, high speed machining center uses power supply of special railway line commonly (if divide a road to be used for numerical control machine tool alone from low-pressure distribution room) or add stabilized voltage device to wait, can reduce the influence of power supply quality and electric interference. Make the use of effective operating rules in numerical control machine tool and administrative field, should make a series of suit the operating rules of actual, effective. Lubricate for example, maintain, reasonable use the shift changing rule that reachs a standard to spend etc, it is numerical control equipment uses the main content that reachs management. Make and abiding by operating rules is one of important step that make sure safety of numerical control machine tool moves. Carry out a proof, numerous breakdown but by abide by operating rules and decrease or avoid to happen. CNC MillingCNC Machining
