For achieving the above object, technical scheme provided by the utility model is: a kind of CNC milling machine guaranteeing machining hole distance, comprise lathe fuselage, be positioned at the workbench on lathe fuselage and be arranged at the processing work platform on described lathe fuselage, described processing work platform includes a pair along the left console arranged side by side of X-direction above described workbench and right console, on this left console and right console, correspondence is provided with a left head and right head respectively, this left head and right head lower end are equipped with the milling cutter for processing work, wherein bottom this left console and right console, left skateboard and right slide plate lower surface are equipped with left step and right step accordingly, and described left console and right console are fixedly connected with by the connecting plate be provided with in this left step and right step, slide rail on the track of described left skateboard and right slide plate lower surface and described lathe fuselage forms and is slidably connected in X direction, lay respectively at the left column of described left console and right console both sides and right column and corresponding described left skateboard and right slide plate upper surface and form non-interference being slidably connected along Y-direction, described left head and right head form with corresponding left column and right column respectively and are slidably connected along Z-direction.
Further, the spacing between described left head and right head can realize adjustment by adopting the described connecting plate of corresponding different length installing hole spacing.
Further, described milling cutter comprises a cutterhead body in ratchet shape with several in angularly distributing and protruding the tool mounting portion being arranged on described cutterhead body edges, described cutterhead body central position is provided with a main shaft orientation hole, described tool mounting portion is provided with the screw for fixedly mounting cutter, described tool mounting portion comprises the thick cutterhead installation portion of spaced setting and thin cutterhead installation portion simultaneously, wherein be arranged on the cutter on described thin cutterhead installation portion to be less than to the distance in main shaft orientation hole and to be arranged on the distance of the cutter on described thick cutterhead installation portion to main shaft orientation hole.
Again further, the outer surface of described cutterhead is provided with one deck hard anodizing horizon, and the hard anodizing horizon thickness on described thick cutterhead installation portion is thinner than the thickness of the hard anodizing horizon on described thin cutterhead installation portion.
The utility model is after have employed such scheme, its great advantage is that Double-head works simultaneously, can processing length, single workpiece that pitch-row is identical fast, enhance productivity, and owing to being fixed by a plate bottom Double-head, better can ensure that the spacing of lathe in process between machining shaft is stablized constant, thus better ensure crudy.
