Use at the big milling cutter of small milling machine

Till recently, those small-sized vertical in 30# taper main shaft undertake the workshop of treatment of end panel milling on machining center, still can use only lesser (diameter most greatly the milling cutter of 80mm) , this restricted the metallic purify rate of the machine tool. Achieve higher metallic purify rate with big diameter cutting tool, mean normally should use bed of large scale computer in order to deal with the large size of cutting tool (length and diameter) wait with tall weight. Nowadays, manufacturer of a tool developed a kind of weight the end panel milling cutter with lighter, more compact structure, diametical volume can believe 80, 100 with 125mm, suit to be used on the machine tool of 30# taper. Milling cutter of this kind of big diameter is designed, use in aluminium and cast-iron treatment, can produce the metallic purify rate with the higher milling cutter with commonner than the structure, smaller diameter. This kind of milling cutter is called milling cutter of Exocarb disk type, by OSG Tap&Die company (be located in Yilinuosi the Glendale Heights) of the city is made, useful the S that operates at rough machining and finish machining and the Pro that is used at finish machining operation only. S provide hard alloy bit, not adjustable; And Pro contain PCD bit however, can be in 0.

Undertake modulatory inside 100 limits, accordingly, the user is in arrive from a spare parts in the process of another spare parts, can maintain careful exterior surface roughness. The main distinction between this kind of new-style cutting tool and cutting tool of common 30# taper is, it has long and thin, weight qualitative cutter hub of steel of form of light, star, and a kind of more compact cutter hub and arbor union method, use 3 pin and not be normally key type is assembled (see picture) . The diameter is weighed for the S of 125mm cutter hub 2.

2 pounds, and the groovy cutter hub of same diameter hefts 7.

5 pounds. Because the design is clever, the cutter hub of aluminous qualitative milling cutter that new cutter hub is 125mm than the diameter even is even light, and its sale price is equivalent to latter 1/3 only. Cancel the key of cutter hub and arbor standard and keyway locking method, the metric length that makes make manufacturer general cutting tool (the place that contacts main shaft from cutting tool arrives the distance between blade of cutting tool cutting) reduced 29mm from 45mm. Reduced a knife to place medium metallic amount not only so, make the gross weight of cutting tool maintains thereby in 3.

5 pounds are controlled, because decreased,still hang the tigidity that extend length and raised cutting tool at the same time. The diameter is the cutting tool of 125mm, on the CNC machining center of a Brother company that provides BT30 main shaft, had a test through machining 7075 aluminium. 160 inches are in feed speed / minute, main shaft rotate speed is 8, 000 turn / minute below the circumstance, cutting tool came true to exceed 73 cubic metre inch / minute metallic purify rate. Design of astral form cutting tool provides 5 bit only, and groovier end panel milling cutter has 8 bit commonly. But, manufactory home emphasizes, the groovy cutting tool that the metallic purify rate of cutting tool wants to compare small diameter is taller. Apparent, 125mm cutting tool a bigger advantage is, in the course that cuts one knife, the user can be on the machine tool with lesser norms, from workpiece surface cut away more material, realize bigger productivity than small diameter cutting tool. In addition, the user can achieve a goal through one knife only, exempted the line of one or more planar joint that produces because of collateral cutting normally. Another advantage is, with weight the cutting tool with lighter, more compact structure replaces heavier groovy cutting tool, can reduce bearing of machine tool main shaft wear away. OSG discovery, a lot of companies now is not to reduce scope, change direction however use efficiency to compare expensive plant and dimension are lesser and more effective machine tool. They want to reduce the initiative investment of the machine tool, reduce floor space, save energy, all these point to the target at using small machine tool. In the meantime, they still want to maintain taller productivity, this kind of new cutting tool can help such workshop, tall productivity comes true on small machine tool. CNC Milling
