Are the swing tower of complex form or swing tower end panel had complex model how should be the face machined? Can reply on people horse of course, since swing tower, should use turning. But lathe tool of a little complex form is cut hard, as a result of complex form everywhere cutting condition is different, machine exterior quality, function of the processing that cut bits each different, often achieve the design requirement of blueprint hard. Be aimed at this problem, how should do? Company of 3 water chestnut developed a few special razor blade and arbor. Can offer user reference, draw lessons from, use. Lathe tool razor blade is commonly used horn of point of a knife is the square of 90 (S) , the triangle of 60 (T) , the lozenge of 80 and wait for 6 edges not conformal form (C, w) , 55 lozenge (D) , 35 lozenge (V) . Part of general point of a knife is larger, the strength of knife head is greater, copying ability is poorer. Part of point of a knife is smaller, knife head intensity is poorer, but in narrow airspace territory bigger, suffer interference less, copying capability is higher. Reason before when copying of swing tower of more complex external form, 35 lozenge (V) bit is the most commonly used. For success copying complex model face, the point of view with make special arbor make bit tilts proper is advantageous (graph 1) . 3 water chestnut designed tool cutting edge angle to be the 90 SVLP-SM with 117 30 ′ for copying of accurate and small-sized spare parts above all model with SVPP-SM arbor. Be like a graph before thick hind delicate spare parts is able to machine smoothly. Even the chamfer retreating a knife of workpiece and inside aperture pours horn mediumly to also can develop its process capability. The shop sign that holds razor blade presses international ISO standard is VPET and VPGT next receiving 0802 or 1103. V expresses horn of point of a knife to be the lozenge razor blade of 35. P expresses it is the horn after the law is of 11, only bosseyed spendable horny razor blade. E and G represent the accuracy class of bit respectively. G class is outside week surface is machined through grinding. And the E class razor blade here, its are all outside face all needs grinding to pass. ± is as high as than G class in requirement of ply respect precision 0.

025, and G class is ± 0.

13. Both of the others public errand is identical, be like inside receive a circle, height of point of a knife all is ± 0.

025. Place of G class razor blade is lay particular stress on to improve the SMG of function of the processing that cut bits with model of the chamfer that break bits, submitting three-dimensional and raised form is mould pressing is made directly piece, it and curvilinear edge are united in wedlock faultlessly, can realize the performance of the processing that cut bits with good repeatability and high accuracy treatment. Comfortable at machining nice spare parts (graph 2) . Place of E class razor blade is lay particular stress on to improve the appearance with model of the chamfer that break bits bright and clean spent SRF, it is machined to come out by grinding, have big before horn guides make a structure, can realize the fast face quality with good repeatability and high accuracy treatment. Afore-mentioned bit brands are the last the letter all is T, there is columnar opening in expressing bit, bosseyed belt pours wine cup, can be close through bolt solid on arbor. In brand of two kinds of razor blade 08 with 11 watches round size fact is accepted inside its for 4.

76mm and 6.

35mm. The following 02 with ply of 03 watches razor blade, respectively solid mix for 2mm, 38mm 3.

18mm, knowable these two kinds of bit are very little, belong to small-sized razor blade. Still should receive after the number of the brand 01 or 02 or V3. They express the radius of circular arc of point of a knife of bit, their real volume is 0.

1mm, 0.

2mm and 0.

03mm. Public errand of treatment of radius of circular arc of point of a knife of G class razor blade is 0 ～ - 0.

05mm, and public errand of radius of circular arc of point of a knife of E class razor blade is gone to by treatment further 0~-0.

Between 02mm. Lift a when machine among them: With SMG of VPGT110302 razor blade the chamfer that break bits machines the circle outside the workpiece of S45C steel, use cutting condition is; Cutting speed V=100m/min, cutting deepness Ap=0.

3mm, feed F=0.

05mm/rev, with oil of blame water-solubility cutting refrigeration lubricates, treatment is bright and clean degree amount to Rz=2.

9 μ . (graph 2) . If pursue,two kinds of chamfer that break bits recommend use likely cutting range 3. Treatment retreats knife chamfer to recommend radius of circular arc of use point of a knife to be R0.

The razor blade of 2mm. Because deepness of the biggest chamfer that retreat a knife suffers effect of treatment workpiece diameter, when the diameter is Ф 20mm, the biggest deepness can is 0.

5mm. When the diameter is Ф 25mm, the biggest deepness can is 1.

0. Nextpage differs two kinds the bit place of bits chamfer and precision and dimension all is VP15TF with material, namely matrix uses Fu of advanced Miracle technology besmear to exceed surface of TF15 of atomic hard alloy (Al, ti) N. Its hardness, tenacity, hear resistance, combinative strength is able to rise substantially. Can process steel widely, alloy steel, stainless steel, cast-iron, the material such as heat-resisting alloy steel. Resemble sphere for treatment in that way more complex external form, with end panel complex model face. Company of 3 water chestnut developed part of point of a knife smaller it is the razor blade of 25 only, nob letter is X (X) . Dimension can compare on one kind big. Model is XCMT150302, 04, 08.

(same razor blade differs 3 kinds radius of circular arc of point of a knife) . Arbor model is SXZCR/L. Get power to get used to each azimuth, use double clamp method to secure bit firmly. Pressing plate is made shorter, refrigerative fluid leads to edge without block ground. The treatment of a lot of spare partses in very comfortable gear-box (graph 4) . The model of the chamfer that break bits of bit is SVX, when be being machined to get used to complex curve, have performance of good the processing that cut bits from beginning to end, what slightness makes on bit is raised the curvilinear edge that machines with comfortable Yu Shangyang (graph 5) . Can machine with this cutting tool of 300 spherical. The smallest the smallest diameter that the ball radius that can machine can be workpiece (graph 6) . The end panel that the graph shows 7 times is complex appearance, needed to use left hand in the past, the right hand and finish machining 3 kinds of special cutting tool, finish with ability of 2~3 line working procedure. And the circle outside needing only with the bit cutting tool of new development is machined and go up raise treatment can be finished. Raise angle can be amounted to on 60 can shorten greatly so machine periodic time. Because bit has the good chamfer that break bits, bits is cut to be not twined when cutting go up in lathe tool, attainable beauty machines the surface bright and cleanly. Be like a graph to undertake end panel copy is machined all right smoothly 7, when the circle outside beginning one knife to cut, to check burr, cut answer greatly control is under half of radius of circular arc of point of a knife. When raise is machined on, because cut bits to contact length to lengthen, cut the in part that also should take radius of circular arc of point of a knife greatly the following. Interfere to shun cutting tool and work up establish a face to be nodded to 60 corner, distance of this Duan Shangyang should be more than 40mm. Raise machines the surface to be apart from to the deepness between the transverse plane on 60 cant on should be under 10mm. In addition machine precision to assure, head of a knife wears away, before dislocation changes another knife head to prepare to machine, position of proposal cutting tool should make preliminary adjustments again. The computer reachs the development of process designing technology, make more complex model the imitate treatment of the face and writing a program is not difficult problem. Appropriate cutting tool can make process designing simplifies greatly. The new-style cutting tool that because this is improved,uses reasonable design also is an important way that cannot ignore.
