As a result of the complexity of cutting tool application, major builds the invalidation form that grinds a center to must grind cutting tool according to be being repaired seasonable nap is repaired grind plan, dog the use effect of cutting tool repairs the common cutting tool material in grinding to have in cutting tool: High-speed steel, pulverous metallurgy high-speed steel, hard alloy and PCD, CBN, cermet exceed hard data. High-speed steel cutting tool sharp, tenacity is good, sex of tall Dan Ren differs hardness of hard alloy cutting tool. The density of hard alloy cutting tool is more than high-speed steel cutting tool apparently. These 2 kinds of material are the broach, main material that wrings knife, milling cutter and tap. The function of pulverous metallurgy high-speed steel uprights between afore-mentioned both material, basically use at making thick milling cutter and tap. High-speed steel cutting tool is good because of material tenacity, reason is not quite sensitive to colliding. But hardness of hard alloy cutting tool is tall and fragile, very sensitive to colliding, point skips easily. So, be in long in grinding a process, operate and must place of cutting tool to hard alloy very careful, prevent the collision between cutting tool or cutting tool to fall fall. Because the precision of high-speed steel cutting tool is mostly opposite inferior, its are repaired worry a demand not tall also, plus its the price is not high also, so, a lot of him manufactories set cutting tool workshop to undertake repairing grinding to its. But hard alloy cutting tool often needs to send major to repair grind a center to undertake repairing grinding. According to home certain cutting tool repairs the statistic that grinds a center, sending the 80% above in building cutting tool is hard alloy cutting tool. 2, tool grinding machine because cutting tool data is very hard, so, can use grinding to change its external form only commonly. The production in cutting tool, repair the common tool grinding machine in grinding to have the following kinds: 1.

Slot grinding machine: Rub the broach, chamfer that establishs the cutting tool such as milling cutter or back. 2.

Grind vertex angle machine: The cone-shaped vertex angle that worries bit (or say prejudicial hind horny) . 3.

Build horizontal blade machine: The horizontal blade of correction broach. 4.

The hand uses all-purpose tool grinding machine: The circle outside grinding, chamfer, back, vertex angle, horizontal blade, planar, before knife face. Commonly used at the amount the cutting tool with little, complex form. 5.

CNC grinder: It is 5 axes linkage commonly, the function is decided by software. Use at repairing to wear a multitude commonly demand of big, precision is high, but not complex cutting tool, like broach, establish milling cutter, reamer to wait. The main supplier of this kind of grinder comes from Germany, Switzerland, United States, Australia and Japan. 3, emery wheel 1.

The emery wheel that grinds a different capable person to pledge grinds bead to agree with grinding is different the cutting tool with qualitative material. The measurement wearing bead that the different position of cutting tool needs to use is different also, point is protected and machine the optimal union of efficiency in order to ensure. Alumina: Use at grinding HSS cutting tool. Cheap of emery wheel price, easy amend different species to be used at repairing to grind complex cutting tool (corundum kind) . Carborundum: Use at amending CBN emery wheel and diamond emery wheel. Boracic) of CBN(cubic carbonization: Use at grinding HSS cutting tool. Price is high, but durable. On international, emery wheel expresses with B, be like B107, among them the 107 size diamond that express the diameter that wear bead: Use at grinding HM cutting tool, price is high, but durable. Express on emery wheel with D, be like D64, among them the 64 bulk that represent the diameter that wear bead. 2.

Appearance the different position for convenient grinding cutting tool, the figure with due and different emery wheel. The most commonly used have: Parallel emery wheel (1A1) : Grind vertex angle, external diameter, low-necked. Dish form emery wheel (12V9, 11V9) : Those who grind helix chamfer, milling cutter advocate, deputy cutting blade, the need after the emery wheel such as the blade that repair a horizontal stroke passes the use of period of time amends its external form (include planar, angle and round horn R) . Emery wheel often must be used clear stone is wearing stuff between bead cut bits to clear in order to increase the grinding capacity of emery wheel. 4, repair the cutting tool with grind a standard to whether have good grinding a standard is to measure to repair grind the standard with whether professional center. Long grind a standard in, stipulated different cutting tool differs in cutting commonly the technical parameter of its cutting blade when material, include blade dip, vertex angle, before horn, hind horn, pour blade, pour arris to wait parameter a moment (in hard alloy broach, make the working procedure of edge passivation cries " pour blade " , the width that pours blade and be concerned by cutting material, be in commonly 0.

03-0.

Between 25Mm. Go up in arris edge (point of a knife is nodded) the working procedure that pours wine cup cries " pour arris " . Every professional corporation has what he is summed up for years and get to repair grind a standard. The distinction of HM broach and HSS broach: HSS broach: Vertex angle is 118 degrees commonly, be more than edge of 130 degrees of; sometimes sharp; is right precision (blade tall difference, symmetry, Zhouxiang is jumpy) the demand is relatively low. Horizontal blade has a variety of long ways. HM broach: Vertex angle is gotten for straight chamfer of 140 degrees of; commonly often be 130 degrees, 3 blade are gotten it is 150 degrees commonly. Edge and point of a knife (on arris edge) not sharp, often by passivation, or say blade and; pouring arris is tall to precision requirement. Horizontal blade often is repaired S- form, with benefit at breaking bits. Hind horn: Of edge hind horn to cutting tool character is very main. Hind part is too large, blade empty skips easily, easy " plunge into a knife " the part after; is too small, chafe too big, cutting is adverse. Of cutting tool hind what horn follows diameter of sort of the cutting tool that be mixed by cutting material, cutting tool is different and different. Generally speaking, horn follows cutting tool diameter after greaten and reduce. Additional, by cutting material hard, criterion hind somes part is small, otherwise, hind somes part is large. 5, cutting tool detects equipment cutting tool detects equipment divides commonly kind: To Dao Yi, measuring projector and measuring instrument of all-purpose cutting tool. Pair of knife preparation that basically are used at the numerical control equipment such as machining center to Dao Yi (wait for) like length, also use detect angle, radius, a flight of stairs grows the function that waits for parameter; measuring projector also is to be used detect angle, radius, a flight of stairs is long wait for parameter. But afore-mentioned both cannot measure cutting tool commonly hind horn. And the majority geometry parameter that measuring instrument of all-purpose cutting tool can measure cutting tool, the horn after including. So, cutting tool major is repaired grind a center to must deploy measuring instrument of all-purpose cutting tool. But the supplier of this kind of equipment is not much, there is the product of Germany with France on the market. 6, repair the member that grind the equipment with best mechanic to also need a person to operate, repair those who worry skilled worker to groom nature is one of the most crucial link. Because the tool manufacturing industry of our country is opposite backward, add the serious deficient that professional technology grooms, cutting tool repairs those who worry skilled worker to groom can solve by him enterprise only. 7, the last word had repair wear device, detect the hardware such as equipment and long grind a standard, long after grinding the software such as mechanic, the long grinding work of accurate cutting tool is made can begin. As a result of the complexity of cutting tool application, major builds the invalidation form that grinds a center to must grind cutting tool according to be being repaired seasonable nap is repaired grind plan, dog the use effect of cutting tool. A professional cutting tool is repaired grind a center to also must sum up experience ceaselessly, ability builds cutting tool grind weller, more only! CNC Milling CNC Machining
