Introductive: Normal > to need clamping apparatus to secure work, with CNC lathe for, collet is the most commonly used clamping apparatus, its form and sort are various, make appraise remark with respect to the commonly used collet inside the factory below special case introduces simply, for do business or serving end reference is used. Normal >normal > places the introduction that holds power: Normal > collet is use fluid mostly will produce clip to hold stand, there are oil pressure and atmospheric pressure inside the factory, these two kinds are the most convenient automation clip maintains pattern. On the application of oily atmospheric pressure, must understand the following nouns and its physics significance first, ability is known how to apply. Normal >a.

Force: F unit is Newton (N) , or it is kilogram of force Kgf. Normal >b.

Area: A unit is M2(square meter) , or) of Cm2(square centimeter. Normal >c.

Pressure: The active force of P unit area, on physics, can use Bar to be an unit, normal > Bar is: 1 Bar=10, 000 N/m2 = 10 N/cm2. Normal > so, the basiccest pressure computation formula is P= F/A. Because inside the factory the habit uses Kgf to be power unit, because this is special, the unit conversion that concern the specification is as follows: Normal >1 Kgf= 9.

8Nnormal >normal >1 Bar= 10N/cm2 = 10/9.

8 Kgf/cm2 = 1.

03 Kgf/cm2normal >normal > to go to the lavatory on computation, use 1 Bar = 1 Kgf/cm2 only normally. Normal > oil pressure relies on to write oil pressure to the crock drives push-pull staff and produce clip to hold power namely (the 1) that be like a graph, differ along with the volume that writes collet, have the heart that do not have a top, what its place held weight to also have difference. The following form is with 100 million plain for the clip of the exemple cautious measures limitation. Those who need an attention is, clip holds force to be able to be followed write rotate speed to increase and decrease successively.

It is example with SMW, the graph of the force of hold sb under duress that each collet leaves at 6bar baric source and rotate speed (the 3) that be like a graph. Lane annulus pursues 2 graphs 3normal > collet applies: Normal > inchoate high speed is move collet to give priority to with the hand, along with write progress of science and technology to evolve up to now CNC lathe uses oil pressure or baric collet mostly, and the hand moves collet to be used to assist clip to hold more. And along with write treatment workpiece to differ, the application of collet is different also, general oil pressure is hollow the limitation that collet is pushed pull rod, its workpiece diameter gets the via bulk of condescend push-pull lever, it is with VT-36 exemple, push F91 of pull rod via, its machine workpiece diameter to must be less than F91, if use atmospheric pressure,diameter of collet criterion workpiece suffers via of itself of collet of be confined to, via heals big fair the diameter also can increase subsequently, because of baric collet clip holds power relatively oil pressure is little, if want to avoid workpiece surface to place an injury to also can choose baric collet, depend on treatment demand and decide. But because baric collet is monovalent taller, and extensive of oil pressure collet uses a sex wide, normally CNC lathe still is main clip to hold with oil pressure collet additional. Normal >normal >a.

The hand moves collet: Normal > is used mostly at high speed lathe, the model treats a spare parts treatment to give priority to, or use at main shaft B to carry auxiliary clip to hold. Normal > locks up type of the lock after type is reached minute ago; Clip claw divides 2 claw, 3 claw, 4 claw... etc, right cent is moved together reach sheet to use formula, machine demand and decide, commonly used 3 claw or 4 claw collet, 3 claw can process the work of homocentric circle, 4 claw can process eccentric work. Normal >b.

Baric collet: Normal > goes up silver is production ball screw, its workpiece is long and do not make workpiece surface is injured, main shaft around uses the baric collet of SMW. This is VTII-26/110YCV. Installation must notice lane annulus is opposite the position, do not make aerate the process produces flat phenomenon. Normal > a lot of sort, have generally hollow reach sincere collet, have minute of number that place claw likewise, also must cooperate workpiece to perhaps machine means or cost thinks choose to use, provide reference of example of collet of special oil pressure below. Normal >normal >a.

Graduation collet: Normal > circumgyrate type turning much face is special workpiece (for example: The) such as a powerful person of cross axle, electromagnetism, collet of graduation of by means of controls the turning aspect of workpiece, can need equipment elliptically a variety of special clip claw and time of contractible fluctuation makings. (This kind of collet requires crock of tie-in and special oil pressure, gasoline tank. ) [graduation collet] [collet head] Normal >b.

Collet head: Normal > is multi-purpose at machining arbor kind spare parts, general meeting cooperates to send filling system of makings machine and industry automatically, with 24HR full automatic production is given priority to, produce can Gaojuke reduces labour cost. Constant cent is its tie-in collet circle, all directions form, hexagonal etc. CNC Milling
