Snick of turning, mill basket special cutting tool, cubic nitrogen changes boron (CBN) cutting tool

The application of ball basket and compositive component ball basket, also be called " etc fast gimbal " it is the important part in car transmission system, its action is the motivation engine delivers drive wheel from transmission, travel of drive car high speed. Be used at the car wait fast gimbal type is very much, apply among them most is ball basket type fast gimbal and tripod type fast gimbal, basically have sliding sleeve, 3 cover to form of axis, transmission shaft, star, main part forms hard surface of form of cage, bell. Outside ball basket: The steel ball of this kind of ball basket is to be secured to place be covered in astral form and in 6 windows of a cage between bell form carapace, steel ball is covered in astral form and just is the place of the half each in bell form carapace, will define the action point of view with gimbal, smooth finishing makes the motion of gimbal resembles a helical gear same, the astral form that 6 steel ball promotes respective place respectively is covered and the lane in bell form carapace, just be the tine that pass steel ball and is not gear will deliver torque. Inside ball basket (trident type) : 3 balls sell type to wait fast there is steel ball inside gimbal, use 3 bearing that contain needle roller however, slippage can undertake in 3 orbit inside bell form carapace. Basically be used at 4 drive car inside ball basket, apply to turn round angle not big inside the position of ball basket, can mix upcountry outward slippage, the length of the generation when get used to drive axis to move in car with this varies. Inside ball basket (6 bead type) : Type of this kind of slippage fast gimbal product is having concept of a kind of different design, inside deliver torque by the steel ball inside inclined orbit, the property performance of the product is outstanding, those who exceed TJ type inside ball basket, but the distance of slippage is shorter, can solve the problem of noise, what use on 4 drive car is relatively extensive.

Ball basket ball basket the material of component introduces ball basket character main by crust (common calls bell form housing or outside annulus) , pass force steel ball, astral form annulus (form of common gradations marked on the beam of a steelyard is covered or inside annulus) comprise with the 4 parts such as cage. Globose carapace: Commonly used material is 55# steel character; The hardness after passing heat treatment is between HRC52-58, it is good to have tigidity, intensity is high, the advantage such as wear-resisting. Astral form is covered, cage: Commonly used material is 20CrMoTi character, the hardness after passing heat treatment is between HRC58-62, have better exterior tension and bend fatigue strength, core has enough strength and tenacity. Steel ball: Commonly used material is GCr15 character. Ball basket machines craft simply to be with globose carapace exemple: The globose carapace after inchoate classics overheat is handled uses grinding craft to realize high accuracy high quality to ask. Following: Forging (bought-in component) , thick car (outside round, inside aperture) , fine vehicle (outside round, inside aperture) , mill 6 raceway, rub spline whorl, heat treatment, the circle outside grinding, end panel, grind inside aperture, 6 lane, flaw detection, clear. But the ceaseless research and development as cutting tool material and practice, at present Hua Ling exceeds hard already developed it is OK to go out car generation is ground, the CBN cutting tool that grinds with mill generation, relatively at grinding efficiency city times rise, specific treatment craft is as follows: Forging (bought-in component) , thick car (outside round, inside aperture) , fine vehicle (outside round, inside aperture) , mill 6 raceway, rub spline whorl, heat treatment, clean, except scrap, external diameter good car, internal diameter good car, the raceway inside hard mill, assemble examine, pack.

Good car ball basket craft turning, mill the turning of cutting tool choice that cuts ball basket ball basket cutting tool: Use machining center to undertake turning to component more, ask in the dimension public errand to having Yan Ke, below operating mode of strong perhaps interrupted cutting, can use Hua Ling to exceed hard BN-H10 brand and BN-H21 brand to be opposite respectively ball basket component undertakes successive cutting and interrupted cutting, at the same time Hua Ling still can offer the good treatment program such as coating and Xiu Guangren.

Car cut mill of ball basket cutting tool to cut ball basket cutting tool: Basically use at globose carapace and astral form to cover the lane that go up (raceway) milling, with the window milling of cage, hua Ling exceeds hard CBN milling cutter to have taller high temperature wearability and thermal stability, point passes special processing technology, have higher blade ministry intensity and stability, cutting performance is steady, can control globose carapace strictly inside spherical spend with the coaxial of 6 lane, astral form covers spherical outside surface and 6 coaxial of lane to spend tolerancepublic errand requirement.

Mill cut ball basket cutting tool to be at the same time on the foundation of standard razor blade, china water chestnut exceeds return forcedly can offer Xiu Guangren and coating CBN bit (1) coequal feed of Xiu Guangren razor blade, acquire higher exterior quality; Coequal surface surface roughness, can use big feed, reduce sheet handling time, improve treatment efficiency; Note: Should not be in copying choose; Sexual machine tool mixes comfortable Yu Gaogang add workpiece.

Razor blade of CBN of the blade that repair light (2) flowing coating of coating razor blade and CBN mother capable person are ideal be united in wedlock, can acquire more exceedingly good cutting property, improve treatment precision and life.

Turning of cutting tool of CBN of coating CBN razor blade, mill the case that cuts ball basket (1) ball of turning of brand of BN-H10 of CBN cutting tool basket globose carapace:

Car cut name of ball basket work: Globose carapace machines operating mode: Successive cutting (ball basket face) workpiece hardness: Material of HRC58 cutting tool is qualitative: Parameter of BN-H10 TNGA160416 cutting: Vc=190m/min Fr=0.15mm/r, ap=0.15mm machines means: Do type cutting result: In the cutting parameter tower above of BN-H10 brand the circumstance of 11% plays bit of PCBN of brand of some Europe department, cutting tool cost is reduced 40% . (2) the ball outside turning of razor blade of BN-H10 C25 Xiu Guangren basket

Car cut ball basket to machine place: Outside ball basket external diameter (87.1) workpiece material is qualitative: S53C (Japanese brand, with home 53 medium carbon steel are similar) workpiece hardness: HRC58-63 machines working procedure: Model of finish machining razor blade: BN-H10 C25 (4165) CNGA120408S0015-4S (add Xiu Guangren) cutting parameter: Vc=146m/min, s=534, fr=0.45 result: Bright and clean degree achieve Ra0.8 less than, efficiency is 3 times what do not add bit of the blade that repair light. (3) basket star form covers globe of milling of CBN cutting tool lane: Material is qualitative: 20CrMnTi, workpiece hardness: HRC58-62, machine parameter: Vc=170m/min Fz=0.07mm/z, machine means: Do type cutting, cutting tool life: 4500. (4) mill of CBN cutting tool cut window of ball basket cage: Material: 20CrMnTi, workpiece hardness: HRC58-62, exterior surface roughness asks: Ra1.6, machine parameter: Vc=130m/min, fr=0.2mm/r, ap=0.3mm, cutting tool life: 2000.
