Friends of the three leading domestic wholesale activities carbide rotary top inlaid alloy live top

Friends of the three types of brand models MT4 live center carbide inserts are precision 0.005 caudal large end diameter 30 (mm) Overall Length 170 maximum outer diameter 75 (mm) for machine tools lathe Material 45 steel load carrying capacity of the material Carbide End Fitting vertebra number Mo's No. 4 Name: Friends of Rotary's top live top Specifications: Morse cone (MT) unit: taper correspondence: 0: Diameter of large end Φ9.045, taper: 1: 19.212 on the 1st: large end diameter Φ12.065, taper: 1: 20.047 on the 2nd: Φ17.78, taper big end diameter: 1: 20.020 on the 3rd: large end diameter Φ23.825, taper: 1: 19.922 on the 4th: the big end diameter Φ31.267, taper : 1: 19.254 on the 5th: Φ44.399, taper big end diameter: 1: 19.002 on the 6th: large end diameter Φ63.348, taper: 1: 19.180 events leading machine tool rotary top use is mainly used lathe shaft , with the center hole location, so that the part to be machined to obtain a high dimensional accuracy. Events leading specifications lathe top, there are two: the head rotating top; monolithic top first with bearings, positioning accuracy slightly worse, but the rotation is not easy to heat the second is an integer of iron bars, but the positioning high precision, the top part of the rotation of the friction and heat. Inside the spindle taper Morse What is the role? Machine with a rotating spindle, such as drilling, boring, internal circular grinding, cylindrical grinding, lathe, hobbing, the spindle end, in general, Morse taper. Drilling, boring, hobbing machine used to drill and install the tool, the circular grinding mill fitted with Morse taper because taper Morse taper hole about 3 degrees, the centering is good, there are self-locking performance. Milling cutter is generally easy assembly and disassembly, only in a small milling tools, such as the X8126, only with Morse taper. Cylindrical grinding, is used to hold the top, because artifacts are generally two top holes. The effective length of the cone Morse taper, are generally much smaller than the length of the spindle, so Spindle bore tapered bore only need to precisely machined cone. Lathe used chuck workpiece clamping, but small and medium lathe spindle ends, as production has Morse taper. The first use, is used to install the mandrel, the detection precision machine tools used; the second use in the production of some of the need for accurate repeatable positioning jig as positioning reference; and third, the lathe in expanding the scope of use, of course, direct chucking tool. Events leading it is a small precision lathe attachment for high-speed cutting essential.
