Bead lathe Flange ndle k11, k12, k72 homemade lathe 80 100 16mm-19mm through hole shaft core hardened hard

Description

[Options]Option 1:Single 80-flange ndle (without bearing pulley, bearing, ck) (for k11, k12)Option 2:Single 100-flange ndle (without bearing pulley, bearing, ck) (for k11, k12)Option 3:Single 80 composite flange ndle (without bearing pulley, bearing, ck) k11, k12, k72 models universalOption 4:Single 100 composite flange ndle (without bearing pulley, bearing, ck) k11, k12, k72 models universalThe two most asked questions:Why is the shaft and the flange not welded, but using spot welding?Because of the interference fit of the ndle root ndle, the interference is about 0.05mm. The aembly proce is aembled with a 50-ton precision pre. The shaft and the flange are very tight and tight, and the concentricity of the shaft and the flange is also very good. The force can be reliably nsmitted to the shaft, and then added. Spot welding is equivalent to adding a layer of insurance. Since the shaft is made of precision seamle steel tube (g6 tolerance), its accuracy is very sensitive to temperature, especially the spot welding temperature is high. If it is slightly inadvertent, it will deform and lose precision. Spot welding is the most suitable way.That is to say, even if you buy it back, put the solder jointRemoveThe ndle flange can still be firmly matched with the shaft center, the flange will not fall easily, and the force is reasonable, safe and reliable.Therefore, our flange ndles are much better than the safety, stability and precision of the ndles.The price of this set of ndles is reasonable and affoble, and it is definitely lower than our price, but the same price is definitely better than quality and workmanship.If you need a certain amount or need a certain amount of long-term irregularity, you can negotiate with the customer service. The more the quantity is set, the greater the discount rate and the constant quality accuracy. Welcome cooperation.Default:and flange for clearance, with precision adjustment space, suitable for no finishing ability such as woodworking lathe, beading machine, woodworking A-axis, woodworking four-axis.This ndle is designed for woodworking lathe proceing wood. In addition, we do not guarantee any. For other uses or modifications, please consider it at your own discretion.【s】ndle axis: The shaft diameter is 25, the total length of the flange is about 205mm, and the through hole is about 19mm. Because the hole of the 80th is only 16mm, the overall through hole after loading the is about 16mm. Hardne: HRc 55-62°The ndle adopts numerical control machining precision s: the vertical angle of the axial center and the flange end face is ≤0.03mm, the axial center and flange concentricity is ≤0.03mm, and the axial outer diameter tolerance is g6.K11, k12 default flange fixing holes 3, suitable for s-centering linkage ck.K72 default flange fixing hole 4, suitable for single-action ck.80-card flange main shaft, after installing 80 cks, the overall through hole is about 16mm.100 flange ndle,After installing 100 cks, the overall through hole is about 18-19mm.The main shaft and the flange are equipped with interference fit (tight fit) + the end face is fixed by spot welding. The interference fit and the shaft center are more accurate. Due to the small amount of spot welding, the ndle is le deformed by heat and will not be deformed. Reduce the accuracy of the shaft.The prince of gap matching precision debuing:After installation, the holds the standard rod, rotates the ndle, carefully observes the eccentric direction of the ck, marks the eccentricity, and then moves the in half in the opposite direction.Then turn the ndle and observe the eccentricity. If there is an offset, adjust it again as described above until it is satisfactory.
