Rule sound 1, channel shedding: fatigue wear; replacement of bearing 2, foreign matter causes channel corrosion, indentation, scars: removal of related parts; use of clean grease irregular irregular sounds 1, excessive clearance: focus on cooperation and selection Clearance 2, steel ball scars: steel ball exhaustion or foreign body jam; replacement of bearing 3, foreign matter intrusion: removal of related parts; use of clean grease strong metal sound 1, lubricant deficiency: make up or use suitable lubricant 2, abnormal Load: Select suitable equipment clearance and pre-tightening force 3, poor assembly: improved machining accuracy of the shaft; improved equipment method abnormal temperature rise 1, lack of lubricant; or not suitable: add lubricant or select suitable lubricant 2, cooperation Surface creep or sealing equipment is too large: the outer diameter or inner diameter of the bearing is corrected; the sealing method is changed. 3. Too much lubricant: reducing lubricant lubricant leakage, large discoloration, foreign body aggression: removing related parts 2. lubricant More: Reduce the reverse oscillation of the lubricant shaft. 1. Poor assembly: Improve the machining accuracy of the shaft; Improve the equipment method 2. Invasion of foreign objects: Clear the related parts; Apply clean lubrication 3, shedding: tired off; replace bearings

Twist Drill Bit

The twist drill is a Tool used to drill round holes in the workpiece by rotating cutting with a relatively fixed axis. Because of its chip slot into a spiral shape and the shape of the twist named. Spiral grooves have 2, 3, or more grooves, but 2 grooves are the most common. The twist drill can be clamped on manual or electric hand-held drilling tools or on drilling machines, milling machines, lathes or even machining centers. The bit material is usually high speed tool steel or hard alloy. Standard twist drill: The twist drill consists of the shank, neck and working part

We have five different materials,HSS-CO8%,HSS-CO5%,HSS-M2,HSS-4341,HSS-4241.From left to right there are from high quality to low quality.
