Honing machine introduction of knowledge: Honing Machine (honing machine): The use of the workpiece surface finish honing Power Honing grinder. Mainly used in automobiles, tractors, hydraulic parts, bearings, aviation and other manufacturing honing the workpiece hole. Honing machine has vertical and horizontal. Vertical honing machine spindle working stroke is shorter, for honing the cylinder and cabinet hole and so on. Inlaid with Whetstone honing head by the vertical placement of the spindle is rotated, while the hydraulic device drivers mainly as vertical reciprocating feed motion (see machine). Horizontal honing machine working stroke is longer, for honing hole depth of up to 3000 mm. Horizontal placement honing head does not rotate, only for axial reciprocating movement of the workpiece is rotated by the spindle, bed Central features supporting a workpiece support center frame and honing rod guide frame. In the process, the honing stone head in a radial expansion and contraction under the action of the feed mechanism, the workpiece machined to the desired step size. The new hydraulic honing machine honing head swelling and shrinkage. Honing machines are mostly semi-automatic, often with automatic measuring devices, but also incorporate automatic production line work. In addition to processing bore honing machine, there are other surface machining cylindrical honing machines, honing machines bearing raceway, flat honing machines and honing machines and other surfaces.
DC Power Honing supply has positive and negative two electrodes , the high potential of the positive electrode , the negative electrode potential is low, when the two electrodes connected to the circuit after the circuit between the two ends to maintain a constant potential difference is formed in the external circuit to the cathode the negative electrode current. The difference between the water level alone can not maintain steady flow , while continuing to help pump water from the lower to send uphill to maintain a certain level difference can form a steady flow of water . Similarly , alone electrostatic field generated by the charge can not maintain a steady current, and DC power supply means , you can use the non-electrostatic effect ( referred to as "non- static electricity " ) to the positive charge at the cathode of the lower potential the internal power supply to return to the positive electrode at a high potential , in order to maintain the potential difference between two electrodes , thereby forming a steady current. Therefore, a DC power source is an energy conversion device , which the other forms of energy is converted to electric energy supply circuit to maintain a steady current flow. DC power in a non- static electricity is generated by the negative point cathode . When the DC power supply and the external circuit is turned on, the power supply external ( external circuit ) , as driven by the electric force , formed by the cathode to the anode current. In the internal power supply ( internal circuit ) , the role of the non- static electricity so that current flows from the negative electrode a positive electrode, so that the flow of charge to form a closed loop. Linear regulated DC power supply steady flow Performance of the power supply itself is a significant amount of power of the force characteristic , which is equal to unit charge from the negative electrode to move the positive electrode through the power supply internal work done by non- static electricity . When the power supply provides energy to the circuit when the power P is equal to the supplied power of the force E and the current I between the product , P = EI. Another feature of the amount of power to its internal resistance ( short resistance ) R0, when the current I through the power , the power loss of internal heat power ( per unit time, the Joule heat generated ) is equal R0I. When the power of the positive and negative poles is not connected , the power supply in the off (open ) state, then the power supply potential difference between two electrodes is equal in magnitude on the power of the force . In the circuit state does not occur with non- electric energy conversion. When the load resistor connected to the power poles to form a closed loop , through the internal power supply current to flow from the negative cathode , then , the power provided by the power delivered to the external circuit EI equal to the power of UI (U is the positive power supply and potential difference between the anode ) and the heat dissipated in the internal resistance of the power R0I , EI = U IR0I. Thus , when the power supply to provide power to the load resistor , the power supply potential difference between the poles U = E-R0I.
