Equipment pictures (actual products may have some differences)

The SWH-8000 honing machine is mainly used for honing precision inner holes of hydraulic cylinders and other pipe fittings. After processing, high-quality geometric accuracy and surface micro mesh can be obtained (meeting the production and maintenance requirements of hydraulic cylinders))

This machine tool mainly consists of a bed body, spindle system, servo reciprocating part, servo feed part, electrical system, cooling and filtering device, lubrication system, protective cover, fixture, honing tool, etc

This machine tool body is made of welded steel profiles and undergoes multiple tempering to relieve stress, ensuring the removal of welding stress. It is processed using a large gantry machining machine and completed in one clamping operation. The machine tool has high strength and excellent geometric positioning accuracy. And it can ensure the long-term stability and high precision of the machine tool.

The spindle box is a key component of this machine tool, with all gears having a precision level of 6 and all bearings being imported high-precision bearings, ensuring high speed, high transmission ratio, and low noise performance of the transmission. At the same time, all components have been optimized through finite element force analysis and computer dynamic simulation, demonstrating high reliability. The spindle box is developed specifically for deep hole honing machines, which can achieve constant power honing of pipe fittings within the machining range. The sliding device of the spindle box drag plate can easily remove the spindle box and honing tool from the machined hole after one honing cycle, facilitate hole inspection and measurement, facilitate the replacement of oil stones and workpieces, keep the honing head in a safe state, and avoid scratching the workpiece. At the same time, for the same workpiece, it can ensure that the parameters of the starting and ending points of the stroke remain unchanged. For the next work cycle, there is no need to reset the parameters, which improves work efficiency.
 

The reciprocating system consists of a reciprocating motor, a reduction gearbox, active and passive sprocket boxes, and roller chains. The reciprocating power is 4.5KW, the reciprocating speed is 0-40 meters per minute, and the speed is adjustable. The system has a repeated positioning accuracy of 0.1mm. The chain tension has been adjusted before leaving the factory, and after working for a period of time, it needs to be regularly checked by adjusting the M30 nut at the tail of the spindle bed

Composed of servo motor, harmonic reducer, one tooth planetary acceleration, coupling, etc. Automatic stone compensation system, with a feed resolution of 0.001mm, ensuring the stability of machining dimensions

The control system is a self-developed honing control system by Liruite, with a 15 'color touch screen human-machine interaction interface. All electrical components are well-known brand products with a protection level of IP65 or above, reliable performance, and reserved interfaces for input and output, touch screen control operation interface, multilingual text display, used for input of processing parameters, processing monitoring, and manual control functions; Dynamically display the status of the honing process, and set machining parameters such as the honing head speed, reciprocating stroke speed, reciprocating stroke position, feed rate, and feed rate on the touch screen. Manual operation, machining monitoring, and fault alarm display of various movements of the honing machine can also be performed. The fault alarm is displayed on the touch screen fault alarm interface, which can quickly identify the fault point through fault indication and text display. The system has a manual and automatic switching function. The system has an automatic geometric accuracy repair function to ensure the consistency of honing workpiece dimensions.
