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, the starting and ending parameters of the stroke can be guaranteed to remain unchanged, and 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 oilstone compensation system, with a feed resolution of 0.001mm, ensures 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.The electrical control cabinet can be vertically independent or placed under the bed

The device includes lubrication system, magnetic filtration system, etc. Magnetic separator for secondary filtration, with a filtration capacity greater than 50L/min, an oil tank capacity of 500L, adjustable temperature, and an independent chip collection box for easy removal of filtered waste. Depending on the situation, a paper tape filter can be selected to filter non-magnetic substances and an oil cooler can be used to maintain constant temperature operation of the honing oil. The specific supply configuration is subject to the equipment list in item eight.

Design specialized fixtures with adjustable fixture range and manual loading and unloading method. The fixture positioning is reliable, easy to adjust, and the loading and unloading are convenient and fast. Pneumatic automatic fixtures and automatic loading and unloading systems can be optionally equipped, and a honing production line can be customized according to customer requirements. The specific supply configuration is subject to the equipment list in item eight.

At present, honing machines are mainly classified into two types: vertical and horizontal. Vertical machines are further divided into multi station and single station types. In addition, vertical machines are also divided into hinge honing machines and expansion honing machines

The horizontal honing machine has a spindle that moves horizontally. The advantage of this honing machine is that it can process workpieces with ultra long strokes, up to a maximum of 20 meters. The disadvantage is that the horizontal honing machine has a lack of machining accuracy due to the spindle's horizontal movement, and the honing rod is under its own gravity, making it unable to process workpieces with ultra-high precision. On the other hand, the vertical honing machine can process workpieces with ultra-high precision, and the maximum taper and ellipse after honing can reach 0.001mm. However, due to limitations, the vertical honing machine cannot process workpieces that are too long. Processing workpieces over 3 meters requires high floor height in the factory building.

Hydraulic honing machine is mainly used for machining hydraulic cylinder liners. In the machining of cylinder liners, the surface of the cylinder liner can have uniform and small diamond patterns, also known as honing patterns. The formation of honing patterns can create a layer of oil film on the inner wall surface of the cylinder liner, preventing dry grinding. This greatly increases the life of the cylinder sealing ring and can also reduce and alleviate the crawling and shaking of the cylinder when it is low
