The processing process of water fountain of wind water sphere includes: blank selection, billet processing, ball rotary support hole processing, ball contour forming, grinding and polishing processing, repair support hole and so on.
Wind water ball can be made of marble, granite, jade, agate and crystal stone.The requirements for the production of wind water polo materials are higher than general stone carvings, columns and other special-shaped stone
products.First, it is required that the waste materials for the production of wind water polo balls and bases have no dominant and recessive cracks, and the material should be uniform in texture.To make wind water ball more
beautiful,sphere and base can choose the stone material of different color, design and color, but the property of material should be closer.
The purpose of billet processing is to remove the excess stone material on the outside surface of the ball, and make its contour as close to the shape of the ball as possible after leaving a reasonable processing allowance, so as to reduce the processing time on the equipment.The blank can be processed by manual method, or it can be roughed by circular saw and then trimmed manually.
Using a rotary table of three - dimensional or five - dimensional machine CNC rope saw can also be molded processing of spherical blanks.During the processing, the waste truck moves before and after, and the bead rope rises and falls synchronously.The bead rope moves from the top of the waste material to the bottom.After finishing the surface processing, the waste car rotates an Angle and enters the next surface processing;The scrap truck rotates 360° to form an angular sphere, and finally cuts off the bump.From the point of view of labor cost, CNC rope saw processing ball blank is not economical, because the effective cutting area of the ball is far less than usele ss cutting, so the consumption of bead rope is very large.
The processing method and requirements of the ball support hole are the same as those of the cylinder products.It should be noted that the opposite two support holes must pass through the same diameter of the ball.
At present, the method of molding and processing wind water ball is: the horizontal or vertical lathe, artificial or semi-automatic by imitation car made of processing, can also use CNC milling machine automatic molding processing.In the process of manual machining on the lathe, the operating line is required to follow the contour trajectory of the ball defined by the model, and the tool is always controlled to move along the trajectory of the grinding plate.When most of the surface of the sphere (in addition to the support boss or top hole) after grinding and polishing processing is completed, you can move the sphere, the boss will be removed or fill the top hole, using high friction coefficient material supporting other parts of the sphere, and then the two surface forming, grinding and polishing processing, until the completion of all surface processing of the sphere.
2.Processing of wind water ball base:
The processing difficulty of the base of the wind water ball is more difficult than that of the ball.The part of the base and the ball matching is the inner ball, and the difficulty is the matching gap and tolerance between the ball and the base.The processing process of the base includes material selection, base modeling processing, roughing of the inner sphere, forming of the inner sphere and flume, grinding and polishing of the inner sphere, water inlet hole processing,cleaning and inspection, etc.
The same as the material selection requirements of the sphere, as the base stone can not have cracks.For some large diameter and volume of wind water polo products, the base contour is generally made of natural rock surface modeling,and only simple chisel can shape the contour of the base.lf it is processing some small wind water ball products as family decorations, the base can also be made into a rotary body shape or water jet plate shape of polished products, then the need to use ordinary or CNC lathe and other equipment processing base contour.
The purpose of roughing the inner surface is to reduce the amount of stone needed to be removed when using CNC machining center, improve efficiency and reduce cost.The inner surface of the base can be roughed by using a circular saw machine with manual carving or installing a small diameter saw blade.The CNC machining center with more than three dimensional control function is the ideal equipment for forming the inner surface of the base. Ln order to grind the inner sphere of the base with the ball, the CNC machining center also needs to be equipped with a grinding power head that can install grinding and polishing abrasives.The inner sphere of the base can also be ground with simple equipment and manual method. Skilled workers can also process the inner sphere with high matching accuracy, but the production efficiency is lower than the mechanical equipment such as CNC machining center.
The inner surface of the water tank does not need grinding and polishing.After molding,the water inlet hole can be processed with a stone bit with an extended shank.lt should be noted that the inner wall of the tank and the wall of the water inlet hole must be washed clean with high pressure water before use, so as to prevent the debris falling in use from entering the matching gap between the ball and the base with the water flow, and wear the matching surface.
