Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

The use of micro-lubrication helps reduce operating costs

In deep hole machining, the traditional lubrication method is mainly based on pouring cutting fluid and cutting oil lubrication. This method has a great impact on the processing environment, waste liquid treatment, and operator health. Therefore, this method is not sustainable. The traditional method not only greatly affects the production enterprise environment, but also increases manufacturing costs. In many developed areas, micro-lubrication technology has been widely used in metal cutting.

When cutting, apply enough lubrication between the cutting tool and the workpiece, and continue to supply a small amount of oil, which can meet the lubrication requirements without wasting lubricant. Such lubrication technology brings many benefits to enterprises, such as cost reduction, improvement of processing environment, improvement of processing efficiency, and improvement of surface quality of processed parts. <br /> In the domestic market, micro-lubrication technology has also been widely used in the manufacturing process of auto parts, such as: crankshaft, connecting rod, box cover processing. The unique advantage of micro-lubrication is that it uses advanced atomization technology to obtain micron-level atomized particles, which are transported to the cutting point through spindles, drills, milling tools, taps and other equipment with internal cooling channels. Oil consumption is measured in ml/h (ml per hour), which greatly reduces processing and maintenance costs. Compared with the traditional processing lubrication method, it has obvious advantages, mainly because the oil mist can be micron level and has good permeability, so that there is good lubrication between the chips and the processing tools.

The advantages of trace lubrication are as follows:

(1) The oil mist can penetrate into the friction point and play a good lubrication effect;
(2) In deep hole machining, the compressed air flow rate can take away the cutting heat, and a large amount of cutting heat is taken away by the chips.
(3) The oil consumption is low, and the cutting friction points are always lubricated with an appropriate amount of reliable lubricating oil;
(4) The product is small in size, low in gas source consumption, and simple in operation;
(5) Reduce machine tool operation and maintenance costs and machine tool manufacturing costs; As the impact of cutting fluids on the environment has become increasingly prominent, the requirements for energy conservation and environmental protection are rising day by day. It is especially important to choose a suitable lubrication method. Minimal lubrication can help companies reduce operations cost. <br />
