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 relationship between cost reduction and MQL adoption

The advantages of the micro-oil-air lubrication technology itself:
1) Protect the environment: use plant-based synthetic lubricants, no waste cutting oil and waste liquid are produced, and the environment will not be polluted.
(2) Clean operating environment: Because MQL lubrication technology uses very little oil, it is a full-consumption lubrication, and it is very easy to clean the machine tool and factory environment.
3) Reduce processing cost: MQL lubrication technology is a lubricating oil consumption lubrication technology, so there is no waste liquid treatment cost. Fully save the power consumption of the cooling pump when the cutting fluid is cooled.

According to Alexander Stoll, a powertrain expert at Ford Motor Company in the United States, Ford spends every year on cutting fluid and filtration, daily protective treatment, waste disposal and energy consumption (chips must be cleaned and dried before recycling), as well as related health and safety aspects. The cost amounts to several million dollars. The company’s cutting fluid cost accounts for about 10% to 20% of the processing cost of each workpiece. Therefore, Ford has fully promoted the application of MQL technology, which has brought substantial and satisfactory economic benefits. <At present, MQL micro-lubrication technology has been used in domestic auto parts manufacturing equipment, such as crankshaft oil hole special machine, balancing machine, main journal cylindrical car, connecting rod and gear machine tool, etc. While the micro-lubrication technology is generally recognized by machine tool manufacturers and end users, it is also facing the problem of how to make the micro-lubrication technology fully play its role and improve processing efficiency. It is necessary to discuss the machine tool design, processing technology, lubrication mechanism, etc. In the case of the same cutting conditions, the idea of ​​using micro-lubrication technology to reduce processing costs is to optimize the processing route:

(1) Processing program and processing parameters: cutting tool path, feed, depth of cut, cutting speed.
(2) Cutting tools: geometry, materials, coating technology.
(3) Clamping system: clamping method and efficiency, clamping position, clamping accuracy, clamping force.
(4)&nbsp;&nbsp;&nbsp; Material being processed: rough state, material characteristics.
(5)&nbsp;&nbsp;&nbsp; Machine tool: machine speed.
Processing any workpiece requires a comprehensive consideration of how to reduce processing costs. Therefore, according to the method of optimizing the route of the processing technology, start with the easy implementation, according to the order of processing procedures and processing parameters, cutting tools, clamping systems, processed materials, and machine tools Adjust and optimize.
