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

What are the requirements for the runners of die-casting molds?

The runners of die-casting molds have corresponding requirements, so we need to understand these requirements as much as possible, which is of great help for us to use die-casting molds.

1. All molds should shorten the runner stroke as much as possible and reduce the cross-sectional area as much as possible on the premise of ensuring the forming quality. The cold slug hole is 1.5 times the diameter of the runner. All runners require cold slug holes, such as: below the mouth, The end of the runner, below the glue inlet of the fine nozzle, etc.

2. All fine nozzle molds, mold runners and nozzle hooks must be polished. It is necessary to ensure that the glue inlet is smooth, reduce the injection pressure and no residues are left on the product.https://ptjcnc.com

3. The flow channel section of the large nozzle mold should be round or up and down ellipse, that is, the height dimension is 0.5-1.0 larger than the width dimension and must be aligned before and after, and there should be no misalignment in polishing. In special circumstances, the unilateral flow path is required to be trapezoidal.

4. The inlet and nozzle positions should not be in the obvious appearance. The glue inlet point of the electroplating product should ensure the strength. The glue inlet point of the large nozzle and the product contact should be the knife edge surface with the smallest cross-sectional area to ensure that no residue remains after removal.

5. The position of the thimble or hook pin for diving into the glue must be at a certain distance from the glue inlet of the parting surface, which is about 1.5 times the diameter of the runner, in order to ensure the toughness of the dive inlet. The diving gate must be polished.

6. The injection point of the large nozzle of the gear die is at the bottom of the tooth surface. Use a Φ1.0 milling cutter to align the tip of one of the teeth with a depth of 0.5-0.6, a width of 1.2, and a depth of 1.5, AB plate inserts. When inlaid through-holes are to be proceassed together, if through-holes are not inlaid, it is necessary to use the centering rod to center repeatedly to ensure concentric accuracy. The barrel needle of the rear mold is inserted into the front mold, and a drill bit smaller than the processing hole diameter must be used to make it thicker to facilitate the copper electric discharge machining.
