CNC high-speed precision parts machining process CNC high-speed precision parts machining mainly refers to the use of digital information recorded on the media to control the machine tool so that it can automatically perform the specified machining tasks. Numerical control cnc machining aluminum can ensure that the product achieves extremely high machining accuracy and stable […]
The main characteristics of the linear and hard rails of the CNC machining center are as follows: 1. The advantages of hard rail: 1. It can withstand larger loads and is suitable for roughing machine tools with large tool volume and large feed. 2. Because of the large contact area of the guide rail, the […]
CNC lathe machining is a high-precision and high-efficiency machining method that uses digital information to control the displacement of parts and cutters by automatic machine tools. It is an effective way to solve the problems of aerospace products and parts with many varieties, small batches, complex shapes, and high precision, and to realize efficient automatic […]
Invar alloy-basic information definition Invar (Invar, also known as Invar, changed its name to a brand name), is a nickel-iron alloy with a composition of 36% nickel, 63.8% iron, and 0.2% carbon. Its coefficient of thermal expansion is extremely low and can Maintain a fixed length over a wide temperature range. Common name Invar alloy, […]
Common defects of cast iron parts include: pores, sand sticking, sand inclusion, sand hole, expansion sand, cold barrier, insufficient pouring, shrinkage porosity, shrinkage cavity, lack of meat, sarcoma, etc. Why are there always defects in the lost wax casting process? The gas does not escape in time before the molten metal is crusted, and thus […]
The feed motion of a CNC machining machine tool is the direct object of digital control. Regardless of point control or contour control, the final dimensional accuracy (accuracy) and contour accuracy of the workpiece are affected by the transmission accuracy and sensitivity of the feed motion. (Sensitivity) and stability (explanation: stability and stability; no change). […]
The weight and size range of cast aluminum parts are very wide. The lightest weight is only a few grams, the heaviest can reach 400 tons, the thinnest wall thickness is only 0.5 mm, the thickest can exceed 1 meter, and the length can be several millimeters to ten. A few meters can meet the […]
Repetitive production parts processed by CNC lathes: The preparation time of procedures using CNC grinders occupies a relatively high proportion. For example, process analysis preparation, programming, adjustment and trial cutting of the first part of the part, the total of these comprehensive man-hours is often dozens to hundreds of times the man-hours of a single […]
In the machining process of the CNC machining center, whether the selection of the positioning reference is reasonable determines the quality of the parts, and has a great influence on whether the dimensional accuracy and mutual position accuracy of the parts can be guaranteed and the machining sequence arrangement between the parts. When the workpiece […]
There are two types of cutting fluids used in CNC machining in Dongguan: one is oil-based cutting fluid and the other is water-based cutting fluid; The cutting fluid used in cnc machining is divided into four types: cutting oil, emulsion, semi-synthetic fluid, and synthetic fluid; for the above four cnc machining cutting fluids, You may […]
