Assembly benchmark refers to the accuracy used to determine the position of parts in components or products during assembly. Measurement benchmark refers to the standard used to measure the (DE) size and position of the machined surface during the inspection of (SH ì) parts (L í ng). Positioning benchmark refers to the benchmark used to locate the workpiece in the machine tool or fixture during processing.
Reference electrode must be used to control. 3. Ion deposition oxide coloring method: stainless steel workpiece is placed in a vacuum coating machine for vacuum evaporation plating, such as titanium plated watch shell and watch belt, which are generally golden yellow. This method is suitable for mass product processing, because of large investment, high cost and small batch products (P ǐ n) Not cost-effective, at present.
Among them, the CNC milling machine with tool magazine is also called machining center. The machining center is often divided into vertical machining center and horizontal machining center according to the state of the spindle in space. The spindle of the machining center in the vertical state in space is called vertical machining (zh ō NG) center, the spindle (zh ò U) is in a horizontal state in space, which is called horizontal machining center, and the spindle can be converted vertically and horizontally, which is called vertical horizontal (w ò) plus (Ji) ā) Machining center or five sided machining center, also known as composite machining center.

The relative humidity is 45% ± 5%. In precision machining, higher requirements are put forward for the machining accuracy and accuracy stability of the workpiece. According to relevant data statistics, in precision machining, the machining error caused by thermal deformation accounts for 40%-70% of the total machining error. Therefore, in high precision machining, in order to (Li ǎ o) To avoid the expansion and contraction of the workpiece due to temperature changes, the reference temperature of the environment is generally strictly stipulated, and the deviation range of temperature changes is formulated. Constant temperature processing of 20 ℃± 0.1 ℃ and 20 ± 0.01 ℃ has appeared.
As the torque of the spindle decreases at low speed, special attention should be paid to the selection of cutting parameters at this time. Anhui auto parts precision CNC machining is customized.
2. The tool in the program table and the tool in the actual program are misspelled. 6. During manual rapid feed, the Z axis can be raised to the workpiece and moved first, and the mechanical aluminum alloy parts must be customized. 4. The program must be carried out one by one. 3. Measure the actual machining depth on the workpiece, and clearly (D ì) indicate the length and length of the blade on the program table (generally, the length of the tool holder is 2-3mm higher than the workpiece) and the working and blade length is 0.5 -1.0mm). 1 Be sure to pay attention to the position of (Y ì) depth z axis tool setting (lower surface, upper surface, analysis surface, etc.).
