JB/T2322.1--2002
This standard is formulated based on the structural characteristics and use requirements of horizontal lathe products. It is a performance test method standard that specifies and supplements standards such as GB/T9061-1988 "General Technical Conditions for Metal Cutting Machine Tools". This standard is proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Technical Committee for Standardization of Metal Cutting Machine Tools. The responsible drafting unit of this standard: Shenyang Lathe Research Institute. The main drafters of this standard: Teng Libo, Wang Fuyuan, Wu Zeyong, Zhang Liandi, Wang Xinghai. m

The measurement method of the noise pressure level of the machine tool during idling and loaded operation shall comply with the provisions of GB/T16769 and shall meet the requirements of this standard. 5.1.1 Noise pressure level test during idling
5.1.1.1 Test conditions
Before the test, the machine tool shall idling at medium speed for 30 minutes:
The chuck shall be installed during the test:
The spindle shall be tested step by step in forward and reverse rotation. During the test, the slide box shall be fed longitudinally, and the feed amount is 0.0005D, mm/r. Note: D is the maximum workpiece rotation diameter on the bed. 5.1.1.2 Test method
The test shall be conducted in accordance with the provisions of GB/T16769, and the size of the measurement environment and the installation position of the machine tool shall be drawn in proportion, as well as the size and shape of the reflective objects around the machine tool: and the material properties of the ground, walls, ceiling, etc. shall be described. Measuring points and test requirements:
a) The microphone is 1500mm above the ground. The positions of the plane measuring points are shown in Figure 2. In addition to these measuring points, any position that is considered to have particularly high noise shall be declared as an auxiliary measuring point and the position of the point shall be marked. When the maximum workpiece length of the machine tool is greater than or equal to 3000mm, the measuring points may be arranged only along the periphery of the spindle box and the slide box. b) The measurement should be carried out step by step at each speed of the spindle in both forward and reverse rotation. The sound quality (such as the presence or absence of noise, impact sound, etc.) should be noted when recording.
c) The difference between the actual measured value of the machine tool noise sound pressure level and the background noise sound pressure level should be greater than [OdB(A). When the background noise is 6dB(A)~10dB(A) lower than the machine tool working noise, the noise sound pressure level value should be corrected according to GB/T16769. d) New products or machine tools with improved structures can be subjected to spectrum analysis. 5.1.2 Load operation noise sound pressure level test
5.1.2.1 Test conditions
a) The cutting load should generally comply with the following provisions: Accurate measuring point position
D, ≤500mm It should be carried out under the condition of 50% of the maximum cutting power: Operator position
500mm
