Many wonder whether a dispensing machine will be noisy in the workshop \u2014 the national standard answers clearly. GB\/T 26799-2011 'General Specifications for Dispensing Machines' requires that noise under no-load operation not exceed 70 dB. The 2024 group standard for dual-five-axis high-precision smart dispensing machines (T\/CASME) likewise caps no-load noise at 70 dB. What does 70 dB mean? Roughly normal speech or a busy street background \u2014 it will not harm operators' hearing or health.<\/h2>\n\n\n\n

2. Real Workshop Noise Levels<\/p>\n\n\n\n

\"\u58f0\u7ea7\u8ba1\uff0c\u7a7a\u8f7d\u8fd0\u884c\u65f6\u6240\u4ea7\u751f\u7684\u566a\u58f0\u5c0f\u4e8e70\u5206\u8d1d\uff0c\u300aGB\/T<\/figure>\n\n\n\n

The standard covers no-load noise; loaded noise in production runs slightly higher<\/h2>\n\n\n\n

. A single dispensing machine in a real workshop measures about 76-80 dB; with proper layout, vibration isolation and sound insulation, boundary noise can drop to 55-60 dB, meeting the daytime 65 dB limit for Class 3 areas under the 'Industrial Enterprise Boundary Environmental Noise Emission Standard'. In other words, one dispensing machine alone is not loud, but with several machines running plus<\/strong>air pumps and punch presses, noise stacks up and needs treatment.<\/strong>3. Where the Noise Comes From<\/p>\n\n\n\n

Dispensing machine noise has three main sources.<\/h2>\n\n\n\n

First, the motion system<\/p>\n\n\n\n

: servo motors drive screws moving the XYZ axes at high speed; motor rotation and screw transmission both generate<\/strong>mechanical noise\u2014 the faster, the louder.<\/strong>Second, the pneumatic system<\/p>\n\n\n\n

: dispensing relies on compressed<\/strong>air drive; solenoid valve switching, air pump operation and exhaust all produce airflow noise.<\/strong>Third, structural resonance<\/p>\n\n\n\n

: frame, worktable and sheet-metal housing may buzz in resonance during high-speed motion \u2014 especially obvious on poorly assembled small-shop machines.<\/strong>4. Noise Reduction Methods<\/p>\n\n\n\n

Noise reduction can start from several angles.<\/h2>\n\n\n\n

: the machine base must be level and solid; add<\/strong>damping padsto reduce structure-borne transmission; air pumps can be placed outside the workshop or fitted with silencers.<\/strong>Workshop level<\/p>\n\n\n\n

Compact structure and disciplined assembly keep no-load noise within the national standard. When purchasing, confirm noise specs with the vendor and, if necessary, test on site with a sound-level meter before ordering.<\/p>\n\n\n\n

6. Summary<\/h2>\n\n\n\n

The national standard GB\/T 26799 caps dispensing machine no-load noise at 70 dB; real loaded noise is about 76-80 dB. Noise comes from the motion system, pneumatic system and structural resonance; it can be effectively reduced bychoosing compliant products, adding damping pads, sensible layout and regular lubrication<\/strong>\/ How to Maintain a Dispensing Machine?<\/p>\n\n\n\n
