The depreciation period for fiber laser cutting machines is typically determined based on the nature of their use, the pace of technological advancement, and industry practices, generally ranging from 5 to 10 years.
Specifically, if an enterprise manages the machine as a fixed asset, it must refer to Article 60 of the *Regulations on the Implementation of the Enterprise Income Tax Law of the People's Republic of China*. This regulation stipulates a minimum depreciation period of 5 years for fixed assets such as appliances, tools, and furniture related to production and business operations; however, as high-precision, technology-intensive equipment, the actual depreciation period for a laser cutting machine may be shortened due to technological iteration or usage intensity.
From a technical standpoint, the lifespan of core components (such as the laser generator, cutting head, and CNC system) directly affects the overall depreciation. For instance, imported fiber lasers can have a lifespan exceeding 100,000 hours; based on 8 hours of daily operation and 250 working days per year, the theoretical service life exceeds 12 years. Conversely, lasers in some domestic low-to-mid-range equipment may last only 50,000 to 80,000 hours, resulting in a correspondingly shorter depreciation period of 5 to 7 years. Additionally, the need for regular replacement of consumables-such as cutting head lenses and nozzles-incurs high maintenance costs, which indirectly influences depreciation calculations.
Regarding application scenarios, equipment used in high-intensity, 24-hour continuous metal processing (such as automotive manufacturing or shipbuilding) experiences significantly faster wear and tear than equipment used in light processing (such as signage production), potentially leading to a depreciation period closer to 5–6 years. In contrast, equipment used for R&D or small-batch prototyping sees lower usage frequency, allowing for an extended depreciation period of 8–10 years.
In terms of industry standards, equipment from internationally renowned brands (such as TRUMPF or Han's Laser) is often estimated to have a depreciation period of 8–10 years due to mature technology and high stability. Some domestic brands, aiming to capture market share quickly, may shorten the depreciation period (e.g., to 5–7 years) to lower the customer's initial investment cost; however, it should be noted that the residual value rate may decrease due to technological obsolescence.
It is important to note that the determination of the depreciation period must also align with the enterprise's accounting policies. For example, enterprises using an accelerated depreciation method (such as the double-declining balance method) may record higher depreciation charges during the early stages of equipment use, thereby shortening the actual depreciation period; in contrast, enterprises using the straight-line method allocate costs over a fixed number of years.
