QF Qing Qing road cutting sewing machine sewing machine sewing machine vibration corrosion road clear, many economists believe, QF clear sewing machine oil prices, although it will elevate the level of output in various ways, but the effect and impact of rising oil prices compared with the asymmetry, that rising oil prices on output is greater than the negative impact of falling oil prices on the positive impact of road cutting output sewing machine clean. There are at least explain this asymmetry in two ways: First, that sticky prices, wages have asymmetry, the second is that the reaction of monetary policy asymmetry. 3, a reasonable balance of the whole design, not only conducive to job stability blade under gravity and thrust, but also conducive to the reasonable demands of labor-saving operation 4, forced cooling hair design, increased blade life. 5, in order to try to reduce the use of idle machines that improve energy efficiency, the design of the work gear and neutral body. 6, the inner shaft kit shock absorption, anti-corrosion, anti-jamming design. Rated power: 9KW Rated speed: 3200r / min kerf depth: 50mm slit width: 2.5mm kerf speed: 200m / h Weight: 55kg Dimensions: 1000 × 600 × 850mm
