China took the lead in effectively controlling the epidemic in 2020, and the economy has recovered rapidly since the second half of the year, with full-year GDP growth of 2.3% year-over-year. Building on this, China's economy continues to grow strongly in 2021, with GDP growth of 18.3% year-on-year in the first quarter and 10.3% over the first quarter of 2019.

The growth of the domestic economy has driven the recovery and growth of the market demand for machine tools. From January to March 2021, the machine tool industry continued the restorative growth trend since the second half of 2020, with significant growth in all major economic indicators compared to the same period of the previous year and 2019. According to China Customs data, the first quarter of 2021 showed an overall significant growth in the import and export of machine tools, with total imports and exports increasing by 30.5% year-on-year and 9.5% compared to the first quarter of 2019.

January-March 2021, metalworking machine tools new orders increased by 90.1% year-on-year; on-hand orders increased by 28.1% year-on-year. Among them, new orders for metal cutting machine tools increased by 111.5% year-on-year, and orders on hand increased by 25.6% year-on-year; new orders for metal forming machine tools increased by 53.7% year-on-year, and orders on hand increased by 34.6% year-on-year. Compared with the same period in 2019, new orders for metalworking machine tools grew by 62.7%, with new orders for metal cutting machine tools up 74.6% and new orders for metal forming machine tools up 31.7%. Orders on hand grew on a similar trend.

Online technical support is available through social software for most of our products, such as CNC lathes. Another way is to pre-install modules for remote monitoring technical support in the equipment, so that remote technical support can be provided via the Internet in the event of a failure, such as rotary transfer machine. For most of our machines we send spare parts for some of the easily breakable parts with the machine.

    The dual spindle CNC lathe is developed and designed for certain parts that need to be machined at both ends. Both twin spindles can clamp the bar stock. By having one of the spindles clamp the bar stock, the other spindle can finish machining one of the ends of the bar stock, and afterwards the other spindle will clamp the bar stock and finish machining the other end of the bar stock. This allows the entire process of a part to be completed on a single machine. The productivity of this machine is much greater than two lathes, and the labor cost and equipment cost are lower than two lathes.

Our machine module: GT260V

1.Maintenance related person

    a) Operators are responsible for the use, maintenance and basic upkeep of the equipment.

    b) Equipment maintenance personnel are responsible for the repair and necessary maintenance of equipment.

2.Basic requirements for the use of CNC equipment

    a) CNC equipment requires avoiding places with humidity, excessive dust and corrosive gases.

    b) Avoid direct sunlight and other thermal radiation, and keep precision CNC equipment away from equipment with high vibration, such as punching machines and forging equipment.

    c) The operating temperature of the equipment should be controlled between 15 degrees and 35 degrees. The temperature during precision machining should be controlled at about 20 degrees, with strict control of temperature fluctuations.

    d) To avoid large power supply fluctuations (±10%) and possible instantaneous interference signals and other effects, CNC equipment generally use a dedicated line power supply (such as from the low-voltage distribution room to divide a separate way for CNC machine tools), additional voltage regulators, etc., can educe the impact of power supply quality and electrical interference.

3.Daily machining accuracy maintenance

    a) After the machine is turned on, it must be preheated for about 10 minutes before processing; the preheating time should be extended for machines that are not used for a long time.

    b) Checking that the oil circuit is clear.

    c) Keep the machine dry and clean.

4.Daily maintenance

    a) Daily cleaning of machine dust and chips: including machine control panel, spindle taper hole, tool carriage, tool magazine tool arm and tool bin, turret, flexible hose inside the machine, etc.

    b) Checking the level of lubricating oil to ensure machine lubrication.

    c) Check whether the coolant in the coolant tank is sufficient, add in time when the coolant is not sufficient.

    d) Check if the air pressure is normal.

    e) Check all signal lights, alarm warning lights are normal.

    f) Checking the oil pressure unit tube for leaks.

    g) Cleaning of the machine after daily work.

    h) Maintain a clean environment around the machine.

5.Weekly Maintenance

    a) Cleaning of air screens of heat exchangers, cooling pumps, lube oil pump screens.

    b) Check if the tool bolt is loose and the tool handle is clean.

    c) Check if the mechanical origin is offset.

    d) If there is an oil cooler check the oil cooler oil, such as below the scale line please refill the oil cooler oil in time.

    e) Clean the impurities and water in the compressed gas, check the oil volume in the oil mist separator, check whether the solenoid valve of each circuit is working normally, check the sealing in the pneumatic system, because the condition of the air circuit system directly affects the knife change and lubrication system.

    f) Prevent dust and dirt from entering the inside of the CNC device. In the air of the machine room will generally have oil mist, dust and even metal powder, once they fall on the circuit board or electronic devices within the CNC system, it is easy to cause a drop in insulation resistance between the elements, and even lead to damage to components and circuit boards.
