What is the difference between the lathe of CY6140 and CY6140B?

What is the difference between CY6140 and CY6140B lathe? CY6140 is an ordinary horizontal lathe, this lathe has a wide range of process performance, suitable for general machinery manufacturing industry, single piece, small batch production workshop, tool manufacturing departments of various industries, machine and equipment repair departments and laboratories, it can be used for the inner and outer cylindrical, conical and other forms of ferrous metal, nonferrous metal, non-metallic workpieces. It can rough and finish the rotary surface of ferrous metal, non-ferrous metal, non-metallic workpiece, internal and external cylindrical, conical, and other forms of rough and finish machining; it can turn all kinds of commonly used metric, imperial, modulus, diameter section threads and multiple threads; and it can carry out the machining work such as drilling, reaming, and oil groove broaching.

CY6140B is also an ordinary lathe, the main technical parameters of the two models of lathes are not the same. Machine features:

1, castings are resin sand process manufacturing, aging and shaping, guideway by ultra-audio quenching treatment, the hardness reaches HRC55.

2, the spindle adopts a three-point support four bearings of high-precision design, high rigidity of the spindle, the absolute temperature rise of no more than 35 ℃. All pairs of gears and spline shafts in the head box are high-frequency quenching treatment, precision grinding and research and matching to ensure long life, low noise and low vibration.

3, fast feeding system can effectively improve the work efficiency, thread turning and tool walking without the need to change the hanging wheel, 24-speed variable speed, the maximum spindle speed of 1600rpm.

4, reliable safety devices, equipped with emergency brake button. Meanwhile, the feeding system is equipped with adjustable overload protection device.
