Basic knowledge of Longmen planer milling machine must be understood：

Longmen planer milling machine has a double-column beam lifting gantry structure. The machine tool consists of a bed, a workbench, a gantry frame, a beam, a carriage, a headstock, a ram, a milling head and electrical appliances. The main parts are composed of.

The workbench moves vertically along the guide rail of the bed (X-axis), the carriage moves laterally along the guide rail of the beam (Y-axis), the beam moves vertically along the vertical guide rail of the left and right columns (W-axis), and the square ram with the headstock moves vertically in the carriage (Z-axis).The main drive is transmitted from the main drive shaft in the square ram to each milling head through the spline pair.

The main structural characteristics of the machine tool

The basic parts of the bed, workbench, column, beam, etc. are all made of resin sand, high-strength HT300 cast iron, and age-treated. The design structure is reasonable, the casting and processing technology are good, and it has high stiffness, flexibility and precision stability.The gantry frame is composed of left and right columns, beams, and beds. The lower end of the column is firmly connected to the bed, and the upper end of the column is tightly connected to the beam to form a high-stiffness gantry frame structure.

The Longmen planer milling machine adopts a low-noise linear rolling guide rail with a cage, which can withstand loads in several directions, with high stiffness, high carrying capacity, dynamic stiffness and high motion accuracy.The friction control coefficient is small, which is convenient for lubrication.The balance of the headstock and the balance of the beam are hydraulically balanced.

The Longmen planer milling machine is equipped with an all-digital cnc system, a DC spindle motor for the main drive, an AC AC servo motor for each axis drive, and a corresponding speed regulating device and drive device.

According to the user's processing needs, it can be equipped with various quick-change accessory heads, and the machining processes such as boring, milling, drilling, and hole-cutting of the five inner and outer surfaces can be completed under one-time clamping of the workpiece.The control of the CNC system can realize any three-axis linkage and realize contour milling.The beam and ram of the machine tool are all made of high-precision ball screws, which are frictionless, have high transmission efficiency, have large bearing capacity in the direction of movement, and maintain high-precision transmission at high speeds, with long life and durability.Longmen planer milling is a newly developed product of our company. It absorbs the structural characteristics of the machine tool, adopts the process of manufacturing, machine tool performance, reliable structure, simple operation and easy maintenance. It is widely used in the machining industry for heavy-duty black and non-ferrous metal plane, bevel and concave-convex surface milling, with a performance price ratio.
