CNC vertical lathe is one of the most widely used CNC machine tools at present. It is mainly used for cutting the inner and outer cylindrical surfaces of shaft parts or disk parts, the inner and outer conical surfaces of arbitrary cone angles, the complex rotary inner and outer curved surfaces, cylinders, and conical threads, etc., and can perform grooving and drilling. Holes, reaming, reaming and boring etc.

Features of CNC vertical lathe:
the
- This machine tool is designed and manufactured with high-grade cast iron and box-shaped structure. After proper annealing treatment, internal stress is eliminated, and the material is tough. In addition to the box-shaped structure design and high-rigidity body structure, the machine has sufficient rigidity and strength. , The whole machine exhibits the characteristics of heavy cutting resistance and high reproduction accuracy.
the - The base and the headstock are integrated box-shaped structure, which adopts thick rib wall and multi-layer rib wall design, which can effectively restrain thermal deformation, and can withstand static and dynamic distortion and deformation stress, ensuring high rigidity and high stability of the bed.
the - The column adopts a honeycomb symmetrical box structure, and the interior is designed with thick-walled ribs and round-hole ribs to eliminate internal stress, which can provide strong support for the slide table during heavy cutting, ensuring high rigidity and high-precision display of the bed .
the - High-precision, high-rigidity spindle head: This machine adopts FANUC high-horsepower spindle servo motor (power 15kw/18.5kw).
the - FAGNSK series bearings are selected for the spindle bearings. The axial and radial loads provided by the bearings can ensure heavy cutting for a long time, with excellent precision, stability, low friction, good heat dissipation and spindle support rigidity.
the - X/Z axis: FANUC AC servo motor and large-diameter ball screw (precision C3, adopting pre-tensioning method, which can eliminate thermal expansion and improve rigidity) direct drive, no cumulative error of belt drive, accurate repeatability and positioning accuracy , Supporting bearings adopt high-precision bevel ball bearings.
the - The X/Z axis adopts super-heavy-duty linear guide rails with high rigidity and low friction coefficient, which can realize high-speed feed, reduce guide rail wear, and extend machine tool accuracy. This type of linear slide rail has a small friction coefficient and high quick response, which can meet the requirements of high machining accuracy and realize high-load cutting.
the - Lubrication system: The automatic pressure-relief lubrication system of this machine supplies oil during collection, and the advanced pressure-relief intermittent oil supply system provides timely and appropriate oil supply for each lubrication point in a timing, quantitative, constant pressure, and individual manner. , to ensure that each lubricating position does get lubricating oil, so that the machine can operate for a long time without any worries.
the - Full-cover sheet metal: Under the strong requirements of environmental protection and safety considerations for operators, the design of sheet metal focuses on aesthetic appearance, environmental protection and ergonomics. The fully sealed sheet metal design prevents cutting fluid and cutting chips from splashing outside the machine tool, keeping the surroundings of the machine tool clean. In addition, there is a design for cutting fluid to flush the bed on both sides of the machine tool, so that cutting chips do not stay on the bed as much as possible.
the
The CNC vertical lathe uses the prepared processing program to automatically process the processed parts. We write the processing route, process parameters, tool trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of the program sheet On the control medium, it is then input into the CNC device of the CNC machine tool to control the machine tool to process the parts.
