Product Description

DTM-B70 series turn-milling compound machining center is the third generation of orthogonal multifunctional turning-milling compound machining center designed based on the concept of standardization, modularization and serialization. It has the characteristics of high efficiency, high precision and high reliability. According to market requirements, it can be combined with different modules to form a turning and milling center with double spindles, double turrets, single or double steady rest, and a turning center without a tool magazine. Turning-based high-end CNC turning and milling machines. The maximum number of control axes of the machine tool is nine axes, and the maximum number of linkage axes is five axes (X, Y, Z, B, C). This series of machine tools is suitable for the turning of the outer circle, end face, thread, sink groove, and inner hole of various metal shaft parts, as well as the milling of planes and keyways. It can complete various curved surfaces that require multi-axis linkage to process. Efficient roughing and high-quality finishing can provide production-type turning and milling processing capabilities, especially for military, aviation, aerospace, ships, automobiles, railways and other industries with complex shapes and high processing precision parts.

Product Main features
1.Realize the functional integration of one machine and the compounding of multiple processes. It has multi-functional compound processing capabilities such as turning, boring, end milling, end milling, drilling, tapping, etc. It can quickly and high-quality complete the processing of complex workpieces, and its flexibility is especially suitable for the processing of complex, multi-variety and small-batch parts.
2.The combination of various functional components can realize the complete processing capability of six sides. The combination of functions such as B axis, milling axis, main and auxiliary spindles, steady rest, lower tool rest, tool setting instrument, and workpiece measurement will enable the machine tool to have strong compound processing capabilities and detection capabilities. The production capacity of the equipment not only greatly saves time and labor costs, but also reduces the area occupied by the equipment, and greatly improves the processing accuracy and equipment utilization.
3.The main shaft, sub-spindle and milling shaft of the machine tool are powerful, and can provide production lathes and milling processing capabilities.
4.Stationary frame with parking function.
5.High-precision guidance and closed-loop drive system ensure high transmission efficiency, good precision retention, fast and stable movement of the machine tool holder, and high positioning accuracy.
6.Machine tool cooling and heat balance system maximizes machining accuracy and stability. To prevent component deformation, the machine tool is equipped with a cooling device to minimize the generation of thermal displacement.
7.Double tool magazine system effectively expands the processing capacity of a single machine, especially the drilling and boring function;
8.The workpiece and the tool are as close as possible to the operator, which is convenient for observing the cutting, measuring the size and maintaining the tool;
9.The one-button self-cleaning system without dead angle can reduce the maintenance work intensity of the internal processing space of the machine tool and improve the protection life of the machine tool;
10.Automatic sliding door, multi-dimensional operation table, improve the pleasant operation of the machine tool.
