This machine tool can perform drilling, reaming, boring, tapping, scraping the end face, turning the end face, milling the plane, and cutting the spring clip groove on large cast iron parts, steel parts and other non-ferrous metal workpieces. The two vertical moving axes of the left and right main spindle boxes, as well as the linear moving axis of the worktable, are all equipped with British ball-grid digital display devices. Therefore, it is particularly suitable for processing long coaxial holes in frame-type parts.

1.This machine tool adopts a layout with two vertical columns, two horizontal axes, and a large central worktable with a wide lateral travel. The two columns and the left and right spindle boxes are symmetrically arranged along the center line of the worktable. The thermal symmetry performance of the entire machine is excellent. The relative displacement caused by the thermal deformation of the two boring axes is small, effectively improving the coaxial accuracy of the boring holes. The overall shape of the machine is regular and beautiful, and the operation is convenient. 

2. The main movements of the left and right main spindle boxes and the vertical feed all adopt hydraulic pre-selected speed change; during the speed change process, the main motor rotates at low speed in both forward and reverse directions to ensure smooth meshing of the gears. 

3. The left and right main shafts adopt a double-layer structure, equipped with detachable flat rotating discs and other accessories, expanding the processing scope of the machine tool. 

4. The vertical guide rails of the left and right main spindle boxes, the guide rails of the left and right slide seats, and the moving guide rails of the worktable all adopt TSF polytetrafluoroethylene coated guide rails. These guide rails have a low friction coefficient, which can reduce the wear of the guide rails, eliminate the crawling phenomenon at low speeds, and improve the stability and positioning accuracy of the operation. 

5. The machine is equipped with two longitudinal beds. The left and right columns are driven by a quick movement mechanism, enabling the sliding seat to achieve rapid longitudinal movement. This facilitates the operators' loading and unloading of the tool holders and their proximity to the workpiece. At the same time, it supports mechanical step feed, meeting the requirements for boring operations.
