Product Feature

The basic structure of the equipment is an integrated workbench base, the bed stands on the base, the workbench rotates, the beam moves vertically on the column, the slide seat moves horizontally along the beam, and the ram spindle moves vertically along the slide seat. The equipment can realize three axis linkage of X, Z and C.

The whole machine is composed of tool changer, column, worktable, base, hydraulic system, lubrication system, cutting cooling system, automatic tool change mechanism, full protection device, etc.

The beam is connected with the worm gear mechanism by the motor to drive the screw to rise and fall at any time. After the position is completed, the high pressure oil cylinder is used for positioning and locking to ensure the accuracy. X-axis guide rail adopts roller slide composite guide pair; The guide rail adopts Taiwan upper silver linear guide pair.

The processing accuracy and assembly accuracy of the grading positioning blocks on both sides of the column are high, and the distance is equal (the left and right grooves are processed together), so as to ensure the same lifting distance of the beam each time, and control the parallelism of the beam to the working surface. It will not affect the accuracy of the beam due to the different docking position of the tool rest, and indirectly affect the geometric accuracy and machining accuracy of the tool rest. At the same time, for the different height of the workpiece tool setting, programming has certain benefits, improve the efficiency of the use of machine tool.

The machine tool is mainly composed of working table, working table base,vertical column,crossbeam, turning milling tool post, cooling chip removal, whole machine semi-protection, cnc system, hydraulic system, electrical system and other main parts. The base of the working table is fixed on the foundation, and the vertical column is fixed on the base of the working table; The crossbeam moves up and down on the vertical column guideway; The tool post slide seat along the crossbeam guideway moves horizontally; The ram moves vertically along the sliding seat guide rail, and the rotating movement of the milling spindle; The main drive of the working table and the index feed movement of the table.

This machine tool is suitable for single piece and small batch production. Processing all kinds of medium and small disc type parts. The machine tool is suitable for high-speed steel and carbide cutters, rough, finishing processing black, non-ferrous metal and some non-metallic parts, can be inside and outside cylindrical surface, inside and outside conical surface, arc surface, metric and inch thread, boring, drilling and various complex shapes of rotary surface processing, can achieve constant

speed cutting.
