ZSK2309A three-coordinate heavy-duty compound CNC deep hole drilling machine

This machine tool is the first set of three-coordinate CNC heavy-duty composite deep hole drilling machine in China, with the characteristics of long stroke, large drilling depth and heavy weight. This machine tool is controlled by a CNC system and can be used to process workpieces with coordinate hole distribution. The X-axis drives the tool, the column system moves horizontally, the Y-axis drives the tool system to move up and down, and the Z1 and Z axes drive the tool to move longitudinally. This machine tool includes both BTA deep hole drilling (internal chip removal) and gun drilling (external chip removal). Workpieces with coordinate hole distribution can be processed. Through one drilling, the processing accuracy and surface roughness that generally require drilling, expansion and reaming processes can be achieved.
The main components and structures of this machine tool:
1. Bed
The X-axis is driven by a servo motor, driven by a ball screw pair, guided by a hydrostatic guide rail, and the hydrostatic guide rail pair carriage is partially inlaid with wear-resistant cast tin bronze plates. The two sets of bed bodies are arranged in parallel, and each set of bed bodies is equipped with a servo drive system, which can realize dual-drive and dual-action, synchronous control.
2. Drill rod box
The gun drill rod box is a single spindle structure, driven by the spindle motor, driven by synchronous belt and pulley, and has infinite speed regulation.
The BTA drill rod box is a single spindle structure, driven by the spindle motor, driven by the reducer through synchronous belt and pulley, and has infinite speed regulation.
3. Column part
The column consists of a main column and an auxiliary column. Both columns are equipped with a servo drive system, which can realize dual drive and dual motion, synchronous control.
4. Gun drill guide frame, BTA oil feeder
The gun drill guide frame is used for gun drill bit guidance and gun drill rod support.
The BTA oil feeder is used for BTA drill bit guidance and BTA drill rod support.
