Large double head gantry drill

Large double head gantry drill

The joint surfaces between the headstock of the large double-head gantry drilling machine and the bed, tailstock, pallet, etc. are manually scraped and ground. The entire machine is tested using a laser interferometer, which meets the positioning accuracy of the Z-axis and X-axis and the repeatability accuracy. , backlash and lathe stability. The lathe uses high-strength cast iron, with special copper and chromium materials added. The width of the bed guide rail is 400mm, and the quenching scale of the bed guide rail reaches 4mm, which improves the stability of the lathe.

The large double-head gantry drilling machine has the following characteristics:

1. Good processing accuracy and stable processing quality.

2. It can perform multi-coordinate linkage and process parts with complex shapes.

3. When the processed parts change, only the CNC program is changed to save production time.

4. The lathe itself has good precision and high rigidity. You can choose a lathe with high processing capacity and good productivity.

5. The lathe has a good degree of automation and can reduce labor intensity.

Large double-head gantry drilling machines should not cut printed circuits at will. Some maintenance personnel have certain experience in repairing home appliances and are used to checking for broken wires. However, most of the circuit boards on CNC equipment are double-sided metal orifice boards or multi-layer perforated boards. The printed circuits are thin and dense. Once cut, it is difficult to weld and the lines are cut. Sometimes it is easy to cut off adjacent lines, and at some points, when cutting a certain line, it cannot be separated from the line, and it is necessary to cut several lines at the same time.

The processing accuracy of large double-head gantry drilling machines can generally reach 0.05-0.1MM. Double-head CNC drilling machines are controlled in the form of digital signals. Every time the CNC device outputs a pulse signal, the moving parts of the lathe move by a pulse equivalent (usually 0.001MM ), and the backlash of the lathe feed transmission chain and the average error of the screw pitch can be compensated by the CNC device. Therefore, the positioning accuracy of the double-head CNC drilling machine is relatively high.
