We have in-house servo control automate drilling machine with higher speed & superior accuracy.
Machine is designed with Double Spindle Head which gives high production rate at the same platform with single operator, single motor, single coolant pump and double the production then in single spindle.
Drilling is the process of cutting holes in a solid material using a rotating cutting tool. The indentation is a starting point for the drilling of the hole. Drilling is a cutting process of material in which a drill bit is used to cut or enlarge a hole in a solid material.

1. The hole
The three most basic considerations for drilling a hole are:
2. Hole type and required precision affect tool choice. Drilling can be affected by irregular or angled entry/exit surfaces and by cross holes.

The speeds and feeds recommended for use with micro drills have been calculated to give good tool life combined with maximum productivity. The speeds and feeds given provide a good starting point; each application may require adjustments to speeds and feeds to achieve optimum results.
Coolant pressure is a key factor in micro drilling. Inadequate coolant pressure or volume can lead to premature tool failure. We strongly recommend use of high coolant pressures. The typical pressure recommended should be between 40-70 bar.
