Multi Drill / Tapping Heads
Subrto offer multi drilling / Tapping head as per requirement of drilling configuration drill sizes, component material and basic machine capacity. The power and rotary motion of mother machine spindle is transmitted to auxiliary spindles through gears. Minimum two spindles to twelve spindles are possible in an attachment. The specification of different model of multispindle drill heads and theirs capacities are given below.-
Advantages of Multi drill / heads
- Reducing cutting time as number of drill made at a time
- Reducing manufacturing cost per Piece
- Saving man power as well as machines.
- Saving loading, unloading and handling time.
- Repeting accuracies of drill with respect to centre to centre distance.
- Reducing wear and tear of machine per hole, as number of hole is made in one setting.
- Main body is in aluminium alloy for weight reduction, machined on CNC Machine As per design configuration.
- Auxiliary spindles are houses in steel spindle housing which are in turn fixed in accurately bored Locations.
- Hardened and ground gears give prolonged life and less noise.
- Special combined needle Roller, Thrust bearing used in spindle module to take care of redial and Axial thrust.
- Direction of rotation and speed of auxiliary spindles is same as that of motor machine.
- Quick mounting of multi-drill on the mother machine.
- Oil / grease is provided as per the requirement. Non contact type sealing is provided for grease lubrication

Subrto Multiheads are precision- built to provide continuous trouble free service when used properly for the work; they have been designed to do. They merit the same care and attention as any precision tool. Ensure Precautions while using the machines
- Ensure proper fixing of attachment on mother machine; align auxiliary spindles with respect to Fixture and drilling jig plate hole.
- Any misalignment may create problems in getting desired result on the component.
- This is very important to selecting proper speed and feeds.
- Drill should be properly ground for better result.
- Any unevenly ground tool will not cut the material properly and geometry on components will get Affected, there are advices to get better result use drill point grinder for drill ground.
