Twin Spindle Tapping Machines

This is a precision thread-cutting machine that cuts threads using a high-precision carbide tap. The pitch of the thread is set up using changing gears in conjunction with a lead screw and nut. The gears of the feed train are manufactured to a high degree of precision and the feed is derived through a high-precision ball screw.

Advantages of the Heavy-Duty Tapping Machine

The machine offers a high production rate hence the cost per component becomes very low. It is designed in such a way that it can achieve max torque at low rpm for the tapping of M80X6 mm pitch and for M27X3 mm pitch. The machine provides torque at high rpm through a reduced gearbox and electric motor. The machine is suitable for tapping up to M80X6 mm pitch in a single pass which is not possible with an ordinary tapping machine. The automatic material feeding unit and automatic material unloading unit make the machine a completely automated tapping machine. The variable frequency drive unit of the machine (100) offers various cutting speeds for the operation.

Salient Features of the Machine:

a) A lead control mechanism that provides precise positive axial movement of the tap into the predrilled hole corresponding to the lead of the thread tap;

b) Automatic reversal of spindle at the end of tapping;

c) Safety arrangement to prevent tap damage due to overload.

Appropriate cutting speeds of tapping are established based on the material of the job to be cut, the material of the tap, and the cutting oil/tool lubrication provision.

The machine is designed and built for tapping operations ranging from dia. 27 mm x 3 mm pitch to dia. 80 mm x 6 mm pitch. Being a two-station machine, two spindles carry out thread cutting of two jobs simultaneously.
