Tapping and Threading Machines

Reversible Tapping Attachment With Robust Construction Offer Following Advantages :
• Usable on every vertical drilling machine or machines with rotating non-reversing spindles.
Right or left hand tapping without modification.
Complete protection against tap breakage ensured by an ultra-sensitive and smooth operating ball-clutch.
• Forward and reverse ball drive design transmits rotational power to the tap and disengages smoothly and silently.
• Axial float ensures smooth tapping and better thread profile.
• Cushioned drive elimnates the possibility of cross threadings during roughing and finishing taps and ensures gauge prefect thread.
• A planetary gear reversing mechanism transmits smooth positive reverse to the tap retraction and it retracts 75% more faster than it enters.
• Accurate depth control by means of its accurate neutral mechanism.
• Batch quantities or mass production of tapping can be achieved accurately by this attachment
• Having versatile application in every machine shop, it dispenses with laborious hand tapping and use of expensive machines.

We have set a benchmark in the industry for manufacturing and offering Hand Threading Machine. The offered machine is operated by electricity and is easy to use. It is used for the threading of pipe and is impeccable in performance.

Coventry Dieheads can be used on Turret lathes, CNC and automatic screw machines. The total system is noted for its ease and simplicity in setting, and for the accuracy of cut over a very wide range of thread variations. Automatic self-opening at the completion of each cut makes Coventry ideal for batch or continuous production work.

Product features

• Rugged - simple construction for reliability and long life
• Compactness - permitting use on machines with limited clearance
• Accurate Pitch - due to the guiding action of the non-cutting portion of the die
• Adjustability - providing fine regulation of finished diameter for 3a class threads
• Clean and smooth threads - as the dies have cutting angles suited to the material being used
• RH and LH thread - by only changing chasers
• Parallel threads - due to the very efficient support of the dies in the diehead
• Minimum downtime - for change of thread size, important for production economy on short to medium batch runs

Advantages of Coventry Chasers

Coventry chasers are designed so that cutting takes place at the chamfer and the first full tooth. The other teeth are above centre height, so they act as a nut, ensuring accurate pitch.

Chaser features:

• Precision ground threads
• Lip types to suit various materials
• Four standard chamfer angles: 15, 20, 33 and 45 degrees
• Coventry Dies sorted by Diehead size : 1/4" (6mm) | 5/16" (8mm) | 3/8" (10mm) | 1/2" (12mm) 3/4" (20mm) | 1" (25mm) | 1,1/4" | 1,1/2" | 2" | 2,1/2"

DESCRIPTION :

Tap #10 to 1/2" (M3 - M12) threads

Quick loading and unloading

Adjustable clamping range

Good stability, high precision

FEATURES :
