Turret Tools

Turret Tools - On a turret, the workpieces are machined, (i) either from the bar stock, or un in the form of separate castings or forgings held in jaw chucks or on face plates. Typical tools for bar work include

(i) Box tools, and

(ii) Hollow mills (for reducing the diameter of the bars of stock to the required size).

(iii) Special designs of turning tools or turners are used extensively on flat turret lathes,

(iv)Forming tools are used when there is an irregular surface to be machined,

(v) Drills and reamers,

(vi) Dies, when the part must be threaded,

(vii) Cutting off tools for severing finished parts, and

(viii) Many tools of special design.

In general, cutting off and forming tools are mounted on a cross-slide between the turret and headstock, whereas box tools, hollow mills, dies, etc., arc carried in the turret. For chuck work, the turret tool equipment often includes tools such as:

(i) Drills

(ii) Boring bors

(iii) Reamers

(iv) Facing cutters

(v) Taps

(vi) Dies, etc

A box tool held on the turret is commonly used for turning operations, As a box tool operates on the unsupported end of the bar projecting from the chuck, it is equipped with some form of backrest opposite the turning tool for supporting the work; it usually encloses or surrounds the turned part to some extent, and, for that reason, is known as a box tool.
