Mass Finishing Processes -

Introduction

Mass finishing processes are used for low cost, fast work on relatively large number of parts at one time. In other words, a large number of parts can be finished simultaneously by a mass finishing process.

Objectives of

The main purpose of a mass finishing process is:

(i) To finish parts not one by one, but many at one time.

(ii) To remove scale from castings.

(iii) To remove the burrs left on the work by previous operations.

(iv) To eliminate tool marks left by machining.

(v) To remove flash left around die castings.

(vi) To remove sharp edges for safety in use and assembly.

(vii) To provide good finish, sometimes referred to as burnishing and to bring out natural colour of the material.

(viii) To prepare, by the above, parts for painting.
