machining
is much more expensive for high volumes

Machining is necessary where tight tolerances on dimensions and off-site
fabrication
finishes are required.Machining is the broad term used to describe removal of material from a workpiece, it covers several processes, which we usually divide into the following categories: Cutting, generally involving single-point or off-site
fabrication
multipoint cutting tools, each with a clearly defined geometry

It is important to view off-site

The traditional
machining
includes primers on turning, milling, drilling, and grinding.Most
machining
operations can be divided into those that remove
metal
from an item, off-site
fabrication
and those that form
metal
in an item.As a commercial venture,
machining
is generally performed in a machine shop, which consists of one or more workrooms containing major machine tools

Although a off-site

machine shop can be a stand alone operation, many businesses maintain internal machine shops which support specialized needs of the business
