The machine for holding the workpiece, rotating the cutter, and feeding it is known as the Milling Machine. Live Chat.
Holding your workpiece securely is essential to a successful project. In this post, I'll discuss seven proven methods to hold your workpiece so you can cut it accurately. I'll introduce each method, then summarize the pros and cons of each. Top Clamping. A common and simple way to hold down a piece is with slotted clamps.
Milling is the process of machining flat, curved, orMilling machines are basically classified as vertical or irregular surfaces by feeding the workpiece against a rotating horizontal. These machines are also classified as knee-type,
A Milling fixture is a work holding device which is firmly clamped to the table of the milling machine. It holds the work piece in correct position as the table movement carries it past the cutter or cutters. Essentials of Milling Fixtures: 1: Base: A heavy base is the most important element of a milling fixture.
Whether you are using workholding devices in milling machine operations, turning or drilling, or for processes such as boring and broaching, here are some general principles to follow: Find a workpiece orientation that maximizes the number of operations that can be performed per set up — especially if using tombstone fixtures.
The milling machine is a tool that is made to cut workpiece materials, which is operated by a program and managed by Computer Numerical Control (CNC) system. There are various parts of this machine, to know these parts you can see the description about 24 parts of the milling machine and their functions that are written below.

The plain milling machine vise is used for holding work which has parallel sides. The vise is bolted directly to the table using the T-slots in the machine table. The plain vise can be accompanied by a swivel base (Figure 2). ... Holding the workpiece off center puts unequal pressure on the vise jaws. This can cause the piece to loosen up.
Use of vices to hold workpieces. Apart from using clamps the most common way of holding a workpiece is by using a vice. In most cases the vice is bolted to the milling table. This is probably the most common set-up for either vertical or horizontal milling. It is usually faster to set-up a workpiece for machining using a vice than using clamps.
