2. Angle plate - Wikipedia

   en.wikipedia.org/wiki/Angle_plate

   An angle plate is a work holding device used as a fixture in metalworking. Angle plates are used to hold workpieces square to the table during marking out operations. Adjustable angle plates are also available for workpieces that need to be inclined, usually towards a milling cutter .

3. Parallel (engineering) - Wikipedia

   en.wikipedia.org/wiki/Parallel_(engineering)

   The most common use is to support work when it is in a vise or clamped to the machine bed. If a workpiece is too small to be machined in a vise without it being in contact with all three faces of the vice - parallels can be used either side to give clearance from the vise, and to give support from underneath to eliminate the workpiece being ...

4. Sine bar - Wikipedia

   en.wikipedia.org/wiki/Sine_bar

   Angles are measured using a sine bar with the help of gauge blocks and a dial gauge or a spirit level. The aim of a measurement is to measure the surface on which the dial gauge or spirit level is placed horizontally. For example, to measure the angle of a wedge, the wedge is placed on a horizontal table. The sine bar is placed over the ...

5. Rotary table - Wikipedia

   en.wikipedia.org/wiki/Rotary_table

   Rotary tables are most commonly mounted "flat", with the table rotating around a vertical axis, in the same plane as the cutter of a vertical milling machine.An alternate setup is to mount the rotary table on its end (or mount it "flat" on a 90° angle plate), so that it rotates about a horizontal axis.

6. Indexing head - Wikipedia

   en.wikipedia.org/wiki/Indexing_head

   Indexing heads are usually used on the tables of milling machines, but may be used on many other machine tools including drill presses, grinders, and boring machines. Common jobs for a dividing head include machining the flutes of a milling cutter , cutting the teeth of a gear , milling curved slots, or drilling a bolt hole circle around the ...

   Vertical milling machine. 1: milling cutter 2: spindle 3: top slide or overarm 4: column 5: table 6: Y-axis slide 7: knee 8: base. In the vertical milling machine the spindle axis is vertically oriented. Milling cutters are held in the spindle and rotate on its axis. The spindle can generally be lowered (or the table can be raised, giving the ...

8. Combination square - Wikipedia

   en.wikipedia.org/wiki/Combination_square

   Labelled diagram of the centre finder head with a circle as an example. The centre finder head can be used for: Marking lines through the centre of circular or square objects, such as dowels. Making multiple marks at different angles can be used to identify the point at the centre of the circle.

9. V-block - Wikipedia

   en.wikipedia.org/wiki/V-block

   V-Blocks are precision metalworking jigs typically used to hold round metal rods or pipes for performing drilling or milling operations. They consist of a rectangular steel or cast iron block with a 120 degree channel rotated 45-degrees from the sides, forming a V-shaped channel in the top. A small groove is cut in the bottom of the "V".
