Metalworking cutting tools include bandsaws, broaches, drills, fly cutters, and reamers. They can be operated manually or by computer control, and perform contouring, drilling, and deburring cuts. Bandsaws can make straight, angled, or curved cuts, while broaches use serrated tips for roughing, semi-finishing, and finishing cuts. Pillar drills and radial arm drills are common, and fly cutters are used for internal drilling or precise external cuts. Reamers drill holes in metal, with cutting edges located on the tip or along the length of the tool.
Cutting tools that are often used for metalworking include bandsaws, broaches, and drills. Other types of machining tools might include fly cutters and reamers. While some cutting tools require some type of human interaction to perform a function, others may be completely computer controlled. Milling tools may be small enough to be bench or floor mounted, but they could also take up a large amount of space within a room. Cutting tools generally perform contouring, drilling and deburring cuts along with possible surface planing.
While band saws are commonly associated with woodworking, metal shops also employ them. The machine takes its name from the circular metal blade that cuts by rotating around two or three wheels. These saws can be used in horizontal or vertical position. The metal being cut could be placed in a vise with the saw blade descending onto the material, or the blade housing could be stationary, requiring the metal to be pushed towards the blade. Bandsaws typically make straight cuts, but materials can be rotated around the blade for angled or curved cuts.
Broaches generally use serrated tips that remove metallic materials. The bits might look similar to drill bits, with sharp edges around the bit that run up and down the length of the tool. A combination of bits on a machine could each make a cut in succession. One bit can make roughing, another semi-finishing and the last tool, finishing cuts. Broaches work like linear or rotary cutting tools, milling the outside and inside of metal workpieces.
Pillar drills or radial arm drills are common pieces of machinery in a metalworking shop. The presses are usually placed in a fixed position and are produced in different sizes. The drill chuck moves up and down and can be operated manually or mechanically. Drill bits are usually powered by electric motors that have variable speed drives. Attached to the end of a swing arm, radial drills can provide greater flexibility in the size of an established workspace.
Flycutters get their name from metal extrusions that appear to fly around a central hub as it rotates. These cutting tools can also be used horizontally or vertically, approaching or rotating around a fixed piece of metal. The bit could also be stationary, with a conveyor type of setup that takes the metal to the cutter. Fly cutters are usually used for internal drilling or precise external cuts.
Reamers drilled holes in the metal. Spindles can rotate and travel horizontally on a lathe-type machine, or they can move up and down like a drill press. Reamer cutting tools might include a drill-type bit, which has cutting edges around and along the length of the tool. Other versions may have cutting edges located only on the distal end of the tip.
