Finishing 1. Machining · __ Grinding- __  A process that takes away material usually by spinning an abrasive surface against the material

· __ Lathe __ - A method for machining metal in which a piece of material is secured than spun into an opposing blade, surface, or bit · __ Milling Machine __ - Often referred to as the most complex of the machining processes the milling machine combines the movement of a cutting surface/bit with movement of the piece that is being machined, for fast production. Milling machines can machine parts with tolerances as small as .025 mm. · __ Drill Press __ - Drill Presses are used to machine a variety of accurate holes in parts, and quickly. The drill press is a mounted fixture (usually upright) that holds the part stationary while the operator slowly moves the bit into the part. Drill Presses have an advantage over regular drills because they are stationary and secure allowing for 100% precise angles and tolerances. 1. Finishing Techniques · __ Mill Turn __ - A machining Technique that secures a solid figure on a rotating base, while a moveable cutting surface machines the part. (most mill turn machines are computer controlled and can create complex shapes). Some large parts that are created by mill turn machines can take hours to be machined.

· __ Ream __ - A reamer or ream is a tool used in machining to make existing holes dimensionally more accurate and to improve surface finish. 

· __ Mill __ -Cutting and shaping materials into products using milling machines, or other machining devices

· __ Grinding __ -Is an abrasive machining process that uses a grinding wheel as a cutting surface, grinding provides relatively precise tolerances and can from a variety of finishes 1. Finishing Techniques (cont.) · __ Polishing __ - A method of finishing a machined surface so that it now has a smooth surface with precise tolerances, also, the new surface is indented to have significant specular reflection (the ability of the surface to reflect light without distorting or breaking it up) an insignificant diffuse reflection (the ability of the surface to break up and distort light) · __ Burnishing __ - The finishing of a rough surface to a smooth one by sliding material against another, which creates heat that will smooth the surface of the weaker material. Burnishing may occur in all metals in which the contact stress of the materials exceeds the overall yield strength of the weaker material.

__ De Burring __ - De burring is the use of natural rock/stones, or manmade ceramics to smooth the edges/surfaces of metal. <span style="font-family: Symbol; font-size: 16pt; line-height: 115%; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· __ Surface Treating __ - A bland range of industrial processes that are used to change the characteristics of a machined surface. For example to make a surface more resistant to corrosion by galvanizing it, or to alter a parts surface so that it better conducts electricity, such as **__plating__** a part with copper. <span style="font-family: Symbol; font-size: 16pt; line-height: 115%; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· __ Coating __ - Coating is a finishing technique that is applied to the surface of an object to provide it with certain quality’s for a variety of application

For example friction reduction. Corrosion resistance, increased solder ability and others. The technique is performed by joining the positively charged plating material (anode) with a negatively charged surface (cathode). For example the Pro Circuit/Monster Energy motocross team plates the front forks on there race bikes with a nickel coating to provide reduced friction and increased hardness.
