Raw Materials for Machining

 

Choosing the right materials is the key to a successful project. Materials have a profound influence on a product’s performance, appearance, and cost. CNC machines are capable of cutting a wide range of materials at very high speeds and feeds without sacrificing any quality due to the advancement of cutting tools.  

  1. Machinability – Materials with high machinability can be machined at higher speeds and feeds, CNC machine shops prefer materials with high machinability because they are easier to machine, require less tooling, and takes less time to finish. There are a large number of machine shops unwilling to take on projects with low-machinability materials. GTA CNC Shop, Toronto, with its 30+ years of experience is capable of handling the majority of CNC machining projects. It is easier to find multiple CNC machine shops that work with high-machinability materials to make custom CNC parts. Having a CNC project with high machinability material gives the ability to follow close tolerances with ease. The CNC Machining cost varies according to the machinability, for example, a low material removal rate will lead to higher CNC Machining costs because excess time is required to create the custom precision part. 
  1. Tensile strength is a material’s ability to resist tension caused by mechanical force. Tensile strength indicates a material’s ability to resist loads and stresses until it breaks. In order to measure tensile strength, specimens are held on opposite ends and pulled with a monitoring force until they fail. The higher the tensile strength, the stronger the part. It is necessary to thread the ends or shoulders of the specimen used for testing so that it can be held whilst being tested. With similar specimens it is possible to determine yield strength. Yield strength is the maximum force that can be applied before visible signs of plastic deformation appear. In general, stronger material will have a lower CNC machineability, thus costing more to produce custom parts.

Plastics

ACETAL or Delrin

​Polyoxymethylene also known as Acetal plastic is a thermoplastic material that widely used in automotive and electronic industries. The material required has low friction, high stiffness and excellent dimension stability. Acetal is mostly used in gear wheels, eyeglasses, ball bearing and locking systems.

PVC

Polyvinyl Chloride or also known as PVC comes in two basic forms. First is a rigid plastic material which is mostly used in construction pipes, doors and windows. Second is flexible forms that mostly used in cable insulation, electrical cable insulation, inflatable cables etc. PVC is the third most highly produce plastic material after polyethylene and polypropylene plastic.

​Nylon

Nylon in the family of synthetic polymer and mostly used in fiber cable, films, flooring, rubber reinforcement and shapes like car parts and electrical equipment. Nylon is a thermoplastic material that becomes flexible or moldable above a specific temperature and turns solid on cooling. Nylon plastic first used commercially in 1938 for manufacturing nylon bristled toothbrush and later on in 1939 it is introduced as a fabric at a New York World`s Fair.

Alloy Steel

AISI 4130

​AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. ​

It shows good overall combinations of strength, toughness, wear resistance and fatigue strength. ​Boiler Pressure Vessels, Tube & Pipe fittings, refinery equipment for elevated temperature service.

Carbon Steel

1018

AISI 1018 mild/low carbon steel has excellent weldability and produces a uniform and harder case and it is considered as the best steel for carburized parts. AISI 1018 mild/low carbon steel offers a good balance of toughness, strength and ductility. Provided with higher mechanical properties, AISI 1018 hot rolled steel also includes improved machining characteristics and Brine ll hardness.

AISI 1045 is a medium carbon steel designed to be able to function in areas requiring greater strength and hardness. This steel possesses excellent size accuracy, concentricity, and straightness which together enable to minimize wear in high speed applications. AISI 1045 can be formed into turned, ground and polished bars that can be machined unsymmetrically with limited distortion.

​12L14

12L14 bar is a standard resulfurized and rephosphorized grade carbon Steel, and a free machining steel. The added lead to the chemical composition provides improved machinability. Although the machinability is very good, the added lead content reduces the overall strength of this alloy. Typical applications include high-speed screw machine products, spindles, bushings, hose fittings and many other items where excellent machining characteristics can be fully utilized.

Stainless Steel

303

Grade 303 is the most readily machineable of all the austenitic grades of stainless steel. The machineable nature of grade 303 is due to the presence of Sulphur in the steel composition. Whilst the Sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. The corrosion resistance of type 303 is lower than that for 304. The toughness is still excellent as with other austenitic grades.Grade 303 is used in applications that require parts to be heavily machined. These applications include: Nuts and bolts, Screws, Gears, Aircraft fittings, Bushings,Shafts ​

316

​Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

​420

​Type 420 is a martensitic stainless steel that provides good corrosion resistance similar to 410 plus increased strength and hardness. It is magnetic in both the annealed and hardened conditions.
