AWS D1.1 Certified Welding and Fabrication Services

West Coast Machining Services is proud to now be able to offer in house CNC machined components along with certified welding and fabrication services High Quality Welding and Fabrication for a Variety of Metals Carbon Steel The weld-ability of carbon steel is dependent on its chemical composition. Most carbon steels are high-iron, but other elements can be added to the steel to influence its welding capabilities. Welding carbon steel requires knowledge of the carbon content and equivalency of the steel, as well as its cooling rate and any other notable chemical composition concerns. Stainless Steel Recent experimentation and innovations in the production of stainless steel has resulted in a variety of materials with enhanced performance and aesthetics. Welding stainless steel is relatively straightforward. The process is similar to welding carbon…

High Speed Machining Leading The Way In Jobbing Shops

High Speed Machining Leading The Way In Jobbing Shops

High speed machining is usually associated with any spindle speed above 15k rpm, but it is much more than just a faster spindle. The whole machine must be considered when selecting a good candidate machine for HSM. Thermal compensation, overall machine rigidity and construction, positional feedback, the motion control system, tool retention, and many other characteristics must be looked at, in detail, before determining that a particular machine is suitable for the task. Traditionally, finish High Speed machining of hardened materials was performed by the use of EDM technology; and although this process was very effective, shops were continuously looking for faster and more efficient ways to produce their products. Eventually, as CAD/CAM software technology evolved, and new and more productive toolpath generation became available, the use of these advanced…

Cryogenic Machining Drastically Improves Cycle Times

Cryogenic Machining Drastically Improves Cycle Times

Liquid nitrogen insert cooling extends insert life and allows greater use of low-cost ceramic inserts for hard turning cryogenic machining operations. Cubic boron nitride (CBN) and polycrystalline cubic boron nitride (PCBN) inserts have traditionally been the tools of choice for hard turning applications. However, many shops contemplating hard turning are turned off by their high price. A new extreme-temperature coolant method has been developed to offer longer insert life, faster cutting rates and more affordable hard turning insert options. The Icefly cryogenic machining coolant system from Air Products (Lehigh Valley, Pennsylvania) delivers a jet of –320°F liquid nitrogen directly to the insert during turning operations. The liquid nitrogen raises insert hardness, which significantly reduces the thermal softening effect that an insert may experience as a result of hard turning inherent…

Optimized Milling Strategy for Five-Axis Titanium Blisk Machining

Optimized Milling Strategy for Five-Axis Titanium Blisk Machining

Optimized Milling Strategy for Five-Axis Titanium Blisk Machining - Many of the new designs for both military- and civil-aircraft turbine engines feature blisk rotors instead of single-bladed rotor assemblies because of their significant weight reduction, greater resilience and reduced maintenance. Blisks are usually machined from a solid billet of hard, exotic materials, such as titanium and nickel-based alloys, which makes them difficult to machine and leads to long cycle times. Subsequently, these components become very expensive to produce. As a result, efficient machining methods need to be developed. Swiss machine tool builder Starrag (Hebron, Kentucky) has addressed these problems by developing a new tooling concept and milling strategy for roughing, semi-finishing and finish-machining blisks. The centerpiece of the improved Optimized milling strategy is the finishing operation, which helps to reduce the…
