Your website mentions stainless steel investment castings. Do you have casting capabilities in house?
Latva Machine partners with several investment casting houses who cast stainless steel, Titanium, aluminum, Inconel and other exotic materials. We work with these partners on the initial wax die design including gate locations and machined/cast surfaces to minimize costs. Just send us a print and we’ll take care of the rest.
Latva Machine supplies components for both airframe and jet engines with the turbine components being a majority of our work. Airframe components are made from aluminum, stainless steel and titanium with some made from investment castings. Turbine components are made from stainless steel, Inconel or Titanium depending upon the particular parts location. Inconel is used in the “hot” section of the turbine because it is capable of withstanding high heat.
Our facility in Newport, New Hampshire supplies precision machined, tight tolerance components from a wide range of exotic materials including Titanium, Monel, Inconel, Molybdenum and stainless steel. Our Alexander City, Alabama facility targets the automotive industry machining sand castings for truck and car engines, suspensions and frames in high volume into the millions.
Inconel’s machinability ranges from 12% down to 8% depending upon the grade. Inconel 625 and Inconel 718 are in the 12% range. Inconel 718 when heat treated to AMS 5663 is down to 8%. Inconel 600 machinability is 22%. Compared to 303 stainless steel which up around 75% machinability, Inconel is quite tough. Although with decades of experience, we don’t have any trouble machining Inconel.
Simultaneous 5-axis surfacing enables one-chuck multi-sided machining which provides outstanding surface quality and incredible dimensional accuracy which the aerospace and medical industries demand. Our Haas UMC-750SS with a 15,000 RPM spindle is robust and can easily handle exotic tough to machine materials such as Inconel, Titanium and Monel.
