Fielding an extensive lineup of state-of-the-art CNC machining equipment, Heartland Enterprises is leading the way in vertical turning operations producing large disks, rings, and other highly engineered parts for a variety of industries.

With capabilities to turn diameters as large as 42″, our advanced vertical turning lathes (VTLs) equipment manufactured by Okuma includes two CNC VTLs.

We cut a diverse range of materials including aluminum, cast iron, alloy steel, carbon steel, stainless steel, Inconel, titanium, and Waspaloy.  Besides our large diameter CNC turning capabilities, we offer in-house secondary services that include honing, thread forming, cylindrical grinding, and phosphating.  Our carefully vetted, highly reliable outsource partners can assist with thermal spray coating, flame hardening, Blanchard grinding, heat treating, ion or salt nitriding, carburizing, stress relieving, and induction hardening.  Our services are turnkey and we take the lead in all raw materials purchasing, machining, shipping, and subcontracting for an array of projects.  While our typical production runs range from 5 to 1,000 pieces, we’re also fully equipped for high volume production runs.

As an AS9100D / ISO9001:2015 certified organization, we pride ourselves in supporting large OEMs with disciplined quality control processes in order to ensure the best work possible. We strive to serve our customers with distinction and act as a long term partner for companies in the aerospace, military, agriculture, oil & gas, power generation, and semiconductor industries.
