Heartland Enterprises supports OEMs with highly precise, large dimension, CNC milling services using the latest vertical and horizontal machining centers available today.  We perform milling, drilling, boring, contouring, counter-boring, countersinking, steel plate machining, forging, and casting for industries across the United States.  Our Okuma MA-600 4-axis horizontal machining center features a 39.37″ x 35.43″ x 39.37″ build envelope; and quick loading and unloading of parts using two 24.8″ x 24.8″ pallets.  To ensure maximum productivity, we’ve equipped the unit with auto gauging, tool breakage detection, high pressure coolant, and tool management software. For vertical machining, our 4-axis Mori Seiki MV-65B, Mori Seiki NV7000, and Okuma Crown 4018 units utilize rotary tables and feature an 8,000 rpm spindle speed.  Our Mori Seiki units can accommodate parts up to 60″ x 30″ x 29″ and our Okuma unit offers a 40″ x 18.1″ x 17.7″ build envelope. Our company is well known for large dimension CNC milling, especially for the machining of large-sized pistons used by multiple industries.

Featuring next generation computer controlled systems; all of our machining centers are operated in a cell to maximize productivity.  We offer a wide range of in-house fixturing to accommodate an array of parts, supported by quick-change pallet systems that provide accurate and repeatable setups.  Our seasoned staff, along with our state-of-the-art machining centers, can achieve tolerances as tight as +.001″.  All parts are subjected to a rigorous inspection process using a highly accurate probe measurement system. We’re capable of performing specialty, low, and high volume production runs for parts weighing up to 1,000 lbs.

We’re a turnkey provider for our customers, managing all raw material purchasing, manufacturing, subcontracting, and delivery.  We’re proud to serve the aerospace, oil & gas, agriculture, military, manufacturing, power generation, and semiconductor industries.  We’re also ISO 9001:2008 certified, practicing stringent quality control procedures to ensure that each part exceeds our customer’s expectations.
