CNC Turning

Intrex Aerospace is an industry leader in providing precision CNC turning components and system support for the complex needs of aerospace/defense/  space. We provide simple-to-complex shaped machined parts to these industries, along with a high level of integration and support documentation. Our facility is equipped with more than 35 CNC machines. We have twin-spindle CNC turning/mill lathes (7-axis), turn/mills (5 axes simultaneous), and vertical machine centers (4-axis). With our lineup of precision CNC equipment, we can produce machined aerospace parts in a wide range of sizes and complex shapes. Our machine working range is:

• 8” x 40” CNC turn/mill twin spindle lathes (6-axis)
• 6” x 6” CNC mill/turn (5 axes simultaneous) with ATC
• 20” x 40” CNC vertical machine centers (4-axis)

Turn Milling

Turn – milling is defined as the milling of a curved surface while rotating the workpiece around its center point. Eccentric forms or shapes that differ considerably from those produced by conventional milling or turning operations can often be turn-milled.

Why Use It?

Turn-milling is becoming more prevalent as a machining practice. The advances in CNC controller technology have led to better control of machine tools and their related axis. These advances allow for control of simultaneous motion of multiple axes. Because of these improvements, users are able to produce tighter tolerances and more complex geometries, while achieving finer finishes.

There are many advantages of turn-milling. Some of the more popular advantages we enjoy from are turn-mill machines are:

• Many of the parts Intrex produces have both turning and milling features. The ability to hold the part with a single work holding greatly reduces the need for additional setups. This setup reduction greatly reduces tolerance “stack up,”. This helps eliminate scrap and improves the overall quality of the machined part. It also contributes to operating efficiencies because of less operator intervention.
• With our latest machine tool additions of turn-mill machines, we can achieve simultaneous multiple-axis machining. The machine tools also have CAS (collision avoidance systems) that have the ability to identify and differentiate machine areas in relationship to work holding  and tooling, helping minimze crashes. The 5-axis turn-mill design allows tilting of the tool holder in relationship to the work piece.This allows the cutting tool to single point (no form tools) complex shapes, providing for better tool clearance and chip flow.
• Increased tool life and machined surface improvement is always a plus. Using simultaneous turn-mill technology, we are able to achieve improved tool life and cycle times. The design of our 5-axis machine tools allows for the tilting of the tool or chucking device, which helps maintain optimum cutting position and constant chip load. This improved multiple-axis control also helps produce better surface finishes.

In addition to our wide range of capabilities, Intrex has a team of knowledgeable machinists with more than three decades of aerospace CNC machining experience. Our Program Management team can manage the ever-changing demands of aerospace production and scheduling, and our demand planning experience and success in managing high-mix/low-volume aerospace components, paired with our ISO 9001 and AS9100 certification, offer a comprehensive, reliable program solution.
