How Hard Thread Turning Shortens The Process Chain

Figure 1. High rigidity allows higher process forces: Hembrug turning machines are especially suitable for high-precision hard turning.
High precision hard turning techniques are enjoying ever greater popularity in the metal processing industry. By shortening cycle times and increasing flexibility, high precision hard turning has advantages over grinding in particular when it comes to processing complicated parts such as spindle nuts or threaded spindles in the hard state.

Fast, Powerful, Accurate 5-Axis CNC Machining

The compact MU-4000V 5-axis vertical machining center from Okuma provides a large work envelope with high speed, process intensive machining combined with turning and 5-axis multitasking machining that is ideal for aerospace and other parts that require full 5-axis capabilities.
The MU-4000V vertical machining center from Okuma America is excellent for 5-axis multi-sided machining of parts for the aerospace and die/mold industries.

Twin Spindles with Individual Machining Zones

Tongtai MT Series has twin spindles and two individual machining areas.  The turrets and spindles are designed parallel to each other.  This design makes parts that usually need two processes to be finished on one machine. The work area on the main foundation of the lathes has two individual working areas with separate bed structures to decrease the transfer of harmonic vibration, contributing to excellent machining accuracy and high quality surface finishes.  The compact design allows for a short cutting flow from start to finish, which enhances machining rigidity and heavy cutting ability.  
Ideal for small automotive parts that are typically made within 60 seconds, Tongtai MT lathes from Absolute Machine Tools is designed for precision turning, high production volume, automatic production, and insertion into mass-production lines.

Single-Pass Taper Threading of Pipe

The Okuma LOC650 4-axis turning center used in the process applies tandem Seco multi-tooth, chaser-style threading inserts that are pushed through to direct cutting forces back into the machine. The stability and precision of the lathe, combined with the 4-axis design and this unique thread-cutting process, provides great results up to 7 in diameter in both accuracy and productivity. 
A LOC650 horizontal lathe from Okuma uses Thread Chaser inserts from Seco Tools to accurately thread oil coupling pipe in a cycle time of less than one minute.
