Okuma Enhances 5-Axis Machining for Simpler, Faster, and More Precise CNC Operations

26 Mar 2025

5-axis simultaneous machining offers clear advantages over traditional 3-axis or indexed 3+2 methods: higher precision, reduced setup time, and the ability to complete complex geometries in a single operation. Yet its adoption is often limited by complexity and cost. Okuma addresses these challenges with an improved generation of 5-axis machining centres, combining advanced functionality with user-friendly operation and long-term cost efficiency. Designed for sectors demanding high precision and reliability — including aerospace, energy, automotive, and tool and mould-making — these machines support efficient, high-speed manufacturing with minimal manual intervention.

Industries such as aerospace, energy, automotive, and tool and mould-making depend on the reliable production of high-precision components. To meet these requirements, CNC machining processes must combine accuracy, ease of operation, and cost-efficiency. Okuma addresses these demands with its advanced 5-axis machining centres, enabling simultaneous machining of vertical, horizontal, and angular surfaces in a single setup — without operator intervention. This approach significantly reduces lead times and cycle durations while enhancing surface quality and overall process stability. The integration of 5-axis capabilities supports the use of complex machining strategies and optimised tool paths, resulting in improved cutting conditions, higher productivity, and increased process reliability. Additionally, the robust gantry structure contributes to dimensional stability and sustained precision across extended machining cycles.

Simplifying Access to Simultaneous Machining

A key enabler of user-friendly operation is Okuma’s proprietary OSP-P500 CNC control system, developed in-house and designed for intuitive use. It can be tailored to specific operational workflows, supporting rapid integration into existing production environments. Optional training courses facilitate a smooth learning curve, even for less-experienced operators. The 5-Axis Auto Tuning System enhances accuracy by detecting and compensating for geometric deviations and wear-related errors. Combined with Okuma’s Thermo-Friendly Concept, which offsets thermal distortions, the system ensures consistently high dimensional precision. The integrated Collision Avoidance System (CAS) further increases process reliability by simulating all machine axis movements in real time, proactively preventing potential collisions between tool, workpiece, and machine.

Performance and Cost-Efficiency in One

Okuma’s 5-axis machining centres offer compelling value, often outperforming traditional 3-axis solutions over the long term. Unlike 3-axis machines, which require additional software or hardware to approach similar performance levels, Okuma’s machines deliver advanced capabilities as standard. For instance, the GENOS M560V-5AX, equipped with 60 tool stations and X-Y-Z travel of 1,050 x 560 x 460 mm, is capable of machining a wide range of materials with high precision. The MU-4000V-L expands this functionality by combining turning with 5-axis multitasking for complex, high-speed, and high-precision operations. For heavy-duty applications, the VTM-2000YB features a swivelling B-axis spindle with a wide angular range and robust linear axes supported by generously dimensioned flat guides, ensuring both flexibility and machining stability across larger workpieces.
