Makino Updates MAG1 with New Advanced Spindle Technology

Makino now offers more powerful spindle for increased metal removal rates

Mason, Ohio – September 2010 – Makino's MAG series of 5-axis horizontal machining centers are specifically suited to meet the just-in-time manufacturing needs of the aerospace industry. The newest offering in this series is the MAG1, a 5-axis machining center designed to handle quick, high precision aluminum production of parts up to 1500 mm.

The MAG1 is positioned to produce structural parts such as ribs, leading edges, and trailing edges of aircraft wing structures. The X-, Y-, and Z-axis travels of 1520 mm x 1100 mm x 1350 mm allow for part sizes up to 1500 mm x 1500 mm and 1300 kg. The MAG1’s construction features a three-point support system that eliminates leveling maintenance and reduces the cost of installation, and a 60-position automatic tool changer (up to 120 available), allowing continuous, uninterrupted machining.

Advanced Spindle Technology
Makino now offers a new 120 Kw optional spindle for the MAG1. This spindle maintains the same maximum RPM of 33,000 but delivers 50% more horsepower (HP). This enables increased metal removal roughing rates to as much as 500 cubic inches per minute in aerospace grade aluminum.  

Complimenting the additional power, this spindle also provides through spindle coolant capability - a first for any MAG series machine. With a through spindle coolant pressure of 1.5 MPa or 217 psi, this capability will be extremely beneficial in drilling applications. Manufacturers will also benefit from extended tool life as a result of direct tool cooling and added cutting lubricity.

The MAG1’s advanced spindle also features Makino’s third generation of Autonomic Spindle Technology (AST3). With AST3 the spindle utilizes displacement sensors to monitor forces against the spindle. During machining the data from these sensors is evaluated in real time. If an unsafe load condition is detected, the AST3 will reduce the feedrate to prevent damage to the spindle and tooling.

The spindle retains its compact design for easy access to deep pockets that most other machines cannot reach. The A-axis rotates between +100 degrees and -110 degrees to provide full 5-axis roughing and finishing. The B-axis resides on the machine side (NCRT), allowing the spindle to access the front and rear of the part and allows for four-sided fixture strategies.

Additional Features
The MAG1 also features Super Geometric Intelligence v.4 (SGI.4) control technology to allow for high feed machining without losing accuracy, and monitoring software for users to keep constant watch on bearing temperature and vibration during cutting.

The standard coolant system includes spindle head and terrace washing, ceiling showers, and table washing, which enable the MAG1 to maintain part accuracies during long machining periods. A center trough chip removal system assists high metal removal operation.

The automatic pallet transfer and storage system of the MAG1 integrates with Makino’s MMC2 system. Makino’s Continuous Pressure Hydraulics (CPH) system is also included to interface with hydraulic fixtures.
