The a81nx is Makino’s next generation 630mm horizontal machining center. It reckons the industry superior work of its forebear with innovative design elements by centering on the large part as large feature challenges generally known in many industries.
The a81nx extends part size capacities through developede table and column castings that integrated with an additional 100mm of Y-axis stroke produce 12.5% more work envelope. To assure constant cutting throughout this new work zone robust 3-roller style B-axis table bearings are used. Most of the time, large parts mean large features. Tool length, diameter and weight capacities of the a81nx have all rocketed to back large face mills, boring bars and line bar applications.
There are two new spindle designs, which offer productivity developments in cutting and non-cutting performance. The optional 8,000-RPM high torque spindle increases constant power levels by 19% over the previous model. High torque spindle is optimally appropriate for hard roughing of iron castings and hard metal aerospace applications with the help of 50 HP of continuous power. Both the 8,000-RPM and standard 10,000-RPM spindles feature important developments in acceleration and deceleration, which in turn decrease rigid tapping times by up to 30%.
MAKINO A81nx design strategies include reliability and ergonomics. To make sure that the a81nx persists the Makino tradition of manufacturing HMC’s with the high quality, approved technologies like single piece X & Z axis way covers and servo driven ATC shutters are utilized. The ergonomic aim is simply comprehended just by paying attention to the design of the ATC magazine; they all (a81nx ATC magazines) consist of a tool loading station (TLS). This cam impulse device dislodges the tool from the pot into a rail guided tool drawer. In addition, maximum weight / diameter tools can be transferred in a secure and fast way.
