Makino is the originator of high-speed spindles for commercial use. With spindles able to achieve speeds of 20,000 rpm and above, it’s no wonder we are the undisputed leader in high-speed high-efficiency machining center technology. Makino machines will deliver precise statistical performance and dramatically reduced cycle times.
Upgrading the productivity and machining accuracy, and realizing high reliability. Suitable for the parts of semiconductor manufacturing equipment, airplanes, and prototype units, in addition to commercial production parts of automobiles and construction machines. One-grade higher machining capability and machining area enhance the manufacturing power.
High rigidity machine construction
Pallet clamping system
Pallet can be precisely located on the pallet table with four taper-cones. Each taper cone supports and clamps pallet in a balanced manner. High cutting performance is realized even at the upper point on Y-axis.
Roller linear guides
Cylindrical roller guides are used in the X-, Y- and Z-axis. Rollers provide line contact area, which enhances rigidity and load capacities of the machines.
The two X-axis guides under the column are at different heights. This stepped design supports the machine to move at high speed and high acceleration mode by reducing the weight of column without compromising rigidity of the machine in Z-axis direction.
Advanced axis cooling system
Heat generation in the axes during high speed machining can affect accuracy and performance of the machine. The nx machine has the cooling technology of ball screw core and ball screw support bearing. Cooling oil is maintained as per the bed casting temperature and circulated through to the ball screws and end support
The machine body is designed to sit on the shop floor with only three-point support. This structure reduces installation time and makes relocation work easy.
Control unit that maximizes machine performance
Professional 6 optimizes machine motion, according to machining conditions. Even in machining with high-speed and high-acceleration, machining surface quality and shape accuracy can be kept. Machining efficiency is totally enhanced. A variety of machining modes are preset. Operator can easily choose suitable one for its purpose.
Advanced control technology (for reducing non-cutting time)
