Hardware · `Slim5n 4+1` · verification: source checked

The Makino Slim5n 4+1 is a compact 5-axis vertical machining center set up for 4+1 machining, with milling as its main function plus drilling and tapping. It uses a closed-frame structure with a pair of long supporting columns, and an HSK-A50 spindle available at 16,000 rpm or an optional 8,000 rpm. A 26-position armless automatic tool changer, through-spindle coolant and a rear lift-up chip conveyor support production part machining and automation.

## Study notes

- Machine structure uses a closed frame design with a pair of long supporting columns, developed using Finite Element Analysis (FEA) to improve structural rigidity and torsional stiffness.
- Two spindle specifications are offered: 16,000 rpm standard and 8,000 rpm optional; both use the HSK-A50 interface.
- Spindle design features constant pre-load, multi-plane balancing and reduced thermal growth.
- Cutting feedrate range is 1-20,000 mm/min.
- The 26-tool ATC is armless with direct tool pick and an integral door.
- Coolant provision includes through spindle coolant, nozzle coolant and shower coolant; work zone surfaces are sloped for chip evacuation.
- A lift-up chip conveyor is included at the rear of the machine.
- Automatic doors are included to assist machine tending; a robot interface is available as an option.
- Maximum workpiece is ø 800 mm x 435 mm, stated as being with limitations.
