Slim3n

Makino’s new Compact Vertical Machining Center

Slim3n - A Compact Vertical Machining Center for High Volume Production

The Slim3n three-axis vertical machining center is a powerful, space-saving solution for turnkey and automated machining of components and parts. Suitable for both single-machine applications and as part of a multi-machine installation in a high-volume, low-mix production environment, the Slim3n expands Makino's portfolio of machines that are at the heart of its turnkey and automated solutions for market sectors such as automotive, die casting, medical and others.

Structure

Slim3n uses a fixed table design to provide customers with fixture design flexibility to meet requirements for increased footprint, heavier fixture weight, and ease of interface for a wide range of machining applications.

Finite element analysis (FEA) was used to determine structural stiffness and torsional rigidity to achieve optimal performance and consistent results. The structure of the machine is based on a closed frame design in conjunction with a pair of long support columns, resulting in excellent structural stiffness.

Spindle

Makino’s leadership in spindle technology is renowned throughout the world. Spindle rigidity, higher speed, constant pre-load, multi-plane balancing, minimum vibration and reduced thermal growth are key topics that Makino has pioneered through the art of spindle making by innovative design and manufacturing. The Slim3n comes with 2 spindle specifications 16,000 rpm and 8,000 rpm to cater to the varying machining applications for high volume production machinery industry demands.

Fixture and Rotary Workhead

Slim3n series is equipped with optional interfaces provided to meet the demands of the high volume production environment. With its capability to accommodate larger workpiece and fixture (measuring up to 975 x 500 x 580 mm with 400 kg payload), the Slim3n series gives higher value for money to the customers.


A milling machine that can also drill and tap well
With a 55mm spindle bearing diameter of 55 mm and an HSK-A50 spindle interface, the Slim3n is a vertical machining centre that does not afraid of the radial forces involved in milling. With a rapid traverse of 50 m/min and a Z-axis acceleration of 1.5 G, the Slim3n is also suitable for drilling and tapping applications.
 
Higher productivity for a wide range of applications and materials.
The workpiece in a Slim3n remains stationary on a fixed table (600 x 400 mm) with a load capacity of 400 Kg. The spindle moves relative to the stationary workpiece, allowing for greater travel in the X, Y and Z axes (500 x 400 x 400 mm). Motion characteristics of a Slim3n include: 50 m/min rapid traverse speed, feed rate is 20 m/min, acceleration/deceleration of the X and Y axes is 1.1 G, and that of the Z axis is 1.5 G.

The standard configuration of the Makino Slim3n includes a high-productivity 16,000-rpm HSK-A50 spindle that combines power, torque and speed for a wide range of materials and applications. The Makino Slim3n can also be configured with an 8,000-rpm HSK-A50 spindle for ferrous metals and applications that benefit from higher torque. With an armless, direct-access tool magazine that holds 26 tools, the Makino Slim3n can accommodate a wide range of tools.
 
Efficient Coolant System
Created for the production environment, Slim3n coolant system enhances the productivity. Configured with nozzle and flush coolant as standard features, chips are efficiently removed from the cutting zone. Slim3n structure is designed with a slope for quicker evacuation. A Lift Up Chip Conveyor option can be integrated at the rear of the machine to tailor to high chip generation demands.
 
Chip Management
A Lift Up Chip Conveyor option can be integrated at the rear of the machine to efficiently handle high chip generation demands. Slim3n can be equipped with other optional configuration to handle different component
demanding requirement.

Automation

The Makino Slim3n can be configured with an integrated, automatic pallet changer (APC) with a 550 x 380 mm pallet and a 4.5-second pallet change time. It can also integrate with a wide assortment of material handling systems, from manual operator transfer to automatic transfer featuring conveyors and loaders to unattended gantry and robotic systems.
