KELLENBERGER T80

• This high-precision collet-type spindle boasts a runout accuracy of less than lµm, making it the optimal choice for precision hard turning.
• Workpiece clamping is closer to the spindle bearing, resulting in higher machining rigidity and precision, resulting in better concentricity, surface finish, and roundness.
• Significantly increase the service life of cutting tools and reduce the cost of equipment usage
• The spindle can be directly mounted with a collet or three-pin chuck, eliminating the need for additional adapters.
• The chuck enables quick changeover between different processes with simple operation, eliminating the need for complex workpiece adjustments and alignment.

Using Kellenberger Hard Turning, the following accuracy can be achieved:

• Laser inspection Positioning/Repeatability: 0.004/0.003 mm (ISO230-2)
• Hard turning of parts with ahardness of HRC60 or higher
• Dimensional accuracy can be controlled to ≤0.005 mm
• Surface finish can be achieved to ≤Ra0.2 µm
• Part roundness can be fine-turned to ≤0.5 µm
• Contour accuracy ≤0.005 mm

Continuous machining accuracy is an important reference indicator for considering the thermal stability of machine tools. Hardinge standard CMA cycle test:

• CMA Value: 0.005 mm
• Spindle Speed: 1200 rpm
• Workpiece Material: Brass
• Depth of Cut:0.065 mm
• Ambient Temperature: 24.8-25.2 ^oC

Leveraging the inherent advantages of machines and years of experience in hard turning technology, the Kellenberger technical team provides solutions to customers in carious industries, optimizing machining processes, improving machining efficiency and tool life, and reducing the overall cost of equipment use.

The integrated 45° inclined bed design minimizes thermal deformation and distortion, achieving high-precision cutting performance and meeting high-precision part machining requirements. The 45° angle also facilitates chip evacuation. The bed is constructed of high-quality gray cast iron and utilizes the latest FEA finite element analysis technology to ensure an optimized structural design, ensuring superior strength, rigidity, and thermal stability.

The Spindle cooling device can timely cool the heat generated by the Spindle during rotation, effectively controllingtemperature rise and suppressing thermal displacement of the spindle box to achieve better processing stability.

The X- and Z-axes are equipped with high-resolution linear scales as standard, forming a closed-loop detection system that compensates for thermal displacement cau ion components, ensuring higher machinin in mass production.

The X and Z axes are equipped with Cl-grade ¢40 mm precision ball screws and Gl-grade 45 mm roller linear guides, enhancing the machine’s rigidity and vibration resistance during heavy cutting, ensuring superior heavy cutting capabilities.

Equipped with a standard MT#5 servo tailstock, it supports NC programming to achieve rapid positioning of the servo motor, enables programmable adjustment of the tailstock’s thrust force, and allows forward or backward movements during the machining cycle-meeting diverse process requirements. Additionally, an optional MT#4 dead center tailstock with a built-in precision rotating component is available; when used in conjunction with a dead center, it can enhance rigidity and precision.
