Kern Micro Vario

Thanks to the sophisticated machine design, the unique Kern temperature management and high-quality components, the Kern Micro Vario reliably delivers the proverbial Kern precision and repeat accuracy.

Automation                                                                                                                                          

Kern CNC machining centres have standardised interfaces for all common automation systems. Due to the possibility of integrating a KERN into any existing production system, our machines offer the highest flexibility and safety for your automation task.
The automation of a Kern machine for tools and workpieces does not affect your service work in any way, the main door of the machine room remains accessible throughout regardless.

Your advantages

• 24/7 reliable serial production
• Significant increase in turnover - also in night shifts
• One operator for many machines                                                                                                                                                                                                                                                                                           

With the new integrated workpiece changer of the Kern Micro, you too have an easy way to enter the world of automation.

Benefits of 100% integrated automation:

• ‍24/7 operation (nights & weekends)
• Amortisation in less than 12 months
• No additional footprint
• No additional software or interfaces necessary
• Benefit from the high process stability of the Kern Micro       

Positional deviation is minimal

The positioning accuracy of the Kern machines according to VDI/DGQ 3441 is proverbial. Each individual machine is laser-measured and guarantees that the desired positions are approached with μ precision - from the first to the 10,000th workpiece in unmanned series production.

Position deviation Kern Micro: Pa = ± 0.5 μm
Position deviation Kern Evo: Pa = ± 0.5 μm
Position deviation Kern Pyramid Nano: Pa = ± 0.3μm 

• Highest machining accuracy on the workpiece
• Very stable processes due to reliable repeatability
• Reduced quality assurance effort

• Significantly less waste      

   

Product Design                                                                                                                                   

When designing our machine, we take into account all aspects of automated serial production - from automatic tool change to ergonomics at all access points.

Tool change

For fast and safe tool changes during the series production run, all Kern machines have the option of setting up the tool storage during machining. A large number of tool positions enables long autonomous run times, the tools are optimally and clearly arranged. The quick-change system of the Kern Micro is patented.
 

Ergonomics

The optimum accessibility and clamping height of each Kern machine ensure ergonomic working. The work area is bright and easy to see and accessible at all times through a main door, even when the machine is automated.                          

Axle kinematics
 

The product design of the Kern machines takes into account optimised axis kinematics in order to minimise the traverse paths, especially for small 5-axis parts. The most economical linear axes possible and generous swivel and rotary axes, as well as the optimised spatial arrangement of the axes, make it possible to produce even complicated free-form geometries with the shortest possible traverse paths in one clamping.

Patented machine stands

The symmetrical portal construction of the Kern machines with a machine stand made of Kern-Armorith (mineral casting, reinforced with heavy steel struts) suppresses practically all vibrations that occur due to its weight and its patented material.    

Temperature stability                                                                                                                        

Kern Microtechnik has developed a high-precision temperature management system for its machining centres that is optimally matched to the requirements of each individual Kern machine.
With the help of our own software algorithms, the heat is dissipated in a controlled manner at the points where it is generated. As a result, the Kern machines achieve a very high temperature stability without burdening the hall air conditioning.
By drastically reducing the sources of thermal errors, this intelligent control of the entire machine periphery, including the cooling lubricants, forms one of the foundations for our Kern potential.                                                                                               

Your advantages

• ‍Zero and kinematic points remain over a long period of time - often over a machine life
• High process stability leads to significantly reduced cost in quality control
• Amortisation of your investment with high energy efficiency
