KERN
Micro HD+
The plus in the name of the Kern Micro HD+ stands for the increase in axial and radial run-out accuracy, dynamics, rigidity and thermal stability, thereby enabling the applications of tomorrow. The Micro HD+ promises maximum process stability in the versatility of combined complete machining, freedom from wear and automated series production of high-precision components.
The revolution in the rotary and swivel axis
The high-precision bearing components, which are manufactured in-house with tolerances in the sub-µm range on a Kern machine, offer the best conditions for outstanding axial and radial run-out accuracy. The hydrostatic bearing creates an additional averaging effect of the bearing components, which neutralizes any remaining form deviations and shifts the running accuracy into the nanometer range.
By installing more powerful motors with higher nominal and peak torques as well as a topology-optimized structure, the swivel axis of the Kern Micro HD+ achieves significantly higher dynamics than CNC machines with comparable turning and swivel units. In combination with the Kern temperature management, it is therefore possible to manufacture dynamically and at high speeds with excellent machining accuracy over a longer
period of time.
A key advantage of the hydrostatic rotary and swivel axis with micro-gap is its rigidity. Combined with topology optimization of the housing and reinforcement of the swivel housing, we guarantee maximum stability. The use of hydrostatic bearings also contributes significantly to rigidity. This system is designed to ensure maximum precision even under high loads.
Another advantage is the increased thermal stability. While only the bearing plate and stator are usually cooled in variants with roller bearings, the HD+ also actively cools the bearing and housing in the swivel axis and the bearing shaft, bearing and stator in the rotary axis. The improved temperature management significantly increases the performance of the machine, especially in changing machining situations and demanding conditions.
Technologies
New benchmark in precision manufacturing
With its novel micro-gap hydrostatics, linear drives and advanced Kern temperature management, the Kern Micro HD is the new benchmark in precision, long-term stability and dynamics. Together with the know-how of our customers and the Kern application technology, the Kern Micro HD is unbeatable.
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.
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 Advantage
- 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
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
