Double face-grinding
Double-face grinding is a through-feed grinding process. The workpiece is guided between two grinding wheels using a conveyor system. This achieves short throughput times with high precision, plane parallelism, and excellent surface quality. nosta processes all common materials, from common steel grades to ceramics and plastics.

Flat and profile grinding
Grinding is used for the fine and finish machining of workpieces using surface grinding or profile grinding processes with a grinding wheel contour geometrically adapted to the component. On our high-quality machines, the workpieces are clamped using a magnetic chuck, a vacuum table, or mechanical clamping systems and zero-point clamping systems. Depending on the components to be machined, we use the pendulum grinding process, plunge-feed pendulum grinding, or creep feed grinding. A special feature at nosta are the High-Speed Grinding Nosta (HSGN) machines, which achieve peripheral speeds of up to 220 meters per second and very high Qw (time-to-cut volume).

Sawing
nosta uses fast and precise band, miter, and circular saws for both one-off and high-volume production. This process is supported by automatic loading and unloading devices using bar feeders and robots. Our technologies enable the use of high-performance cutting materials such as carbide and HSS for cost-effective production while maintaining the highest quality standards.

100% tactile/optical inspection in accordance with special agreements
Vibratory grinding - Barrel finishing
The rotary vibrators and centrifugal grinding systems used at nosta optimally perform intermediate and final machining of components. The processing spectrum includes improving surface quality, deburring, rounding, and polishing. The various system types and sizes allow for maximum flexibility when it comes to surface requirements, component dimensions, production batch sizes, and separation by material.
Component-assembly
- Assembly of components
- Completion of packaging units
Abrasive cutting
Abrasive cutting is a special cutting process in which the cutting process is carried out using a grinding wheel. The advantage lies in the combination of a two-step manufacturing process with high precision and geometric alignment. This eliminates downstream operations that would otherwise be necessary.
Packaging according to customer specifications
Packaging according to customer specifications: blisters, cardboard boxes, bags or Euroboxes
Welding - Embossing
Machine-assisted attachment of retaining elements such as ball and spring, tension and compression springs as well as resistance welding of leaf springs
Adiabatic cutting
Adiabatic cutting, also known as HSIC – High Speed Impact Cutting, completes the cutting processes used at nosta. This form of high-speed cutting with integrated energy recovery, in which the workpiece is "knocked off," results in very fast production cycle times with minimal material waste. In combination with coil feeding, this process is suitable for medium to large batch sizes.
Heat treatment / change of material properties
- Case hardening
- Induction hardening
- Hardening
- Nitriding
- Quenching and tempering
- and all other heat treatment processes
Milling
Nosta utilizes a state-of-the-art machine park consisting of 5-axis simultaneous milling machines as well as 4- and 3-axis milling centers, supported by robotics and handling systems. Machine extensions in the form of product-specific feeding systems or special clamping devices, implemented by our in-house mechanical engineering department, complete our range of services and enable us to support the entire product lifecycle. A special position in CNC machining requires rotary transfer milling machines with up to 22 axes. Six machining spindles operating simultaneously and automated loading and unloading enable the machining of complex components with short throughput times. These systems are supported by CAD/CAM and tool management systems.
Automated manufacturing
Automated production with up to 28 NC axes ensures maximum production efficiency. This machine concept, which is generally workpiece/component-oriented, is designed for high volumes with very high repeatability. nosta uses rotary transfer machines and linear transfer machines in combined processes such as turning, milling, drilling, notching, resistance welding, and marking. High-volume components are manufactured on PLC/CNC-controlled linear and rotary transfer machines. Furthermore, the company's in-house mechanical engineering enables the implementation of customized production machines that are optimally designed for the workpiece to be machined – independent of solutions available on the open market.
Wire erosion cutting EDM
Currently not available.
Laser cutting
Laser cutting is a type of thermal separation process using a a beam of concentrated light energy to cut material.
The available 4000watt CO2laser enables high cutting speeds with optimum material utilisation. The resulting short machining time, in combination with other manufacturing processes such as milling, turning, grinding, etc., makes it possible that products are manufactured in short time and cost efficiently.
Turning
Turning and milling operations enable the precise combination of turned parts and milled parts while adhering to the highest requirements for geometric and positional tolerances. Integration with CAM systems ensures efficient production with high quality standards. The machine park, consisting of CNC lathes, multi-spindle systems with automatic bar loaders, and turning/milling centers, supports the production of prototypes – from pre-series to series production.

FAQs about our manufacturing methods
We cover a wide range of processes: cutting (sawing, cut-off grinding, adiabatic HSIC), grinding (double surface grinding, flat/profile grinding, vibratory grinding), milling (5-axis, rotary transfer, robot-assisted), turning, and laser cutting with powerful CO₂ lasers.
One of our specialties is nosta mechanical engineering – we design and build custom systems for large-scale customer projects and for our measuring machines.
Machines developed in-house with automation are also used for keyways, T-nuts, wings, and radius grinding on longitudinal edges. Furthermore, wherever possible, we manufacture from profile material that best reflects the contour.
The results are competitive prices, resource-saving products, and optimal quality assurance.
For cutting, we use band saws, miter saws, circular saws, high-precision cut-off grinding, and adiabatic high-speed impact cutting (HSIC) – ideal for fast cycle times, minimal material loss, and burr-free production.
We offer double surface grinding, through-feed grinding, flat and profile grinding, as well as vibratory grinding/trowalizing – using High-Speed Grinding Nosta (HSGN) machines for extremely high throughput rates of up to 220 m/s circumferential speed.
The machine park consists of 5-axis simultaneous and 3/4-axis milling centers and rotary index milling machines with up to 22 spindles, some of which are CNC-controlled—combined with robot handling systems, CAD-CAM, and tool management for efficient complete machining.
