Turning
Machining process in which the workpiece rotates and a stationary tool removes material. Ideal for rotationally symmetrical precision parts such as bolts, sleeves and shafts.
ductility
Ability of a material to deform plastically under load without breaking. An important criterion when selecting materials for safety-critical components.
duplex steel
Stainless steel with an austenitic-ferritic duplex microstructure – combines high strength with very good corrosion resistance.
E
measurement cycle
Calibration of machines and processes to ensure consistent dimensional accuracy throughout production.
Anodising

Endoprosthetics
Implantation of artificial joints (endoprostheses), such as for the hip or knee.
Deburring
Removal of sharp-edged material protrusions (burrs) generated during machining. Ensures the function, assembly and safety of the finished component.
initial sample inspection
Initial comprehensive inspection of a component prior to the start of series production to verify compliance with all specifications.
F
depth of manufacturing
Proportion of value added that is generated within the company itself. A high depth of manufacturing ensures quality, schedule adherence and flexibility.
Milling
Machining process in which a rotating tool removes material while the workpiece is fed in a defined manner. Enables complex geometries and precise contours – even from difficult-to-machine materials such as stainless steel, titanium or nickel-based alloys.
H
hard machining
Machining of hardened materials from approx. 54 HRC. Enables finishing after hardening and saves time-consuming grinding processes.
Harden
Heat treatment of steel to increase its hardness and wear resistance. This is achieved by targeted heating and rapid cooling of the material.
high-pressure sealing surface
Precision-machined surface that provides a reliable seal even under high pressure – e.g. in hydraulic and injection systems.
Honen
Honing processes for producing precise bore geometries and defined surfaces. Achieves the highest dimensional and form accuracy as well as low surface roughness.
I
implant material
Biocompatible material for medical implants, such as titanium Grade 5 ELI, implant steels or cobalt-base alloys.
Inconel
Nickel-based superalloy with excellent high-temperature strength and corrosion resistance – typical for aerospace applications.
Invar
Nickel-iron alloy with an extremely low coefficient of thermal expansion – ideal for dimensionally stable precision applications.
ISO 13485
QMS standard for medical devices. BEUTTER is certified to DIN EN ISO 13485 – up to and including components for risk class III.
K
Kanban
Inventory-controlled delivery and replenishment system that enables demand-driven, consumption-oriented material supply.
Class 1 component
Safety-critical component in aviation with special documentation and traceability requirements.
consignment stock
Consignment stock at the customer's premises from which items are withdrawn; payment is only made upon actual withdrawal. Reduces capital tie-up and ensures availability.
coordinate measuring machine
CMM – 3D precision measurement technology that records the geometries, dimensional, form and positional tolerances of components with high precision.
L
Lapping
Precision finishing process using loose abrasive grain to achieve maximum surface quality and flatness – used when the tightest tolerances are required.
contract manufacturing
Manufacturing of components to customer specifications and drawings, without in-house product development.
Batch size
Number of parts in a production batch. BEUTTER manufactures economically in batch sizes from 20 to 5,000 pieces.
M
measuring equipment monitoring
Regular calibration and monitoring of all measuring equipment to ensure reliable and traceable measurement results at all times.
N
Nitinol
Nickel-titanium alloy with shape memory and superelasticity effects, used inter alia in medical technology.
O
osteosynthesis
Surgical management of bone fractures using implants such as plates, screws and nails.
P
PEEK
High-performance plastic (polyetheretherketone) with high temperature and chemical resistance, used in medical technology and aerospace.
prismatic component
Cuboid or irregularly shaped workpiece that is machined predominantly by milling.
Profile grinding
Grinding with a formed grinding wheel to precisely machine complex contours and profiles into the material.
process validation
Proof of the reproducibility of a manufacturing process to ensure consistent quality on an ongoing basis.
R
framework contract
Long-term contract with agreed total quantity and flexible call-off schedule – for predictable serial supply.
Cleanroom
Controlled manufacturing area according to ISO 14644 with a defined low particulate level (e.g. ISO 5) – required for highly sensitive components in medical and semiconductor technology.
Rheometer
Rheometer.
Risk class III
Highest risk class for medical devices under the MDR, with the strictest requirements regarding evidence and documentation.
Crack testing
Non-destructive testing method for detecting the finest surface cracks, for example by dye penetrant or magnetic particle testing. Central to safety-critical components.
