We mill castings with the highest precision — modern CNC meets traditional foundry expertise
Machining of aluminium and metal castings — precision CNC milling and conventional milling
As a production and machining plant, we specialise in milling aluminium and metal castings, offering both CNC milling and conventional milling. With advanced 3‑ and 5‑axis machining centres and an experienced team of operators, we guarantee exact shape replication, high repeatability and a superior surface finish. We machine castings in series and as single parts, tailoring the technology to the specific alloy and the customer’s technical requirements (die‑cast, sand‑cast, investment‑cast).
With a modern machine park and specialist cutting tools we mill complex castings to achieve perfect dimensional accuracy. CNC milling enables precise multi‑face machining, minimises distortion and delivers a consistent surface finish (Ra), which is crucial in automotive, aerospace, machinery and medical industries. Conventional milling remains indispensable for custom jobs, prototypes and non‑standard castings where process flexibility matters. We ensure on‑time delivery, top precision and machining adapted to the specifics of each casting to meet the most demanding expectations.
We specialise in high‑volume machining — we ensure efficiency and reliability!
We execute series production of machined castings with repeatability, precision and strict deadlines. Thanks to our modern machine park and skilled CNC operators, we process large batches while maintaining the highest surface quality. We optimise each stage to reduce scrap and cycle time, guaranteeing tight tolerances and dimensional conformity for every detail. Regardless of order size, we adapt to your needs and ensure dependable logistics and lead times across the EU/UK.
CNC turning of castings — precision turning for industry
rofessional turning of castings — accuracy, repeatability and excellent surface finish
As a foundry with an in‑house machining shop, we specialise in CNC turning and micro‑turning of aluminium and metal castings. We use CNC turning centres and conventional lathes to precisely machine castings of various sizes and complexity. Our processes deliver exact fits, repeatability and an excellent surface finish — critical in automotive, aerospace, machinery and medical applications.
We operate four CNC automatic lathes for efficient high‑volume turning, ensuring consistent results for every component. For customers requiring non‑standard solutions or prototype runs, our conventional lathes allow fine control of cutting parameters tailored to each project. We turn shafts, bushings, threads and parts with complex geometry, machining castings in aluminium, stainless steel, brass, bronze and engineering plastics. We guarantee high precision, short lead times and full support at every production stage.
We guarantee high‑quality machining of aluminium castings
Aluminium casting — before and after machining
Every cast part requires precise machining to achieve final geometry, smooth surfaces and compliance with the technical drawing. Before machining, a casting has a raw, rough structure and machining allowance that must be removed. Through CNC milling, CNC turning and grinding we deliver perfect smoothness, tight dimensions and readiness for assembly or end use. Our processes ensure repeatability, durability and the aesthetics of the finished part for the most demanding industries. On request, we also provide powder coating of aluminium castings in the full RAL palette, using paints from leading manufacturers and controlled surface preparation (including degreasing and grinding) for a top‑class finish.
Mechanical testing and heat treatment of castings — quality assurance
Material structure control and improved mechanical properties of castings
As a production and machining plant, we make sure every component meets rigorous quality expectations. On request we provide mechanical testing and material structure analysis to determine key parameters such as hardness, tensile strength and alloy behaviour. We also perform dimensional inspections (CMM), surface roughness measurements and provide documentation (FAI/PPAP upon request) to confirm compliance with your specification and GD&T.
For customers seeking even greater durability and stability, we offer heat treatment of castings — stress relieving, annealing, solution treatment and ageing (e.g., T5/T6 for aluminium) — significantly improving mechanical properties. These processes increase wear resistance, load‑bearing strength and dimensional stability. All tests and processes follow strict procedures to ensure maximum quality and reliability of our castings in demanding operating conditions.
Frequently Asked Questions — FAQ
Most common questions about machining castings, including milling and turning of aluminium castings
What is CNC machining of castings?
CNC machining of castings is precision subtractive manufacturing that achieves accurate dimensions, smooth surfaces and complex shapes according to the technical drawing. In our plant we perform CNC milling, CNC turning and drilling on modern machining centres to ensure repeatability and high‑grade components.
Which castings can be machined by CNC?
We specialise in machining aluminium, cast‑iron and brass/bronze castings, as well as other industrial alloys. Our machine park enables milling and turning of both standard and complex castings used in automotive, aerospace, machinery and hydraulic systems.
Which CNC techniques do we use when machining castings?
We use CNC milling, CNC turning, drilling, threading and grinding. These processes remove allowance and deliver the final geometry in line with the drawing. We also apply micro‑milling and micro‑turning to meet tight tolerances in demanding industrial applications.
Why is CNC milling key in machining castings?
CNC milling ensures precise surface generation, excellent finish and dimensional accuracy. Thanks to numerical control we can perform multi‑face machining, complex contours and precise holes/threads in one setup. Milling castings is essential in industries that demand high accuracy and repeatability.
