XTJs CNC Milling Capabilities

What is CNC Milling?

CNC milling is a subtractive manufacturing process that uses computer-controlled machines to remove material from a workpiece. Rotating cutting tools create precise features like slots, holes, threads, and complex contours. At XTJ, we provide 3-axis, 4-axis, and 5-axis CNC milling to produce parts ranging from simple flat surfaces to intricate 3D geometries, ensuring versatility for your designs.

Types of CNC Milling Operations at XTJ

We offer a range of CNC milling techniques to suit different project requirements:

face_mill

Face Milling

Creates flat surfaces and smooth finishes, ideal for large, even areas.

End-Milling

End Milling

Produces slots, pockets, and contours using the side and end of the tool.

Slot Milling

Slot Milling

Cuts narrow channels or slots into the workpiece for functional or aesthetic purposes.

profile_mill

Profile Milling

Shapes the outer contours of a part, often used for complex geometries.

thread-milling

Thread Milling

Machines internal and external threads with precision for fasteners and fittings.

Angular-milling

Angular Milling

Creates angled features like chamfers or dovetails for specialized components.

Materials and Surface Finishes Supported by XTJ Machining

Varies by material type, generally high hardness. Tool selection and cutting parameters should be based on specific composition, with attention to wear resistance and thermal stability.

Aluminum-

Aluminum (e.g., 6061, 7075)

Ominaisuudet: Kevyt, hyvä lämmönjohtavuus, helppo koneistaa, sirpaleet hajoavat helposti. Voi aiheuttaa työkalun tarttumista; vaatii asianmukaista jäähdytystä ja voitelua. Sopii korkeanopeuksiseen jyrsintään.

Teräs

Steel (e.g., stainless, carbon)

Ominaisuudet: Korkea kovuus, kulutusta kestävä, mutta aiheuttaa suuria leikkausvoimia ja lämpöä koneistuksessa. Vaatii matalanopeista jyrsintää kovilla työkaluilla (esim. karbidit). Ruostumaton teräs voi kovettua työstön aikana.

Titaani

Titaani

Ominaisuudet: Korkea lujuus, alhainen lämmönjohtavuus, lämpö keskittyy koneistuksen aikana, mikä aiheuttaa työkalun kulumista. Vaatii matalanopeista leikkausta, korkealaatuisia työkaluja ja riittävää jäähdytystä.

Messinki

Messinki

Ominaisuudet: Pehmeä ja helppo koneistaa, hyvä työstettävyys, lastut rikkoutuvat helposti, korkea pinnanlaatu. Sopii korkeanopeuksiseen jyrsintään, tuottaa vähemmän lämpöä.

Kupari

Kupari

Ominaisuudet: Korkea lämmönjohtavuus, muovautuva, alttiimpi työkalun tarttumiselle koneistuksen aikana. Vaatii teräviä työkaluja ja oikeanlaista voitelua. Lastut voivat olla pitkiä, joten lastujen poisto on tärkeää.

ABS

ABS

Ominaisuudet: Hyvä sitkeys, helppo työstää, mutta herkkä pehmenemään lämmössä. Vaatii hallittua leikkausnopeutta ja jäähdytystä sulamisen tai roskien välttämiseksi.

POM-Polyoksymetyleeni

POM (Polyoksimetyleeni)

Ominaisuudet: Kohtalainen kovuus, kulutuksenkestävä, itsevoiteleva, vakaa työstettäessä, hyvä pintalaatu. Ole varovainen lämpömuodonmuutoksen suhteen.

PEEK

PEEK

Ominaisuudet: Korkea lämpötilan kestävyys, kemikaalikestävyys, korkea kovuus. Vaatii kovia työkaluja, aiheuttaa suuria leikkausvoimia ja tarvitsee lämpötilan hallintaa muodonmuutoksen estämiseksi.

Polykarbonaatti-

Polykarbonaatti

Ominaisuudet: Läpinäkyvä, korkea sitkeys, mutta alttiina jännityskriisien muodostumiselle. Vaatii matalavauhtista leikkausta ylikuumenemisen välttämiseksi, ja terävät työkalut ovat välttämättömiä.

koneistus-Nailon-osat

Nailon

Ominaisuudet: Korkea sitkeys, kulutuksenkestävä, mutta kosteutta imevä ja alttiina muodonmuutoksille työstettäessä. Vaatii hallittua leikkausnopeutta, soveltuu matalavauhtiseen jyrsintään.

Carbon-Fiber-

Carbon Fiber

Characteristics: High strength, lightweight, but very hard. Prone to delamination or burrs during machining. Requires diamond or carbide tools, and dust protection is necessary.

Lasikuitu

Lasikuitu

Characteristics: High hardness, corrosion-resistant, but abrasive to tools and generates dust during machining. Requires efficient dust extraction and hard tools.

Elevate Your Parts with Advanced Surface Finishing

Enhance the durability, functionality, and aesthetics of your components with XTJ’s range of surface finishing options. Each process is tailored to meet specific performance and design requirements, ensuring your parts not only perform exceptionally but also look their best.

 

Anodizing

Durable and Versatile Coating for Long-Lasting Protection

Powder coating applies a dry powder—typically a mix of resin and pigment—electrostatically to the part, which is then cured under heat to form a tough, protective layer. This finish is known for its durability and resistance to chipping, scratching, and corrosion.

Bead-Blasting

Uniform Matte Finish for Enhanced Aesthetics

Bead blasting uses small glass beads propelled at high pressure to create a consistent, non-reflective matte finish on the surface of parts. This process removes surface imperfections and provides a clean, uniform texture.

Polishing

Mirror-Like Finish for Premium Applications

Polishing involves mechanically smoothing the surface of a part to achieve a high-gloss, mirror-like finish. This process enhances both the visual appeal and the tactile quality of the component.

Magnesium-osat

Enhanced Corrosion Resistance for Stainless Steel

Passivation is a chemical treatment that removes free iron from the surface of stainless steel parts, forming a passive oxide layer that significantly improves corrosion resistance.

XTJ’s CNC Milling Capabilities
