Standards

Description

Fillet (Radii)
In CNC machining, sharp internal corners on workpieces will naturally form fillets (radii). The depth of drilled holes should not exceed 12 times the drill diameter. For end mills, the depth should not exceed 10 times the tool diameter.
Threads and Tapped Holes
Diameter Φ1.5-5 mm, depth: 3 times diameter; Diameter Φ5 mm and above, depth: 4-6 times diameter. Zintilon can produce threads of any specification and size according to customer requirements.
Undercuts
Square profile, full fillet, dovetail profile.
Text
CNC Milling: Minimum width 0.3 mm, depth 0.1 mm. CNC Turning: Zintilon can use laser marking to create standard text for CNC turned parts. According to customer requirements, Zintilon can create standard text through CNC engraving or laser engraving.
Holes
Minimum drill hole diameter 1 mm. The hole depth should not exceed 4 times the diameter for optimal results.

CNC Router vs CNC Mill: Which CNC Machining Service Should I Choose?

CNC Router: Mainly used for engraving, drilling and cutting various materials such as wood, plastic, metal and composite materials. Suitable for machining large plates and soft materials.

CNC Mill: Compared with CNC routers, CNC milling machines are more suitable for processing hard materials such as steel and titanium. They usually have a higher Z-axis movement range, suitable for machining large block materials, and have a more solid structure and higher precision. CNC milling machines use spiral end mills, while CNC routers can use straight-edge router tools, but straight-edge tools are not suitable for metal machining

What Is the Difference Between CNC Lathe and CNC Turn?

CNC Lathe: Suitable for machining round or cylindrical parts, may lack the accuracy and speed of CNC turning centers, but suitable for producing small volume or custom parts

CNC Turn: Suitable for producing round or cylindrical parts, is a more advanced CNC lathe that provides wider machining capabilities. CNC turning centers are suitable for large-scale production that requires high precision and repeatability
