CNC Part Cutting Service - Milling

When milling metal parts in a machining center, knowing your limitations and the possibilities to overcome them is important.  The convenience of CNC machining must not be mistaken for the complete absence of human interaction, especially as adjustments in calculations or programming are needed.  The conditions of feeds and speeds in cutting a high tolerance part will depend greatly on the material being CNC milled.  High tolerance parts also require sharp tooling for a consistent repeatable run.  Using qualified tooling is very important. When considering the use of qualified tooling the most common cutters are end mills.  End mills come in a variety of sizes, shapes, with or without coatings, and even the materials they're made from, being High-Speed Steel, Carbide or Ceramic.  There is a high degree of regularity and accuracy associated with the tooling used for CNC machining centers.

CNC machines are computer controlled and have the ability to move the table lengthwise in X axis, also moving towards and away from you in Y axis and a rotating spindle that moves vertically along the Z-axis.  This multi axis freedom lends itself useful with pocketing, engraving applications, 2.5D and 3D surfaces such as relief contouring when combined with the use of conical or ball nose tooling.  It also significantly improves the desired milling precision without affecting speeds or feeds, providing a cost-efficient option for most engraving work that would have been done previously by hand.

CNC Part Cutting Service - Turning

Turning metal parts in a turning center is setup and controlled by an experienced machinist.  Feeds and speeds for your custom precision cutting will also depend on the type of material being CNC turned.  The harder the material cut, the slower the RPM and feed rate.  High tolerance parts require sharp tooling.  Changing the inserts of the cutting tool may be required more frequently.  The Lathe employs static insert tooling for most of the OD and ID square shank type tooling within the turret.  The inserts also vary in material size, shape and coating.  If changing the insert is necessary, replacing with the exact same size insert will be critical to avoid having to change the program.  These inserts are also made with a high level of accuracy this precision allows for consistent part replication.   

CNC turning centers move the turret lengthwise in Z axis.  The X axis moves perpendicular to Z. These 2 axes’ combined with a rotating spindle that is often controlled as a rotary axis known as a C axis.  This C axis coupled with rotary live tooling mounted to the turret makes it possible for combining milling and turning functions within the same machine increasing part manufacturing speed as it lessens multiple machine set-ups.  Having a machine with Y axis gives you even greater flexibility.
