KM SYSTEMS

KM SYSTEMS is a manufacturer of precision machining tooling, specializing in grooving, threading, and indexable cutting unit heads. The product line includes unit heads designed for use with NG-series inserts (e.g., NG 2L, NG 2R, NG 3L, NG 3R), which are common in metalworking operations requiring repeatable thread profiles and groove geometries. The catalog features models such as the KM40TSS25HNEL3, KM40TSS25ENER2, KM40TSS12ENEL2, KM40TSNER3, KM40TSS25ENEL3, and KM40TSNSL2, each identified by manufacturer part numbers (MPNs) like 3955492, 3955487, 3955480, 3902286, 3955490, and 3902290. These unit heads are typically used in CNC lathes, multi-spindle machines, and automated turning centers where tool rigidity and insert clamping consistency are critical. The KM40 series designation indicates a standardized shank size and interface geometry, allowing interchangeability with compatible tool holders. The grooving/threading heads are built for moderate to heavy-duty material removal in steels, stainless steels, and non-ferrous alloys, with insert pocket designs that minimize vibration during interrupted cuts. Indexable thread cutting unit heads (MPNs 3950857 and 3950855) offer replaceable cutting edges, reducing downtime for tool changes. 3G Electric supplies these KM SYSTEMS components globally, supporting maintenance and production engineers who need to source specific MPNs for legacy or current machine setups. The product range does not include complete machine tools but focuses on the cutting unit heads that are wear items in high-volume manufacturing environments. Technical buyers should verify insert compatibility (NG series) and shank dimensions against their tooling system before ordering. 3G Electric provides logistics support for multiple SKUs, enabling procurement specialists to consolidate orders for these precision components alongside other industrial equipment.

Frequently asked questions

Common questions about KM SYSTEMS from 3G Electric.

What insert types are compatible with KM SYSTEMS grooving/threading cutting unit heads?

KM SYSTEMS grooving/threading cutting unit heads are designed for NG-series inserts, specifically NG 2L, NG 2R, NG 3L, and NG 3R variants. The 'L' and 'R' denote left-hand and right-hand cutting orientations, while the number indicates insert size (e.g., 2 or 3). Always confirm the insert geometry matches the unit head model; for example, the KM40TSS25HNEL3 uses an NG 3R insert. Using incorrect inserts can affect clamping force and thread accuracy.

What is the shank size specification for KM SYSTEMS KM40 series unit heads?

The KM40 designation in models like KM40TSS25HNEL3 indicates a shank size of 40 mm in width or diameter, depending on the tool holder interface. The 'TSS' and 'TSN' suffixes denote specific shank styles (e.g., square shank or cylindrical). For precise dimensions, refer to the manufacturer part number (MPN) and consult the product datasheet. 3G Electric lists MPNs such as 3955492 for the KM40TSS25HNEL3, which can be cross-referenced with KM SYSTEMS technical documentation.

Are KM SYSTEMS indexable thread cutting unit heads suitable for high-speed machining?

KM SYSTEMS indexable thread cutting unit heads (MPNs 3950857 and 3950855) are designed for moderate to high-speed threading operations in CNC lathes. Their indexable design allows quick insert changes without removing the head from the tool holder, reducing cycle times. However, maximum cutting speeds depend on workpiece material, insert grade, and coolant application. For high-speed applications, ensure the tool holder provides adequate rigidity and coolant flow to the cutting edge.

How do I identify the correct KM SYSTEMS unit head for my machine tool?

Identify the correct KM SYSTEMS unit head by matching the shank size (e.g., KM40) and insert type (NG 2L, NG 2R, NG 3L, NG 3R) to your machine's tool holder specifications. The manufacturer part number (MPN) is the most reliable identifier; for example, MPN 3955487 corresponds to the KM40TSS25ENER2 with an NG 2L insert. 3G Electric provides MPN listings for each SKU, enabling direct cross-referencing with your existing tooling inventory.

Can KM SYSTEMS grooving/threading unit heads be used for both external and internal operations?

KM SYSTEMS grooving/threading unit heads are primarily designed for external operations, as indicated by the shank geometry and insert orientation in models like the KM40TSS25HNEL3. For internal grooving or threading, specialized boring bar-style heads are typically required. Verify the tool's reach and clearance angles against your workpiece geometry. The NG insert series includes both external and internal variants, but the unit head itself must match the application.
