Case Study | Centering and Facing

Stop Paying the Fixture-Swap Tax on Every Diameter Change

Every manual fixture change is unbilled downtime. The Midstates KN6HS approach replaces fixture-driven changeover with recipe-driven execution so part-family shifts happen at the HMI, not with wrench time. The result is faster response to demand with less excess inventory drag.

The Cost Leak in Traditional C&F

Traditional centering and facing lines can be productive on stable, narrow families. Once diameter variation rises, fixture logistics become the real line constraint.

  1. Fixture burden: operators may need to track 20 to 30 fixture variants.
  2. Switchover loss: each mechanical swap adds minutes of non-cutting time.
  3. Inventory distortion: teams overproduce to amortize setup, then carry excess stock.

The KN6HS Alternative

On the Midstates KN6HS centering and facing platform, the operator runs the next part size by selecting the recipe on the HMI and pressing start.

  • Changeovers move from minutes to seconds.
  • Mixed-batch and high-volume run on one operating model.
  • Schedule execution stops being limited by fixture swap labor.

Solution Architecture

Midstates configures Kira Japan KN6HS dual-opposed machines with programmable CNC sequencing for centering/facing and related multi-op workflows. Configuration is tailored to the part-family envelope, while the architecture remains stock-module based for repeatable support.

Configuration Envelope

Fixed Models

Z-axis stroke options of 250, 290, 400, and 800 mm (total travel up to 1600 mm).

Pallet Changer Models

Z-axis stroke options of 250, 290, and 400 mm for flexible automated part flow.

Extended Operations

Z-axis travel and dual-opposed architecture can support off-center machining in qualifying parts, including scroll-compressor style examples shown in the presentation.

Why This Wins Commercially

This is a throughput and cash-discipline decision, not a spec-sheet decision. Removing fixture-driven delays cuts setup friction, reduces avoidable WIP, and gives schedulers a faster response loop without adding headcount.
