Split Frame Clamshell CNC Crossbar

RANGE: 6.6″ – 76″ o/d / 168 – 1,930 mm o/d


The TAG Split Frame Clamshell CNC Crossbar combines advanced CNC precision with unmatched versatility. Engineered for external and internal bevelling, counter-boring, weld removal, flange preparation, OD turning, and more, it delivers consistent results on steel, exotic alloys, and titanium. With a user-friendly touchscreen control and seamless integration with TSFC-series clamshells, operators can achieve complex, high-quality machining in a single setup—saving time, improving accuracy, and reducing costs.

Description

The Split Frame Clamshell CNC Crossbar brings full CNC precision to field machining without changing the way your crew sets up. Built to integrate directly with TAG’s TSFC-series split frames, it turns a single setup into a complete machining workflow: perform an initial cut, then execute the programmed prep, or go straight to CNC preparation when time is tight. Servo-driven control and true two-axis interpolation deliver repeatable geometry and weld-ready finishes across the toughest materials.

CNC accuracy on a split frame: Single-point, fully programmable CNC crossbar for consistent profiles and surface finishes on TSFC-series clamshells.

One-setup efficiency: Mount once to rough cut and complete CNC preparation without repositioning, speeding turnarounds and reducing risk.

True X/Z interpolation: Two brushless axis drives precisely control tool path and bevel geometry for V/J, compound, and custom forms.

Wide process coverage: External V/J-bevel, internal bevel, compound bevel, counter-boring, weld removal, flange facing and preparation (flat face, raised face, RTJ groove, male & female), NORSOK compact flange machining, OD turning, radius prep, and heat-exchanger seal-face machining.

User-controlled programming: 7″ wired touchscreen remote pad with intuitive, license-free software; set rotation speed, feed, depth of cut, and trajectories on the fly.

Stable, chatter-resistant cuts: Servo-controlled rotation and robust crossbar architecture improve finish quality and reduce rework.

Power you can trust: Three-phase 380–480V electrical controller with servo motor provides smooth torque and repeatable speed control.

Machines the hard stuff: Proven on all steels, exotic alloys, titanium, and other hard materials while protecting tool life.

Fast field integration: Drop-in compatibility with TAG’s standard TSFC-series frames keeps crews productive with familiar fixtures.

Put simply, the Split Frame Clamshell CNC Crossbar combines the portability of a split frame with the precision of a CNC, so you can deliver code-driven accuracy, faster turnarounds, and consistent weld-ready results on any site.
