Tube Cutoff

Round Tube Cutoff Machine

NEWCNCSTCOshort

The new CNC programmable straight tube cutoff line from Burr Oak Tool is the most flexible straight tube production system ever developed for the tubing industry. Feed length, speed, and batch sizes are all accurately controlled through the touch screen interface, maximizing the productivity of your processes and personnel.

This hitch feed design incorporates a belt driven linear actuator that positions an air operated clamp to allow a maximum of 36 inches of stroke length. The control of many aspects of the hitch feed can be determined by the operator at the touch screen interface. These include part length, number of parts required, and the actual feed speed.

When entering the part length, the programmable controller will automatically position the feed clamp and determine the correct number of hitching movements required to produce the final length. The operator can enter up to five different lengths and the machine automatically repositions itself each time the correct batch number is achieved, thus reducing set-up time. The feed clamp pressure is manually regulated to minimize clamping marks.

We offer all cutoff styles in single or double configurations and with end-forming capabilities.

Additional Options

We offer an extensive line of options to meet your specific production needs, including:
Permanent Aluminum Reels with Adjustable Hub Diameter	This option is used on the tube cutting machine when level wound coils are furnished by the tube mill without cardboard spools (Bare Pack).

Cardboard Reel Supports	Plywood supports with anti-friction bearings are available to support the tubing when furnished on cardboard spools.

STCO Tube Starter	A pneumatically operated 6 inch hitch feed tube starter is commonly used with ¾ inch diameter and larger to aid in lacing the tubing through the tube straightening mechanism.

STCO Tube Rounding Station	Normally used on ¾ inch diameter or larger to provide better ovality control prior to straightening.

Straight Tube Cutoff Machine Pull-Apart Feature	Helps in the production of a high quality cut profile with very little inside burr.

Straight Tube Cutoff Machine Adjustable Pull-Apart Unit with Break Off	Used in the processing of straight length tubing or when very short pieces are required from either coiled or straight length.

STCO Hitch Feed Unit	The hitch feed unit is available in either standard or tandem designs.
