BLM Group USA’s TS72 universal cold sawing CNC system for cutting tubes, bars and profiles features an automatic axis control function enables automated changeover for non-stop, unattended production. Particularly well-suited to small batch sizes, all adjustments and cutting parameters—material, blade type and tube dimensions—are all automatic so there is zero downtime and big productivity gains.
The TS72 can process tubes up to 102 mm (4 in.) outer diameter and part lengths up to 4,500 mm (177 in.). Round, rectangular, flat-oval and other shapes are all easy to load without needing special equipment. Four different lengths can be cut from each bar, and each length can be unloaded to different discharge positions. The saw automatically positions the different length parts on the bar to minimize waste and maximize material utilization.
As with all BLM systems, the TS72 has a user-friendly design enabling companies to achieve superior parts with minimal training. The touch screen monitor guides the operator through the few steps needed to start production. Optimized blade advancement profiles are stored in the CNC and are automatically selected based on material type and blade.
After sawing, the ends of the parts can be brush deburred both internally and externally, and an air jet effectively cleans the inside of each tube. The entire production may also be measured and certified.
An optional automatic washing system—thermally insulated and entirely made of stainless steel—can be used to clean the inside and outside of each tube. Each part is individually washed and dried for maximum efficiency. Finally, a bundle style belt collector can be added to speed up finished part packing.
Companies using BLM Group machines can gain efficiency by organizing multiple machine programs into work orders and sending them to each system via the network by means of Protube Express. Each batch and work order will contain the settings required to optimize quality and cycle times.

- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- outer diameter ( OD)
outer diameter ( OD)
Dimension that defines the exterior diameter of a cylindrical or round part. See ID, inner diameter.
- sawing
sawing
Machining operation in which a powered machine, usually equipped with a blade having milled or ground teeth, is used to part material (cutoff) or give it a new shape (contour bandsawing, band machining). Four basic types of sawing operations are: hacksawing (power or manual operation in which the blade moves back and forth through the work, cutting on one of the strokes); cold or circular sawing (a rotating, circular, toothed blade parts the material much as a workshop table saw or radial-arm saw cuts wood); bandsawing (a flexible, toothed blade rides on wheels under tension and is guided through the work); and abrasive sawing (abrasive points attached to a fiber or metal backing part stock, could be considered a grinding operation).
- sawing machine ( saw)
sawing machine ( saw)
Machine designed to use a serrated-tooth blade to cut metal or other material. Comes in a wide variety of styles but takes one of four basic forms: hacksaw (a simple, rugged machine that uses a reciprocating motion to part metal or other material); cold or circular saw (powers a circular blade that cuts structural materials); bandsaw (runs an endless band; the two basic types are cutoff and contour band machines, which cut intricate contours and shapes); and abrasive cutoff saw (similar in appearance to the cold saw, but uses an abrasive disc that rotates at high speeds rather than a blade with serrated teeth).
