Bundle clamping system / Nesting Fixture / Vertical Clamping
To cut bars in Bundle or to cut small diameter bars without slippage, these high performance machines are equipped with a strong, reliable and positive bundle cutting attachment or Nesting fixture.

Clamping vice (Vertical) is supported from both sides over columns and vertical motion is fully guided over Rack and Pinion. It makes it most sturdy vertical clamping system, with clamping force uniform over the width of the bundle.
Special Bundle clamping system for small diameter bars
PETRA Machines has designed and developed a Clamping System for Small Diameter bars in Bundle, which effectively hold the bars in position, allow machine to cut at optimum speeds and feeds,avoid burrs and increases the durability of the blade.


Front
 Back
This Clamping system for Small diameter bars in bundle has been successfully integrated with PETRA Machine's standard  Dual Column Bandsaw Machine Model DC300A.
Anyone cutting the small diameter bars in bundle knows,how difficult to cut. Practically speaking,it is not from the point of view of 'Cutting difficulty' of these diameter bars, but from the point of view of the its end result and henceforth its cutting and operational cost.
The main problem occur in a normal standard machine(even after using a correct TPI blade, speed and feed) are:
01.Burrs on the face of the cut piece.
02.Some times one of the bars in the bundle rotates and damages the blade.
03. Reduction in the blade durability.
Normal working pressure in a standard bandsaw may be 40bar, which may exert a force of 1 ton and this force is very high as far as 12 mm dia bars clamped in bundle is concerned.This high pressure tend to make the bundle gets disturbed and bars may jump of or even rotate.
At PETRA Machines, we analyzed these problems and concluded to have a reduced clamping pressure in the Feeding vise and a top guide at the shuttle vise, which would not exert any pressure on the bars, but shall touch the bars and restrict their upward movement and most importantly an extra vertical clamp just near to the blade at the exit. This clamp is a mechanical clamp with adjustments for various sizes and keeps the optimum pressure on the 'Cut lengths', to avoid any movement after the cut is over.
The unique feature of this clamp is , to reduce the feed at the 'near end of the cut' to avoid any damage to the bar edges. 

The machine is already having its standard vertical clamp at the front vise, behind the blade line.This comprehensive clamping system for such applications, has given the best results in terms of , nearly eliminating the burrs at the edges and improvement in tool life, with optimum speeds and feeds. Hence reducing the cutting time.
A 12mm diameter bundle (12mm dia x 14 no bars in a single row bundle) takes only 12 seconds to cut, mainitaining the excellent surface finish and durability of the blade.The results are excellent and encouraging too for other small size below 35mm diameter.

 Why PE-TRA Band Saw Machine?                                     read more...

PE-TRA DC300XL ToolMaster was engineered for metal cutting task where there is no need for large scale automated cutting and flexibility for ad-hoc cuts is preferred. The XL version has extended columns that provides for cutting materials up to 320 x 520 mm dimensions. Along the longer axis the piece is first cut 300 mm deep and then turned for the rest of the cut. This model is particulary suitable for small tool shops with limited space.
Every engineering detail was carefully studied and benchmarked against the competition in its class.
A workpiece of size  500mm (H) x 320mm (W) x 40mm (T) can be cut directly without turning it upside down.
DC300XL is a True Dual Column heavy duty band saw. The original Dual Column design assures structural rigidity. The Patented solution for precise, parallel movement of the frame including Ball Rail System on both columns provide superior fine movement of the frame eliminating both the influence of the center of gravity and cutting forces on the frame while greatly reducing the total weight of the machine and also minimizing the inherent vibrations. This alone assures an “advantage by design” in comparison to its competition.

The end result is a very precise cut and quality of the cut surface.
Machine is equipped with blade guards and awareness barriers for safety purposes according to CE norm.
