Length setting
arrangement used in PETRA DC300A POWER, a Stepper drive with brake coupled with Ball screw, which guarantees
consistency in length even after years of working , unlike other devices, whose
efficiency gets affected due to coolant, chips or dust. PETRA DC300A POWER
length setting system, actually sets the target / sensor at desired length
instead of moving the job and hence PETRA able to guarantee consistency in cut
lengths. PETRA DC300A POWER is designed for full capacity cutting irrespective of material (100% capacity utilization); hence it is equipped with a 4 Kw helical drive, which gives output of 5,5Kw at 87 Hz. It has been demonstrated during EMO-2009 exhibition in Milano, where DC300A POWER was cutting continuously during all days of exhibition, a material 42CrMo4 (Q+T) of 280 mm diameter at 100 sq cm / min with a blade speed of 100 meters / min using a Carbide blade. With 500 mm diameters of the band wheels and a blade size of 4150 x 34 x 1,1mm, DC300A POWER comes out with the best price-performance ratio. To keep the machine's coolant system free from metal dust in a 24x7 cutting environment, PETRA develops a new coolant cum filtration system for this machine model, which keeps the coolant free of metal dust to flow through the system. To keep the machine's work area free from chips, special coolant nozzles are installed at strategic locations, directs most of the chips to flow into the chip conveyor, making it one of the cleanest band saw machine. |

Blade attack angle can be changed with a just selector switch and whole arm, along with blade guides adjust itself to respective blade angle. Movement of the blade guide is automatic and moves along with the vise. This machine model has a capacity of 420 mm x 420 mm and is equipped with load / force mechanism on both blade guides, to negotiate cutting of wide size solid jobs and to control cutting conditions at entry and exit of hollow sections. Machine arm movement is based on PETRA's dual column platform, which ensures stick slip free movement and offers smooth and vibration free cutting environment. Its True 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. A strong engine of 4 Kw Helical drive generates more than enough power for cutting a 420 x 420 mm area with optimal cutting parameters. A robust construction of integrated support table with rollers, makes it easy to set a heavy duty job. A well designated control consol on the front door of this neatly covered machine, makes operator more comfortable. |

| 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. |

|
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. |
