Master 3.0

The new generation of MASTER CNC automatic machines represents the latest trends in industrial high-capacity material splitting.
The entirely new, extremely sturdy design of the feeding system with full-stroke vices and “jumping” fixed jaw of the feeding vice. The new concept minimizes residual material (120 mm) and enables the use of an additional vice behind the cut.
The fully automated CNC band saw is generally used for splitting large series even in the most demanding 24/7 operations and can handle heavy workpieces of large cross-sections. Continuous manual adjustment of the cut angle in the range of 90–45 °. The saw can cut material at an angle even in automatic mode.
The machine is equipped with material feed using an industrial servo drive with a new control system. 
The servo drive, together with a ball screw, provide high speed and maximum precision of material feed, even for multiple feeding when cutting longer pieces. Feeding can be set to three different speeds, 27, 42 or 50 mm/second according to the weight and the length of the processed material. The maximum length of a single feed is 500 mm. 
The entire robust design ensures an exceptional stability of the machine, even when cutting heavy workpieces. The latest concept of the arm casting, which is hollow and forms a closed section along its entire length, ensures maximum rigidity of the entire system, maximum cut precision and maximum service life of saw bands. Thanks to its compact dimensions, it fits in smaller workshops as well.
The central control panel with a colour high-resolution touch screen (7.0 ") provides easy intuitive control of all machine functions. The control unit allows programming of up to 60 programs for quick setting of the desired feed length for repeated production. Each program can be provided with a note, e.g. drawing number, PDF file with a drawing, setting of the workpiece height. You can program and cut various amounts of workpieces of different lengths without the need for additional machine attendance. The machine can be controlled in fully automatic or manual mode. 
Material clamping and feed of the band saw arm to the cut and back are controlled hydraulically. 
You can achieve maximum cutting productivity by setting the optimum saw band speed using a frequency converter in the range of 15–90 m/min. This also significantly improves cutting accuracy and service life of saw bands. 
The cutting tool is a 27x0.9mm industrial saw blade, which is produced in many variants and enables industrial splitting of a wide range of materials, including stainless steel or tool steel. For higher performance, the guide head of the saw band can be provided with automatic feed pressure control, which significantly increases the speed and cutting precision and the service life of the saw band.

The brand new MASTER concept brings the following benefits in particular:
-    Reduced minimum residual material (120 mm). 
-    Robust full-stroke clamping vices that move on massive linear guides and speed up machine setting when changing material.
-    The feeding system is fitted with a continuous roller track that eliminates material friction during feeding.
-    The jumping fixed jaw of the feeding vice eliminates unwanted material movement when backing. (Accessory)
-    The optical sensor can start a cutting cycle without the need for cutting already-cut material. It greatly saves time and material. (Accessory)
-    The machine concept allows the installation of a full-stroke vice also behind the cut. (Accessory)
-    The full-stroke solution of the vertical vices accelerates machine setting for bundle cutting. 
-    Pressure control of the feeding vice and the fixed vice as standard.
-    The new, robust design of the screw conveyor for chips ensures optimum removal of chips with minimum coolant content.
-    The stand-alone electrical switchboard with a central control panel allows optimum placement according to your operating conditions.

The new software of the MASTER concept simplifies and accelerates machine control and brings a whole range of new options:
- monitoring of service tasks – lubrication cycle, hydraulic oil change, cleaning, maintenance...
- notification via e-mail or SMS – end of the set cutting cycle, low material, broken saw band, states of emergency...
- managerial indicators of cutting productivity – cutting times, productivity of individual operators, consumption of saw bands...
- material guiding system with a precision cut feature

The maximum material feed accuracy results from the very robust design of the machine with all main parts made of grey iron and the sturdy design of the feeding system. The modern concept of the cast iron band saw arm allows for large cutting ranges for vertical as well as angle cuts.
The hollow parts of the arm contains all wiring and coolant lines, which protects them from damage.
The new arm concept also greatly simplifies saw band replacement or cleaning of the inside of the arm – you just open the hinged cover and it stays in the upper position. 
- The large diameter of the running wheels and the precise three-sided hardened steel blade guides ensure a long service life of the saw band and cutting accuracy.
- The oversized fit of the running wheels, the tensioning system and all rotating parts increases the service life of the machine.
- The saw band is driven by a quiet and maintenance-free industrial servo drive with a worm gearbox.
- The machine is connected to a complete cooling system with a powerful pump, enabling separate flow control on both guide heads and another adjustable outlet. The emulsion tank with a powerful pump is located in the machine base.
- Automatic check of the correct tension or tear of the saw band. When the saw band breaks, the machine automatically stops.
- Simple intuitive control using ergonomically positioned controls on the central control panel.
