UNIMAT CNC 3-axis mill extended and SC spindle + TCT Control unit

Same as UNI-FRAES3 but 80mm, Y-, Z-travel and controlled milling spindle (164420 CNC)

Technical Education, TVET, Engineering, ... 

Especially for innovative education in higher classes,  Unimat CNC is an interesting option. Due to the modular construction, an almost infinte number of application possibilities arise. The Unimat CNC slides of the mill and the lathe are equiped with  2A steppers.

Some of the characteristics are:

• Cross Slide: travel 50mm (extendable)
• Longitudinal Slide: travel 145mm (extendable)
• Accuracy: max. 0.07mm
• up to 4 CNC axes controllable simultaneously

Vertical mill UNI-FRAES3EXT

 

Same as UNI-FRAES3 but 80mm, Y-, Z-travel and controlled milling spindle (164420 CNC)

 

Technical Data:

Number of CNC axes	3

The TCT Control unit is Included for controlling the UNIMAT CNC machine.

The pre-installed software allows for loading, manipulating and processing of ISO standard g-code files (RS-274). It also offers an editable tool table and tool path simulation. In addition to the manual also a training book for introduction to CNC and g-code programming is included.

This unit comes in a case, with parts for self-assembly

Particularly noteworthy are the low costs of this system. Instead of purchasing industrial machines  (high entry costs and ongoing expenditures, etc.), to which access is often not availabe to students, with Unimat CNC an entire machine park can be made available at only a fraction. Students can use this machines actively and autonomously.

The machines are controlled via the free software machinekit (fork of LinuxCNC, pre-installed on motion controller TCTCONT4) . This software can also be intalled for free on a common BeagleBone Black for training and simulation purposes.

What has been designed in a CAD application can be converted into machine code in a CAM application.
Machinekit offers a graphical interface as well as insight into and editing options for the G-code. For Fusion360 simple post processors with short manuals are available.

What is CNC – CAD/CAM?

The computerized manufacturing of a model starts with designing it on a PC. For this purpose a wide range of CAD (Computer Aided Design) applications are available on the market.

In the next step, the design file is opened with the CAM (Computer Aided Manufacturing)  software. The CAM application generates the tool paths based on your entered and defined processing parameters. These paths, as well as certain other machine commands, are converted into G-Code (normed programming language of numerical control). Most CAM applications can export such machine code in compliance with the RS274D standard (DIN 66025). G-Code for simple geometrical forms can also be compiled manually.

In the third and final step this code has to be imported into a CNC (Computerized Numerical Control) application. Line-by-line, the commands are converted into processing signals for the drive motors. The machine travels according to these directions and the work piece is processed.
