Explanations and Technical Data for A5 LowCost Machine
Date August 2007
Our technical knowledge and our experience gave us the idea of generating a low-cost system with a smaller CNC-machine.
It is a low-cost system but this does not mean that we have neglected our standards concerning precision, easy handling, professional range of functions and reliability.
Some remarks for illustration:
Where we haven't economized:
- Rolled ball screws for precise positioning
- Supported linear guides with our KOSY linear profile
- Hardened guide rails and ball bearings as in our standard machines
- Strong and reliable stepping motors
- Multi-Controller MCS
- Connection to PC via safe serial port
- PC-independent control and supervision
- Microstepping, Spooler
- 3 AxesController
- Prepared for system add-ons (more axes, switch functions, depth controller, tool-length-measurer, scanning sensor)
- CAD/CAM/CNC-Software nccad version 7.5/Standard as machine-related licence
- The way from drawing to machining without change of program
- Contour-import via DXF or HPGL, re-editing functions
- Professional drawing and machining functions
- 2 1/2D-machining
- Manual and helps for initial training
- Proved security
Technical data see below.

Where we have economized:
- nccad-Standard version (instead of Prof.-version, 3D-functions and LookAhead optional)
- Travel ways like German paperformat DIN A5 (approx. 220 x 160 x 75 mm)
- Simpler construction
- ALU-parts are not anodized
- The Y-table is not milled plane, program and instructions how to do it is included
- With delivery as CNC-machine: minimal equipment of tools and accessories, consistent with the selected machining unit - 1 mill and 1 holder are part of the delivery, so that you can start milling at once - Files and instructions to make clamping devices are included
- Access to e-mail-hotline, no telephone hotline
What you can upgrade for extra charge:
- Protection hood aout of polycarbonate
- In/Outputs for controlling tasks
- 4th and 5th axis ( U and/or C)
- Turning units, small
- Y-table up to 500 mm
- Depth controller and scanner
- Tool-length-measurer
- Anodized Alu-parts
- Software-version "Prof." with 3D-machining and simulation, LookAhead
- Multi-licence of the software
