Vertical Machining Center BA 1300
Highlights
State-of-the art universal vertical machining center for single part and batch production of small and medium lot sizes.
The special KUNZMANN features:
Construction
- FEM-optimized cast cross construction with C-column that carries the vertical spindle and the tool changer
- unique working area with large Y (750 mm) and Z (up to 900 mm) axis – perfect for the manufacturing of cubic workpieces
- linear guideways in X/Y/Z axis for dynamic axis travelling
- large ball screws in all axes (X axis 45 mm, Y and Z axis 40 mm) guarantee high stability
- pneumatic adjustment of the counterbalance in the Z axis supports ball screws, ensures dynamic axis movement, and improves surface quality
- numerous manufacturing options due to different spindle types
- highly efficient manufacturing process due to 38-/60-pocket tool changer
- Even the standard BA 1300 is equipped with a slat band chip conveyor and an individually adjustable bath rinsing.
Machine accuracy
- ground ball screws in all axes provide high-precision positioning and repeatability
- constant spindle temperature due to standard spindle cooling unit
- direct incremental linear encoder systems, sealing air-protected in all axes for precise processing (option)
Ergonomics
- working area directly accessible due to spacious front doors
- The machine table has a comfortable height (approx. 1,000 mm) and can be closely driven towards the front doors for optimum access to the clamping table and the workpiece.
- The movable and height-adjustable control console and the electronic handwheel facilitate machine setup and retooling.
- The smooth, inclined interior surfaces facilitate chip drain and cleaning.
- Additional service doors on both cabin sides make this machine particularly service-friendly.

Emulsion mist suction system
- Removal of oil and emulsion mist for a clean working area after extensive coolant use
- Health and environment benefit from pollutant reduction.
Linear encoder systems
Incremental linear encoder systems in all axes optimize precision and long-term accuracy.
The encoder systems are protected against contamination by sealing air.
Touch probe systems
Combined with the probing cycles of the control, triggering 3D touch probe systems facilitate setup, measuring, and monitoring during manufacturing.
Tool wear control/measuring
In addition to a fast tool wear control, the control also provides cycles for the automatic gathering of tool data during the manufacturing process:
- tool length
- tool radius
- tool wear
4./5. 4th/5th axis – CNC dividing heads
- CNC dividing heads are an economic and flexible extension for multilateral processing of complex workpieces.
- Machines can be used for simultaneous 5-side or 5-axis processing.
- Different designs meet individual requirements.
HEIDENHAIN TNC 620 Contouring Control
The HEIDENHAIN TNC 620 is a compact and versatile contouring control with 3 closed-loop axes and the option to add a 4th axis (B axis, e.g.) with a CNC dividing head.
Workshop-oriented programming with Heidenhain conversational programming language or DIN-ISO-Code, if required
- Cycles: drilling, leveling, pocketing, grooves, contouring
- 3D graphic incl. simulation
- automatic drilling of inclined holes (option)
- probing cycles for 3D touch probes
- USB and Fast Ethernet interface
- AFR (Automatic Feed Reduction): With this innovative control feature invented by KUNZMANN, the feed rate is adjusted automatically depending on the spindle load.
Advantages: protection of spindle and machine mechanics
HEIDENHAIN TNC 640 Contouring Control
Modern high-performance CNC control for 3D manufacturing of complex workpieces with short block processing time
Convenient program management due to included hard drive and USB/Fast Ethernet interfaces
Numerous graphic and simulation options
Special HEIDENHAIN TNC 640 features:
- programming with HEIDENHAIN conversational programming language, DIN-ISO-Code
- AFR (Automatic Feed Reduction): With this innovative control feature invented by KUNZMANN, the feed rate is adjusted automatically depending on the spindle load.
- CAD Viewer for viewing and analyzing current 2D and 3D CAD data (STEP or IGES, e.g.)
- CAD Import (option), direct input and processing of 2D/3D contours
- KinematicsOpt: special software option for convenient measurement of rotary axes; optimization of the machine’s rotary and swiveling axes. The KinematicsOpt cycle automatically captures, traces, and corrects geometric deviations.
- DCM (Dynamic Collision Monitoring):
The machine stops the axes if an internal collision with known components, such as clamping devices, tools or the main spindle, may occur. The system thus avoids machine damage and considerably supports the operator.
