- Perfect structures and robust construction guarantee maximum rigidity and stability.
- All main components - bed, work table, column, crossbeam, saddle and headstock are made of high-quality MEEHANITE® quality castings
- Generously dimensioned guides in the X, Y and Z axes
- All guideways are hardened and ground (HRC50 -HRC55).
- The X and Y axes are equipped with with roller linear guide. As a result, the axes move with the highest precision even at high speed.
- Greatest machining accuracy and high damping thanks to wide, adjustable flat guides of the Z-axis for high drilling and milling performance with high spindle output torque
- Hardened and precision ground recirculating ball spindles mounted in high-precision bearings in all three axes for high rapid traverse speeds
- Cooling of the main spindle gear (gears, bearings, spindle) through an oil circulation system. Reduction of thermal expansion
- Operating status display (end of work light)
- Axle covers
- Work lamp
- Air pistol/water pistol
- Heat exchanger
- Spindle holder SK50 with a maximum spindle speed of 8,000 rpm with 2-stage gear for high precision
- Pneumatic counterbalance of the Z-axis ensures very high reliability and stability while multiple axes work at the same time. The SCBS system does not require an additional power supply or drive. This balance system achieves high speed and high processing precision
- Complete machine cladding with wide opening doors for ergonomic workpiece handling
- Automatic lubrication system with pressure control system
- Separation system for lubricating oil and coolant
- Installation elements
SINUMERIK 828D - The power pack in the compact class of CNC controls
Increased productivity and precision in production
- With CNC SINUMERIK 828D control from SIEMENS, users benefit from the fast and sophisticated hardware. It offers maximum ease of use and ensures good connections to a wide variety of storage media and networks. The basic structure of the CNC control corresponds to the standards of normal NC technology.
- As a top specialist for sophisticated milling machines, the Siemens SINUMERIK 828D masters all imaginable drilling and milling operations. Of course, this also applies to any pivoted workpiece planes and to cylindrical workpieces. You don't even need a special CNC control for mold making applications. The unique performance of the SINUMERIK 828D guarantees mirror-smooth surfaces with a minimum of machining time.
- For ergonomic operation and programming, the SINUMERIK 828D is equipped with a large 10.4-inch graphic color screen. Robust function keys and a complete QWERTY keyboard on the terminal enable the user to program, set up and operate even in a rough workshop environment. The mechanical keys are protected against dust and liquids in accordance with IP 65 by a stable and durable film.
- Since the SINUMERIK 828D works without components that are subject to wear, such as fans and hard drives, it is permanently maintenance-free and reliable. Powerful computers and memories enable modern NC strategies to be processed quickly and extensive color graphics to be displayed in real time, including in animated form. On the one hand, this increases the machining accuracy, and on the other hand, it simplifies operation, programming and diagnosis. The computing and storage capacity is so generous that moving graphics can be generated and shown for all functions as an aid as well as for programmed processing.
