Efficient Solutions for Industrial Needs
DT-Series slant bed Turning Center
You no longer need a separate CNC lathe and a separate milling/drilling/tapping machine. In most cases, a single DT-series turning center can meet all your needs with a single setup.
High-Performance Multi-Axis Lathe
The DT series lathe offers a DDS direct-drive spindle or a belt-driven spindle, rotating tools, and Y-axis capabilities. This series significantly expands machining capabilities by combining turning and eccentric milling. Thanks to the Y-axis, customers can replace more than 90% of the secondary machining of turned parts that would otherwise be done on a milling machine. This saves time and improves accuracy and efficiency.
Thanks to large-scale production, GreMat works hard to ensure that every customer receives excellent turning technology at an affordable price. You no longer need a separate CNC lathe and a separate milling/drilling/threading machine. In most cases, a single DT-series turning center can meet all your needs with a single setup.
Multifunctional Y-axis lathe
This DT-series turning center enables versatile eccentric milling, drilling, and threading directly on the workpiece being turned. It integrates the capabilities of a milling machine into a turning center, reducing the number of processing steps and the number of required setups. This shortens turnaround times, saves labor hours, and improves the dimensional accuracy of the finished machined parts.

Controls
The SL series is equipped with the popular Fanuc control system. The control package includes the AICC function, enabling high-speed turning.
Tool change
The SL series lathes are equipped with either a servo-driven or hydraulic tool changer. The tool changers have 8 or 12 positions, depending on the model.
VDI technology
The VDI system is a quick-release system for every tool holder on the tool plate. Thanks to this, tool changes can be performed in seconds rather than minutes, unlike with the traditional bolted Block clamping system.
Bar Feeder
The automatic bar feeder enables uninterrupted, unmanned batch production on a CNC lathe by feeding new bar stock into the spindle immediately after each workpiece is cut. The device minimizes downtime spent on material changes, ensures precise and stable material positioning, and dampens vibrations from the rotating bar. This maximizes the lathe’s utilization rate and enables efficient “lights-out” manufacturing.
Automatic tool measurement
The measuring arm reduces setup time to seconds and eliminates manual measurement errors. A highly sensitive touch sensor automatically updates the X- and Z-axis tool offsets directly to the machine control system. The sturdy and durable construction ensures precise repeatability even in demanding machine shop environments.
Oil mist collector
This powerful oil mist extractor removes harmful cutting fluid mists, aerosols, and fumes from the air in the CNC lathe’s work area immediately during machining. The device reliably filters the exhaust air and returns the separated oil or emulsion to the lathe’s fluid tank for reuse.
