Efficient Solutions for Industrial Needs
Drilling and threading centre
Efficient and precise machine for drilling and threading operations. High-class machining combines speed, stability and optimal efficiency.
Shinzawa SV-50DT / SV-65DT – High-speed precision for serial production
The Shinzawa SV series represents the top tier of Drilling and Tapping Centres, emphasising extreme speed, dynamic stability and reliability. These machines are specifically designed for industries requiring high production volumes and short cycle times, such as component manufacturing for the electronics and automotive industries. The starting point of the design has been to create a compact yet robust machining environment that withstands continuous high-speed motion without compromising precision.
The machine’s foundation is an A-shaped column structure made of FC-300 cast iron. This low centre-of-gravity design and wide guideway span effectively dampen vibrations caused by 48 m/min rapid traverse and high acceleration. Mechanical rigidity has been further enhanced with internal V-shaped reinforcement ribs that prevent twisting and thermal deformation during long working cycles.
Technical performance and innovations
The heart of the SV series is a 12,000 rpm direct-drive spindle (DDS), connected directly to the motor to minimise power loss and vibration. The spindle, using a BT-30 taper, is optimised especially for high-speed drilling and tapping operations, where spindle acceleration and braking speed are critical factors. Tool changes are handled by a lightning-fast Clam-type Automatic Tool Changer (ATC), available in 16 or 21 tool station versions. The mechanical simplicity of the changer ensures minimal maintenance requirements and maximum reliability even after millions of change cycles.
To ensure precision, double-anchored, preloaded ball screws are used on all axes. This technical solution eliminates axial backlash and controls thermal expansion, keeping positioning accuracy constant throughout the working day. Efficient chip management is integrated into the machine’s structure: a spacious working area and steep protective panels guide chips and coolant directly to the conveyor, preventing heat transfer to the machine’s structures. The Shinzawa SV series is a technically mature solution combining a small footprint with exceptionally high production capacity.

Fast Clam-type Tool Changer
High-performance Clam-type Tool Changer enables extremely fast changes and minimizes downtime. Simple yet reliable mechanical structure ensures precise and repeatable tool changing, which is crucial for high-volume series production, where every second affects the overall efficiency of the production process.
High-Performance Worm
For machines, available direct drive, belt, or gear shaft driven worms according to processing needs. A suitable combination of speed and torque can be selected for different worm diameters, ensuring maximum efficiency and accuracy in fine mechanics as well as demanding heavy rough machining over the entire speed range.
Large Working Space
The machine’s spacious interior structure is optimized for easy loading of parts and maintainability. Steep protective shields and an efficient rinsing system quickly guide the parts to the conveyor, preventing heat buildup, improving user comfort and enabling the unrestricted use of large fixtures in efficient production.
Anchored Ball Screws
Bidirectional preloaded and anchored ball screws minimize the effects of thermal expansion and axial play. This design ensures excellent positioning accuracy and repeatability in high-speed movements, improving the machine’s dynamic rigidity and ensuring dimensionally accurate results in demanding machining conditions during long operating cycles.
