Since 2013, Suzhou Excellence Intelligent Technology Co., Ltd. has been supplying reliable machine tools to workshops and factories around the world. This semi-automatic center lathe, equipped with an 8-inch chuck, a 1500mm bed length, a 400V AC power supply and PLC control, is designed to handle a wide range of turning, facing, boring and threading operations with consistent quality. The combination of a traditional center lathe structure and programmable semi-automatic cycles gives operators better control over cutting parameters and reduces repetitive work. Whether you are producing shafts, flanges, bushings or other cylindrical components, this lathe provides a dependable and economical solution for small-batch and medium-volume production.
Reliable Semi-Automatic Operation
The PLC control system lets you set the spindle start, stop, feed sequence and cutting passes for each cycle. This reduces the chance of human error and ensures every workpiece repeats the same machining pattern. The operator can switch between manual and semi-automatic modes, making setup and adjustment simple for different jobs. This feature is especially valuable when producing parts with tight tolerances, as consistent cutting conditions directly improve surface finish and dimensional stability.
Big Chuck Capacity and Long Bed
The 8-inch chuck securely grips workpieces up to a practical diameter for medium-duty turning. The 1500mm bed length allows you to machine longer shafts and bars between centers, which is essential for pump shafts, motor shafts, roller shafts and similar parts. The hardened and ground bed ways provide stable support under heavy cutting loads, helping to maintain accuracy throughout the entire bed travel.
Operational Flexibility
This center lathe can perform external turning, internal boring, facing, grooving, threading and taper cutting. By using the compound rest and tailstock, operators can quickly set up between-center turning. The gearbox provides a range of spindle speeds and feed rates, allowing the machine to work with carbon steel, alloy steel, stainless steel, aluminum and cast iron. All main controls are arranged for convenient access, so the operator can comfortably manage the machining process.

Precision and Stability
The machine structure is rigidly designed to reduce vibration and thermal deformation. Precision spindle bearings support the main spindle, delivering smooth rotation at selected speeds. The closed box-type bed and reinforced base further enhance stiffness. These characteristics help you achieve dependable machining results even on continuous production shifts.
Productivity and Operator Convenience
The semi-automatic cycle reduces manual intervention during cutting. After the first setup, the PLC controls the sequence, so multiple identical parts can be produced faster. This lowers the skill requirement for routine operations while allowing experienced technicians to adjust parameters for complex jobs. The ergonomic layout of handwheels and levers reduces fatigue, supporting longer working hours with fewer mistakes.
Safety and Maintenance
Safety is an important consideration for any workshop machine. This lathe is equipped with protective devices such as emergency stop buttons and splash guards, and the electrical cabinet is designed to meet IP requirements based on local standards. Daily lubrication points are easy to access, and the control system provides clear fault indications. Regular maintenance is straightforward, ensuring low downtime and longer service life.
Applications
This semi-automatic center lathe is suitable for general machining shops, maintenance departments, agricultural machinery repair, parts manufacturing and vocational training centers. It can be used for single-piece repair work as well as small-batch production because the semi-automatic function improves consistency without sacrificing flexibility.
- Turning stepped shafts and sleeves
- Facing flanges and discs
- Boring holes with the boring bar
- Cutting metric and inch threads
- Chamfering and grooving
- Between-center part support with tailstock center
Quality Management
Suzhou Excellence Intelligent Technology Co., Ltd. organizes its business process under an ISO9001 quality management system, which covers sales support, inspection coordination and after-sales communication. Before shipping, every lathe is checked for control functions, spindle rotation and basic alignment. We work with established production partners and provide clear technical documentation to help you set up the machine quickly.
Cost-Effective Machining
This machine fills the gap between a completely manual lathe and a full CNC lathe. It offers a moderate investment while delivering repeatable cycles, which is suitable for workshops that want to increase productivity without complex programming or a full-time CNC operator. The PLC logic is transparent and easy to modify for commonly repeated jobs, while the manual override remains available for repair work and one-off parts.
Technical Support and Documentation
We provide an operation manual, electrical schematic and test certificate with each machine. The PLC control wiring is labeled for easy troubleshooting. Our support team can also assist by email or video call to help with initial installation, parameter adjustment and maintenance guidance. Remote assistance has proven to be especially helpful for overseas customers who need quick answers.
Customization Services
Different markets may have different power grids, automation levels and safety requirements. The machine can be supplied with optional dual-voltage motors, additional safety interlocks or a digital readout for easier measurement. If you need a customized bed length, tailstock or chuck type, please send your inquiry and our team will evaluate the feasibility.
Trusted Export Partner
