Heavy Industrial Build Quality
STAR STL5 Production CNC Lathe
45° True Slant-Bed Turning Center · Model: STAR STL5
The STAR STL5 is an industrial-grade CNC slant-bed turning center engineered for precision machining of automotive, hydraulic, aerospace, and general mechanical components. Built upon a single-piece 45° true slant-bed monoblock casting, it combines superior structural rigidity with natural gravitational chip evacuation.
Powered by the world-renowned SIEMENS 828D CNC controller with ShopTurn dialogue programming, machinists achieve rapid part setup, animated 3D workpiece simulation, and rapid cycle execution. Supported by a 5.5 kW / 3.7 kW high-torque spindle motor and an 8-station PRAGATI servo disc turret, it delivers high-volume production throughput and sub-micron repeatability.
A2-5 Spindle 5,000 RPM
High-speed precision spindle with Ø48 mm bore and Ø40 mm through-hole capacity for bar feeding.
8-Station Servo Turret
PRAGATI SPT63 bi-directional disc turret indexing in split seconds for minimal non-cutting time.
Hydraulic 6" Chuck
SAN’OU 6-inch hollow hydraulic chuck and MT4 programmable tailstock with 300 mm travel.
Roller Guideways
HIWIN / PMI linear roller guides and ground preloaded ballscrews on X and Z axes.
Key Machine Features & Build Highlights
Every critical structural and motion component is selected from world-class machine tool suppliers for continuous production reliability.
HIWIN / PMI Roller Guideways
Both X and Z axes glide on premium linear roller motion guideways rather than standard ball type. Rollers deliver higher line contact, vastly superior load rigidity, and 20 m/min rapid traverse rates without stick-slip.
Hydraulic 6" Chuck & Programmable Tailstock
Equipped with a SAN’OU 6-inch hollow hydraulic chuck with Ø40 mm through-hole capacity for bar feeding, plus an MT4 hydraulic programmable tailstock with 300 mm travel for rigid shaft turning.
A/C Climate Control for Electrical Cabinet
Standard equipped with an industrial A/C panel refrigeration unit mounted to the electrical enclosure. Prevents overheating of the Siemens CNC servo drives, even in hot factory environments up to 45°C.
ABB & SCHNEIDER Electrical Architecture
The control enclosure features exclusively European ABB and Schneider relays, circuit breakers, contactors, and terminal blocks for long-term operational uptime and international compliance.
Automatic Lubrication & Coolant System
Automated centralized pump delivers metered lubrication to all linear guides and ballscrew nuts. High-flow coolant pump with directional turret nozzles ensures clean cutting and extended insert life.
High Accuracy & Repeatability
Laser interferometer calibrated for ±0.006 mm / 300 mm positioning accuracy and ±0.004 mm repeatability. Produces mirror finishes and tight ISO tolerance class fits directly off the lathe.
