Description

Overview

The X4640 is a slant-bed CNC lathe configured for gang-tool machining and precision turning of medium-size parts. It integrates an HT300 cast iron slant bed, a built-in direct-drive spindle and industrial-grade components to support continuous production and accurate machining results.

Key features
  • HT300 cast iron slant-bed for rigidity and vibration damping.
  • SYNTEC 22TA CNC system with multi-machine and simplified programming functions.
  • Built-in direct-drive spindle with NTN 3+2 bearing arrangement for high-speed stability and accurate positioning.
  • PMI C3 ball screws and 30 mm PMI roller guide ways for precise feed and repeatability.
  • Hydraulic collet or hydraulic 3-jaw chuck; direct lubrication for consistent clamping accuracy.
  • Seven Ocean 40 L hydraulic station and 2 L automatic lubrication system for continuous operation.
  • Cooling/cleaning: Luikar 2V-30 pump with 120 L tank and filtration.
  • Full electrical cabinet with Schneider low-voltage components and internal heat exchanger; closed stainless inner fence and full machine cover for safety and cleanliness.


Machine parts (summary)
  • Lathe bed: integrated HT300 cast iron slant bed with high-temperature stoving varnish.
  • CNC system: SYNTEC 22TA controller—smooth, accurate control and easy programming.
  • Spindle: A2-5 direct-drive spindle (built-in motor) designed for heavy cutting and rigidity.
  • Collet & Chuck: 6-inch hydraulic hollow 3-jaw chuck or hydraulic collet with hardened contact surfaces.
  • Guide way & Screw: PMI 30 mm roller guide ways and PMI 3210 C3 ball screws with oil lubrication.
  • Bearings: NACHI bearings on ball screws for long life and precision.
  • Hydraulic: Seven Ocean 40 L (1.5 kW) for spindle cylinder, chuck and tailstock.
  • Lubrication: Ishan 2 L automatic circular lubrication for guide ways and screws.
  • Cooling & Cleaning: Luikar 2V-30 pump and 120 L tank with filtration for coolant delivery and chip removal.
  • Electrical box: Schneider components with heat exchanger and safety interlocks.
