Technical Information

JD-320 CNC lathe adopts high-strength heavy duty cast iron, compact structure, good strength, proper hardness, low friction coefficient, and self-lubricating. The integral box structure of the base bed greatly enhances the overall rigidity and stability of the machine tool. It has the function of absorbing vibration, which reduces tool loss and improves the quality of the workpiece. It provides users with a guarantee of high efficiency and high reliability in use.

Main features of this machine ：

The 30° inclined layout greatly improves the bending and torsion rigidity of the machine tool at work. The integrated bed base with high rigidity and high stability provides a strong guarantee for the high precision of the whole machine.

The spindle unit is an independent spindle (sleeve type). The high-precision spindle system has undergone rigorous dynamic balance testing, with high precision, good accuracy retention, and good thermal stability. The maximum speed can reach 4000rpm. The high precision, high rigidity, high speed and high efficiency of the spindle unit enable the whole machine to not only finish finishing, but also to perform rough machining and heavy cutting for users.

The tailstock is hydraulically driven, and the sleeve automatically expands and contracts with good rigidity. Users can use the panel or foot switch to control it, which saves time and effort and provides high efficiency for machine tool processing.

The standard configuration of Taiwan SWIFT 12 station servo turret provides users with convenient, practical and reliable machining parts.

The feed system is directly driven by a servo motor with good rigidity, precision and dynamic response characteristics. The machine tool is equipped with ROLLER Taiwan HIWIN/PMI screw guide rail.

6. This machine provides users with a complete hydraulic and lubrication system, using high-quality hydraulic pumps and hydraulic valves and other components to greatly reduce the failure rate. The machine tool adopts centralized quantitative automatic lubrication.

Configuration
The cutting section of a turning tool consists of the main cutting edge, the secondary cutting edge, the rake face, the flank face, and the secondary flank face. Its geometry is defined by the rake angle (γo), clearance angle (αo), major cutting edge angle (κr), inclination angle (γS), minor cutting edge angle (κr'), and nose radius (rε). The selection of these geometric parameters depends on various factors and must be determined based on specific conditions. The rake angle (γo) is selected according to the composition and strength of the workpiece material; a smaller value is chosen when cutting high-strength materials. For example, when using a cemented carbide turning tool to cut ordinary carbon steel, the rake angle is set between 10° and 15°, whereas for chromium-manganese steel or hardened steel, it ranges from -2° to -10°. Generally, the clearance angle is set between 6° and 10°. The major cutting edge angle (κr) is determined by the rigidity of the machining system, typically ranging from 30° to 75°; a larger value is chosen when rigidity is poor. When turning stepped shafts, the angle is set to 90° or greater to suit the specific cutting method.

Material
The nose radius (rε) and minor cutting edge angle (κr') are generally selected based on surface roughness requirements. The inclination angle (γS) is determined by the desired chip flow direction and cutting edge strength. The configuration of the tool's rake face (Figure 2) depends primarily on the properties of both the workpiece material and the tool material. The simplest type is the flat rake face; a flat rake face with a positive angle is suitable for high-speed steel turning tools and cemented carbide tools used for finishing operations.
