Product Description

5 Axis CNC Lathe Machine B20 Dual Spindle Swiss Type CNC Lathe for Pin

Main Features

Using the counter spindle and the back tool post, front and back processing can be performed at the same time.
Equipped with 3-axis lateral power head, lateral rigid tapping, front rigid tapping, back rigid tapping.
Equipped with no guide sleeve device, which is most suitable for high precision machining of short workpieces.
Adjust the chuck with the clamping force of the main shaft and the back shaft, which can easily clamp fine and precise parts. Fixed guide bushes and linked guide bushes have better benefits.
The main shaft oil-cooled electric spindle has no dead angle cooling at high speed, and it has more uniform heat dissipation and stronger performance than ordinary air-cooled electric spindle.
This machine adopts absolute operation, no need to return to the original point on and off, saving time and labor. Uninterrupted power supply for 24 hours, high efficiency and labor saving.

Application

Capable of turning and milling combined processing.
High-precision, wide-ranging and practical processing equipment.
Suitable for large-scale and large-scale "slender shaft" parts with relatively large length and diameter, and "small" and "abnormal" parts.
Wide processing range applicable to various high-tech industries such as medical, aviation, aerospace, automotive, motorcycles, communications, refrigeration, optics, home appliances, microelectronics, electronics, watches, mobile phones, etc.
Compound processing of precision, multi-batch, complex shape shaft parts and precision small parts.

Machine details

Frequently Asked Questions

Q1: What are the primary applications of the B20 CNC Lathe Machine?

A1: The B20 is designed for metal turning and milling combined processes. It is highly suited for high-precision, complex, and "slender shaft" parts required in medical, aerospace, automotive, electronics, and communication industries.

Q2: How does the dual-spindle system on this machine improve efficiency?

A2: By utilising both the counter spindle and the back tool post, the B20 performs front and back machining processes simultaneously. This dual-processing capability dramatically reduces cycle times and increases throughput.

Q3: What are the benefits of the oil-cooled electric spindle?

A3: The oil-cooled design ensures uniform, comprehensive heat dissipation without dead angles, even at high speeds. It offers superior cooling performance and structural stability compared to conventional air-cooled electric spindles.

Q4: Does the B20 require a guide sleeve to operate?

A4: The machine is equipped with a no-guide-sleeve mechanism. This configuration is ideal for the high-precision machining of shorter workpieces, minimizing leftover scrap and lowering material costs.

Q5: Which CNC system powers the B20 CNC Lathe?

A5: It features the LNC-T6800D CNC control system. The system runs on absolute operation, eliminating the need to return to the original reference point when powering on or off, thereby optimizing setup times.

Q6: What power requirements and footprint details apply to the B20?

A6: The machine has a total input power of 17 kW operating on 3-phase AC 380V (50Hz). Its physical dimensions are 2090x1200x1800mm, with a net weight of approximately 2100kg.
