1、 Product Introduction and Usage

This machine tool is longitudinal(Z)Horizontal(X)Two coordinate controlled CNC horizontal lathe. Capable of automatically completing internal and external cylindrical surfaces for various shaft and disk componentscircleConecircleCutting and processing of curved surfaces, end faces, grooves, chamfers, and other processes, as well as various turning processes such as metric straight threads, end face threads, imperial straight threads, and taper threads.CKA6150selectFANUCThe CNC systems of well-known domestic and foreign companies such as Siemens, Dalian CNC, and Huazhong Century Star can perform multiple repeated cycles of machining on workpieces.Suitable for the production of multiple varieties and small to medium batch products, especially for displaying complex and high-precision partsExcellentMore sexual.

2、 Main structural features

1. The machine tool adopts a traditional horizontal lathe layout. The overall design has good sealing and meets safety standards. The main basic components such as the bed frame and bed legs are all cast with resin sand and treated with artificial aging, resulting in superior overall stability of the machine.

2. The longitudinal and transverse motion axes of the machine tool are driven by servo motors, precision ball screw pairs, high rigidity precision composite bearings, and a semi closed loop control system with pulse encoder position detection feedback. The guide rail pair adopts the internationally popular high-frequency quenching (hard rail) methodThe "plastic pasting" process has fast response, high precision, and long service life for each motion axis.

3. High spindle speed, wide frequency conversion speed range, complete machinenoiseLow.

4. CKA6150The automatic transmission adopts a unique electronic control automatic shifting mechanism,The machine tool does not require stopping to change speed, and can automatically switch between high, medium, and low gears. The program can run continuously, greatly improving machining efficiency.

5. The appearance protection design of the machine tool follows the international trend, with a novel and unique shape, waterproof, anti chip, and easy maintenance; It reflects the characteristics of the times.

6. The diameter of the spindle through-hole is largeΦ82mmStrong rod material capability and wide applicability.

7. The machine tool operating system follows the principles of ergonomics, with the control box set independently and rotated,It can be moved at any position, making it convenient for the operator to use the knife nearby, which is a manifestation of humanized design.

8. Equipped with a centralized lubricator for ball screws andguide railForced automatic lubrication of the joint surface can effectively improve the dynamic response characteristics and screw of the machine toolguide railThe service life.

9. Bed saddle and skateboardguide railThe joint surface adoptsThe "plastic pasting" process allows for micro feeding of moving parts to prevent crawling.

10. Adopting an internal spray type without lifting the tool holder is more conducive to improving the surface quality of the workpiece and preventing coolant splashing.

11. Standard configuration of machine tool750/1000/1500The specification is fully enclosed protection;The rest are semi enclosed protections.

12. The standard configuration of the machine tool adopts a domestically renowned vertical four station turret. Special configuration can choose a six station horizontal turret;

13. Machine tools can be configured with manual, pneumatic, hydraulic chucks or manual, pneumatic, hydraulic tailstock according to user requirements.
