Appearance and Features
1. The machine head box and the bed, tailstock, pallet and other joint surfaces are manually scraped and polished, and the whole machine is tested which effectively guarantees the positioning accuracy of the Z axis and X axis, repeat positioning accuracy, reverse clearance and stability of the machine tool.
2. The machine tool adopts high-strength cast iron and hard guide rails with wear resistance and stability.
3. The machine tool spindle adopts high properties bearings, and the machine tool gears adopt precision grinding, which effectively improves the gear hardness and reduces the machine tool noise.
4. The machine tool, Z-axis ball screw, and X-axis ball screw adopts a tensile structure, which improves the accuracy of the outer circle and inner hole size of the workpiece.
Configuration Introduction
1. CNC Control System
The GSK980TB3i bus system is a high-performance CNC system developed by Guangzhou CNC Equipment Co., Ltd. The system adopts advanced control algorithms and high-speed processors to achieve high-speed and high-precision processing control. It supports multi-axis linkage control and can meet the processing requirements of complex parts. It has rich functions, such as tool radius compensation, tool length compensation, backlash compensation, pitch error compensation, etc. It also supports macro programming, graphic simulation, online processing and other functions, which are convenient for users to program and operate.
2. Manual chuck and tailstock
The standard configuration use manual chuck and tailstock that have the characteristics of simple structure, high flexibility, large clamping force, high precision, low cost, wide application range and easy operation.
CK6140, CK6150 with the three-claw manual chuck
CK6180 with the four claw manual chuck
The manual tailstock can be flexibly adjusted according to the processing needs. By rotating the handle, the tailstock sleeve can be moved forward and backward in the tailstock body to adjust the distance between the center and the workpiece. In addition, the tailstock can also move left and right on the lathe bed to accommodate workpieces of different lengths.
3. 4-station electric tool post
The 4-station electric tool holder can install 4 tools. Through electric control, the tools can be automatically changed and the tool change speed is fast, which improves the processing efficiency.
Frequently Asked Questions (FAQ)
Q: What is the standard CNC system configured on these machines?
A: The standard configuration features the GSK980TB3i bus system. It is a high-performance CNC system supporting multi-axis linkage control, tool compensations, and macro programming.
Q: What are the differences in chuck configuration between models CK6140, CK6150, and CK6180?
A: The CK6140 and CK6150 models are configured with a three-claw manual chuck, whereas the CK6180 model is equipped with a four-claw manual chuck.
Q: How many tools can be installed on the tool post?
A: The machines are equipped with a 4-station electric tool post, which allows for the installation of up to 4 tools and enables fast, automatic tool changes.
Q: How is the high positioning and repeat accuracy achieved?
A: High precision is ensured through manually scraped and polished joint surfaces (head box, bed, tailstock, pallet), high-property spindle bearings, precision ground gears, and a tensile structure design for both X-axis and Z-axis ball screws.
Q: Can the manual tailstock be adjusted for different workpieces?
A: Yes, the manual tailstock sleeve can move forward and backward via a rotating handle, and the entire tailstock unit can be moved left and right along the lathe bed to accommodate workpieces of various lengths.
