Appearance and Features
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.
The machine tool adopts high-strength cast iron and hard guide rails with wear resistance and stability.
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.
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)
Q1: Which CNC control system is configured with these lathe machines?
The standard configuration features the high-performance GSK980TB3i bus CNC system, which supports advanced algorithms, multi-axis linkage control, tool radius/length compensation, and backlash compensation.
Q2: What are the differences in the manual chuck configuration among the CK6140, CK6150, and CK6180 models?
The CK6140 and CK6150 models are equipped with a three-claw manual chuck, whereas the CK6180 model is equipped with a four-claw manual chuck to accommodate larger workpiece setups.
Q3: How many tools can the electric tool post hold and how does it operate?
The machines are equipped with a 4-station electric tool post that holds up to 4 tools. It features automatic tool changes via electric control for fast operations and enhanced processing efficiency.
Q4: How can the manual tailstock be adjusted during machining operations?
The tailstock can be adjusted by rotating the handle to move the sleeve forward and backward. Additionally, the tailstock itself can move left and right on the lathe bed to support workpieces of different lengths.
Q5: What design features ensure the high precision and stability of the lathe machine?
Precision is ensured through manually scraped and polished joint surfaces (head box, bed, tailstock, and pallet), high-strength cast iron hard guide rails, precision ground gears, high-property bearings, and a tensile structure for the X and Z-axis ball screws.
