SDT200-3000 Eight-Axis Double-Sided Horizontal Machining Center

The SDT series eight-axis double-sided horizontal machining center is a dedicated and efficient machining equipment tailored based on the product drawings and processing technology provided by customers. This equipment adopts a layout structure of double-headed horizontal and mirroring at both ends. The spindles at both ends adopt spindle units with an interface of HSK-A100, which have the advantages of high precision and high rigidity. Equipped with a cutting function, it is easy to manually and quickly replace different types of cutting tools.

The biggest advantage of this machine is its low feeding height and close distance, which can greatly reduce the labor intensity of the operator. At the same time, chip removal is very smooth, maintenance and cleaning are particularly convenient, which can greatly improve production efficiency. It has the advantages of high precision and high efficiency. It is currently the most ideal processing equipment for high-quality and high-efficiency center hole processing of various shaft parts, and can meet the automated production and processing of truss robots or joint robots and automated connection.

Machine tool characteristics

Our company’s eight-axis double-sided horizontal machining center machine tools have been uniquely designed and optimized, with the advantages of high quality, high performance, and high economy. The main features are as follows:

Bed: This machine tool is a four-axis integral flat bed, adopting an integrated design, using advanced resin sand casting, after aging treatment, the casting has good stability and strong rigidity; the guide rail adopts a parallel arrangement of three roller linear guide rail structure support, with super strong mechanical stability and rigidity, and the chip discharge port is tilted to design smooth chip discharge. The linear guide rail replaces sliding with rolling, with small friction loss, sensitive response, and high positioning accuracy; it can bear the load in the up, down, left and right directions at the same time, and under the load, the track contacts with multiple lines, and the cutting rigidity will not decrease.

Spindle: using motor built-in spindle. Built-in three-phase asynchronous AC motor, stepless speed control by the driver

It has a high limit speed, large low-speed torque, compact structure, light weight, small inertia, low vibration, and noise

Low-level characteristics. High-precision composite ceramic ball bearings are reasonably arranged to make the product have the characteristics of high operating accuracy, high stability, large rigidity, and large bearing capacity. A circulating cooling channel is set inside the electric spindle. The cooling medium flows through the reasonably arranged circulating channel inside the spindle, quickly taking away the heat generated by the spindle rotation, making the spindle quickly enter a lower thermal balance state, thereby ensuring the size, stability, high precision of the processed product, and maintaining the long service life of the spindle. Intelligent monitoring sensors can be installed according to customer needs, which can monitor real-time motor temperature, bearing temperature, shaft core heat, elongation, spindle vibration, etc., to meet various intelligent control and processing needs.

Fixture: The hydraulic self-centering vice is adopted, with stable performance, convenient clamping, and strong clamping force. The optimized fixture has an adjustable structural design, which can be easily adjusted when the fixture is worn or displaced. It has an external fine-tuning mechanism, which is convenient and fast to adjust, with strong clamping force and stable performance. For workpieces of different lengths, the left and right fixtures are set to A1/A2 axes respectively, and the axial movement adjustment is carried out by programmable servo motors, which is convenient and flexible. After adjusting to the appropriate position, the fixture is locked and fixed by hydraulic braking.

Control system: Standard high-performance absolute value encoder servo system, high performance, good stability, no need to return to zero operation.

Machine protection: The machine tool adopts fully enclosed internal and external protection, which is beautiful in protection. Among them, the internal protection adopts stainless steel protection, which can effectively isolate the processing area, protect the motor, and can ensure the recovery of iron filings and cutting fluids. At the same time, it also facilitates the cleaning work and maintenance of the machine tool.

Machine control: optimized layout structure, low feeding height, close distance, smooth chip removal, suitable operation.

Lubrication system: The automatic depressurization lubrication system of this machine is centralized oil supply, and the advanced depressurization intermittent oil supply system provides each lubrication point with timely and appropriate oil supply in a timed, quantitative, constant pressure, and individual manner to ensure that each lubrication position is timely. Get lubricating oil, so that the machine can operate for a long time without looking back.

Chip removal system: Standard automatic chip removal machine, using the left and right ends at the same time built-in chip removal method, chip removal is convenient, easy to clean, reduce land occupation.

Tool magazine: Adopting 24 hydraulic tool magazine, providing tool storage position for the spindle, automatically selecting and positioning the tool through program control for tool exchange. Using hydraulic to provide tool change power, high stability, reliable tool change, and can support up to 25KG tool change.
