350M/350M-L/350MS/350MS With Sub-Spindle Slant Lathe for Long Shaft Turning and Milling

350M Series Slant Lathe Machine Introduction 

350M series slant lathe integrates 35º stepped bed guide rails (high and low rails), A2-8 high-torque electric spindle, and BMT65 power milling turret, the standard programmable hydraulic center frame, servo tailstock, optional sub-spindle and other functional components have launched a machining solution for slender shafts. Multiple processes such as turning, milling, boring, drilling, tapping, and reaming can be completed in one clamping. It can reduce the number of clampings and improve processing accuracy; shorten the product manufacturing process chain and improve production efficiency.

The 350MS turning-milling center is the ideal turning and milling solution for slender shafts. When the ratio of the length of a shaft workpiece to its diameter is greater than 25 (L/d>25), it is called a slender shaft, such as oil cylinders and piston rods, heavy machinery transmission shafts, screws, etc. During the turning process of such slender shaft parts, due to their poor rigidity, the slender shaft is easily bent and deformed under the action of cutting force, own gravity, rotational centrifugal force, and cutting heat, thus destroying the relative relationship between the tool and the part. The interpolation accuracy of the motion causes the processed slender shaft axis to produce wavy flow, which seriously affects the machining accuracy of the part. At the same time, the bending deformation of the slender shaft will also cause vibration in the process system, seriously affecting the roughness of the parts. At present, domestic and foreign manufacturers usually turn and mill slender shaft parts using long-stroke turning and milling composite centers, and use a hydraulic center frame for supporting processing. After the turning process is completed, they are then ground with a grinder.

1. The 350 series machine tools integrate the 35° stepped bed guideway, A2-8 high-power spindle, and servo turret or driven tool turret (milling turret).
2. The servo tailstock is standard configuration. Additionally, optional functional components such as a programmable hydraulic steady rest and a sub-spindle are available for machining slender shafts.
3. Multiple processes such as turning, milling, boring, drilling, tapping, and reaming can be completed with a single clamping. This can reduce the number of clamping, improve machining accuracy, shorten the product manufacturing process chain, and increase production efficiency.

Main Parts of Slant Lathe Machine

	Built-In Spindle The spindle is driven by a high-torque, high-efficiency, and high-performance permanent magnet synchronous motor. Additionally, P4 double-row short cylindrical roller bearings are adopted. This setup ensures the spindle's high precision, rigidity, and stability. Spindle Speed: 3000rpm Spindle Power: 26.5kW Spindle Taper Hole: Ф86mm
Sub-spindle The sub-spindle holds and turns a workpiece for it to be machined at the front and back sides. This means one clamping completes all or most of the turning processes, reducing manual intervention and improving the machining efficiency. Sub-spindle Speed: 4000rpm Sub-spindle Power: 22 kW
	Integrated Driven Tool Turret The driven tool turret is characterized by high positioning accuracy, a compact design, and fast. It enables tool changes without lifting, thereby boosting machining efficiency.
Servo Tailstock Servo motor control enables a rapid response to control signals, guaranteeing precise adjustment of position and clamping force during machining. This significantly enhances production efficiency and machining precision.
	Integrated Servo Turret The turret and the carriage are integrated and directly connected to the linear guideway, making the structure more compact. With the same structural dimensions, a larger end gear disc can be used, increasing rigidity and stability. When indexing and locking, the tool disc does not have a lifting action, which preserves precision, extends lifespan, and boosts the machine tool's machining efficiency.
Programmable Steady Rest Center frame interpolation is achieved by using an independent and compact screw drive mechanism to pull the center frame slide.
