The characteristics of CNC metal lathe for sale mainly include the following points:

Machine tool layout: The support plate of the inclined bed intersects with the ground plane diagonally, forming a right-angled triangle bed. This design makes the X-direction pallet of the inclined bed longer than that of the flat bed when the guide rail width is the same, so that more tool positions can be arranged.
Cutting rigidity: Since the tool cuts obliquely above the workpiece, the cutting force is basically consistent with the direction of gravity of the workpiece, so the spindle runs relatively smoothly and is less likely to cause cutting vibration. In contrast, when cutting with a flat-bed CNC lathe, the cutting force is at 90 degrees to the gravity of the workpiece, which can easily cause vibration.

Machining accuracy: The bed of the inclined bed CNC lathe is in the shape of a right-angled triangle, which directly affects the ball screw clearance in the X direction. Under the action of gravity, the reverse clearance during transmission is almost zero. This leads to a difference in repeat positioning accuracy between the two, which in turn affects the machining accuracy.

Chip removal capability: The inclined guide rail helps concentrate the iron chips in one direction, making it easier to achieve automated chip removal. In addition, the spindle traction torque of the inclined bed CNC lathe is small and the spindle speed is high. These characteristics help to improve processing efficiency and product quality.

Movement accuracy: The full-stroke straightness correction of the inclined bed CNC lathe is to ensure movement accuracy and good accuracy retention. In addition, the functional components of the system can be selected and clamped at one time to realize turning and milling functions, further improving processing efficiency.
Scope of application: The inclined bed CNC lathe is suitable for turning a variety of materials, including but not limited to internal and external circles, steps, cones, spherical surfaces, grooves, various threads and complex curved surfaces of ordinary parts. It is particularly good at processing medium-sized parts such as aerospace, bearings and electronics.

Structural strength: The inclined bed CNC lathe has a larger cross-sectional area and strong resistance to bending and torsion, which helps maintain the high accuracy of the machine tool

How to choose an inclined rail CNC lathe and what are its advantages

CNC  lathe with live tooling is a modern CNC lathe with a true ramp design that provides stable, high-precision machining operations. The main moving parts of the inclined rail CNC lathe are driven by the ball screw nut pair, linear guide rails and servo motors. The horizontal guide rails are inclined in pairs, with inclination angles of 35°, 45° and 60°. The inclined rail CNC lathe has the advantages of strong chip removal ability, good rigidity, high precision and smooth operation.

The structure of the inclined rail CNC lathe not only provides excellent rigidity and thermal stability, but also provides good overall quality and stability to the machine tool's castings. Incline rail CNC lathes offer excellent rigidity and can be used to handle and cut difficult materials or a variety of heavy-duty applications.

Model selection of inclined rail CNC lathes: Compared with machining center equipment with the same processing standards, the equipment purchase cost of inclined rail CNC lathes is more cost-effective. If there are no further process requirements, you can choose a inclined rail CNC lathe. Similarly, for economical and general-purpose CNC lathes, economical CNC lathes should be used as much as possible. But if you have higher precision requirements for the processing of some mold parts, you need to consider CNC milling machines and machining center equipment.

Incline rail CNC lathes are suitable for small and medium-sized batch processing of precision and complex rotating parts. The machine is equipped with power tools. In addition to turning functions, it also has axial and radial drilling, tapping and milling functions. Most inclined track CNC lathes have a low center of gravity and a short spindle structure, which reduces the loading and unloading intensity of workpieces. The design of the cutting knife row and knife row enables quick and accurate tool changes to save processing time and reduce maintenance costs. This is very beneficial to processors of shaft parts and cavity parts.

When purchasing an inclined rail CNC lathe, the same machine tool can be equipped with multiple CNC systems. An open CNC system with NC embedded PC structure or SOFT structure should be used as much as possible. The CNC software of this type of system is all installed in the computer, and the hardware part is just standardized universal and external 1/O between the computer and the servo driver. The interface is the same as that of various brands of sound cards, graphics cards and corresponding drivers on computers.

Advantages of inclined rail CNC lathes

Although the inclined track CNC lathe has a simple structure, it is very suitable for manufacturing medium-sized parts such as aircraft, automobiles, and generators. It can also be used to process various complex parts such as linear cylinders, inclined cylinders, arcs, threads, and grooves. Incline rail CNC lathes have many advantages, one of the significant advantages is better chip removal. Chips generated during CNC turning or machining processes will be rushed toward the chip bed by gravity and the normal flow of coolant, causing the chips to accumulate. What's more, this feature also reduces excessive wear on rails and other moving parts, extending the life of your machine tool.

Another feature of inclined rail CNC lathes is ideal thermal stability, which is advantageous in various machining operations, especially for heavy-duty applications. The angular structure of the base casting and the extended shaft guide provide great rigidity and excellent part accuracy. As mentioned before, the linear axis of the inclined track CNC lathe is longer, and the base saddle that carries the turret and tools also adopts a longer form to ensure sufficient support for the tools and turret.

In addition, the spindle of an inclined rail CNC lathe operates relatively smoothly, so high-performance parts and rigid structures minimize cutting vibrations. On the other hand, general flatbed CNC lathes have cutters, and the cutting force formed by the workpiece is at 90° to the gravity, making the operation more likely to cause vibration.

The main features of inclined bed CNC metal lathe for sale

The 30° inclined bed and base are integrally cast, with a wall thickness of 20mm, a square-shaped structure, reinforced ribs optimally arranged through finite element analysis, high-strength cast iron materials, resin sand molding, sufficient secondary aging and natural Aging, so that the basic parts of the machine tool have high rigidity and ensure the stability of the machine tool for long-term use;

Second, the X and Z axes all use linear rolling guides with high precision, high load capacity and high reliability, which have a lower friction coefficient than sliding guides. The rolling of steel balls can reduce the friction coefficient of the original sliding friction to the original One-fiftieth of the machine tool's feed speed and positioning accuracy.

Third, the high-speed, high-precision and high-rigidity cartridge-type spindle unit uses chromium-molybdenum alloy as the spindle material, and the spindle bearings use NSK spindle double-row cylindrical roller bearings and P4-level high-speed precision angular contact paired bearings, and use NSK high-speed lubrication. Grease, resistant to high speed and high temperature. The spindle unit is assembled in a constant temperature room. After assembly, it undergoes constant temperature running-in for 36 hours. After being put on the machine, it undergoes continuous trial operation for 36 hours to ensure the reliability of high-speed and high-precision performance. The φ65 spindle through hole and the φ52 drawn tube through hole enable this machine tool to have a larger processing range.

Fourth, the imported hydraulic turret is selected. The hydraulic motor drives the cutterhead to rotate, with large torque and smooth movement. The angle of the cam indexing mechanism is accurate and the tool change speed is fast. The clamping and loosening of the cutterhead is completed by the hydraulic cylinder, which is smooth and suitable. For heavy cutting, it has the function of selecting the nearest tool. The tool can be installed in the forward or reverse direction according to the user's habits.
Fifth, the feed in the X and Z directions adopts a C3-level double-nut preloaded precision ball screw. The servo motor is directly connected to the screw through a high-torque and low-inertia imported elastic coupling. The screw support adopts a pre-stretched structure. It can eliminate transmission backlash and pre-compensate the impact of thermal deformation on accuracy during long-term operation of the machine tool, ensuring positioning accuracy and repeatable positioning accuracy;
Sixth, the internal protection system of the machine tool has been optimized and professionally manufactured. It has reliable waterproof and chip-proof performance and can meet the requirements of high speed and low noise.
