Použitý šikmý soustruh DMTG HK7516 na prodej

An oblique lathe, also known as a slant bed lathe, is a type of lathe that features a slanted or inclined bed instead of the traditional horizontal bed found in standard lathes. This design offers several advantages, including improved chip evacuation, enhanced rigidity, and better accessibility to the workpiece. Oblique lathes are commonly used in modern machining to achieve higher efficiency and precision in turning operations. Here’s a detailed description of an oblique lathe:

Description of an Oblique Lathe (Slant Bed Lathe):

An oblique lathe, or slant bed lathe, is a machining tool designed for turning operations on workpieces. The distinguishing feature of this lathe is its slanted bed, which positions the spindle and cutting tools at an angle to the horizontal plane. This design offers various benefits that contribute to improved machining performance and operator convenience. Here are the key components and features:

Key Components:

1. Slanted Bed: The slanted bed provides a tilted surface on which the main components, such as the headstock, carriage, and tool post, are mounted. The bed’s inclination helps with chip evacuation, rigidity, and better access to the workpiece.
2. Headstock: The headstock houses the main spindle that holds and rotates the workpiece. It contains gears, a motor, and other components for controlling spindle speed.
3. Koník: Located at the opposite end of the bed from the headstock, the tailstock supports the other end of the workpiece during machining. It may be adjustable for accommodating different workpiece lengths.
4. Carriage: The carriage moves along the slanted bed and holds the cutting tools. It includes the saddle (which moves along the bed) and the cross-slide (which moves perpendicular to the bed).
5. Nástrojový sloupek: The tool post securely holds the cutting tools and can be adjusted to position the tools accurately for machining.
6. Spindle Speed Control: Oblique lathes feature spindle speed controls to adjust the rotational speed of the workpiece.

Key Features and Advantages:

1. Čipová evakuace: The slanted bed design facilitates better chip evacuation, as chips naturally move away from the work area due to gravity, reducing the risk of chip buildup and improving machining efficiency.
2. Rigidity: The inclined bed provides enhanced rigidity, which results in better stability and accuracy during heavy-duty machining operations.
3. Accessibility: The slanted design provides easier access to the workpiece and cutting tools, allowing operators to observe and adjust the machining process more conveniently.
4. Improved Tool Life: Oblique lathes offer improved tool life by minimizing the chances of chip recutting, which can cause premature tool wear and reduce machining quality.
5. Vysoká přesnost: Despite their inclined design, oblique lathes maintain high levels of precision and accuracy in turning operations.
6. Všestrannost: These lathes are suitable for a variety of turning operations, from roughing to finishing, threading, and facing.
7. Účinnost: The combination of chip evacuation, rigidity, and accessibility contributes to increased machining efficiency and reduced downtime.
