Slant bed CNC lathe tilt meaning

The two guide rail of the slant bed CNC lathes, fellowship with ground plane, the plane into a slope, Angle has 30 °, 45 °, 60 °, 75 °. The slant bed CNC lathe bed is a right triangle. Obviously, in the case of the same width of guide rail, slant bed X to drag board is taking longer than flat bed, the practical significance of the application on the lathe is can arrange more digits. Slant bed CNC lathe cross-sectional area than with the specifications of the flat bed is big, the stronger resistance to bending and torsional ability.

1。 Good stability

too much need to machining parts do you usually use slant bed or flat bed inclined guide rail machine, because of the large machine tool parts is very big also, corresponding knife tower parts, in particular, using inclined guide is mainly in order to overcome the gravity has better stability to improve the accuracy of machine tool, in some bad environment can reflect the superiority of inclined body machine.

2。 To improve space utilization

inclined body machine can effective use of space, greatly reduced the surface covering location of machine tool.

3。 Facilitate clearance

sloping guideway also facilitate the iron concentration in the chip removal machine is easy to realize automatic chip removal. Cutting down the iron filings with high quantity of heat, accumulate in the guide will make guide heat deformation, make the change work precision, can lead to artifacts in the process of mass automatic processing of the batch scrap.

slant bed CNC lathe maintenance analysis as follows:

in order to ensure the accuracy of the slant bed CNC lathe work, prolong service life, must be for personal use slant bed CNC lathe for reasonable maintenance work. The stand or fall of lathe maintenance, directly affect the workpiece processing quality and production efficiency. When machine run after 500 h, require maintenance. Slant bed CNC lathe maintenance work is given priority to with operators, maintenance workers to cooperate. Maintenance, must cut off the electricity first agent and maintenance according to maintenance content and requirements.

1) With bed, bed, lead screw, stent related parts such as precision, carefully investigates the structure and machining precision of optimization, and increase the assembly control, so that higher accuracy and reliability of the whole machine is greatly increased, repeated positioning precision is increased by 30%, part of the performance index reach the standard precision machine tools.

2) , lathe to provide sustained and effective guide rail and ball screw automatic lubrication, automatic chip removal and forced cooling, to ensure long uninterrupted work, machine tool spindle speed 6000 r/min, the fast speed of 24 m/min, the adjacent position of tool change time is only 0. 4 s, the better combination of various indicators and reliable operation, can make the machine tool processing efficiency more than 10%.

3) With a tilt of lathe bed CNC lathes have been completely closed and protected, to avoid the iron filings and coolant leakage. Various extreme protection and the agency system combined self-diagnosis tips and warnings, can ensure that the lathe run continuously without downtime, especially suitable for the production line has 24 hours work system.

how to reduce the friction CNC lathe bed of the tilt error?

1。 Reduce friction drive system

use rolling guide, hydrostatic guideway and hydrostatic guideway air, to reduce the friction system, reduce the difference between the kinetic and static friction, and improve the dynamic performance of feed system. But using high-performance guide will greatly increase the cost of the machine tool.

2。 Improve the rigidity of servo drive system

by raising the servo drive system of the position loop, speed loop and current loop stiffness, during friction error timely adjust appropriately small error signal to the motor drive current. Easy to cause the system oscillation but high stiffness.

reduction of each control loop servo drive control cycle also helps to improve the response speed of system. However, reduce the control cycle need higher hardware performance.

oblique CNC lathe bed USES 45 ° inclined bed layout structure, hardening guide rail, cast iron is a kind of two axes linkage, high speed, high precision, high performance precision CNC lathe. Applicable to the main characteristics of the mechanical processing industry, the rotation of the complex shape parts suitable for automatic, precision machining, especially suitable for large, in batch and many varieties of spinning production. This product has high rigidity, good accuracy and safety.
