A machine tool includes a table, a main shaft, and an electric heating piece. The table includes an upright post and a main shaft support element connected to the upright post. The main shaft is rotatably disposed at the main shaft support element of the table. The electric heating piece is disposed at the main shaft support element of the table and positioned on a side of the main shaft, wherein the side of the main shaft manifests a lower thermal deformation level. The regulation of the electric heating piece minimizes the nonlinear thermal deformation of the main shaft, thereby enhancing processing precision.

A cooling method and cooling apparatus which can reduce thermal deformation of a mobile body of a machine tool is provided. On the front of a column (1), a pair of upper and lower guides (3) is formed, and saddle (7) is suspended on guides (3), saddle (7) being movable left and right. Guiding surface (5) of guide (3) and sliding surface (9) of saddle (7) are slip surface and are in contact with each other. Sliding surfaces (9a, 9b, 9d, 9e) which generate a large amount of heat and need to be cooled are identified in advance by simulation. Fluid pipelines (25) for cooling the identified portions generating higher heat are formed, and a coolant liquid is circulated by being passed from portion (9a) generating less heat toward portion (9e) generating higher heat.

The invention relates to a liquid cooling system for machine components of production machines of the tobacco-processing industry. The object of the described cooling system is to improve the conveyance of liquid, both in terms of structure and function. This object is accomplished by dividing the liquid cooling system, which is embodied as a closed system, into at least two liquid loops (13, 17). The advantage that can be attained with the new liquid cooling system is that the liquid loops can be adapted to one another such that the temperature and output of the consumers match. The pipe cross-sections and pumps can therefore be kept small.

A cooling system of machine tool body casting includes a body casting, a cooling device, and a fan. The body casting is provided with an inner space, an inlet end, and an outlet end. The inlet end and the outlet end are connected with the inner space. The cooling device is disposed at the inlet end. The fan is disposed on one side of the cooling device for inputting external air, such that the external air is input into the inner space and discharged from the outlet end. Therefore, the fan triggers the cold air to flow in the inner space for cooling down the heat of the body casting.

Provided is a machine tool having functional components that produce heat during operation and which are arranged on a machine frame having cavity structures that form a circulation circuit in which a coolant is circulated inside the machine frame. The machine frame has first areas where the heat-generating functional components are arranged, and second areas spaced apart from the first areas. The heat input in the second areas, which is produced by the functional components, is smaller than that in the first areas. The cavity structures have first sections which are arranged in the first areas and second sections that are arranged in the second areas, and therefore, when the coolant is circulated from the first sections to the second sections, the heat supplied by the functional components is dissipated into the second areas so as to effect a temperature compensation between the first and second areas.

A machine tool includes X-axis, Y-axis, and Z-axis moving units for producing relative movements between a tool and a workpiece; a C-axis drive unit for rotating the workpiece about a C-axis parallel to the Z-axis; and a B-axis turning unit for turning the tool about a B-axis parallel to the Y-axis. The tool is disposed in such a manner that a machining point of the tool coincides with the B-axis. The moving units, the drive unit, and the turning unit are controlled in such a manner that a work point of the workpiece coincides with the machining point of the tool. The bed is formed through casting and has a hollow structure and a hole as cast; and a cover is provided to cover the hole as cast in order to close the interior of the bed.

An automated planer machine for planing a piece of lumber. The planer machine has a feed table for slidably receiving the bottom surface of the piece of lumber along a traveling course. One or more planing heads extend on sides of the traveling course to plane the surfaces of the piece of lumber. A linebar laterally guides the piece of lumber. Feed rolls along the traveling course move the piece of lumber. Positioning devices responsive to respective control signals are provided for adjusting a height of the feed table and planing levels of the planing heads as much when the planer machine is idle as during operation. Position encoders coupled to the feed table and the planing heads produce positional signals usable to accurately position them using the positioning devices.
