MULTI-EDGED MACHINING TOOL FOR POST-MACHINING OF BORES
The invention relates to a multi-edged machining tool for the post-machining or precision machining of bores, in particular to a reamer for machining deep bores or several axially interspaced bores of the same dimensions and quality, such as bores for receiving bearing bushes for a camshaft. The tool has at least one cutting insert (32) with a pre-determined nominal diameter measurement and with cutting edges that are distributed substantially uniformly around the periphery, in addition to a guide body assembly that is axially offset in relation to said edges. The aim of the invention is to improve the guide accuracy whilst providing greater flexibility during the adaptation of the tool to the machining problem at hand. To achieve this, the guide body assembly is an integral component of a substantially cylindrical guide body (36) that consists of a solid carbide. Said guide body forms at least n helical guide ribs (38) which are equidistant around the periphery and which have a nominal diameter measurement (D38) that is substantially smaller than the nominal diameter measurement (D32) of the cutting insert (32) by a value equating to double the dimension of the lubricant gap that is formed during the operation of the tool. Each guide rib (38) extends over an angle of contact or a central angle that is greater than 360°/n, where n ≥ 2.
Described is a multi-blade cutting and drilling finishing tool, in particular a reamer, for machining deep, especially stepped bores. Said tool comprises a set of blades having a predetermined nominal diameter and blades that are distributed in a substantially regular manner along the circumference. In order to make it easier to guide the tool along the central axis, a set of guiding strips (36) in the form of very accurately placed and preferably cylindrically ground cutting inserts (36-1 to 36-n) is located behind the set of blades (32) in the advancing direction. Each of said cutting inserts (36-1 to 36-n) is axially flush with the blades (32-1 to 32-n) of the adjacent set of blades (32) in the advancing direction of the tool and has a nominal diameter (D36) which is smaller than the nominal diameter of the set of blades (32) substantially by twice the size of a lubrication gap forming when the tool is used.
The invention relates to an advancement guide unit (5) for ensuring the straight-line motion of a manually guided machine tool (1), particularly a portable drill, in the direction of advancement thereof and is substantially composed of a support element (12) for support on a workpiece to be treated and a carriage (30) guided displaceably on the support element (12) relative thereto in the direction of advancement for supporting and guiding the machine tool (1). According to the invention, a damper (33) acting in the direction of advancement is disposed between the support element (12) and the carriage (30), said damper damping the initial stroke of the carriage (30) toward the support element (12) over a predefined initial stroke distance (y). In a refinement, the damper (33) is disposed between the support element (12) and carriage (30) such that the damping of the initial stroke of the carriage (30) only commences after a primary, undamped initial stroke of the carriage (30).
A milling tool (1) is disclosed, in particular, for rotational speeds of ≥ 10,000 rpm, with a base body (2), in which a channel arrangement is provided for introduction of coolant/lubricant to each blade of the milling tool (1). According to the invention, a central distributor (4) is arranged within the tool, from which a separate, individual coolant channel (7) runs to a coolant outlet opening (10) in front of each blade and each coolant channel (7) comes from the central distributor element (4) in an axial direction of the tool (1). The central distributor element (4) is furthermore a separate element.
The invention relates to a method for producing for example a cylindrical surface (Fig. 10) which has a suitable surface structure of a predetermined geometry for applying material by thermal spraying. According to said method, a geometrically defined groove structure (Fig. 10) of minor depth and width is introduced into the surface, for example cylindrical surface, of a substrate to be coated, which surface is premachined to size using a tool which is preferably a follow-on tool (12; Fig. 1), by gradually bringing a groove cross-section to a desired measure. In order for the surface to be producible in series with a constant quality, the groove structure is introduced by first machining a basic groove (52B; Fig. 10) having a groove root width which is smaller than the groove root width of the finished groove (52). The groove, for example at least one flank (52-1 & 52-2) of the basic groove, is then machined in a non-cutting or cutting manner to produce an undercut groove profile, the groove structure produced by introduction being deformed in such a manner that the groove openings are made narrower by upsetting deformation.
