bore for direct mounting on spindle nose of a milling cutter
The inventive machine tool (10) has a machine frame (59) and a spindle nose (12) arranged on said frame.
The collet (40) or clamping tool is attachable to the spindle nose of the machine tool and is drawn into the bore of the clamping portion (14).
The collet (40) or clamping tool is attachable to the spindle nose of the machine tool and is drawn into the bore (15) of the clamping portion (14).
A wheel for heavy machinery comprises a tire (1), a rim (2), a batten (3), a spindle nose (4) and a fastening member (5).
The inner peripheral surface relative to the pin nose (30) of a box member (1) has a tapered surface (20) that interferes with the pin nose outer peripheral surface (30) when connecting with the pin member (3).
The counter spindle’s nose is also larger: With A2-5, the counter spindle can be used to remove bar stock parts with a diameter of up to 45 mm.
Specifically, the pin nose outer peripheral surface (30) forms a convex curve on the outside thereof in a cross section in the axial direction.
The changing device (15) grips the tool shanks laterally.
The tool shanks are taken and transferred to the changing device (15) by a transport device (24), which seizes the tool shanks from above.
For replacing the tool shank (SK1) by a new one (SK2), there is a changing device (15) having a changer arm (16) pivotable through 90° about a vertical shaft (37).
On the changer arm (16) are fitted two securing couplers (17, 18), one above the other, each of which can support a tool shank (SK1, SK2).
The invention relates to a spindle head for a universal milling machine.
Said head comprises a housing (12) that is rotatably mounted on a machine part (10) and a directly driven working spindle (14) that is positioned in the housing parallel to the axis.
A ram (14) for transmitting axial forces between the coupling sleeve (7) and the spindle head (8) is placed between both bearing elements (12, 13).
The spindle head (17) is mounted pivotably about a vertical pivot axis (19) such that the tools (22) mounted in the spindle head (17) extend horizontally.
The machine tool has a table (10) with a vertically movable slide (12) which bears a tool shank (SK1) and hence performs the machining.
When the changer arm (16) is pivoted through 90°, the tool shank is pivoted in front of the table (10) so that it can be accepted by the vertical slide (12).
The rotating joint (4) has a coupling sleeve (7), which is rotationally fixed to the roll (6), and has a second spindle head (8), which is rotationally connected to the second shaft (5).
