Abstract
A machine tool comprising tool spindle (12) having a chuck (26) and a spindle motor, in which the chuck (26) can be actuated for the purpose of receiving and releasing a tool, a sealing air channel (40) is provided which extends at least partially radially outside the chuck (26). The sealing air channel (40) terminates in or at a protective cap (34).
Claims25
A machine tool comprising
- a tool spindle (12) having a chuck (26) and a spindle motor,
- a sealing air channel (40) which extends at least partially radially outside the chuck (26),
- wherein the chuck (26) can be actuated for receiving and releasing a tool, and
- wherein the sealing air channel (40) terminates in or at a protective cap (34).
1 more element
A machine tool comprising
- a spindle which is intended for clamping a tool (14), and
- a spindle housing (16), on which the spindle is mounted, which spindle protrudes from the spindle housing (16) at a front end of the spindle housing (16),
- wherein the spindle housing (16) forms, at its front end, a protective cap (34) towards the spindle, which protective cap (34) has, at the protective cap's front end (58), a diameter, which is smaller than a diameter at the protective cap's other, rearward end (54), and forms, at the front end (58), an annular gap (46) with a rotating part of the machine tool or the tool (14), at which annular gap (46), a positive pressure space supplied with air, terminates.
A protective cap for a machine tool comprising a spindle, a spindle housing (16) and a tool (14),
- wherein the protective cap (34), which is mounted or fastened on a fixed part of the machine tool (10) has, at a front end (58), a diameter smaller than a diameter at an other, rearward end (54) and has, at the front end (58), a slender shape in comparison to the other rearward end (54), said slender shape approximating the end-side inner diameter (60) at the front end (58).
