Abstract
A machine tool includes a table slidably supported on a carrier and movable relative to the carrier by a driving device, a telescopic covering device having two or more cover members telescopically slide relative to each other in response to a sliding movement between the table and the carrier. A connecting device includes a tubular member attached to the inner cover member, and a rod attached to the carrier and movable into and out of the tubular member when the inner cover member is moved relative to the carrier for guiding the table to smoothly slide relative to the carrier.

A machine tool comprising:
- a carrier,
- a table slidably supported on said carrier and movable along and relative to said carrier,
- means for driving said table to move relative to said carrier,
- a telescopic covering device including a first cover member attached to said table and moved in concert with said table, a second cover member to be movably coupled to said carrier, and at least one third cover member telescopically coupled between said first and said second cover members for allowing said first and said second and said at least one third cover members to telescopically slide relative to each other in response to a sliding movement between said table and said carrier,
- a connecting device including a tubular member attached to said second cover member and moved in concert with said second cover member, a rod attached to said carrier and slidably engaged into said tubular member and movable into and out of said tubular member when said second cover member is moved relative to said carrier, and
- means for biasing said table to move relative to said carrier in order to force said tubular member to engage onto said rod.
