A multifunction spindle for a machine tool for machining workpieces has a spindle housing, rotational drive, and tool-holding unit. The tool-holding unit is disposed within the spindle housing and pivots relative to the spindle housing about an axis perpendicular to the axis of rotation. The spindle has two measurement heads connected to a transmission path for measuring position angle and enhances positioning accuracy.

A rotary table (1) includes a base body (10), a worm wheel (21), an inner ring (22), a plurality of rolling elements, and a worm screw unit (30). The worm screw unit (32) includes a worm screw (31) and a worm screw housing (32). The worm screw housing (32) has an opposing surface that faces an outer circumferential surface (21B) of the worm wheel (21). The worm screw housing (32) includes a flange portion (325) that protrudes from the opposing surface and covers a side face (215A) that, of the first gear (215) facing the opposing surface, is on the opposite side from the base body (10) in the axial direction of the worm wheel (21).

A sliding compound miter saw slide device allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The sliding saw slide device integrates an adjustment or alignment mechanism configured to move an upper base portion of the saw base relative to a lower base portion of the saw base. In addition, a sliding saw stand allows a user to easily and accurately move a saw for proper alignment with a cutting material or workpiece. The sliding saw stand integrates an adjustment or alignment mechanism configured to move an upper miter saw mount member/plate relative to the saw stand base/base frame.

A transfer machine for machining operations includes a frame, a rotary table with a rotary feeding movement relative to a machine axis, a plurality of workpiece-holder members associated with the rotary table and spaced by a working radius (r) from the machine axis, and a plurality of workstations accessible by the workpiece-holder members as a result of the feeding movement of the table. The transfer machine further includes at least one rotary unit able to rotate a workpiece-holder member about a respective axis and relative to the table, wherein the rotary unit includes a motor assembly located in the machine base at a distance (d) from the machine axis which is less than the working radius (r).

There is provided a rotary table device including: a rotary table; a center shaft erected toward the rotary table; a housing including an inner peripheral surface having a circular cross section over a predetermined range along a rotation axis; a center sleeve including an outer peripheral surface having a circular cross section corresponding to the inner peripheral surface, and the outer peripheral surface being concentric with the inner peripheral surface; a plurality of recesses formed in at least one of the inner circumferential surface and the outer circumferential surface; a plurality of O-rings disposed to be sandwiched between the inner peripheral surface and the outer peripheral surface; an in-housing fluid flow path formed inside the housing; and a plurality of in-sleeve fluid flow paths formed inside the center sleeve.

A rotary seat including a base includes an outer surface, and a composite material layer attached to at least a part of the outer surface. The base also includes a recess for accommodating a turntable and including a first opening on the outer surface. The material of the composite material layer includes fibers and a resin. Therefore, the rotary seat may be more lightweight. A rotary table is also provided and includes the rotary seat, a driving device which drives the rotary seat to rotate, and a turntable which is rotatably disposed in the recess of the base.
