A spindle apparatus for use at a machine tool, having: an assembly including a workpiece spindle to receive an elongated workpiece and a motor for driving spindle rotation of the workpiece spindle about a spindle axis; a rotary guide-bush assembly being axially arranged with the workpiece spindle with respect to the spindle axis, the rotary guide-bush assembly receiving the elongated workpiece supported at the rotary guide-bush assembly to rotate about the spindle axis enabling movement of the elongated workpiece; wherein the rotary guide-bush assembly includes a portion to clamp the elongated workpiece, received in the rotary guide-bush and in the workpiece spindle, to transfer driving torque applied from the spindle motor during a driven acceleration of the rotation through the clamped elongated workpiece for rotation of the rotary guide-bush synchronized with the driven acceleration of the rotation of the workpiece spindle.

A spindle apparatus for use at a machine tool, in particular a lathe, has: a spindle assembly including a workpiece spindle to receive an elongated workpiece and a spindle motor for driving spindle rotation; and a rotary guide-bush assembly axially arranged with the workpiece spindle, the rotary guide-bush assembly including a rotary guide-bush to receive the elongated workpiece and supported at the rotary guide-bush assembly to rotate with the elongated workpiece received in the workpiece spindle about the axis while enabling a movement of the elongated workpiece in the axial direction. The spindle and rotary guide-bush assemblies connect to each other by a torque transferring connection, between the spindle and rotary guide-bush assemblies along the axis to transfer driving torque during acceleration or deceleration of the spindle rotation driven by the spindle motor to the rotary guide-bush of the rotary guide-bush assembly.

A work-machine splash guard for enclosing a space for machining a workpiece, and preventing the spraying of chips and machining fluid, is equipped with: a front-surface door for opening and closing in the horizontal direction via an arc-shaped movement, and positioned on the front-surface side of the work machine; a side-surface door for opening and closing by performing an arc-shaped movement that is concentric with the front-surface door, and overlapping with the front-surface door; and door-locking switches for selectively allowing the opening/closing of the front-surface door and the side-surface door according to an opening/closing pattern.

A deflector apparatus catches debris and deflects coolant spray in a coolant collection area of machine tools having an extended drawtube or bar feed area such as CNC lathes. The deflector apparatus encloses the coolant collection area by covering the opening or access to the area with a door and attached basket. The basket extends into the coolant collection area at an incline relative to the door and interrupts coolant and debris entering the coolant collection area from the drawtube, causing the debris to collect within the basket and allowing coolant to filter through a grate positioned on a lower surface of the basket. A flange with an outer seal extends along part of the lower edge of the door to create a seal between the door and the opening to the coolant collection area. Additional features include a locking mechanism, handle, and reinforcement plate.
