A machining location for machining workpieces, comprising: a machine tool; an enclosure for said machine tool that encloses the entire machine tool within a predetermined space; workpiece storage within said predetermined space for storing workpieces at least prior to being worked on by said machine tool and for subjecting such workpieces when so stored to said machining environment to become oriented thereto. The machining location is mounted and supported to be separate from and independent of said machine tool so that vibrations are not transmitted from said enclosure to said machine tool. The machining location further comprises ambient environment controls for effecting control of at least the temperature of the air within said predetermined space.

Environmental conditioning of workpieces

A machine tool, particularly for grinding workpieces, has a single rotatable spindle (,) carrying a fixed cup-shaped inner grinding wheel (,) and an axially slidable cup-shaped outer grinding wheel (,). A T-shaped annular piston (,) engages in a recess with the spindle to form front and rear annular chambers to each of which hydraulic oil is alternately connectable. The piston has an outer part (,) on which is mounted the grinding wheel (,), being preferably the coarser of the two wheels for use in rough grinding. A tooth-shaped location device (,) at each side of the piston (,) engages with a respective device (,) on the spindle to prevent relative rotation of the wheel (,) and to provide a driving torque when it is advanced to its working position beyond the inner wheel (,).

Grinding machine spindle

A machine tool, comprising: a worktable assembly slidably carried by the machine frame for reciprocal movement along a work axis and which is configured to carry a workpiece. A worktool assembly is slidably carried by said machine frame for reciprocal movement along a worktool axis at a predetermined angle with respect to said work axis and so as to intersect same. A reference straight edge is carried by said worktable assembly and has a reference surface. Reference sensing means is carried by said machine frame for coaction with said reference straight edge reference surface, to measure reference spacing between said reference surface and said reference sensing means and to provide a reference output indictive of said reference spacing. Control means is provided to facilitate movement of said worktool towards and away from said work axis, which is responsive to said reference output to further facilitate worktool movement towards said work axis. The reference sensing means includes a fixed electrode that forms with said reference surface a capacitance gauge. The control means includes a look-up table storing information relative to initial dispositions of said reference surface and said reference sensing means, to provide an initial disposition output indicative thereof to further modify and facilitate worktool movement towards said work axis. The look-up table initial disposition output is indicative of the flatness of said reference surface.
