Voorbeeldzinnen

1. Wheel-dressing systems in grinding machines;
2. The c-axis is used to maintain the grinding wheel normal to the work surface; or
3. Jig grinders with axes limited to x, y, c and a where c axis is used to maintain the grinding wheel normal to the work surface, and the a axis is configured to grind barrel cams;
4. For the purposes of 2B, the number of axes which can be co-ordinated simultaneosly for "contouring control" is the number of axes which affect relative movement between any one workpiece and a tool, cutting head or grinding wheel which is cutting or removing material from the workpiece.
5. For the purposes of 2B, the number of axes which can be co-ordinated simultaneosly for "contouring control" is the number of axes which affect relative movement between any one workpiece and a tool, cutting head or grinding wheel which is cutting or removing material from the workpiece. This does not include any additional axes which affect other relative movement within the machine.
6. Cylindrical external, internal, and external-internal grinding machines having all the following characteristics: a. Limited to cylindrical grinding; and b. Limited to a maximum workpiece capacity of 150 mm outside diameter or length. 2. Machines designed specifically as jig grinders having any of the following characteristics: a. The c-axis is used to maintain the grinding wheel normal to the work surface; or b. The a-axis is configured to grind barrel cams. 3. Surface grinders. d. Electrical discharge machines (EDM) of the non-wire type which have two or more rotary axes which can be coordinated simultaneously for "contouring control"; e. Machine tools for removing metals, ceramics or "composites" having all of the following characteristics:
7. Overall positioning accuracy on the x-axis more (worse) than 30 μm. b. Machine tools for grinding, having any of the following characteristics: 1. Positioning accuracies with "all compensations available" equal to or less (better) than 4 μm according to ISO 230/2 (1988) [1] Manufacturers calculating positioning accuracy in accordance with ISO 230/2 (1997) should consult the competent authorities of the Member State in which they are established. or national equivalents along any linear axis; or 2. Two or more contouring rotary axes. Note: 2B201.b. does not control the following grinding machines: a. Cylindrical external, internal, and external-internal grinding machines having all of the following characteristics: 1. Limited to cylindrical grinding; 2. A maximum workpiece outside diameter or length of 150 mm; 3. Not more than two axes that can be coordinated simultaneously for "contouring control"; and 4. No contouring c axis; b. Jig grinders with axes limited to x, y, c and a where c axis is used to maintain the grinding wheel normal to the work surface, and the a axis is configured to grind barrel cams; c. Tool or cutter grinding machines with "software" specially designed for the production of tools or cutters; or d. Crankshaft or camshaft grinding machines. 2B204 "Isostatic presses", other than those specified in 2B004 or 2B104, and related equipment, as follows: a. "Isostatic presses" having both of the following characteristics: 1. Capable of achieving a maximum working pressure of 69 MPa or greater; and 2. A chamber cavity with an inside diameter in excess of 152 mm; b. Dies, moulds and controls, specially designed for "isostatic presses" specified in 2B204.a. Technical Note:
