The following operations in the manufacture of tungsten carbide tipped drilling equipment:
RATE AA (n.e.s.)
| 1. | General supervisory work, including setting up of production machines (at least one supervisor must be employed in each establishment and be in charge of operations on each shift). |
| 2. | Machine tool grinding for production machines. |
RATE B
| 1. | Heat treatment — supervisory work. |
RATE C
| 1. | Supervising forging operations, including setting up (at least one supervisor to be employed in each establishment on each shift) (n.e.s.): |
First six months of experience
|
Rate D
|
Thereafter
|
Rate C
|
RATE D
| 1. | Metal drill sharpening by machine. |
| 2. | Machining on repetition work by means of fixtures and/or jigs and/or stops where the work cycle is manually operated (excluding setting up but including the use of fixed gauges) (n.e.s.). |
RATE F
| 1. | *Repetition operation of or attending semi-automatic machines where the work cycle is power-driven and the end point is controlled by automatically operating stops (excluding setting up). |
*‘Semi-automatic machine’ is a machine on which it is not necessary to centralise or true the work by hand and where the manual operations are limited to loading the work piece into the chuck or holding device of the machine, setting the machine in motion, advancing or retracting tools before and after the power cycle takes over and stopping and unloading the machine.
| 2. | Repetition production machining of bar on capstan lathes to stops where the work piece is held by devices not necessitating any centralising or trueing, (excluding setting up). (This operation is limited to a machine not exceeding a 52 mm nominal bore diameter.) |
RATE G
| 1. | Bonding of tip to shank by pre-set static heating unit. |
| 2. | Operating butt and/or spot welding machine. |
| 3. | Operating forging machine. |
| 4. | Operating machine set up for and performing one operation (excluding setting up). |
| 5. | Repetition grinding off of excess brazing from drill points to fixed gauges. |
| 6. | Removing and/or replacing forging dies, excluding setting up, under the instruction of a Rate A to C employee. |
| 7. | Repetition drilling of the flush or water hole on angle, horizontal or pedestal machines. |
| 8. | Repetition drilling and/or countersinking and/or reaming by non-adjustable reamers to fixtures and/or jigs and/or templets. |
RATE H
| 1. | *Attending fully-automatic machine, including random checking with fixed gauges. |
*For the purposes of the above, ‘fully-automatic machine’ is a bar-fed machine or a machine fitted with an automatic chucking device (i.e. magazine and/or table and/or mechanical arm fed) and where the manual operations are limited to setting the machine in motion and stopping and feeding a new bar into the machine or loading the magazine, as the case may be.
| 2. | Dressing and/or deburring by hand and/or by grinding and/or by portable power tool. |
| 3. | Operating power saw for repetitive cutting off to stops and/or length gauges (excluding setting of stops), other than tool room. |
| 4. | Repetition threading and/or tapping by machine. |
| 5. | Application of anti-corrosive and/or protective coatings. |
| 6. | Heat treatment under instruction of a Rate B employee. |
| 7. | Loading and/or unloading of furnaces. |
| 9. | Metal buffing and/or polishing and/or cleaning. |
| 10. | Operating hand portable and/or pedestal grinding machine where the operator is not required to grind to marks and/or and/or gauges and/or sizes. |
| 11. | Operating sand and/or shot blasting machine. |
| 12. | Repetition inserting of tips into head, prior to bonding. |
| 13. | Repetition rough straightening by machine or by hand and/or rough checking. |
| 14. | Spray and/or dip painting. |
