SCOPE 1.1 Modification: This section applies to planers. NOTE: For Planers with cutting width more than 150 IRR o
16、ther requirements may be necessary. 2. DEFINITIONS 2.2 8. Addition: The rated no-load speed is the speed obtained when the planer has been running idle for 10 min. 18. Modification: Normal load denotes the load obtained when the planer is operated continuously the load being such that the input, in
17、Watts, is equal to rated input. Addition : For tests to be made under normal load the spindle of the motor may be loaded by means of a brake. Addition : 29. Cuttinu head denotes the assembly of blades, drums, blade fixing elements, relevant screws and spindle, the whole being ready for working. 7. M
18、ARKING 7.1 Addition: Planers shall be marked with: - Rated no-load speed, in revolutions per minute, of the - Indication of direction of rotation: cutting head, marked on the nameplate The direction of rotation of the cutting head shall be clearly indicated by an arrow, raised or sunk, or by any oth
19、er means no less visible and indelible. Page 4 HD 400.3M S2:1992 7.13 10.1 10.2 11.1 ” Addition : The planer shall be provided with an instruction sheet in which the substance of the following information shall be contained: - Instruction for replacement of the blades (adjustment) - The necessity of
20、 the use of sharp blades - Wait for complete run-down before putting the tool - Types of cutting heads which can be used. aside Moreover, if a planer is suitable for, and used in, an inverted position as a stationary machine, the instruction sheet shall contain also the following information: - Use
21、of the movable guard - Machining of small work-pieces with push stick - Disconnection of the tool from mains supply before fitting a planer to a stand for use in the inverted posit ion - Use of the switch. Where applicable the instruction sheet shall state how to connect the external suction equipme
22、nt. 10. INPUT AND CURRENT Modification: This test is not made. Addition : Compliance is checked by measuring the current after the planer has been operating for 10 min. 11. HEATING Addition: The planer is operated for 30 mina 18. MECHANICAL HAZARDS Addition: 18.3 to 18.6 Reserved. 3404583 0032598 O
23、18.7 18.8 18.9 Page 5 HD 400.3M S2:1992 Cutting heads must have a circular section along the whole cutting width except for the blades, the fixing screws and full chip clearance area. The blades shall not project by more than 1.1 mm radially beyond the drum (as per dimension “a“ in figure M1). Compl
24、iance is checked by measurement. The maximum chip clearance distance, in mm, to be provided is given by the formula: For d 80 mm : S max = 0.1 x d + 18 Compliance is checked by measurement. 18.10 The distance b (see figure M1) between the rotating circle of the cutting edges and the lips of the adju
25、stable shoe shall not exceed 5 mm, from zero to the maximum adjustable planing depth. Compliance is checked by measurement and inspection. Chip clearance distance Figure Hl Page 6 HD 400.3M S2:1992 3404583 0032599 2 18.11 The blades shall be fixed to the drum in such a way that friction alone is not
26、 relied upon to prevent ejection of the blades. The clamping screws if any shall engage for a minimum of five full threads when the blades are fitted to a steel drum. When the drum is made of a material other than steel the clamping arrangement shall have the same degree of strength etc. as that pro
27、vided by the requirements for the clamping screws for steel drums. Compliance is checked by measurement and inspection. 18.12 The lock system between drum and blade shall be so designed and made that replacement and adjustment of the blades does not compromise safety. Compliance is checked by inspec
28、tion and manual test. 18.13 The clamping screws or the blade fixing elements used to clamp the blades on the drum shall be made of steel with a hardness of at least 20 HRC and a stensile strength of at least 800 N/mmZ. The clamping screws or the bolts shall not project above the max. diameter of the
29、 drum. 18.14 It shall not be possible to touch rotating parts from the sides. Compliance is checked by the following test: The planer with the shoe is placed resting on a flat surface and accessibility of rotating parts is checked by means of the test probe as shown in figure M2. 18.15 Planers with
30、rabbeting facilities shall be provided with a guard that avoids inadvertent contact with the blades on the side. Compliance is checked by inspection and applying the test probe of figure M2 without any force. Handle section Dimensions in mm Figure H2 3404583 O032600 5 Page 7 HD 400.3M S2:1992 18.16
31、It shall not be possible to touch the blades through the chip ejection opening. Compliance is checked by testing all apertures for chip ejection with the test probe of figure M2. It shall not be possible to touch the blades fo the cutting head at any angle of the probe. 18.17 If according to the man
32、ufacturers instructions a planer is suitable for use in an inverted position with an appropriate stand an integrated or additional guard shall be provided, with the stand or with the planer, which covers the cutting head when the planer is not in use. If a parallel guide is provided its guiding and
33、top surface shall have no openings or projections. Openings the maximum dimension of which is 10 mm are disregarded. The guard and the parallel guide shall be so designed that for any cutting width the unused part of the cutting head is covered. The guard provided shall return automatically to the c
34、losed position at the end of the planing operation. Planers provided with an integrated non detachable non-lockable guard which automatically closes, state of rest the cutting head, e.g., concentrically and over the whole width, do not need in stationary operation an additional guard to the above de
35、scribed parallel guide. Examples of parallel guide and guards are given in figure M3. and in the Any contact between steel and other hard material guards with the blades is to be avoided. If the guard or parallel guide are designed in such a way that their contact with the cutting head is not avoide
36、d, they shall be made of soft material (e.9. wood, plastic material, aluminium). Compliance is checked by inspection. W 3404583 0032bOL i I L ._ . Page 8 HD 400.3M S2:1992 Parallel guide Figure X3 20. CONSTRUCTION 20.11 Replacement: Planers shall be fitted with a mains switch such that the motor is
37、switched off automatically as soon as the actuating member of the switch is released. This swith shall have no arrangement to lock it in the “on“ position. When planers which may be used with an appropriate stand in the inverted position are mounted in the stand, means may be provided with the stand to hold the mains switch in the “on“ position. It shall be possible to switch off easily by the user. Compliance is checked by inspection and by manual test. I 2 O. 22. Addition : Planers are considered tools for which provisions of Part 1 regarding dust collection apply.
