Aluminum Frames, As fixed length frames are frames that are cut by the customer, the exact length cannot be specified.
Alterations of Aluminum Frames (Specified Length Only, Fixed Length Not Possible)
[ ! ]Aluminum Frames, By using the various alterations listed below, MISUMI's specified length aluminum frames can be assembled with greaterflexibility.Some frames cannot be applied depending on the type and size. Please check the price list on each alteration page tosee if it is applicable.
Items marked with "-" in the price list cannot be applied.
| classification | Additional Work name | Alteration code example | How to Use | Content |
|---|---|---|---|---|
| End face tapping | End face tap (center hole) | LTP/RTP/TPW LHP/RHP/HPW | ![]() | The frame is tapped. LTP/RTP/TPW: M12 depth 36mm LHP/RHP/HPW: M8 depth 15mm (with helical insert inserted) This processing is required for blind joints ( screw joints / simple joints ). |
| Change cutting method | High-precision cutting | SC | ![]() | Aluminum Frames, The tolerance of the overall length L has been changed from L±0.5 to L±0.2, allowing for high-precision cutting. *Only applicable to L≦1500 |
| 45 degree cut | L□T45 R□T45 | ![]() | Aluminum Frames, The cut is made at a 45-degree angle. 45-degree cuts cannot be specified in the same direction with other alterations. Example: HFS6-3030-500- L TP- LAT45 ⇒ ✖ (alterations in the same direction (left)) HFS6-3030-500- L TP- RAT45 ⇒ 〇 (separate alterations on left and right) [ ! ]If you would like to cut at an angle other than 45 degrees, please contact our catalog non-standard product service . | |
| Wrench Drilling | Fixed position wrench hole | LCH/LCV/LCP RCH/RCV/RCP | ![]() | Aluminum Frames, This additional processing is required to drill a wrench hole (φ8) in accordance with the position of the tap onthe end face of the mating frame when fastening a blind joint that assembles frames into an L shape. Blind joints that require this processing ( screw joints / single joints / tapping joints ) |
Hole position shifted by the thickness of the frame cap | FL FR | ![]() | Aluminum Frames, The hole position for the additional fixed position wrench hole is moved by the thickness of the frame cap (3mm). This prevents the frame cap from protruding when assembled at a corner. | |
| Wrench holes at specified positions | AH/BH/CH/DH/EH AV/BV/CV/DV/EV AP/BP/CP/DP/EP | ![]() | Aluminum Frames, This is an additional process to drill a wrench hole (φ8) at any position. It can be used when fastening blindjoints at locations other than the frame end. ・ Up to five holes can be drilled in each of the horizontal, vertical, and cross directions. [!] If you require six or more wrench holes, please contact our catalog non-standard product service . | |
| Counterbore Drilling | Specified position counterbored hole | Z12-YA○○ | ![]() | Aluminum Frames, This is an additional process to drill a counterbore hole (select from Z6, Z8, or Z12) at any position. Z6: Through hole φ6.5, counterbore φ11, Z8: Through hole φ9, counterbore φ14, Z12: Through hole φ13,counterbore φ19 . Up to five holes can be drilled in one direction. For frames with multiple rows of grooves on one surface, counterbore holes will be machined in all grooves. [ ! ]Aluminum Frames, If you require more than six counterbore holes or to change the direction of the counterbore holes, please contact our non-standard product service . |
| Drilling holes specifically for blind joints | D hole | LDH RDH | ![]() | Drill the holes required for fastening a single joint. ( Single joint ) |
| S hole | LSH RSH | ![]() | Drills holes required for fastening first-in-place double joints ( first-in-place double joints ) . | |
| M hole | LMH/LMV RMH/RMV | ![]() | Drills holes required for connecting post-assembly double joints and center joints. ( Post-assembly double joints / center joints ) | |
| L hole | JLP○○-H△ KLP○○-H△ | ![]() | Drill holes required for connecting parallel joints. ( Parallel joints ) | |
| Other processing | C-chamfered end | CW | ![]() | Aluminum Frames, The outer periphery of the frame end face is chamfered. |
| Sticking stickers | ZZZ | ![]() | Aluminum Frames, A sticker printed with the catalog number etc. is attached to the aluminum frame. There are restrictions on the number of characters etc., but it is also possible to print the customer's serialnumber and unit number. |

- How to think about the allowable guideline load (deflection) for Aluminum Frames
[!]The allowable guideline load is the load that causes the frame to deflect within 1 mm per 1000 mm of length.
Deflection exceeding this will not cause damage, but it should be considered the maximum practical deflection.(The allowable guideline deflection is proportional to the length. For example, 500 mm = 0.5 mm, 2000 mm = 2 mm.)Please refer to
the Aluminum Frames strength guideline table or the simplified deflection calculation table/deflection calculation formula for your reference.
