LX-FDLK-SD50-AH Quick-Change Force-Control Belt Grinder
LX-FDLK-SD50-AH: compare the 1 kW drive, 7.2 kg unit boundary and 14.8 kg force-control assembly against the ordered mounting and a measured process trial.
Manufacturer data with selection guidance for buyers.
Manufacturer data
Published specifications
LX-FDLK-SD50-AH is a Langxin finishing tool with 1 kW published motor power and 3.2 Nm rated torque. Its sheet distinguishes 7.2 kg unit mass from 14.8 kg with force control. Review the mounting, drive, consumable replacement, full wrist-load boundary and a measured trial; no finished-process result is guaranteed.

Review the robot exchange interface separately from belt replacement
LX-FDLK-SD50-AH is described as the belt grinder combined with the LX-FDLK-300H force-control system through a robot quick-change interface, allowing a cell to exchange this tool for other tools. The sheet lists 7.2 kg for the unit with the quick-change device and 14.8 kg for the assembly with force control. The direct-mounted A counterpart lists 6.4 and 12.8 kg respectively. Those differences are meaningful for mounting and wrist-load review, but the publication does not explain every component contributing to the assembly difference. Obtain the ordered bill of materials instead of attributing the entire change to one coupling.
Record scope: [S1]
Read the tool and assembly as different boundaries
| Published item / decision | How to use it | Limit to confirm |
|---|---|---|
| Motor ratings | 1 kW; 3,000 r/min; 220 V; 3.2 Nm rated torque | Same published motor figures as A; interface flexibility is not extra cutting power. |
| Belt and air supply | 50 × 450 mm belt; 0.6MP air notation | Confirm pressure unit, regulated supply and required flow; no belt surface speed inferred. |
| Tool exchange | Robot quick-change connection with LX-FDLK-300H | Agree on mating halves, service couplings, lock confirmation and a safe dock sequence. |
| Mass boundary | 7.2 kg unit; 14.8 kg with force control | With the quick-change device; add adapters, abrasives and services only if outside the signed mass boundary. |
| Two replacement operations | Robot tool exchange and abrasive-belt replacement | They need different hardware and acceptance checks; neither implies the other is automatic. |

Resolve the ordered configuration
Record scope: [S1]
Build a measured acceptance trial
- First prove the belt process on representative parts using the agreed belt, force and drive settings. Establish accepted edge or surface measurements independently of exchange speed.
- Exchange between the belt tool and every intended neighbouring tool. Verify tool identity, mechanical locking and correct service connection before motion or rotation.
- Repeat after a worn belt is replaced and after the AH tool is docked and picked up. Check tracking, contact position and measured finish rather than only a successful pickup signal.
- Include an interrupted exchange and failed lock confirmation in the agreed supplier acceptance procedure. Record the safe stop, recovery responsibility and restart checks.

Investigate symptoms without inventing a cause
| Published item / decision | How to use it | Limit to confirm |
|---|---|---|
| Finish shifts after docking | Compare interface seating, repeatable contact position and tool calibration. | The source does not publish an interface repeatability guarantee. |
| Tool changes but belt replacement remains manual | Check the two separate hardware scopes. | AH identifies a robot exchange interface, not an included automatic belt magazine. |
| Robot load margin disappears | Reconcile the 14.8 kg assembly boundary with adapters, services and moments. | The 7.2 kg unit alone understates the described force-control assembly. |

Freeze the responsibilities beyond the catalog tool
A catalog finishing tool does not establish a commissioned robot cell. Put the robot, mounting, force-control mechanism, spindle drive, air regulation, extraction, enclosure, fixture and consumables into an itemized supply and commissioning schedule. Define who provides drawings, calibration, operator training, replacement consumables and safe recovery after a stop. Confirm mechanical and electrical interfaces against the exact ordered configuration rather than a promotional rendering.
The published ratings are supplier values, not results of a platform trial. There is no established material-removal rate, surface-roughness guarantee, force-control accuracy, tool life or safe unguarded operating condition on this record. Request measured trial data and the documentation required for the actual material, cell and jurisdiction. An adjustable finishing tool does not establish safe contact with people or a certified complete installation.

Questions to attach to the quotation
Which mass should I use for the robot review?
The source separates 7.2 kg for this unit boundary from 14.8 kg with force control. Begin with the signed configured assembly and add only components not already included. Review centre of gravity, wrist moments and acceleration with the robot supplier; this page does not issue a payload pass.
Do these ratings establish my finished result?
No. Define the acceptable edge, burr or surface measurement on your own parts and confirm it through a repeatable trial, including consumable wear and replacement. Supplier motor ratings cannot predict the completed process.
Does the photograph show everything included?
No. Require an itemized quotation with interface drawings, drive and control hardware, consumables, changing equipment and commissioning responsibility. The original illustration is a supplier rendering or photograph; supplied configuration and media reuse rights are not established by its presence.

Your inputs · local calculation
Build the complete mounted-mass schedule
The recorded tool assembly with force control contributes 14.8 kg. Add components once: exclude this fixed mass from your inputs. The result is robot-mounted mass, not a statement that the changer or robot permits this load.
This fixed value uses the published assembly boundary, including force control. Confirm its ordered configuration; do not add the unit mass again. Add abrasives, adapters and services only when outside that boundary. A successful exchange or a motor rating does not establish the permitted robot wrist load.
Enter your project inputs to calculate. No inputs are uploaded or saved.
Formula: recorded component mass + additional tooling + adapters/other equipment + retained workpiece. No automatic rating pass/fail; moments, load centre, acceleration and model-specific conditions need review.
