Cutters
Sample Pack
A Sample Pack gives the team cut pieces from the actual material before tooling is signed off. It is used to compare edge finish, burr, heat mark and shape retention under the machine settings planned for production. The pack makes it easier to judge the cut by hand, by eye, and against the drawing.
What goes into the pack
Sample Pack is for teams that need physical examples before locking in tooling or a cutting method. It helps compare cut quality, edge condition and material behaviour using samples tied to the actual job.
Each Sample Pack is built around the stock, thickness and cut detail under review. Sheets, rolls or boards can behave very differently once feed rate, blade condition or hold-down pressure are changed. Johannesburg dust, Durban humidity and Cape Town salt air can all influence how samples are stored and checked after cutting.
Include one photo of the current setup if the job is replacing an existing process. The pack should carry a short note showing material grade, cutter type and any settings used for the sample run. That record is useful when operators compare a good edge against later production pieces.
Checks done from the samples
Use the pieces in the pack to inspect edge quality, fit and material response before ordering full tooling. Some teams mark each sample with machine, date and test condition so the result can be traced back properly. A small set of labelled examples is often more useful than a long email thread about cut appearance.
Match the Sample Pack to the relevant notes under Cutters, Applications and Edgework before expanding the job scope. Check the sample labels, tooling reference and delivery note again before anything leaves for review.
- Physical pieces cut from job material
- Edge condition checked against actual requirement
Conditions that affect sample results
Production environments differ, and the samples need to reflect that reality. OR Tambo export handling, Sunnyrock dispatch timing, older Crown Mines equipment layouts and smaller showroom workspaces can all shape how test pieces are prepared and reviewed. Separate trial cuts for urgent orders from samples meant to settle the standard production method.
Coastal air can leave fine residue on stored pieces, while inland dust may change how cleanly guides and sensors perform during a run. Load-shedding can interrupt first-article checks and should be noted if the machine was restarted between cuts. A viewing slot should be used to compare finish, tolerance and tooling marks, not to guess what changed.

Details to send with samples
State the material, thickness, quantity needed and the fault that must be tested or avoided. Add photos of failed edges, tool wear or the present nesting layout where relevant. Good sample notes save time when different cutters or pressures are being compared.
Keep this note with the project record while the machine model, blade geometry, and test pieces are still easy to verify. It gives purchasing and production one reference for the agreed sample, the observed edge finish, and any care points raised during checking.
