Aluminum cutting and drilling should be planned from the finished part’s references and required features. Compare cutting blanks before drilling, machining features on stock before separation, and a combined processing line. The right proposal depends on the actual drawings, handling provisions, feature access and evidence for the complete part.
A saw quotation and a drilling quotation can each look complete while their handover remains undefined. Use these four decisions to connect the operations before comparing equipment.
Define the complete part first
- Keep finished ends and hole references on the current drawing.
- Ask which operations and transfers the proposed configuration covers.
- Review the final part, not only one stage’s output.

Decision 1: define the finished drawing for aluminum cutting and drilling
Send one current part drawing that identifies the section, material condition, finished length, end angles and required holes. Include hole type, size, position and the referenced features where the drawing requires them. State whether the work includes drilling, tapping, countersinking or another operation.
Identify which end or face provides the hole-location reference. A raw stock end, a saw-cut end and a later machined end can represent different stages. Keep the approved reference with the proposed sequence.
If an end is trimmed or machined after a hole is made, the relationship between that hole and the final end needs review. The existence of a correct-looking hole on the stock does not establish its final drawing position.
For mitered parts, state the intended length and hole references without assuming every dimension starts at the long point. Use the miter-length reference guide when clarifying the finished geometry.
Keep handed parts separate. Two members can share a nominal length and hole count while needing mirrored feature positions. Use individual part identities and orientation references rather than combining them into one unqualified quantity.
Decision 2: compare the proposed processing routes
Route A: cut blanks, then machine the required features
Ask how the cut blank is identified and located at the next station. Clarify the end reference, orientation and any required allowance. The drilling process needs provisions for the actual blank and required feature access.
Define the condition in which the blank is transferred, including any agreed edge, chip, fluid or surface requirements. Keep waiting, handling and locating steps inside the quotation scope where they are required.
Route B: machine features on stock, then separate the parts
Ask how the feature pattern relates to each finished part’s ends and identity. Confirm how separation, trims and any later end machining are represented in the proposed process. Do not infer that a long-stock program automatically preserves every finished-part reference.
The supplier needs to review the complete sequence for the actual section. Stock support, feature access, locating and the resulting part condition belong to that review; this guide does not specify a drilling or cutting setup.
Route C: use a combined processing configuration
Integrated equipment can include several operations, but the module names alone do not establish that every feature in your drawing is covered. Ask which faces and ends can be processed, which functions are included and which provisions remain optional or outside scope.
The elumatec SBZ 628 S description provides an example of a profile-processing system with routing or drilling functions and length cutting. Emmegi’s Quadra L3 page describes milling, cutting and head/end drilling modules, together with workpiece handling. These are examples of other manufacturers’ documented configurations. They do not establish equivalent JiurunCut features, universal feasibility or a preferred route for your part.
| Proposed route | Key review question |
|---|---|
| Cut, then machine | How is the blank located and identified at the next station? |
| Machine stock, then cut | How do features relate to the final end references? |
| Combined processing | Which features, modules and transfers are actually included? |
Compare routes using the same finished drawing and required result. Avoid comparing one quote for a cut blank with another for a completed drilled part without making that scope difference visible.
Decision 3: define the handover between stages
Name the part, batch and revision that travel with the work. State which operations are complete, which remain and what condition the receiving stage expects. Physical material beside a machine is not enough to communicate that status.
Clarify who supplies the transfer, storage, marking or data provisions required by the chosen route. If information must pass between systems, ask how that interface works and request evidence for the proposed configuration. A shared CNC label does not prove compatible file or program transfer.
Keep a finished-part identifier separate from a raw stock code. Record how mirrored members, mixed lengths and different hole patterns remain distinguishable through handling. Use the batch-traceability guide to define the required connection.
Discuss the relevant drawing and cut-list revision controls. A change to finished length or hole location should trigger review of every affected stage, including the transfer information.
Decision 4: review evidence for the complete part
Agree which finished-part requirements the sample review will check. Keep cut length and end condition alongside hole size, position, type and any required assembly relationship. Identify the actual section, material condition, orientation and configuration used.
For a fictional order of 40 parts with two specified holes each, the plan contains 80 holes. That count does not establish 40 accepted parts. If one part has an unacceptable hole and the other 39 meet every required check, the accepted finished-part count is 39.
This is a counting example, not a production result or a hole-per-minute estimate. A counter for cutting or drilling events measures its configured event; it does not automatically represent accepted final parts.
Request the observed results and note requirements that remain unchecked. A video of one operation can introduce equipment, while the sample-review checklist helps define what evidence the complete task needs.
Do not apply a cutting-only accuracy statement to drilled-hole positions or a combined assembly result. Each claim needs its own defined feature, method, scope and supporting evidence.
Watch the cutting operation in context
This video from JiurunCut’s channel presents the JR-455Q cutting demonstration. Use it to introduce the cutting stage when discussing a separate downstream operation. It does not document a drilling station, measured hole position or a completed cutting-and-drilling trial.

Build a clear proposal request
Provide the section and finished drawings, material condition, stock lengths, quantities and relevant feature references. Describe the route you want reviewed, or ask the supplier to explain the proposed route for those parts.
List the boundary between operations: the condition and identity of transferred work, required fixtures or locating provisions, handling and data responsibilities, and final inspection scope. Retain supplier exceptions rather than treating an unanswered point as included.
Compare complete proposals using the same task. Keep any output, cycle, tolerance or capability claim tied to the actual configuration and evidence. A longer equipment list does not alone establish the better process for your drawing.
Questions about aluminum cutting and drilling
Should I always cut before drilling?
No universal route follows from the operation names. Review the finished references, actual section, locating and access requirements, configuration and complete-part evidence.
Does a CNC saw also drill?
Not automatically. Confirm the actual functions and included modules in the model-specific proposal. CNC control alone does not establish a drilling function.
Can a cutting video prove the whole process?
No. Use it for the operation visibly presented. Hole-location capability and final acceptance need the corresponding evidence.
Discuss the complete part with JiurunCut
Send the current finished-part drawings and identify the cutting and downstream features that need review. State which equipment and transfer responsibilities you want included in the proposal.
