CNC Shop Expansion Checklist: Machines, Space, Power & Staffing

Being able to expand your business is a happy moment for every business owner out there, and the same applies to CNC machining shop owners, too. But sometimes people make wrong decisions during a business expansion that kill all the happiness, as they don’t consider everything properly, and then regret their decision afterwards. So, one needs to make proper calculations before doing the expansion, so that one can make a decision that’s profitable for them. Now, if you are a manufacturing shop owner who is planning to grow, here is the CNC shop expansion checklist that you need to follow.

Top Things to Check When Doing CNC Shop Expansion Planning:

Here are some of the major factors that you need to keep in your CNC shop expansion checklist when planning to expand:

1. Identify the Purpose of Expansion:

The first thing one needs to decide before going ahead with the CNC machine shop growth is to identify the purpose of the expansion of the shop. Many shops expand because they want to increase their production capacity, while others expand to improve their capability with multi axis machining or turn-mill operations.

Here are some questions that you need to ask yourself:

Are you going to increase your production volume?
Are you planning to machine larger parts?
Are you trying to add new machining capabilities?

2. Evaluate your Current Machine Utilization:

The next step of expansion planning is to properly review how efficiently your current machine is getting utilized. Some CNC machine shops just go ahead to add more machining capabilities without properly analyzing the current utilization level. In many cases, shops don’t know a new CNC machine; they just need to utilize the old machine properly.

Here are some of the things that one needs to evaluate:

Setup times
Idle machine hours
Job scheduling efficiency
Average spindle utilization

If the machines are already operating at their full capacity, then expansion through adding machines can be justified.

3. Choosing the Right CNC Machine:

Once your analysis has led you to the conclusion that you need more machines for expansion, then it is time to try to find the right machine for your manufacturing shop. Different machines are available in the market to serve different kinds of customer requirements, for example:

CNC machining centers for milling operations
CNC lathes or turning centers for turning operations
Mill-Turn machines for complex part manufacturing operations

When evaluating a CNC machine for your manufacturing shop, one needs to consider different factors like:

Tool capacity
Control system compatibility
Spindle speed and torque
Automation option
Axis travel

4. Considering Used CNC Machines:

When planning for growth, one needs to decide whether they want to go ahead with a completely new CNC machine or a used model. If you are tight with budget, then buying a used machine might be a better choice for you. Used CNC machines help shop owners to expand their capability without committing a big amount in upfront cost. When evaluating used CNC machines, one needs to review:

Overall machine condition
Machine’s specifications
Control system compatibility
Maintenance history (if available)

So if you want a used CNC machinery for your CNC facility expansion, then you can check MachineStation’s collection.

5. Plan the Shop Floor Layout:

The next step of CNC shop expansion planning is the shop floor layout. Adding machines without proper shop floor management planning can create workflow problems inside the machining shop. Here are some important layout considerations that you need to make:

Material handling paths
Space required for machine operation
Clearance for tool changes and maintenance
Chip disposal areas
Forklift or crane access

Efficient shop layout planning helps in improving the overall productivity of the manufacturing facility.

6. Evaluate Power Supply:

Another important point that should be included in your CNC shop expansion checklist is the CNC power requirements. Before shops install any additional CNC machines, they need to evaluate their existing electrical infrastructure. Here are some of the major energy factors that one needs to consider:

Available power capacity in the shop
Number of electrical panels
Backup power availability
Voltage requirements of the new machine
Load distribution across equipment

In different shop scenarios, adding a CNC machine will require electrical upgrades.

7. Assess Staffing Requirements:

Last but not least, one of the important factors to consider for CNC facility expansion is CNC staffing planning. More machines usually need more skilled operators, programmers, and maintenance personnel. Here are the key people of CNC staffing planning you need to consider:

CNC machine operators
CNC programmers
Quality inspectors
Maintenance technicians
Setup technicians

Conclusion:

CNC shops’ growth planning is as important as inspecting or buying a CNC machine. If you end up buying a CNC machine without having a proper environment in your shop for that machine, then that will become a huge problem for you. So, make sure you have a proper checklist for your CNC shop expansion and then take the necessary steps to make your facility ready for expansion.

FAQs:

1. When should a CNC machine shop consider expanding?

A CNC shop may consider expansion when existing machines are running close to full capacity, lead times are increasing, or the shop begins receiving new types of machining work.

2. How do used CNC machines help during shop expansion?

Used CNC machines allow shops to add production capacity without the cost associated with new equipment. Many manufacturers use used machines to increase machine count while managing capital expenditure.

3. Does adding more machines always increase production efficiency?

Adding machines can increase production capacity, but efficiency also depends on workflow, scheduling, and operator availability.
