Consumables for cryogenic rubber trimming machine – supply of liquid nitrogen
The frozen rubber deflashing machine, as an essential auxiliary manufacturing machinery in the production process of rubber enterprises, has been indispensable.
However, since its entry into the China mainland market around the year 2000, local rubber enterprises have little knowledge of the working principles and processes of the cryogenic deflashing machines.
Therefore, this article will provide a detailed introduction to the storage and supply methods of the cryogen, liquid nitrogen, for the cryogenic deflashing machines.
In the past, liquid nitrogen was typically stored in separate liquid nitrogen tanks. Therefore, when purchasing a cryogenic deflashing machine, it was necessary to buy a matching liquid nitrogen tank to ensure the proper operation of the machine.
The installation of the liquid nitrogen tank required approval from the relevant authorities, which was a cumbersome process, and the tanks themselves were expensive. This has led many factories that urgently need to use cryogenic deflashing machiness to improve work efficiency to hesitate, as it also involves a certain upfront cost investment.
Nanjing PEGE has introduced a liquid nitrogen manifold supply station to substitute for liquid nitrogen tanks.
This cryogenic deflashing system centralizes the gas supply of individual gas points, enabling multiple low-temperature Dewar flasks to be combined for centralized gas supply. It solves the cumbersome process of handling liquid nitrogen tanks, allowing customers to operate the cryogenic deflashing machines immediately after purchase. Above are good options for the container of the Liquid Nitrogen.
The main body of the cryogenic deflashing system simultaneously connects three bottles of liquid nitrogen Dewar flasks, and it also includes a port that can be expanded to accommodate four bottles.
The cryogenic deflashing system pressure is adjustable and equipped with a safety valve. It’s easy to assemble and can be mounted on the wall using a triangular bracket or placed on the ground using the bracket.
Nanjing PEGE always provide strong technical support for customer to better use the cryogenic deflashing system.
On the year of 2022, one customer from Colombia sent some samples for testing. The rubber parts to be deflashed are rubber O rings.
You can see from following photo:
There are many flashes which are difficult for manual deflashing.
After Cryogenic deflashing, we can get good results without flashes.
Even though the deflashing result was acceptable, customer was hesitating to make decision to purchase the cryogenic deburring machine due to the budget problem.
They paused the purchase this nitrogen shot blasting deflashing machine.
On the year of 2025, last year, customer restarted the project and we talked about the model and the offer and finally we made a deal to sell the cryogenic deflashing equipment Model PG-60T to customer.
It is a wonderful machine for automatic rubber deflashing process, it is well designed and well manufacturered.

Can You Improve the Efficiency of CNC Machines?
Yes, CNC machining output can be significantly enhanced with a focused approach. With all those interacting components; tooling, fixtures, code, parameters, equipment etc, there are numerous opportunities for optimization and performance enhancement. Before initiating any changes (toolpath optimization, tool refreshment, automation, etc.) you need to identify your present limitations and bottlenecks.
Manufacturers running older legacy CNC machines can still maximize efficiencies by upwards of 20 percent through improved workflows, tools, probes, and out-of-the-box fixturing solutions. And today's more sophisticated machines and software provide further opportunity for cycle time reduction and tool longevity. The strategies outlined below can lead manufacturers to best in class benchmarks.
Importance of Efficiency
In today's highly competitive manufacturing environment, companies must continually improve productivity and cost structures to thrive. For shops using CNC machining as a core competency, maximizing the efficiency of those processes is mandatory.
Failing to optimize machine performance can sink profit margins and lose business to rivals with better capabilities and economics.
Some key reasons that excelling at CNC efficiency matters include:
● Competitiveness: Efficient CNC usage is imperative for manufacturers to offer competitive pricing and lead times to customers. Meeting demands rapidly and cost-effectively depends directly on optimized machining.
● Profit Margins: Boosting efficiency directly improves profitability by cutting cycle times and material waste. Machining identical components faster and consuming less raw material saves real dollars.
● Shop Capacity: Streamlining the CNC process enables shops to take on more work and grow business. A 20% cycle time reduction expands available machine capacity by the same amount.
● Responsiveness: Having CNC efficiency gains translates into the responsiveness and agility to take on rush jobs or rapidly adjust to customer changes. Quick changeover and throughput make shops more adaptable.
● Quality: Refining machining processes through speed optimization, precision fixturing, and tool management inherently improves end part quality by reducing errors and variability.
Top 7 Tips to Improve the Efficiency of CNC Machine
1. Optimizing Toolpaths for Efficiency
One of the most impactful steps toward faster, leaner CNC machining is optimizing the toolpaths generated in CAM software. These toolpaths govern everything from machining sequence, tool selection, and travel paths to cutting strategies, heights, and spindle speeds.
Modern CAM systems provide extensive options to dial in high-efficiency toolpaths tailored to the part, tools, and machine in use.
Utilizing an advanced CAM system allows shops to program optimized toolpaths that significantly cut machining time while extending tool life and improving surface finish. Let's look at key efficiency-enhancing capabilities in CAM software:
● Determines optimal machining sequence considering part geometry, features, tool requirements, and machine kinematics. The sequence selected directly affects total cycle time.
● Defines toolpaths with minimized non-cutting travel that reduces cycle times by eliminating unnecessary tool movements. Close attention to travel keeps the tool constantly engaged in material removal.
● Manages material removal volumes by optimizing step-downs, stepovers, and other cutting parameters that influence tool load. This preserves tool life while avoiding excessive light cuts that waste time.
Efficient Toolpath Generation:
Some key strategies that CAM software employs to generate highly efficient toolpaths include:
● High-Speed Machining: CAM programming for HSM techniques like trochoidal milling cuts cycle times through faster feed rates and reduced tool loads. This is applied across suitable feature types.
● Toolpath Smoothing: Smooth spline interpolated toolpaths maintain precision while allowing faster feeds than point-to-point moves. This reduces jagged movements.
● Tool Axis Control: For 3+ axis machines, controlling tool orientation expands access to reduce tool changes and setups. Indexing the axis configurations expands efficiency.
● Plunge Roughing: Specialized roughing patterns focused on plunging cuts maximize material removal with lighter radial loads to preserve tool life.
● Rest Machining: Leaving a thin layer of stock material to remove in the final pass enables using the most efficient tool only where needed.
● Gouge Protection: Automatic gouge checking ensures safe toolpaths to avoid machine crashes that cause extensive downtime and recovery.
2. Effective Workflow Planning
While advanced CAM software handles much of the toolpath details, shops should still analyze overall workflow for process improvements. Often, greater efficiency gains come from updating workflows and material flows compared to tweaking machine parameters.
Steps to evaluate and streamline the machining workflow include:
● Map current workflow from raw stock to finished parts to visualize bottlenecks like queue times, transport batches, inspection stops, or other delays.
● Identify constraints limiting output like fixture changeover, tool availability, or probing. Look for what slows production flow.
● Overlap processes like machining one batch while probing the previous batch to make operations parallel rather than sequential.
● Right-size batches through work-in-progress analysis to find optimal transfer batch size between operations. Too large or small is inefficient.
● Standardize setups and workflow so all operators consistently follow the established best practice process. This is enabled through the setup of photos, videos, and checklists.
3. Proper Machine Selection and Setup
A key prerequisite for high-efficiency machining is matching part production to the appropriate CNC machine model and configuring the setup precisely. Having advanced software driving a simple 3-axis mill or asking a basic machine to hit tolerances beyond capability will inevitably result in disappointment.
Let's examine machine selection and setup considerations:
● Horsepower & Torque: Match machine motor capabilities to anticipated material removal rates and tooling requirements with overhead to spare. Underpowered machining leads to extensive wear and long cycle times from reduced speeds and feeds.
● Precision: Part tolerance and finish needs should guide builders to machines delivering the required accuracy through features like ballscrew quality, servo performance, material rigidity, and thermal stability.
● Tool Capacity: Necessary tool types, sizes, and counts dictate physical tool magazine capacity and carousel designs. Too little capacity risks time-consuming tool changeovers and recovery.
● Automation: For optimal efficiency, machine tools should be specified to match adjacent automation like robots, gantry loaders, and conveyors based on parts weights, volumes, transfer speeds, etc.
Precision Workpiece Setup
To leverage machine tool investments fully, shops must configure workholding solutions that locate parts precisely with quick changeover ability. This enables accessing the full working envelope and avoids setup-induced errors that reduce efficiency.
Some recommended setup practices include:
● Indicating parts on precise locating points using reliable techniques like edge finders, wireless probes, and laser systems.
● Modular fixturing with quick change capability to swap parts in and out rapidly.
● On-machine inspection via wireless probes to validate setup accuracy and identify any positional errors early.
● Secure clamping through sufficient clamp pressure and locators to avoid workpiece movement under cutting forces.
4. Advanced Tooling Strategies
Tooling is the critical bridge between machine tools and raw materials that governs factors like removal rates, operating speeds, power demands, and finish quality. Optimizing tooling selection, usage, and management is integral to smart CNC operation.
Utilizing the latest tool geometries and coatings while managing tool life actively through carousel systems helps improve program performance.
Significant cutting efficiency gains come from employing the newest generation of advanced cutting tools that outperform previous designs. Characteristics of these upgraded tools include:
● Tool Geometries: New shapes like variable helix/variable pitch end mills or Silent tools enhance finishes, accuracy, speeds, feeds, and life.
● Coatings: Refined coatings like Amorphous Diamonds further push heat and wear resistance to cut faster.
● Specialty Tools: Tools tailored for efficiency like harpoon drills, chatter-preventing geometries, or multichannel chip breakers improve specific operations.
These upgraded tools boost output through better speeds, feeds, and tool life. However, their higher performance capabilities can only be realized by optimizing cutting parameters.
Tool Management Systems
Besides using top-tier tooling, having an effective tool management system is mandatory for serious efficiency. Key functions of these advanced systems include:
● Tool Presetting: Measuring tools offline enables zeroing offsets to eliminate test cuts and manual intervention. This saves setup time and materials.
● Tool Life Tracking: By tracking tool usage and wear, operators know when tools need replacing before breakage or dimension errors occur.
● Tool Changers: Quick automatic tool changers minimize the downtime associated with swapping tools to keep machines cutting more of the time.
Through capabilities like presetting, tracking usage, and enabling fast changeovers, tool management solutions are indispensable for highly efficient CNC operation.
5. Optimizing Cutting Parameters
The cutting parameters specified in machining programs exert tremendous influence on cycle times, tool wear rates, machine loads, and other key efficiency factors.
While CAM systems suggest initial parameters, real-world variables mean optimal settings must be found through experimentation and monitoring.
The core parameters impacting efficiency include:
● Spindle Speeds: Rotational tool speeds dictate suitable feed rates. Optimal speeds balance tool life versus cycle time considerations.
● Feed Rates: The travel rate while engaged in the cut impacts forces, tool deflection, and heat generation. Finding the peak safe rate minimizes time.
● Depths of Cut: Determining maximum depths before tool overload lets operators program roughing cycles more aggressively to remove material rapidly.
Continually testing and adjusting these values is necessary to account for factors like actual tool sharpness, material variations, environmental changes, etc. Conservative CAM estimates must be pushed to reap efficiency gains.
6. Integrating Automation and Technology
Seeking to squeeze cycle time savings purely from CNC machines eventually hits diminishing returns. More impactful efficiency improvements come from integrating complementary automation and technology around the base machines.
This advanced equipment works to keep parts flowing with less human intervention, while software reduces programming bottlenecks.
Instead of relying on manual programming, automated CAM processes drive efficiency through:
● CAM Templates: Standardized program templates with stored best practices reduce programming time and enforce consistency.
● Parametric Programming: Rules-based programming adapts automatically to design changes without coding from scratch.
● Post Processor Tuning: Refining machine code output from CAM through optimal post configs avoids manual optimization of G-code. This ensures maximally efficient code generation tuned for the exact shop environment.
● Simulation: Automatic CAM simulation detects collisions, inefficiencies, and errors in toolpaths before attempting test cuts to save materials and unproductive machine time.
Together these automated CAM capabilities slash programming overhead while producing highly optimized machine code. This frees programmers to handle higher-value tasks.
7. Regular Maintenance and Training
While advanced tools, automation, and refined processes aim to minimize interruptions, breakdowns, and suboptimal performance are inevitable without diligent maintenance and training. Together these complementary initiatives maximize uptime and ensure operators follow best practices.
Even with resilient machine construction, continual operation subjects components to substantial wear. Without vigilant preventative maintenance, breakdowns cause extended outages. Critical activities include:
● Fluid Changes: Regularly replacing hydraulic oil, coolant, and lubricants based on usage intervals keeps damaging particles from circulating.
● Component Lubrication: Greasing ballscrews, way covers, and gearboxes avoids binding and sticking.
● Way Scraping: Precision hand scraping of mating surfaces maintains position accuracy as machines age.
Conclusion
This guide covers techniques like optimizing toolpaths, streamlining workflow, integrating automation, and more for dramatically increasing CNC machining efficiency.
While upgrading older equipment can deliver gains, modern CAM software and machinery combined with a focus on total process efficiency makes possible reductions in machining times of 50% or more versus legacy systems.
The common theme across these tips is analyzing each component and interaction for bottlenecks using data. Addressing limiting factors with tailored solutions leads to compounding gains.
Matching advanced tools and programming with smart workflows, maintenance, and operator skills builds a high-efficiency foundation for competitive manufacturing success.
