Machining Industry Conveyor Systems
Machine shops and precision manufacturing facilities face specific material handling challenges that generic conveyors don’t address. Cutting fluids spray during CNC operations. Metal chips accumulate around machines. Parts with finished surfaces require protection from scratches. Automation cells need precisely timed material delivery. Since 1984, Custom Conveyor & Equipment Corporation has been engineering conveyor solutions designed for machining environments, understanding that successful material handling in machine shops requires more than moving parts from point A to point B.
Understanding Machining Environment Requirements
Machining operations remove material through cutting, drilling, milling, turning, grinding, or other subtractive processes. These operations create conditions that affect conveyor design and performance in ways that general manufacturing applications don’t encounter.
Cutting Fluid Exposure
CNC machines use cutting fluids—coolants, lubricants, or combination formulations—to cool cutting tools, flush chips from cutting zones, and improve surface finishes. These fluids spray during operations, creating mist that settles on nearby equipment. Parts exiting machines carry coolant that drips during transport.
Conveyors in machining environments must resist coolant degradation. Materials that corrode when exposed to water-based coolants fail prematurely. Electrical components require protection from fluid ingress. Drive systems need shielding from contamination.
Custom Conveyor addresses coolant exposure through appropriate material selection and component protection. We engineer machining conveyors with coolant resistance as a fundamental requirement, not an afterthought.
Metal Chip Management
Machining produces chips—metal removed during cutting operations. These chips range from fine powder created by grinding through long stringy curls from turning operations. Chips fall onto conveyors, accumulate in corners, jam in gaps, and cause problems if not managed.
Machining conveyors require designs that prevent chip accumulation and facilitate cleaning. This includes minimizing horizontal surfaces where chips collect, providing drainage for chips mixed with coolant, and designing transfer points that don’t create chip traps. We engineer with understanding that chip management matters as much as part transport.
Surface Finish Protection
Machined parts often have finished surfaces that cannot tolerate scratching, gouging, or contamination. A precision ground surface damaged during material handling requires rework—adding cost and potentially affecting part dimensions.
Custom Conveyor designs machining conveyors with product contact surfaces that protect finished parts. This might involve specialized belt materials, roller coverings that cushion without scratching, or fixture designs that support parts at unfinished locations. We engineer these details based on the actual parts being handled and the surface finishes requiring protection.
Machining-Specific Conveyor Applications
Chip Conveyors
Chip conveyors remove metal chips from CNC machines, recovering cutting fluids while transporting chips to collection containers. These specialized conveyors operate in harsh conditions—submerged in coolant sumps or exposed to continuous chip loads and fluid flow.
Hinged steel belt chip conveyors use interlocking steel belt segments that form a continuous surface. As the belt travels around pulleys, it lifts chips from machine sumps. Coolant drains through gaps between belt segments back into the sump while chips continue to collection areas.
Scraper chip conveyors pull chips along troughs using scrapers attached to chains. These systems work well for machines producing heavy chips or where space constraints prevent hinged belt installations.
Custom Conveyor engineers chip conveyors based on machine configurations, chip characteristics, and coolant systems. We size these systems for chip volumes, design for coolant recovery rates, and build with materials that resist the corrosive nature of cutting fluids.
Part Transfer Between Machines
Machining operations often involve sequential processing—parts move from turning centers to milling machines, from rough machining to finishing operations, from cutting to inspection. Conveyors that transfer parts between machines must operate reliably in the coolant-contaminated, chip-filled environment around CNC equipment.
Transfer conveyors for machined parts typically use roller or belt configurations with features that protect finished surfaces. Rollers may have coverings that prevent marring. Belts might use materials selected for gentle part contact. Transfer points are engineered to prevent parts from sliding or tipping during transitions between conveyor sections.
We design these systems with understanding that parts arriving at downstream machines must be in acceptable condition for subsequent operations. A conveyor that damages parts during transfer adds no value regardless of how efficiently it moves material.
Automation Cell Integration
Lights-out machining and automated manufacturing cells require conveyors that precisely deliver parts to robotic handlers, hold parts in position for loading/unloading, and remove completed parts at timed intervals. These systems are integral components of automation equipment, not standalone material handling.
Automation cell conveyors incorporate position sensors that tell robots where parts are located, stops or accumulation zones that hold parts until handling systems are ready, and precise speed control that synchronizes conveyor movement with robot cycles.
Custom Conveyor engineers automation-integrated conveyors with controls that communicate with cell controllers, mechanical designs that provide repeatable part positioning, and reliability appropriate for unattended operation. These systems must function correctly when no operators are present to intervene if problems occur.
Engineering Conveyors for Machine Shop Environments
Material Selection for Coolant Resistance
Cutting fluids vary in chemistry and aggressiveness. Water-based coolants promote corrosion of ferrous materials. Straight oils may attack certain plastics or rubber components. Synthetic coolants might have pH levels that affect material compatibility.
Custom Conveyor selects conveyor materials based on the cutting fluids present in your machining environment. Stainless steel construction provides excellent coolant resistance for many applications. Certain carbon steel conveyors with appropriate coatings work well with specific coolant types. We engineer these material selections based on your actual coolant chemistry, not assumptions.
Electrical Component Protection
Machining environments expose electrical components to coolant mist and splash. Motors, controls, sensors, and wiring must resist fluid ingress that could cause failures or create electrical hazards.
We specify enclosed motors rated for wet environments, use sensors designed for coolant exposure, and protect electrical enclosures from fluid entry. Proper electrical component selection and installation prevents premature failures and maintains safe operation in machining environments.
Maintenance Access in Tight Spaces
Machine shops pack equipment tightly to maximize productive floor space. Conveyors often occupy narrow spaces between machines or fit into limited areas around CNC equipment. This spatial efficiency shouldn’t prevent necessary maintenance.
Custom Conveyor designs machining conveyors with maintenance access despite space constraints. This might include removable sections that allow access to drive components, modular construction that enables component replacement without removing entire conveyor assemblies, or strategic placement of maintenance points at accessible locations.
Conveyor Design for Machined Part Characteristics
Weight Range Considerations
Machined parts span enormous weight ranges. Precision-turned brass fittings weigh ounces. Cast iron engine blocks weigh hundreds of pounds. Large machined structures approach our capacity of 6 tons per unit. Conveyors must be engineered for the actual part weights they’ll encounter.
Our fabrication capabilities—including a 300-ton press brake for forming heavy structural members—support conveyor construction appropriate for heavy machined components. Conversely, we can design lightweight conveyors for small precision parts where heavy construction would be inappropriate over-engineering.
Geometry & Stability
Machined parts often have complex geometries that affect conveyor transport stability. Long slender shafts may tip on conveyors. Parts with small footprints and high centers of gravity are prone to falling over. Asymmetric components might roll or slide during transport.
Custom Conveyor addresses part stability through appropriate conveyor designs. This might involve side guides that prevent tipping, belt materials that resist part sliding, or custom fixtures that hold awkward geometries during transport. We engineer these features based on your actual machined parts, not generic assumptions about what machine shops produce.
Coolant Drainage During Transport
Parts leaving CNC machines carry cutting fluid that drips during conveyor transport. This coolant should drain back toward chip conveyors or collection systems rather than spreading throughout the facility or contaminating downstream operations.
We design machining conveyors with appropriate drainage—sloped surfaces that direct coolant flow, perforated belts that allow fluid drainage while supporting parts, or collection pans beneath conveyors that capture dripping coolant. Proper drainage engineering keeps machining operations cleaner and recovers valuable cutting fluids.
Precision Fabrication for Machining Applications
Machine shops appreciate precision—it’s fundamental to their business. Custom Conveyor brings this same precision focus to conveyor fabrication for machining environments.
Laser Cutting Accuracy
Our 3kW fiber laser cutting system processes steel sheets up to 6 feet by 12 feet with the tight tolerances machining applications demand. Conveyor components are cut to precise dimensions, ensuring proper fit during assembly and alignment during installation.
This cutting accuracy matters for machining conveyors where component precision affects performance. Transfer mechanisms need accurate positioning. Mounting holes must align correctly. Parts that fit precisely during fabrication create conveyors that operate correctly during use.
Structural Forming Capability
The 300-ton press brake in our Cedar Rapids facility forms conveyor structural members with consistent angles and dimensions. This forming capacity supports both light conveyors for small parts and heavy-duty systems for large machined components.
Multi-Material Welding
Different machining environments require different conveyor materials. Standard machine shops often use carbon steel conveyors with appropriate coolant-resistant coatings. Precision grinding operations might specify stainless steel construction for cleanliness and corrosion resistance. Our welding capabilities span carbon steel, stainless steel, and aluminum, allowing material selection appropriate for each machining application.
