Centerless Grinding: Process, Types, Tolerances & Uses
Centerless grinding is used to finish the outside diameter of round parts such as shafts, pins, rods, rollers, bushings, and valve components. It removes a small amount of material to improve diameter accuracy, roundness, straightness, and surface finish.
Unlike conventional cylindrical grinding, the workpiece is not clamped in a chuck or held between centers. It …
Surface Grinding: Process, Tolerances, Finish & Uses
Surface grinding is a precision machining process used to produce flat surfaces, control part thickness, and improve flatness, parallelism, and surface finish. A rotating abrasive wheel removes small amounts of material while the workpiece moves beneath it on a reciprocating or rotary table.
The process is commonly used after CNC milling or heat treatment when …
Electrical Discharge Machining: Process, Types & Uses
Electrical discharge machining (EDM) is a non-contact manufacturing process that removes material from an electrically conductive workpiece through a series of controlled electrical discharges. Instead of using a cutting edge, an electrical discharge machine creates sparks across a small gap between the electrode and the workpiece. Each discharge removes a microscopic amount of material.
EDM …
Deburring: Definition, Methods, Tools, and CNC Applications
A CNC machined part can meet every dimensional tolerance and still fail during assembly. A small burr around a drilled hole may stop two surfaces from seating correctly. A loose burr inside a hydraulic manifold can break away and block a valve. On parts handled by operators, an untreated edge can also become a safety …
CNC Machined Manifolds: Types, Materials, and Cost
CNC machined manifolds combine internal passages, threaded ports, valve locations, and mounting features in a single block. They are used to distribute or control hydraulic oil, compressed air, water, coolant, gas, and vacuum within industrial equipment.
A custom manifold can replace several separate hoses, fittings, and connection points, helping the system fit into a smaller …
CNC Robotics Parts: Custom Machining, Materials, and Prototyping
Robotics is becoming a larger part of industrial automation, logistics, inspection, warehouse systems, and product development. According to the International Federation of Robotics, 542,000 industrial robots were installed worldwide in 2024, more than twice the number installed ten years earlier. Annual installations have also remained above 500,000 units for four consecutive years.
As robotics expands …
Custom CNC Machined Brackets: Types, Materials, and Cost
Custom CNC machined brackets are used when standard L brackets, U brackets, or catalog mounting hardware cannot match the required mounting position, hole pattern, thickness, clearance, load, or assembly layout. They are commonly made for motors, sensors, cameras, electronic enclosures, fixtures, machine modules, industrial equipment, and custom products.
A bracket may look simple, but it …
Small Parts CNC Machining: Materials, Processes, Tolerances, and Costs
Small parts CNC machining is used to produce compact metal or plastic components such as pins, shafts, bushings, sleeves, threaded parts, connectors, sensor housings, small brackets, and precision spacers. These parts may be physically small, but they often have demanding requirements for hole position, thread quality, burr control, surface finish, and repeatability.
Small CNC machined …
CNC Heat Sink Design: How to Design for Production
A heat sink is not designed well simply because it has more fins or uses a more expensive metal. Its real performance depends on how heat leaves the component, how quickly it spreads through the heat sink, whether air can move around the fins, how the part is mounted, and how the design will be …
