Multi-Spindle Machining

Multi-spindle machining uses several spindles to simultaneously perform multiple tooling operations on a single workpiece. These machines are suitable for high-volume, low-complexity primary operations because they provide high levels of accuracy while lowering cycling times.

DaCruz Manufacturing works with OEMs in various industries that require exacting specifications. As the Northeast’s leading precision manufacturing partner, we use cutting-edge technologies to address our customers’ challenges at competitive rates.

Multi-Spindle CNC Screw Machining

In machining, a spindle is the rotating unit of a lathe, and its standard components include the shaft, bearings, and more. The multi-spindle screw machine involves mounting multiple spindles with different tool heads to a rotating drum. As the drum rotates, several operations are carried out to complete the component in a single cycle.

CNC multi-spindle screw machines have shorter cycling intervals and higher precision because simultaneous tool procedures are applied to the turning bar stock.

Advantages of Multi-Spindle Machining

Some of the benefits of multi-spindle machining are as follows:

Simultaneous Delivery of Multiple Functions

Multi-spindle machining allows for a wide range of functions to be performed at the same time. These capabilities include turning, drilling, slotting, knurling, cross-drilling, threading, and broaching.

Improved Energy Efficiency

Using fewer machines to accomplish tasks that normally require multiple machines results in lower energy costs. Because multi-spindle machining performs numerous functions simultaneously, it consumes less energy than several single-spindle machines working to accomplish the same results.

Reduced Production Times and Costs

Multi-spindle machining produces a short cycle time by allowing up to eight simultaneous operations. This allows the process to be completed quickly and efficiently, lowering machining costs. Furthermore, multi-spindle CNC machines achieve speeds up to five times faster than single-spindle machines.

Increased Capacity and Productivity

This process provides increased capacity and shorter cycling times for high-volume production since it requires lower personnel-to-machine manning ratios.

Consistent Accuracy of Results

Multi-spindle machines have higher accuracy and efficiency levels. They can hold tolerances down to 0.05 mm. in diameter, ensuring that high precision is maintained even when producing small components. This also provides easy maintenance of control practices because the machines deliver consistently precise products.

Multi-Spindle Machining Applications

Multi-spindle machines can produce a wide range of products in large quantities. The following are some of the most common applications for this machining process:

Bushings

A bushing is a vibration isolator that acts as an interface between two parts, dampening the energy that passes through it. It is frequently shaped as an annular cylinder of flexible material contained within a metallic casing or outer tube. It may also include an internal crush tube to prevent the bushing from being clobbered by the fixings that secure it to a threaded spigot.

Bushings are commonly used in vehicle suspension systems to separate the faces of two metal objects while allowing for some movement.

Spacers

A spacer is a tube-like, unthreaded structure that separates two parts in an assembly. It can be made of metal, plastic, glass, or other materials and ranges in size from microns to centimeters. Furthermore, it allows for increased airflow and prevents potential electrical shortages by stopping components from touching one another.

Spacers are used in applications that require tight tolerances, such as PCB mounting.

Bearings

A bearing is a machine component that restricts relative movement to only the desired motion while reducing friction between moving parts. It supports the rotating shafts of the machines’ wheels, gears, turbines, and rotors, allowing them to rotate more smoothly.

Applications that utilize bearings include automobiles, airplanes, and electric generators. They are also used in household appliances, such as refrigerators and vacuum cleaners.

Fasteners

A fastener is a piece of hardware that mechanically connects two or more objects. It is typically used to create non-permanent joints which can be removed or disassembled without causing damage to the joining components. In addition, fasteners come in infinite shapes, sizes, lengths, and varieties, ranging from the common nail to massive bolts used to secure heavy-duty manufacturing equipment.

Fittings

Fittings are the connecting components that join machine parts to tubes and other pipes. They must be securely attached to one end and bound to a larger segment. The other end is then used to connect hoses, nozzles, or pipes that would otherwise be unable to link to the core element they are leading.

Inserts

Inserts are detachable cutting tips that are not brazed or soldered to the tool body. They are typically indexable, which means they can be exchanged and frequently rotated or flipped without affecting the overall structure of the tool.

Panel Screws

Used to attach boards or panels in a semi-rigid manner, panel screws allow the attached surface to be removed for repair or inspection of the basic equipment. They are frequently available as one-piece assemblies, allowing for fast spring-loaded discharge and retention with various mounting options and drive techniques.
