Optional features include automatic lubrication system, flowmeter, carousel and tub dividers, tachometer, air-operated discharge door, gate cleaning feature, electrical controls, sound hood and more.
Spindle Machines
The ALMCO Spindle Machine is a high-speed, precision deburring machine for finishing single parts one at a time or several smaller parts on one fixture. The machine holds the part(s) on a rotating spindle that is lowered into a rapidly moving tub of abrasive media. The most common abrasive media used is a fine, granular aluminum oxide. Other choices for media are pre-shaped plastic, ceramic, steel, corn cob and walnut shell. The abrasive media swiftly flows over the part(s) as it rotates in the tub removing sharp edges and improving surface finishes. The media moves at up to 1000 surface feet per minute past the part. This is a very aggressive process and often cycle times are less than one minute per part per spindle. The “2SF” machine models have two spindles and may produce two parts per minute. These machines are available in a basic unit that must be loaded by hand or the “RA” series that is typically fully automated with a robotic loading system. Various applications include shafts, transmission components, gears, aerospace parts, medical parts, automotive parts, firearm components, bearing races, etc. These machines are custom configured to meet individual customer’s requirements. The process is very repeatable, and these machines are often used for high-precision components.
Standard features include repeatable load and process positions that allow for easy integration with robotic production lines, easy to use operator touch screen controls (standard on RA models only), spring-hold air-release tooling, variable speed tub, adjustable part positioning and eight different models to meet your specific needs.
Optional features include spindle orientation, spindle flush stations, safety enclosure, hydraulic-actuated tooling to hold parts and more.
Sutton Machines
The ALMCO Sutton Machines are aggressive, spindle-finishing units that are primarily designed to finish turbine disks, blades, blisks and impellers, with the capability of finishing many other types of parts. All Sutton machines are heavy-duty units that are designed for high production environments. Series available include:
CF SERIES
This machine is typically used for finishing turbine blades in a rotating tub of abrasive media. The machines have two spindles and each spindle holds one or two parts per cycle. These are similar to the ALMCO spindle machine, but even more aggressive.
CFT SERIES
These machines turn a large diameter part that is attached to the spindle at a high speed while the part is submerged in a large, vibrating tub of abrasive media and processing liquid. The media and processing liquid flow through the part’s features to deburr the edges and blend surfaces. Disks, blisks and impellers are typical parts processed in these machines
CFCA SERIES
These machines hold a large diameter part on an oscillating spindle that is lowered into a vibrating tub of abrasive media and processing liquid. The media and processing liquid flow through the part’s features to deburr the edges and blend surfaces. The oscillation allows the abrasive slurry to access valleys that would be difficult to finish with the CFT Series machine. Disks, blisks and impellers are typical parts processed in these machines.
Standard Features
Include PLC touch screen control, automatic lubrication systems, interlocking safety doors and flowmeter.
Optional features include compound dispensing sytems, hourmeter, operator work platform, tooling and more.
Barrel Machines
The ALMCO Barrel Machine is a durable tumbling unit designed to finish batches of parts or larger individual parts. The machine processes parts by rotating them in a multi-sided, urethane-lined barrel that is also filled with processing media and liquid compound. The tumbling action inside the barrel deburrs the parts as the top section of media continuously slides down the incline created from the barrel rotation.
Standard features include ½" thick urethane-lined barrel for long life, pressure-relief system to relieve barrel pressure prior to door removal, variable speed barrel for process flexibility and either one or two compartments.
Optional features include tachometer, forward-reverse keylock selector switch, rotary union assemblies and more.
Centrifugal Barrel Finishing
Centrifugal barrel finishing (CBF) systems from Mass Finishing offer high-speed surface improvement. They feature four hexagon shaped barrels that rotate on a drum in a planetary motion at a one-to-one ratio. MFI has eight standard size units to meet various part size and volume demands from 12 to 330 liter capacity. CBF systems are often referred to as high-energy solutions because they apply a force of 10–12g on media and parts. The system can use any type of media and can both deburr and polish parts. Surface finishes of less than 1 Ra can be achieved. Barrels can also be divided to separate individual parts to eliminate impingement.
Standard features include variable speed drive for process flexibility, 4-8 removable barrels on 40 L and smaller unit, fixed barrels with barrel rotation motor on HZ-60 and larger unit, two button turret jog requirement, safety interlocked doors during processing, semi-automated cover removal system and ¼" thick hot-poured, removable barrel liners.
Optional features include touchscreen HMI PLC Controls for increased automation, built-in media and parts separation, wastewater handling system, barrel dividers to eliminate part-on-part contact, processing station and sludge tank, safety light curtains and more.
Centrifugal Disc Finishing
Centrifugal Disc Finishers are high-speed machines that may be utilized for both deburring and polishing applications. Their open top loading and unloading features make them easy to automate into an inline production. 6 to 8 G forces are produced by the disc spinning at the bottom of the bowl and moving against the stationary side walls. A powerful vortex is created at the bottom of the finishing chamber helping to achieve fast finishing results.
Standard features include variable speed drive, hot-poured polyurethane liners, twist gap adjustment method, flow through drainage system, semi-automated unloading and process cycle timer.
Optional features include touchscreen HMI PLC controls, built-in media and parts separation, wastewater handling system, fully automated loading and unloading, automatic liquid compound dosing and more.
