Each Abtex deburring and surface treatment system,consisting of a deburring machine and a customized set of deburring brushes, offers increased productivity, consistent quality and improved operator safety.

Productivity -- As expected, deburring equipment cycle times are improved dramatically over off-hand deburring.

Quality -- Depth of brush penetration is accurately set and maintained throughout the deburring cycle, minimizing the effect on the lateral surfaces.

Safety -- The multidirectional wiping action of the disc brushing tool eliminates the need for rotating the part. The part is securely clamped during the deburring cycle.

1. Single End Deburring:

Top

Our single head end deburring machines are available in either a manual or a semiautomatic configuration. Within the system, a disc brushing tool is rotated on the vertical plane, and the extrusion end is presented, in a controlled manner, to the face of the brush by the deburring equipment.

A. Manual System: Setup and operation of this deburring machine requires minimal training. Necessary adjustments for extrusion dimensions and desired brush penetration are easily made. The operator then secures the extrusion to the table with the clamping "arm" and begins to move the table through its range of motion. The extrusion end is first passed through the upper half the deburring brush. As the table reaches its travel limit, the motor/brush assembly indexes upward, and the extrusion returns through the lower half of the brush, completing the deburring cycle. Cycle time is variable.

Model# 1000-SA-14

Single end deburring machines accommodate parts measuring from 4" to 46" in length.
Table extension is available for parts over 46" in length.
Fixturing can be designed to accommodate parts measuring less than 4" in length.
Utilizes 2 HP, 1750 RPM motor.
Variable speed drive is available for brush motor.

B. Semi-Automatic System: The ease of setup and 360° brush deburring action found in the manual deburring machine are also inherent in the semiautomatic machine. Once the operator has loaded the extrusion(s), two palm buttons are pressed. This action initiates the pneumatic clamping mechanism and the table begins its range of motion. By removing operator involvement in the clamping and table traverse mechanisms, operator fatigue has been reduced and cycle time consistency has increased. Once the palm buttons have been pressed this system completes the deburring cycle in approximately 8 seconds. Our testing has shown an average of 3 cycles per minute are possible when loading and unloading are included in the time studies

2. Double End Deburring:

Top

For higher volume production needs, Abtex has engineered a variety of double head end deburring systems, consisting of a deburring machine and a customized set of deburring brushes. As with our single head deburring equipment, the Abtex double head end deburring machines offer increased productivity, quality and safety. Our systems are built to exacting tolerances, and designed to provide reliable service for many years.

A. Return-to-Operator: This RTO system is semiautomatic in design, requiring an operator to load, activate and unload the unit. Two opposing disc deburring brushes are driven by the unit’s 3HP brake motors. The motor assemblies are mounted on a single tool slide to ensure alignment. A reversing brake motor changes the brush direction to provide 360° deburring action. The first pass takes the parts through the top half of the brush, the motor is braked and rotation of the deburring brushes is reversed. The parts are then brought back through the top half of the brush to complete the deburring cycle. Based on field observations, cycle time for this deburring system is approximately 3 cycles per minute to deburr both ends simultaneously.

Standard unit accommodates extrusions measuring from 3 1/2" to 36" in length.
Custom units can be designed to accommodate different ranges of extrusion lengths.

B. Through-feed Systems: The Abtex Double Head Flow-Through System, consisting of a deburring machine and a customized set of deburring brushes, is designed for either semiautomatic or automatic operation.

Model# 2000-F-14

Through-feed systems are designed with two counter-rotating brushes on each side for 360° deburring in one pass.
Parts are loaded on to the conveyor. Finished parts are unloaded from the back of the unit.
Productivity rates of up to 900 parts per hour. Systems are available for a wide range of extrusion lengths.
The most commonly quoted length capacities are:

1" - 3.5"
6" - 48"
3" - 60"

Custom deburring machines can be designed for different ranges of extrusion lengths.

Model# 2000-FS-14

C. Tube Deburring System:

Model# 2000-T-8

Also in our double head end deburring equipment line is our Abtex tube deburring system. The system pictured is a hopper fed unit that deburrs both ends of tubes at a rate of up to 100 tubes per minute. Adjustments are easily made for varying tube dimensions. Once the system is activated, the hopper aligns the work pieces and directs them into the brushes. De-burred tubes exit the back of the deburring machine directly into boxes for shipment or into work bins for easy transport to other work stations. The Abtex tube deburring system is built to customer specifications.

3. Planetary Head (Tri-Ten) Deburring Systems

Top

The Abtex Three-Brush Planetary (Tri-Ten)Head deburring machine has been designed to produce optimal brushing action in through-feed applications. Three, 10" disc deburring brushes offer 207 sq. in. total of abrasive surface area, compared to 151 sq. in. with six, 6" brushes or 75 sq. in. with three,6" brushes. Further, independent variable speed drives allow for job-to-job fine tuning of the rotary head-to-individual brush speed ratio by the system operator.

We also have incorporated a unique, operator-friendly way to change out the deburring brushes on this deburring equipment. There is no threaded bolt or nut retaining the brush from underneath. Instead, the operator simply turns a horizontally located set screw to release or capture the brush via a "knob-headed" retaining pin. This eliminates the need for a spindle lock since the brush and center retaining pin need only be held up in their mounting position during installation and removal.

The Abtex Tri-Ten Deburring System design is the result of extensive lab work and more than 25 years of machine building and brush application experience. Our approach with all equipment is to make deburring machines that are simple in their design, but robust in their construction. The result is overbuilt equipment that performs reliably and effectively over the long term.

4. Rotary Indexing Deburring Machines & Finishing Cells
