CHEN SOUND Automatic Tool Changer Architecture and Cylinder Lineup

Chen Sound Industrial Co., Ltd. (established in 1980 in Taichung, Taiwan) specializes in CNC automatic tool changers (ATC) and high-force spindle actuation mechanisms.

The product portfolio includes Turntable style cam-driven tool magazines featuring break-motor indexers, high-speed Carousel tool banks with bi-directional hydraulic dampening, high-capacity Chain style tool magazines carrying 24 to 60 tools, and specialized Horizontal tool magazines with 90-degree rotating tool pots.

For tool clamping and unclamping actuation, CHEN SOUND manufactures G4000 series pneumatic-hydraulic booster cylinders delivering 1000 kg to 6000 kg unclamping thrust with integrated spindle air-blast channels, alongside heavy-duty H2000 hydraulic cylinders machined from high-density forged alloy steel for pressures up to 60 bar.

All assemblies withstand continuous duty under exposure to synthetic coolants, cutting oil mists, and metallic swarf.

Engineering Selection Guidelines for CHEN SOUND Tool Magazines and Actuators

Selecting CHEN SOUND automatic tool changers requires verifying machine mounting interfaces, spindle taper standards (BT30, BT40, BT50, HSK, CAT), and required tool pocket capacity.

Compact three-axis machining centers utilize Turntable disc magazines holding 16 to 24 tools with 0.8-second cycle times. Heavy horizontal machining centers carrying face mills weighing up to 25 kg employ Chain style or Flat style magazines supported by dual-side heavy-duty linear tracks.

Selecting G4000 booster cylinders involves calculating required drawbar release force to compress internal spindle disc springs with at least a 20 percent safety margin. Engineers verify required unclamping stroke lengths between 8.5 mm and 17 mm across 2T, 2.5T, 4T, and 5T tonnage ratings.

SpareX coordinates technical engineering verification and direct international delivery of direct factory units.

Field Commissioning and Diagnostic Alignment for CHEN SOUND ATC Systems

Field engineering inspection encompasses laser alignment between the tool changer gripper arm and the machine tool spindle centerline to prevent mechanical impact against tool holders.

Technicians inspect radial runout on tool discs, check hydraulic damper response times, and verify smooth linear traverse across magazine carriage linear guides.

During commissioning, technicians integrate magazine home position sensors into machine tool CNC controllers, optimize pneumatic solenoid valve actuation delays, and check operating pressure stability in G4000 booster circuits.

The integrated spindle blow-off cycle is calibrated to purge fine chips from spindle tapers before new tool seating.

Periodic Maintenance Guidelines and Wear Inspection for CHEN SOUND Units

Routine maintenance protocols for CHEN SOUND tool magazines mandate clearing coolant deposits from tool pot tapers, measuring backlash across roller chains and cam indexing gearboxes, inspecting composite tool gripper clips, and torquing mounting fasteners to specification.

Technicians inspect synthetic gear grease levels in sealed tool drum indexing housings.

Inspection of G4000 booster cylinders and H2000 hydraulic units includes verifying thrust retention using dynamic drawbar force gauges, inspecting for internal hydraulic oil bypass, and monitoring rod surface condition.

If unclamping force diminishes or return stroke velocity degrades, technicians disassemble cylinders, inspect bore finishes, and renew high-pressure polyurethane packing seals.

Tool Changer Kinematic Alignment and Phase Synchronization Procedures

Kinematic alignment of CHEN SOUND tool changers begins with mechanical height adjustment of the gripper arm relative to spindle tool flange grooves at zero degrees transfer angle.

Technicians utilize dial test indicators on master arbors to align radial and axial runout within machine specification tolerances. Movement phases synchronize with CNC controller cycles via proximity limit switches.

On G4000 booster cylinders, technicians adjust the threaded extension bolt on the strike piece to maintain precise direct contact against the tool retention knob during stroke actuation.

The integrated air-blowing valve timing is tuned so that the compressed air jet purges the spindle socket precisely as the taper disengages.
