SZGH G1000-B-4 — 4-Axis Compact Handling Robot

What Is the SZGH G1000-B-4?

The SZGH G1000-B-4 is a 4-axis industrial handling robot rated for a 6 kg payload and a 1,000 mm reach, engineered by Shenzhen Guanhong Automation for high-speed pick-and-place, stamping press tending, and small-part palletizing tasks where a full 6-axis wrist is unnecessary and a lighter, faster, lower-cost arm delivers superior throughput.

Core Advantages

4-Axis Architecture — Faster, Simpler, Lower Cost

The B Series omits Axes 5 and 6 (wrist pitch and roll) that 6-axis robots carry. For handling and palletizing tasks that do not require complex wrist reorientation, this means fewer joints, fewer servo drives, fewer potential failure points, and a significantly lower price. Maintenance teams with basic electro-mechanical skills can service all four axes without specialist training.

Axis 4 at 400°/sec — Match the Fastest Stamping Cycles

Axis 4 (the end-effector rotation axis) reaches 400°/sec — twice the speed of Axes 1–3. In high-cadence stamping press applications where the press runs 18–22 strokes per minute, the robot can complete its wrist repositioning between pick and place without becoming the cycle-time bottleneck. This is a direct performance advantage over lower-speed 4-axis configurations at the same price point.

Three Mounting Modes Including Ceiling-Inverted

The G1000-B-4 is the only B Series model to support ceiling (inverted) mounting in addition to ground and bracket configurations. Inverted installation on a ceiling track or overhead frame means the robot occupies zero floor space, enabling integration into facilities where floor real estate is scarce or where the press bed and conveyor leave no room for a ground-mounted base.

60 kg Body Weight — Relocate Without a Crane

At approximately 60 kg, the G1000-B-4 is the lightest robot in the B Series. A two-person installation team can position, level, and bolt down the robot using standard mechanical handling — no overhead crane required. When production layouts change, the same team can relocate the robot in a single shift, protecting your capital investment when line configurations evolve.

±0.2 mm Repeatability — Sufficient for All Handling Tasks

For handling, press tending, and palletizing, ±0.2 mm repeatability is the correct specification — there is no process benefit to the ±0.05 mm tolerance required in welding or precision assembly. SZGH G1000-B-4 delivers a specification matched to the application, not an over-engineered (and over-priced) alternative.

Application Scenarios

B Series Internal Comparison — Which Model Is Right for You?

Selection guide: If payload ≤6 kg and space is limited or ceiling mount is needed → G1000-B-4. If payload 7–10 kg and the primary task is stamping press tending → B1500-C-4. Scale up the series as payload and reach requirements grow.

Customer Case Study

By Fannie Chen, CEO, Shenzhen Guanhong Automation Co., Ltd. (SZGH)

"One of the most satisfying deployments I have worked on with G1000-B-4 was with an automotive stamping subcontractor in Monterrey, Mexico. The facility ran a bank of small stamping presses outputting brackets and clips at 18–22 strokes per minute. Prior to automation, two workers rotated shifts to keep up with the press cadence — and hand injuries from mis-timed retrieval were a recurring problem that generated workers' compensation claims every quarter.

The G1000-B-4 was installed on a wall bracket directly beside the press — not on the floor, because the floor in front of each press was occupied by the outfeed conveyor. The bracket mount kept the robot out of the operator walkway and the ceiling clearance was comfortable for the inverted arm envelope. Axis 4 running at 400°/sec matched the fastest press cadence without compromising the cycle time.

What I remember most is how quickly the integration went. The G1000-B-4 body weighs only 60 kg. The customer's own two-person electrical team completed mechanical installation and initial teach-in over two days — they did not need to fly in a specialist or halt other production lines. Within the first month of operation, the two workers who had previously tended the press were reassigned to quality inspection roles. The hand injury claims stopped. Cycle consistency improved, and the customer reported a payback period under 14 months."

Frequently Asked Questions

Q1: Why choose a 4-axis robot instead of a 6-axis robot for stamping press loading?

For stamping press tending and part transfer, the workpiece typically needs to move from Point A to Point B with a consistent orientation — the gripper does not need to twist, tilt, or adopt complex wrist angles. A 4-axis robot covers this motion profile completely. The benefit: 4-axis robots are mechanically simpler, cycle faster (fewer axes to interpolate), cost less to purchase, and are easier to maintain. Paying for Axes 5 and 6 that a stamping application will never use is unnecessary overhead.

Q2: Is ±0.2 mm repeatability sufficient for press tending?

Yes. Stamping press tending requires the gripper to reliably pick a part from a die or conveyor and place it into a stack or next station. Dimensional tolerances in stamping are typically ±0.5 mm or wider. ±0.2 mm repeatability means the robot's return-to-position error is smaller than the part tolerance — the robot is not the limiting factor. The tighter ±0.05 mm specification required for welding or precision assembly adds cost and is unnecessary here.

Q3: Can the G1000-B-4 be mounted on the ceiling?

Yes. The G1000-B-4 is the only B Series model to support ceiling (inverted) mounting. This is particularly useful when press beds or conveyors occupy all available floor space. The ceiling-mounted configuration requires a reinforced overhead structure rated for a dynamic load of at least 300 kg (robot weight plus dynamic forces). SZGH provides a mounting flange drawing and load specification sheet for structural engineer review.

Q4: How does the G1000-B-4 compare to the B1500-C-4?

The G1000-B-4 targets applications with payloads up to 6 kg and requires compact installation (including ceiling mount). The B1500-C-4 targets heavier parts (up to 10 kg) and a longer reach (1,500 mm) for stamping lines where the robot must reach across a wider work zone. If your parts weigh under 6 kg and space is tight, the G1000-B-4 is the better-value choice. If payloads are 7–10 kg or reach exceeds 1,000 mm, step up to the B1500-C-4.

Q5: What is the minimum cycle time the G1000-B-4 can achieve?

Actual cycle time depends on move distance, payload, and acceleration parameters. In typical press-tending pick-and-place cycles with a 500 mm move and 6 kg payload, the G1000-B-4 achieves approximately 0.8–1.2 seconds per cycle (pick + move + place + return). With Axis 4 at 400°/sec, wrist repositioning between pick and place adds minimal time. Final cycle time should be validated in a simulation or factory acceptance test with the actual application trajectory.

Q6: Does SZGH provide application programming and commissioning support?

Yes. SZGH provides remote commissioning support via WhatsApp and video call (24/5). For customers purchasing through an agent (USA, Turkey, Romania, Russia, Egypt, Thailand, Mexico), on-site commissioning can be arranged through the local agent. Programming training (teach-pendant operation and SZGH Robot Language basics) is included with the delivery documentation.

Q7: What gripper should I use for ferrous stamping parts?

For ferrous (steel/iron) stamping parts, a magnetic gripper is typically the fastest and most reliable option — it picks without requiring precise part alignment and releases cleanly on command. For non-ferrous parts or parts with complex geometry, vacuum cup grippers are standard. SZGH can advise on end-of-arm tooling selection based on part weight, material, surface finish, and cycle time requirements. Contact us with part drawings and cycle rate for a recommendation.

Q8: Can the G1000-B-4 communicate with our existing PLC or MES system?

Yes. The SZGH controller supports Modbus TCP and RS-485/RS-232 natively. PROFINET and EtherNet/IP interfaces are available as options. For MES integration, the controller exposes a set of register addresses for robot status, alarm codes, program number, and I/O states that can be polled by the MES host. A communication protocol document is provided in the delivery package.
