SZGHTECH manufactures a dedicated line of grinding and polishing robot arms — the SZGH-M Series — purpose-built for deburring, surface grinding, and polishing of castings, forgings, and machined metal parts across automotive, hardware, valve, and sanitary ware manufacturing. Every SZGH-M grinding robot is a 6-axis articulated industrial robot with payloads from 30 kg to 50 kg and reach from 1,000 mm to 1,850 mm, engineered to hold a grinding wheel, belt sander, or polishing head steady through repetitive, high-force contact with metal surfaces. Each robot ships with a built-in grinding process package — pre-configured motion and force parameters that let operators complete common grinding tasks, including spherical grinding of irregular workpieces, without custom programming from scratch. Replacing manual grinding removes operators from dust, noise, and repetitive-strain exposure while delivering consistent, repeatable surface finish across every part. Free engineering consultation and 24-hour quotation included.
Programming a grinding robot from scratch is one of the hardest automation tasks in metalworking — the robot must maintain constant contact force against an irregular surface while following a complex path, all without gouging the part or losing contact. Every SZGH-M robot ships with a built-in grinding process package: pre-configured force-control and motion parameters developed from SZGH's own production experience.
The package is demonstrated on spherical grinding of irregular workpieces — one of the more difficult grinding geometries — allowing operators to complete common drilling and deburring tasks on non-flat parts without writing custom force-control logic. This shortens deployment time significantly compared with a bare robot arm that requires a third-party grinding software package or in-house programming expertise.
Combined with SZGH's self-developed motion controller (100+ patents), the grinding process package is tuned specifically for SZGH hardware — not adapted from a generic industrial robot platform.

Choosing the right grinding robot comes down to three decisions:
1. How heavy is your workpiece or grinding tool?
If the robot is holding the workpiece against a stationary grinding wheel, size the payload to the heaviest part plus fixture weight — the SZGH-M1000-E-6 (50 kg) covers most heavy castings and forgings. If the robot is holding the grinding tool and the part stays stationary, tool weight (grinder + guard) is usually under 10 kg, so the 30 kg models (SZGH-M1400-3C-6 / SZGH-M1850-3C-6) provide ample headroom.
2. How large is your part or grinding path?
Measure the farthest point the robot must reach without repositioning the part. 1,000 mm covers small-to-medium castings and fittings; 1,400 mm covers mid-size housings and valve bodies; 1,850 mm covers long profiles, large housings, and multi-point deburring paths.
3. Do you need a custom grinding process, or will the built-in package cover it?
For standard deburring and spherical grinding, the built-in grinding process package on every SZGH-M robot covers most common tasks out of the box. For highly specialized finishes (mirror polishing, multi-stage abrasive changes), budget for additional process engineering time with SZGH's application team.
How much does a grinding robot cost?
A complete SZGH-M grinding robot cell — robot + controller + grinding tool interface + safety guarding — typically prices USD 20,000 – 40,000 depending on model and tooling complexity. Free line-itemized quote within 24 hours.
What ROI can I expect vs manual grinding?
Manual grinding and deburring is one of the most labor-intensive, injury-prone processes in metal fabrication (repetitive strain, dust exposure, inconsistent finish). Factories automating with SZGH-M robots typically report consistent surface finish, reduced rework rates, and payback periods of 1.5–2.5 years based on labor savings and reduced scrap from inconsistent manual grinding.
1. Built-In Grinding Process Package
Every SZGH-M robot ships with pre-configured grinding motion and force parameters — no need to build force-control logic from scratch, dramatically shortening deployment time versus a bare robot arm.
2. Purpose-Built for Grinding (Not a Repurposed General Robot)
The SZGH-M Series is a dedicated grinding and polishing platform, distinct from SZGH's general-purpose (T Series) and handling (B Series) robots — engineered specifically for sustained contact-force applications.
3. Widest Payload Range for Heavy Workpieces
The SZGH-M1000-E-6's 50 kg payload handles heavy castings and forgings that many competing grinding robots cannot lift, while the 30 kg long-reach models cover lighter, larger-envelope parts.
4. Proven on Difficult Geometries
The built-in process package is demonstrated on spherical grinding of irregular workpieces — one of the harder grinding geometries to automate — giving confidence for complex, non-flat parts.
5. Self-Developed Motion Controller (100+ Patents)
SZGH's intelligent robot control system is independently developed in-house, tuned specifically for grinding force-control applications rather than adapted from a generic controller.
6. Full CE Certification, Factory-Direct Pricing
CE certified (EN 60204-1, EN ISO 12100, EN ISO 10218), factory-direct from Shenzhen. Typical price 30–50% below Japanese/European grinding robot brands.
Q1: What is a grinding and polishing robot?
A grinding and polishing robot is a 6-axis industrial robot arm designed to perform deburring, surface grinding, and polishing on metal parts with consistent, repeatable force and motion. SZGH's M Series robots range from 30–50 kg payload and 1,000–1,850 mm reach, with a built-in grinding process package for common tasks like spherical grinding.
Q2: How much does an SZGH grinding robot cost?
A complete cell (robot + controller + grinding tool interface + safety guarding) typically prices USD 20,000–40,000 depending on model and tooling complexity. Free line-itemized quote in 24 hours.
Q3: What payload grinding robot do I need?
If the robot holds the workpiece against a stationary grinder, size payload to your heaviest part plus fixture (the SZGH-M1000-E-6 at 50 kg covers most castings). If the robot holds the grinding tool instead, the 30 kg models provide ample headroom since most grinding tools weigh under 10 kg.
Q4: What is a built-in grinding process package?
It's a set of pre-configured motion and force-control parameters that SZGH ships with every M Series robot, developed from real production experience. It lets operators complete common grinding and deburring tasks — including spherical grinding of irregular workpieces — without writing custom force-control programming from scratch.
Q5: Can a grinding robot handle irregular or spherical parts?
Yes. The SZGH-M1000-E-6's built-in process package is specifically demonstrated on spherical grinding of irregular workpieces, one of the more difficult geometries to automate in grinding applications.
Q6: What is the ROI on a robotic grinding cell vs manual grinding?
Manual grinding and deburring is labor-intensive and injury-prone (repetitive strain, dust exposure) with inconsistent finish quality. Factories automating with SZGH-M robots typically report payback periods of 1.5–2.5 years based on labor savings, reduced rework, and consistent surface finish.
Q7: What materials can SZGH grinding robots work with?
Metal castings, forgings, and machined parts across steel, aluminum, stainless steel, and cast iron. Common applications include automotive castings, valve and pipe fittings, sanitary ware, hardware, and engineering machinery components.
Q8: Are SZGH grinding robots CE certified?
Yes. All models carry CE certification (EN 60204-1:2018, EN ISO 12100:2010, EN ISO 10218-1/2). Certificates and test reports available on request.
Q9: What is the difference between the three SZGH-M models?
The SZGH-M1000-E-6 offers the highest payload (50 kg) at a compact 1,000 mm reach, ideal for heavy workpieces. The SZGH-M1400-3C-6 and SZGH-M1850-3C-6 offer 30 kg payload with 1,400 mm and 1,850 mm reach respectively, suited to larger parts and wider grinding paths.
Q10: Does SZGH offer installation and process programming support for grinding robots?
Yes. SZGH's application team assists with grinding tool integration, process parameter tuning beyond the built-in package, and on-site installation. On-site service available in 17+ countries.
