A Robot Tending Unit keeps the spindle cutting while nobody is standing in front of the machine, which is measured in spindle hours per day rather than in cycle time. The Robot Tending Unit described here is built with a gantry frame and servo Z-axis and specified for job shops running mixed batches. robot integration with custom grippers, guarding and machine interface sits behind the numbers below, which are stated as delivered rather than as a best case.
The parts that matter most are the interfaces: bores, sealing faces, threads and mounting patterns. Those are held to repeatability ±0.05 mm, verified against the drawing, and recorded before anything is packed.

Manufacturing process
The operation sequence is decided before the first chip is cut: roughing to leave even stock, semi-finishing, then robot integration with custom grippers, guarding and machine interface as the final operation. That order is what keeps repeatability ±0.05 mm stable as the batch runs and the machine warms up.
Material is purchased against a certificate and checked on receipt, so the composition is known before any cutting starts. Work in progress is identified by part number and operation, and the finished parts are deburred, cleaned and protected before they leave the machine area.
Typical applications
Most of the work supplied in this category falls into the following examples.
- Loading raw castings into machining centres.
- Unloading finished shafts from lathes.
- Transferring parts between two operations.
- Servicing injection moulding machines.
- Deburring and washing before packing.
Quality control and documentation
Every batch is measured against the drawing with calibrated equipment, and results are recorded against the part number rather than kept on a scrap of paper.
Material certificates to EN 10204 3.1, dimensional reports and first article inspection reports are issued with the shipment where the application requires them. Calibration dates and measurement uncertainty are recorded alongside every result.
Ordering, lead time and packaging
Quotations are returned within one working day of a complete drawing package. Lead time is quoted from drawing approval, not from the date of enquiry.
Frequently asked questions
How much output does machine tending really add?
It converts breaks, changeovers and unattended hours into cutting time. Spindle utilisation typically moves from around 45 per cent to above 80 per cent without changing the process.
What stops a robot cell from running unattended?
Part presentation and recovery, not the robot. Grippers, Input-output handshakes with the machine control and a defined restart routine decide whether faults clear themselves.
What is the minimum order quantity?
One piece for prototypes and first article work. Production pricing usually starts at 50 pieces, and repeat orders run on fixtures retained from the first batch at no extra charge.
To discuss robot tending unit requirements, send the model and the drawing with the quantities required. Feedback on manufacturability is given free of charge before any order is placed.
