A Horizontal Milling Machine removes material with a rotating cutter, producing pockets, slots, contours and three dimensional surfaces. The Horizontal Milling Machine described here is built with a 4-axis rotary table and probing and specified for aerospace suppliers. CNC milling with adaptive roughing and finish passes 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 ±0.02 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 CNC milling with adaptive roughing and finish passes as the final operation. That order is what keeps ±0.02 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.
- Mould and die cavities.
- Machine base plates.
- Aerospace ribs and spars.
- Impeller and blisk roughing.
- Instrument panels and enclosures.
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
What is the difference between 3, 4 and 5 axis?
Three axis machines cut prismatic parts; a fourth rotates the part for features around a cylinder; five axis tilts the cutter or table so compound angles are reached in one setup.
How is surface finish controlled?
By the stepover, the cutter geometry and the final finishing pass. Ra 1.6 µm is routine, and Ra 0.8 µm is achieved with a fine stepover and a sharp, balanced tool.
Can you supply material and inspection certificates?
Yes. Material certificates to EN 10204 3.1, full dimensional reports, first article inspection reports and, where required, PPAP or AS9102 documentation are issued with the shipment.
