Overview
Product Overview
The Ram Milling Machine is designed for flexible machining of medium and large workshop components. Its ram-mounted spindle head can be positioned relative to the table, while the three-axis table movement provides controlled travel for milling, drilling, boring and related operations.
The range includes PRM-5750 and the longer-table PRM-5750A. PRM-5750 has a 500 x 1600 mm table with 1200 mm X-axis travel, while PRM-5750A extends the table to 500 x 2000 mm and X travel to 1400 mm. Both models list 700 mm Y travel, 500 mm Z travel and a maximum loading capacity of 1500 kg.
An ISO50 spindle, 27-step speed range from 30 to 2050 rpm and 7.5 kW main motor support a broad selection of milling cutters. The listed 360-degree swivel arrangement and a spindle-to-arm distance range of 45-745 mm provide setup flexibility for suitable component geometry.
Typical applications include machining plates, fixtures, dies, mould components, frames, housings and maintenance parts. Final selection should consider workpiece and fixture dimensions, combined table load, required travel, cutter size, spindle clearance, material, stock removal, tolerance, surface finish, production volume and installation space.

FAQs
Frequently Asked Questions
What is a Ram Milling Machine used for?
It is used for suitable face milling, slotting, drilling, boring and angular machining of plates, dies, fixtures, housings, frames and general engineering components.
What is the difference between PRM-5750 and PRM-5750A?
PRM-5750A has a longer 500 x 2000 mm table and 1400 mm X travel. PRM-5750 has a 500 x 1600 mm table and 1200 mm X travel. The listed Y and Z travels are the same.
What spindle taper is supplied?
Both models list an ISO50 spindle taper, supporting appropriately matched holders and cutters for the intended operation.
What spindle-speed range is available?
Both models list 27 spindle-speed steps covering 30 to 2050 rpm. Speed selection must suit the cutter, workpiece material, cutting diameter and required finish.
What is the maximum table loading capacity?
The listed maximum is 1500 kg for both models. The combined weight of the workpiece, fixture, clamps and accessories must stay within the approved load and be distributed correctly.
Can the machine handle angular milling setups?
The supplied specification lists a 360-degree swivel arrangement. Confirm how the swivel applies to the selected configuration and verify clearances for the proposed workpiece and cutter.
What are the table feed and rapid speeds?
The listed X/Y/Z feed ranges are 10-1000, 10-1000 and 5-500 mm/min. The corresponding rapid speeds are 2200, 2200 and 1100 mm/min.
What information should be supplied with an enquiry?
Provide component drawings, material, maximum dimensions and weight, required operations, fixture details, cutter sizes, tolerances, finish, production volume, electrical supply and installation-space requirements.
