Designed for industries such as automotive, aerospace, shipbuilding, and hydraulics, these solutions enhance productivity, ensure consistent accuracy, and streamline complex tube processing tasks.

Circular & Long Seam Milling Machines,
and Weld Preparation

These machines are used to machine a perfect weld prep and remove the tacking lay with the help of a side milling cutter and have become standard at the leading thick plate operators worldwide due to the enormous advantages this process offers. Comparing to the grouting with carbon rods and grinding, advantages are: the costs per metre welding seam can be reduced in part by more than 50 percent (shorter processing time of the seam preparation, reduction of welding material needed, reduction of welding time and a considerably lower energy consumption), the surface quality is higher and the geometry of the seam volume is more regular. Furthermore, the subsequent welding process can be automated, the working conditions are improved and the chips, which occur during the milling, can be recycled.

Belt Grinding & Deburring Machines

This is a high performance belt grinding machine, where the plate is clamped electromechanically on a supporting table. The grinding unit moves on a rail system and the bevel is ground in one or more passes on the upper side of the plate. The bevel angle is stepless adjustable. A special table unit can be used for working on bigger plates.

Coolant Monitoring & Cleaning Units

Protube has a wide range of equipment to help maintain the coolants in top condition. Clean coolant has a longer life, gives better results and contributes to healthier working conditions.

Dosing Units

Dosing pumps ensure accurate dosing of different oil types when filling or topping up tanks installed on traditional machines or machines with numerical control. A good dosing technique prevents premature wear of tools while contributing to the quality of the general machining produced.

Fire Resistant Hydraulic Fluids
& Heavy Duty Hydraulic Oils

High water content (HFA) fluids are ideal for use in steel mills, underground longwall mining equipment and any other hydraulic system designed for water hydraulic equipment. Water glycol (HFC) fluids are the most widely used fire resistant hydraulic fluids. They offer outstanding price/quality and combine fire resistant properties with reasonable lubrication performance.

Mist Collection Devices

The MistBuster range are mist collectors designed to capture and clean mist and smoke from metalworking applications in industry. Patented technology insures high efficiency with no disposable filters in a compact machine mounted package. A variety of mounting options on these mist collectors allow for maximum versatility. Advances in modern CNC machines have increased productivity and increased the need for better lubrication in order to keep up with the faster spindle speeds. These advances have also led to an increase in metalworking fluids being generated and emitted into the air. These airborne fluids can pose a serious health threat to the employees in the metal working industry, so mist extraction becomes important.

High Pressure Cooling Units

We offer high quality, high pressure coolant systems. Through extensive testing, we have gained the technical expertise to provide you with longer tool life, longer coolant life, superior chip control, more part throughput and faster cutting speeds. These advantages commonly show a significant reduction in the payback period on new machine tool equipment, tooling, services and filtration products.
