RECOIL thread repair inserts.

recoil_inserts

How a Recoil Wire Thread Insert Works: Recoil wire thread inserts are rolled from high quality stainless steel wire with a diamond shaped cross section, wound to the shape of a spring thread. Once the insert is installed into a tapped hole, it provides a permanent and wear resistant thread in the parent material that is stronger than the original thread.

Recoil inserts are greater in diameter than the corresponding tapped hole and compress as they are installed. This allows maximum surface contact area with the tapped thread, safely and permanently anchoring the inserts into place. Read More

Thread taps and their various styles.

hand_tapping

The kind of hole to be tapped has much to do with the style of tap that’s best suited. Some holes go all the way through. Others, while not through holes, still are relatively deep. Some are quite shallow, little deeper than diameter. Each of these three kinds of holes through, deep-bottoming blind, and shallow bottoming, has a tap or group of taps best suited to requirements.

Make the cut with Holemaker PRO 35.

holemaker

The Holemaker PRO 35 is a high quality, compact and robust, fully featured machine. Weighing in at just 10kg, this machine is ideal for those on-site and overhead tasks, whilst the solid, robust construction means the HMPRO35 is perfect for everyday manufacturing type applications.

The 35mm Diameter and 52mm Depth cutting capacity will suffice for most general holemaking requirements. Other standard features include a gravity feed coolant system with a magnetically attached coolant bottle, which can be easily removed and attached to the work piece, allowing coolant feed whilst drilling in horizontal applications.

Basic machining coolant considerations.

Coolant Consideration

Coolant can dramatically affect the performance of cutting tools, which can
impact the cost of your operation. Consider these guidelines for using coolant:

Cutting fluids perform two basic functions in drilling, milling, and threading:
1. to reduce heat generated in cut;
2. to lubricate the tool.

Water-based coolant helps to cool the chip when it is sheared from the workpiece material. Read More

Is your Cutting Fluid friendly to operators?

Rocol-Fluid

All cutting fluids have, to a greater or lesser extent, the potential to cause health issues for machine operators. These risks are based on the external (skin) or internal contact involved in machining work; including the touching of parts and tooling, being splashed by the fluid, having mist settle on the skin or via the inhalation of mist.

The key to minimising this risk is the full evaluation of the machining operation; this process starts with the selection of the most suitable cutting fluid. Read More

Water Hardness and Cutting Fluid.

rocol-water

The overall performance of any cutting fluid emulsion is partially dependant on the quality of the “make water” used to prepare it.

Quality refers to three main features of the water:-

1. Freedom from bacterial contamination
2. Freedom from particular contamination
3. The amount of dissolved calcium and magnesium salts, referred to as total hardness. Read More

How to clean a machine tool system.

rocol-clean

While there are many factors that affect the life of a cutting fluid, such as dilution control, tramp oil, top up rates etc. the key to ensuring maximum sump life from any fresh fill is machine cleanliness.

Why Clean? During use, machine tool fluid systems become contaminated with tramp oil machining debris, hard water soaps etc. which can be found on the sides and bottoms of tanks. These deposits are ideal breeding grounds for both bacterial and fungal infections and eventually become “biomasses” that can shorten fluid life.
