Tool holders for internal turning jobs. Unlike the standard holders that use a 1.5° helix angle, the tool holders that belong to the current product line use 3.5°.

Reamerspeeds and feedsmetric

Tool holders for cutting external threads/grooves. These holders are specially designed to operate in an upside-down position, while keeping the height of the cutting edge at the same level as standard tool holders.

For example, if the speed of the drilling spindle is 500r/min, it is reasonable to set the speed of the reaming spindle to 2/3 of it: 500*0.660=330r/min

There is an experience that recommends setting a thickness of 1~3% of the diameter of the reamer as the reaming allowance (diameter value). For example, a reamer of Φ20 and a hole diameter of about Φ19.6 are more suitable: 20-(20*2/ 100)=19.6 For hard materials and some aerospace materials, the reaming allowance is usually made smaller.

Each element of reaming amount has an effect on the surface roughness of the reaming hole, among which the reaming speed has the greatest influence. For example, reaming with a steel reamer should have a better roughness Ra0. It is said that the reaming speed should not exceed 5m/min, because it is not easy to generate built-up edge at this time, and the speed is not high; and when reaming cast iron, because the chips are broken into granular, no built-up edge will be formed, so the speed can be increased. to 8~10m/min. Usually the spindle speed of reaming can be selected as 2/3 of the spindle speed of drilling on the same material.

The polygon shank tool holders of the Quick Change line are designed to be compliant with the ISO 26623-1 standard for toolholding systems. As such, they can be used with any coupling system that is based on the ISO 26623-1 standard, enabling quick & easy tool changes.

Reaming allowance is the size of the depth of cut reserved for reaming. Usually, the reaming allowance is smaller than the reaming or boring allowance. Too much reaming allowance will increase the cutting pressure and damage the reamer, resulting in the roughness of the machined surface. When the allowance is too large, the coarse hinge and the fine hinge can be separated to ensure the technical requirements.

Tool holders for turning inserts. The holders that belong to the current line of products support only external threads/grooves.

A unique product line of external tool holders equipped with an internal coolant – enabling a flow of coolant to the cutting edge. This reduces the temperature of the cutting edge while machining, helping to extend the life span of the tool. Additionally, the coolant fluid aids in removal of the chips during operation – improving the cutting performance.

Our range of grooving inserts is designed to work with standard Carmex thread turning tool holders, and deliver high-quality grooves. These inserts are manufactured using a variety of blank sizes: 6 mm (5/32″), 8 mm (3/16″), 11 mm (1/4″), 16 mm (3/8″), 22 mm (1/2″), and 27 mm (5/8″).

Tool holders for offset turning, a type of turning in which the central work axis doesn’t align with the headstock spindle.

The feed rate of reaming is larger than that of drilling, usually 2~3 times. The purpose of taking a higher feed rate is to make the reamer cut material rather than friction material. However, the roughness Ra value of the reaming hole increases with the increase of the feed rate. If the feed rate is too small, the radial friction will increase, and the reamer will wear quickly, causing the reamer to vibrate and roughen the surface of the hole.

The so-called reamer is actually boring. The fine boring usually has a unilateral allowance of 0.03-0.1, and the speed is 300-1000. The feed rate of 30-100 is suitable.

On the other hand, if the blank allowance is too small, the reamer will wear prematurely, it will not cut properly, and the surface roughness will be poor. Generally, the reaming allowance is 0.1~0.25mm. For larger diameter holes, the allowance cannot be greater than 0.3mm.

For standard steel reamers to process steel parts, to obtain surface roughness Ra0.63, the feed rate cannot exceed 0.5mm/r, and for cast iron parts, it can be increased to 0.85mm/r.

These carbide shank bars can be used to cut internal threads/grooves. They are especially well-suited for deep small bores with a long overhang, or for use in other situations, where chatter and deflection are expected. These bars have an integrated coolant bore, which helps with chip evacuation. This helps to maximize tool performance, as well as extend the life of the insert.

Typically, one would consider using such a tool holder in case of a large-pitch thread with a relatively small diameter.
