MAPAL 推出 EA-Performance-System 精镗刀具系统，覆盖 10 至 19 mm 孔径
MAPAL EA-Performance-System for fine boring tools
MAPAL 推出 EA-Performance-System 精镗刀具系统，把单螺钉调节的 EasyAdjust 原理首次带入 10 至 19 mm 这一技术难度较高的孔径范围。此前经典精镗刀具需要两个调节元件分别设定直径和刃口锥度，对现场操作人员的经验要求较高；EasyAdjust-System 从 20 mm 以上孔径开始采用一根调节螺钉设定直径，并把后锥角永久集成在刀夹系统中。2026 年，MAPAL 通过新的结构设计把这一原理移植到 10 至 19 mm 范围，并称自己是首家面向广泛材料推出该系统的公司。技术实现上，MAPAL 调整了刀片与夹紧系统的连接设计，采用新开发的带确定接触几何的可转位刀片，与配套夹爪配合实现刀片的形状锁合与可重复定位，夹紧机构把调节动作精确传递，并在切削载荷下保持稳定固定。该系统可实现微米级精镗设定，适用于变速箱壳体、缸体、曲轴和凸轮轴上的高精度配合孔与轴承孔，可减少修正工作量、降低废品率。目前已有部分客户在批量生产中使用，并确认了稳定的设定表现和可重复的加工结果。

A technological breakthrough in fine boring
The EA-Performance-System from MAPAL is unique in combining easy setting with maximum precision in the diameter range from 10 to 19 mm
MAPAL is setting a new benchmark in fine boring with the EA-Performance-System. For the first time, easy setting with just one adjustment screw is now available in the demanding 10 to 19 mm diameter range, significantly reducing setting effort while delivering maximum precision.
The setting concept is key
MAPAL has embodied expertise in fine boring for decades. Classic fine boring tools use two adjustment elements for setting diameter and cutting-edge taper, therefore achieving maximum precision. This highly sensitive setting process requires in-depth know-how on the part of the onsite operator and was the starting point when developing the EasyAdjust-System in diameter ranges from 20 mm. With just one adjustment screw for the diameter and a back taper permanently integrated in a cartridge system, it significantly shortens setting times while maintaining high dimensional accuracy and surface quality. It also minimises sources of error.
In 2026, MAPAL is transferring the principle of one-screw setting to the technically demanding diameter range from 10 to 19 mm through a new design configuration. It is also the first company to launch the new EA-Performance-System for a broad spectrum of materials.
Technical design for demanding applications
The design implementation of stable insert fixation with integrated back taper in this diameter range places high demands on system design, manufacturing precision and stability. It requires the insert seat and clamping mechanism to be precisely coordinated. MAPAL has achieved this by adapting the design of the connection between the insert and the clamping system.
At the heart of the innovation is a newly developed indexable insert with defined contact geometry, which, in combination with a matching clamping jaw, achieves positive-locking and reproducible positioning of the insert. The clamping mechanism between the indexable insert and clamping jaw transfers the setting movement precisely and ensures stable fixation under process load.
New benchmark for easy, precise fine boring
In order to meet the highest precision requirements in small diameter ranges, the new EA-Performance-System from MAPAL for the first time enables micrometre-precise setting with easy handling and maximum process reliability. Minimised correction effort, low reject rates and stable machining processes ensure high efficiency in applications like high-precision fit and bearing bores, for example in transmission housings, cylinders, crankshafts and camshafts.
The system is already being used by select customers, where the stable setting behaviour and reproducible machining results have been confirmed in ongoing production.
