Equipment for cylindrical shaping of logs

Cylindrical shaping of logs is the most popular way of wood processing in blockhouse building today. Blockhouses made of cylindrically shaped logs are the traditional housing for Slavs. In ancient days logs were rounded with an ax, but today time and progress have replaced the ax on machines for cylindrical shaping of logs.

Modern machines for cylindrical shaping of logs, can be divided into two groups depending on processing method - the submission type (or rotary) and turning-milling type.

Submission type machines for cylindrical shaping of logs offer high performance but have low accuracy, a relatively large roughness of processed surface due to deficiencies in system of basing, expensive (due to their exclusivity and complexity of manufacture) parts and supplies, high power consumption. Preparation of log is necessary prior to processing with submission type machines for cylindrical shaping of logs. Turning-milling type machines for cylindrical shaping of logs are characterized by high accuracy and good quality of processed surface, while their productivity is lower than submission type machines have. They have a solid system of basing, occupy little place at production area, have relatively low power consumption and can process a workpiece of any original curve and gnarly shape into smooth log. In addition, the turning-milling type machines for cylindrical shaping of logs usually are equipped with unit for excising crowned cross-notch cups.

Equipment for cylindrical shaping of logs works in complex with notching machines or as they are called cup excising machines. Depending on the cutting tools cup excising machines are of two kinds: milling type and band type.

Milling type cup excising machine cuts a cup with milling cutter - knife type or crown type. Obtained cup is of regular shape and the specified dimensions. Some inconvenience in operating with such cup excising machines include tool change when the cup size is changed (each cup diameter requires individual cutter and knives), and the presence of "fringe" on the edge of crowned cross-notch cup at work with knife cutter. In addition, milling type cup excising machines consume much more power than the band type.

Band type cup excising machines are much less common than milling type. Band type machine cuts a crown cup with narrow band-saw, so called "fretsaw", welded in a circle. Obtained edges of cup are smooth, without fringe, shape and sizes match specifications. Most of these machines allow excising cups of almost any diameter without changing of cutting tool. Disposable fretsaw can be considered as disadvantage in use of band type machines - with blunt cutting edge, fretsaws are generally not subject to re-sharpening.

Research-Production Association "Group of companies" MAGR "produces woodworking machines for cylindrical shaping of logs, as well as cup excising machines and devices since 2001. MAGR guarantees the reliability of machines, ease of their use and quality of products manufactured due to many years of experience in the design of equipment, advanced manufacturing capabilities, multi-level quality control system, and constant feedback from customers, exploiting the equipment for cylindrical shaping of logs.
