The LMC-G320PS profile grinder is a tool grinding machine designed for the grinding and re-grinding of various types of cutters used primarily in the woodworking industry. There are two grinding systems built into the machine with a separate grinding spindle provided for each. Only one spindle can be used at any time. Two spindles are provided to allow quick change-over without the need for re-mounting of the different types of grinding wheel and guards.
Grinding wheels are not interchangeable between the two spindles. The wheel mountings and guards are of different designs which prevent this.
Profile grinding is used for the grinding and regrinding of shaped profiles onto cutters used for producing timber molding.
The blank cutters are set into the cutterhead prior to profile grinding, and the cutterhead mounted onto the grinder. A 'mirror image'” template, made 1 : 1, ensures that all the cutters are not only ground to the same shape, but they are also in the same position laterally, and as near as possible radially. The finished ground block containing 2, 4, 6, 8 or more knives is transferred to the machine on which it is to be used, without further movement of the cutters.
A bi-linear carriage is used to support the cutterhead on a free rotating arbor, together with the template and dresser unit. A cutter rest is mounted in front of the grinding wheel, and a stylus assembly is situated to the right of the head.
The template is made to match the required timber profile, and the grinding wheel is dressed to match the form of the stylus.
Grinding is a manual operation requiring the operator to control the arbor rotation to keep the cutter in contact with the cutter rest and move the carriage to keep the template in contact with the stylus.
Straight knife grinding is used for the grinding of planerheads and is carried out using the second grinding spindle.
Planerheads are used to plane flat surfaces on timber as distinct from profile cutterheads which are used to produce mouldings. Planerheads always use straight knives to form a cylindrical type of cutterhead - hence the term 'straight knife grinding'.
The straight knives are set into the cutterhead prior to grinding and the cutterhead is mounted onto the machine. A knife guide in front of the grinding wheel is used to control the knife position during grinding.
Grinding is carried out using C.B.N. (Borazon) or diamond wheels with a solid aluminium core. Conventional bonded grit wheels must not be used on this spindle.
Straight knife grinding is a manual operation requiring the operator to control the arbor rotation to keep the cutter in contact with the knife guide, and move the carriage to feed the knife past the grinding wheel. In this case, one carriage axis is locked leaving only the left / right movement under manual control.
Solid profile cutter grinding can also be carried out if the appropriate optional extra equipment is supplied. Solid profile cutters are normally used to produce mouldings but do not involve the use of loose cutters or knives. The required profile is machined into the solid cutter during manufacture and the re-sharpening is done by grinding the face of the cutter.
Three sizes of CBN type wheels are available to suit the required throat depth. For each wheel size there is a guard which includes a cutter location finger (known as the philbus).
The straight knife grinding spindle is used for grinding solid profile cutters. An arbor rotation lock is used to lock the cutter in the position determined by the philbus. One axis of the carriage is locked. Grinding is once again a manual operation but in this case only requires the operator to move the carriage to feed the cutter past the wheel.
A wet grinding coolant system is provided with suitable outlets for all three types of grinding to prevent burning of the cutters and to remove the dust and debris generated during the grinding process.
